The GridView fired event PageIndexChanging which wasn’t handled

Posted by Jamsi in ASP.NET on October 22nd, 2008 | 31 responses

If you’ve set a gridviews AllowPaging attribute to “true”, you’ll notice the following error;

The GridView fired event PageIndexChanging which wasn’t handled

To setup paging with Gridviews, you also need to set the page index property to the new page that you wish to view. Funny enough, this is extremely easy to do. See below for a code example written in C#.

The ASPX page

<asp:GridView ID="gvList" runat="server" AutoGenerateColumns="true" AllowPaging="true" PageSize="10" OnPageIndexChanging="gvList_PageIndexChanging">

and the C# code

    protected void gvList_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        bindGrid();

        gvList.PageIndex = e.NewPageIndex;
        gvList.DataBind();
    }

In my case, after adding those codes, the same exception will not be triggered, but all the other pages will not be displayed except the very first page. It is a total blank after I clicking page 2 or 3, or 4, 5 ….

I have tried the code supplied, but my code does not recognise bindGrid() as being in the current context.

What am I missing?

Aparently that fix does not work for everyone.

I have been trying to make grid view paging work on 2 different computers. One with Vista and VWD 2008 and one with XP and visual studio 2008.

I get the unhandled event error when clicking on the page number if I dont put code in the handler. If I put the code in the handler, my gridview disapears from the web page.
