Question

According to my book all that is needed to start using automatic paging is to set GridView.AllowPaging to true. But when I try to navigate to another page, I get GridView fired event PageIndexChanging which wasn’t handled exception. I then have to create event handler for PageIndexChanging event, but then when I navigate to next page, GridView doesn’t display anything.

Q1 – What am I doing wrong?

Q2 – Book is written for Asp.Net 3.5, but none of the behavior described above is mentioned by the author?! Any thoughts why my GridView behaves so differently?

thanx

EDIT:

I’m embarassed to say, but reason it didn’t work is because I forgot to remove the line

if(IsPostBack) GridView.DataSourceID='';  

Sorry for taking your time and thanx for helping me

Answer 1

When you post back, you’ll have to rebind the data to the gridview.

You may also need to set the page number like:

GridView1.CurrentPageIndex = e.NewPageIndex;
