Well, using RoundCornerExtender became a headache for me when i had to use it all over the page on different sections using a Panel (Div). Each Panel had to have padding to keep a distance between the content and the border of the Panel and margin to keep reasonable distance between two Panels.

Anyway, giving padding or margin really ruined the idea and the entire Panel was distorted. I am not sure if there is a quicker method to fix it but there is a work around and that is buy using 3 Panels.

There should be one outer panel and two panels inside that outer one. Give margin to the most outer Panel and padding to the inner most Panel. but here is the catch, Roundedcornersextender has to be associated with the middle Panel and give middle panel 0 padding and 0 margin so that it doesn’t inherit any styling from its parent panel (margin).

Outer and inner most Panels can be replaced with the client side div (easy to handle with javascript due to static Ids)

Its a small workaround, i hope it helps

HTML:

<div id=”divOuter” class=”round_outer_panel”>

  <asp:Panel ID=”divRound” runat=”server” CssClass=”round_middle_panel”>

        <div id=”divContent” class=”round_inner_panel”>

                content goes here..

        </div>

  </asp:Panel>

  <cc1:RoundedCornersExtender ID=”RoundedCornersExtender2″ runat=”server” Radius=”4″ TargetControlID=”divRound”></cc1:RoundedCornersExtender>

</div>

CSS:

.round_outer_panel

{   

    margin: 5px 5px 5px 0px;   

    width: 100%;

}

.round_middle_panel

{   

    padding: 0px;   

    margin: 0px;

    width: 98%;

}

.round_inner_panel

{   

    padding: 10px 20px 10px 20px;            

    width: 90%;

}

Cheers -

Now this is useful only if you don’t want to use Database for storing dropdownlist’s values, otherwise i would prefer using it DB or XML.

I’ll jump directly to the code, I hope you are not a newbie

Enum for the type of dropdownlist to be filled:

public enum DDLType
{
Education = 1,
Experience,
Salary,
}

Filling dropdownlist based on enum value

public class UtilityManager
{

//place for utility functions and inner classes…

//Inner class for all the functions related to server side controls..
public class ControlsManager
{
public static DropDownList FillDropDownList(DropDownList ddl, DDLType type)
{
switch ((int)type)
{
case (int)DDLType.Education:
ddl.Items.Add(new ListItem(“Not Specified”, “1″));
ddl.Items.Add(new ListItem(“None”, “2″));
ddl.Items.Add(new ListItem(“High School”, “3″));
ddl.Items.Add(new ListItem(“Diploma”, “4″));
ddl.Items.Add(new ListItem(“2 Year Degree”, “5″));
ddl.Items.Add(new ListItem(“4 Year Degree”, “6″));
ddl.Items.Add(new ListItem(“Graduate Degree”, “7″));
break;

case (int)DDLType.Experience:
ddl.Items.Add(new ListItem(“Not Specified”, “1″));
ddl.Items.Add(new ListItem(“Fresh/Internee”, “2″));
ddl.Items.Add(new ListItem(“Less than 1 year”, “3″));
ddl.Items.Add(new ListItem(“1-2 Years”, “4″));
ddl.Items.Add(new ListItem(“2-4 Years”, “5″));
ddl.Items.Add(new ListItem(“4-6 Years”, “6″));
ddl.Items.Add(new ListItem(“6-8 Years”, “7″));
ddl.Items.Add(new ListItem(“8-10 Years”, “8″));
ddl.Items.Add(new ListItem(“10+ Years”, “9″));
break;

case (int)DDLType.Salary:
ddl.Items.Add(new ListItem(“Not Specified”, “1″));
ddl.Items.Add(new ListItem(“$10,000″, “2″));
ddl.Items.Add(new ListItem(“$20,000″, “3″));
ddl.Items.Add(new ListItem(“$30,000″, “4″));
ddl.Items.Add(new ListItem(“$40,000″, “5″));
ddl.Items.Add(new ListItem(“$50,000″, “6″));
ddl.Items.Add(new ListItem(“$60,000″, “7″));
ddl.Items.Add(new ListItem(“$70,000″, “8″));
ddl.Items.Add(new ListItem(“$80,000″, “9″));
ddl.Items.Add(new ListItem(“$90,000″, “10″));
ddl.Items.Add(new ListItem(“$100,000″, “11″));
ddl.Items.Add(new ListItem(“$110,000″, “12″));
ddl.Items.Add(new ListItem(“$120,000″, “13″));
break;
}
return ddl;
}

Getting the text for the selected value of the dropdownlist:

public static string getDDLTextValue(string value, DDLType type)
{
DropDownList ddl = new DropDownList();

switch ((int)type)
{
UtilityManager.ControlsManager.FillDropDownList(ddl, type).Items.FindByValue(value).Text;
case (int)DDLType.Experience:
return UtilityManager.ControlsManager.FillDropDownList(ddl, type).Items.FindByValue(value).Text;
case (int)DDLType.Salary:
return UtilityManager.ControlsManager.FillDropDownList(ddl, type).Items.FindByValue(value).Text;
default:
return null;
}
}

   } //Controls manager ends..
} // Utility manager ends..

