gridview_paging messing up

Question

Hi,

I have an asp.net C# web app. In it I have a gridview. The gridview gets search results from a database. Sometimes there are a lot of results, and so I wanted to use paging. Here's what I tried:

     protected void grdResults_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        grdResults.PageIndex = e.NewPageIndex;
        grdResults.DataBind();
    }

For some reason, when I click on a page number, it shows me the EmptyDataText(There are no records to display). What code would work? Please help.

Thank you

Answer 1

You need to reassign your datasource to grdResults before the call to DataBind().

Answer 2

EDIT: Remove these lines, they are not needed(maybe):

grdResults.PageIndex = e.NewPageIndex;
grdResults.DataBind();

The binding is dependent on your datasource, see here.

Hi,

Try assigning the datasource in NeedDataSource event.
