Dear All,

I am trying to learn user control ans also found some articles on web.

As I am not so much aware of web user contol.

I am not getting how this code works/flows. Simply not getting code.

For example in given link there is a example of custom GridView in which there is one method OnPageIndexChanging.

But where is code of OnPageIndexChanging method.

In given code parameters are passed to this method for changing page index,for changing page page size etc.

But i am not getting how this works and where is code.

Please see the link.

Solution 1

It's a custom grid, so it's inheriting from GridView. It's simply raising the base class event OnPageIndexChanging, the declaration for that is in GridView. Use the IDE to browse the definition of the event (right mouse over OnPageIndexChanging -> go to defintion) and you will see where it is.

From the other comments there, it looks like the author hasn't included the js file.

Solution 2

Basically any event is empty by default. we need to define the code in that events to carried it out.
Lets check about your Paging.

Have you define OnPageIndexChanging event on Page.
If yes then write following code in PageIndexChanging.

C#

GridView1.PageIndex = e.NewPageIndex;
//Bind grid Again.

To use paging in GridView you need to take care of following things
1. Give PageSize.
2. write PageIndexChanging event.