How to use it? Filling all dropwonlists.

UtilityManager.ControlsManager.FillDropDownList(ddlCurrentSalary, DDLType.Salary);
UtilityManager.ControlsManager.FillDropDownList(ddlExpectedSalary, DDLType.Salary);

Get the text for selected value.

UtilityManager.ControlsManager.getDDLTextValue(ddlExperience, DDLType.Experience);

Short and simple!!!!

This is a custom built reusable SessionManager Class to keep track of all the used session variables in a web application. You don’t need to remember them or type them by hand every time you need to access them and with typed dataset rows, life becomes allot more easier but above all there is no need of casting where ever you access a session object, believe me, that’s the best part.

public class SessionManager
{
    //set the login status in session for the current user.
    public static void setIsLoggedIn(bool value)
    {
        //value is true when the the usser logs in
        HttpContext.Current.Session["isLoggedIn"] = value;
        //value is false when the the usser logsout
        if (!value)
            HttpContext.Current.Session["isLoggedIn"] = null;
    }

     //check to see if the user is logged in

    public static bool isLoggedIn()

    {

        if (HttpContext.Current.Session["isLoggedIn"].Equals(null))

            return false;

        else

            return true;

    }   

    //set current employee in the sessoin

    public static void setCurrentEmployee(dsEmployees.EmployeesRow value)

    {

        HttpContext.Current.Session["Employee"] = value;

        if (value != null)

        {

            //following variables are set separately to be used in bindable control like

            //GridView, DataList etc..

            HttpContext.Current.Session["EmployeeId"] = value.EmployeeId;

            HttpContext.Current.Session["Name"] = value.FirstName + ” “ +

                value.MiddleName + ” “+ value.LastName;

        }

    }

    //get current employee fro the session

    public static dsEmployees.EmployeesRow getCurrentEmployee()

    {

        return(dsEmployees.EmployeesRow)HttpContext.Current.Session["Employee"];

    }

    //bonus functions – to be used on the pages where it is neccessary for the users to login

    public static void setRedirectUrl(stringredirectURL)

    {

        HttpContext.Current.Session["redirectURL"] = redirectURL;

    }

    //bonus functions – once the users log in, they will be redirected back to the previously

    //stored url or redirected to the default page

    public static stringgetRedirectUrl()

    {

        if (object.Equals(HttpContext.Current.Session["redirectURL"], null))

            return “myaccount.aspx”;

        else

            return HttpContext.Current.Session["redirectURL"].ToString();

    }

}

Analyze one thing that setCurrentEmployee is taking the entire typed dataset’s row of the currently logged in user. This practice helps a great deal to quickly access any value from the currently logged in user’s details instead of hitting the database again and again and of course, typed datarow helps you avoid any mistakes in writing field names

Here is a sample code to set and get login sessoin variables.

    {

        Page.Validate();

        if(!Page.IsValid)

            return;

        dsEmployeesTableAdapters.EmployeesTableAdapter ta = new dsEmployeesTableAdapters.EmployeesTableAdapter();

        dsEmployees.EmployeesDataTable dt = ta.Login(txtuid.Text.Trim(), txtPassword.Text.Trim());

        if(dt.Rows.Count > 0)

        {

            dsEmployees.EmployeesRow row = dt[0];

 //set current user as logged in

    return;

    }

Now it is very easy to check if the user is logged in.

//check if the user is logged in

        if (!EmployeeSession.isLoggedIn())

        {

            //store current url and redirect to the login page

            stringurl = Request.Url.AbsoluteUri.ToString();

            EmployeeSession.setRedirectUrl(url);

            Response.Redirect(“login.aspx”);

        }

Accessing the data of the currently logged in user is piece of cake now. 

          //check if the user is logged in
            if (EmployeeSession.isLoggedIn())
            {
                //display the name of the user from the session object
                lblName.Text = SessionManager.getCurrentEmployee().Name;
            }

Hope it helps, if you need more on it, drop me a few lines.

Both DataSource and DataSourceID are defined on ‘GridView1′.  Remove one definition.

OK, so this is the message that you get most of the times when you try to bind your gridview or any other bindable controls, to multiple DataSources.

 It happens most of the times when you bind your GridView control to an ObjectDataSouce or SqlDataSource on the design surface and then you try to bind the same GridView in code behind using the manual coding and sometimes it becomes necessary to do so in the scenarios of searching and manual paging etc.

