gridview_paging messing up

Question

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

Try assigning the datasource in NeedDataSource event.

Cheers.

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

Only if it isn't already declared in markup or in, say, a Load event. Do you have ViewState disabled? If not, I don't think you'd need to re-databind unless your data source only contains the displayed records (and omits the ones on other pages).

You're right. I don't need to rebind the data. But now, it doesnt change the the page until I click the page number twice...

Try this code It will absoloutly work :

protected void GV_PageIndexChanging(object sender, GridViewPageEventArgs e) { GV.PageIndex = e.NewPageIndex; BindGrid(); } public override void BindGrid() { query = new CommonQueries(); GV.DataSource = query.getAllBooks(); GV.DataBind(); }

the problem with your code is that you did'nt reassign the data source to your gridview !
