Developing a web user control

 Does Web user control  really fastens the the development process.?

I have answer for this ,this is one of the area which fastens the developement process bcoz we may be repeatdly using some components or controls in the entire project,suppose a gridview with some functionality or calendar control with some functinality or a adrotar  or  login control.

So developing of user control will be one time ,which we can repeadtly use in our entire application.Now let us see how to develop a web  user control.

1. Go to your visual studio File-> New-> Website-> give the name for yourproject and specify the location
2. Now open the solution explorer(ctrl+w,s),right click on the project ->Add new item ->Now select Webuser control from the screen(the extenstion will be .ascx) name it to coustomcalendar.
3. Now got to design view of coustomcalendar.ascx  and drag a drop a calendar and  on to your screen.Now your code should look below

--------------------------------------------------------------------------------------------------------

--------------------------------------------------------------------------------------------------------

Now  here we are making a calendar  control which displays date on the label after you select  the date from calendar.
Also it  makes weekend selection true or false based on property we set

Now code to display date in the lable when date in calendar is selected will be in calendar selection changed event.Double click on calendar in coustomcalendar.ascx.
The code for the selection changed ecvent is as below
--------------------------------------------------------------------------------------------------------
protected void clndr_weekend_SelectionChanged(object sender, EventArgs e)
    {
        lbl_date.Text = clndr_weekend.SelectedDate.ToString("yyyy-MM-dd");
    }
--------------------------------------------------------------------------------------------------------
 Now am going to declare a property to make weekend selection true or false.
----------------------------------------------------------------------------------------------------------

    private bool _isweekendselectable;

    public bool Isweekendselectable
    {
        get { return _isweekendselectable; }
        set { _isweekendselectable = value; }
    }
 --------------------------------------------------------------------------------------------------
 I declared a property ,now i have to make the weekend dates enable true/false based on  property.
 This magic is done in dayrender event on calendar event.
----------------------------------------------------------------------------------------------------
protected void  clndr_weekend_DayRender(object sender, DayRenderEventArgs e)
{
    if (!Isweekendselectable)
    {
        if (e.Day.IsWeekend)
        {
            e.Cell.Controls.Clear();
            e.Cell.Text = e.Day.DayNumberText;
        }
    }
}
---------------------------------------------------------------------------------------------------------
Now we are done with using control,let us summarize the steps

1. Adding  webusercontrol  by going to new items
2. Drag and  Drop a claendar and label control
3. Write a code in calendar selection changed event to display date in label.
4. Create a property to make weekends enabled true/false
5. Write a code in calendar dayrender event  to  make weekends enabled true/false

Now let us test the web  usercontrol created .

1. Go to default.aspx->go to   designe view->drag the coustomcalendar.ascx from solution explorer on to your page.
2. Now go to properties(f4) and you can find property named IsWeekendselectable change it to true/false and test.

Happy coding ;)