(Binding to ObjectDataSource)

 

(Binding to manual DataSource)

GridView1.DataSource = null;
GridView1.DataSource = myDataTable;
GridView1.DataBind();

This is not going to solve the problem, the simples workaround is to set the DataSourceID to null.

GridView1.DataSourceID = null;
GridView1.DataSource = dt;
GridView1.DataBind();

now this is going to work perfectly fine but DataGrid required a page developer to write custom code to handle simple operations such as paging, sorting, editing or deleting data, the GridView control can automatically handle these operations provided its bound data source control supports these capabilities and we know that this kind of custom binding will kill any chances to automate your GridView to handle all these operations automatically.

Simplest way to resolve this issue is to display your required data to the client and then bind back the GridView to your original datasouce by setting the DataSourceID to null again. That will bring back all your automation functionality back to the GridView.

I love some of the new features in c#, specially the syntactic changes and enhancements are great to achieve greater productivity (I have my own reservations on the efficiency though, but that’s debatable)

Lets take a look at the new Object initializers in C#

Now you can assign values to any accessible properties (fields) of an object at its creation time. It actually avoids the necessity of invoking the constructor to do so.  lets take a look at an example with a name type before moving on to the anonymous types.

private class Student
{
    // Auto-implemented properties (We’ll discuss them in the next post of this series)
    public int Name { get; set; }
    public string RegistrationNumber { get; set; }
}

static void NewStudent()
{
    // Object initializer
    Student student = new Student{ Name = “Khan”, RegistrationNumber = 7728 };
}

Object initializers are very useful with LINQ query expressions. Query expressions use anonymous types frequently which can only be initialized through object initializers. This is very useful when you want to store some of the selected information for each object in a collection.

 with Let’s take a look at the anonymous object initializers example.

var students =
    from s in students
    select new { s.Name };

Continuing from my previous example, this time in students collection we need to store only names not the registration number.

That’s a quick and easy one, wait for more :)

The new var type in c# 3.0 and anonymous types will help developers a great deal in extending their programming capablities and creat obejects on the fly without actually writing classes.

Existing .NET developers may have some reservations on the new var type but believe me alot of new commers from the open source world, specially PHP, would love to have this feature to get some familiarity, which otherwise is not there at all for them in .NET platform.

Anyway, for thoe who have no idea of what i am talking about here is a small code snippet to have a better understanding.

var myAnnonynomousItem = new {car=“lexus”, color=“black”, maxSpeed=4200}

Compiler generates a classes for every annonymous type automatically.

One thing has to be kept in mind here that var is definitely an implicit type but not the variant type so once a value of a particular type is assigned to a var type variable, another type of value cant be assigned to it.

var myVal = 22;
myVal = “Panda”;

There are some very significant differences between var and object types. An object type gives you this facility to hold different type of values in the same object that var doesn’t as explained above for example in object type you can

object myObjectTypeVal = 32;
myObjectTypeVal = “Panda”

On the other hand you cannot perform mathmatical operators with object type but you can do that with var type for the same type of object.

object myObjectTypeVal = 32;

var myVal = 22;
myVal += 22;

I hope it helped.

Cheers!

Well, I thaught i wasn’t going to write any javascript this time and lets make a general function which can take any parent control and reset all the sub controls. The functoin can definitely be extended to add more parent and sub controls type but this is just a kick start

public static void resetAllControls(object parent)

    {

        if (parent is HtmlTable)

        {

            HtmlTable tbl = (HtmlTable)parent;

            foreach (HtmlTableRow row in tbl.Rows)

            {

                foreach (HtmlTableCell cell in row.Cells)

                {

                    foreach (Control ctrl in cell.Controls)

                    {

                        if (ctrl is TextBox)

                        {

                            ((TextBox)ctrl).Text = string.Empty;

                            ((TextBox)ctrl).Enabled = true;

                            ((TextBox)ctrl).Visible = true;

                        }

                        if (ctrl is CheckBox)

                        {

                            ((CheckBox)ctrl).Checked = false;

                            ((CheckBox)ctrl).Enabled = true;

                            ((CheckBox)ctrl).Visible = true;

                        }

                        if (ctrl is DropDownList)

                        {

                            ((DropDownList)ctrl).SelectedIndex = 0;

                            ((DropDownList)ctrl).Enabled = true;

                            ((DropDownList)ctrl).Visible = true;

                        }

                    }

                }

            }

        }

    }

it is very useful to be used inside update panel.

Yeah, I was looking for the easiest way to publish my database entirely with schema plus data to my online server. Here is a handy tool to install and use with excellent GUI.

Download the database publishing wizard 1.1 here.

It is so easy that I guess i dont have to write any tutorial/steps to use it but yet some screenshots might be useful for newbies
