The information in the gridview displays fine, but when I try to go to page 2 I get an error:

error when click on tab

Here are the error details:

More info:

Message      "The GridView 'gvPendingRepairBids' fired event PageIndexChanging which wasn't handled."      string


Assuming I handle the event as suggested...what would I put inside it?

Or do I leave the event empty?

With default GridView you don't have to handle PageIndexChanging unless I am missing something.
So make sure your GridView markup doesn't have any OnPageIndexChanging set.

Now if it's needed in your case...check this:

For some reason it thinks it is needed.


But yeah, I have it fixed now:


     protected void gvPendingRepairBids_PageIndexChanging(object sender, GridViewPageEventArgs e)
        {
            SetPendingRepairsGridData(e.NewPageIndex);            
        }

        private void SetPendingRepairsGridData(int pageindex)
        {
            int atid = AssetTask.AssetUnitID;
            int atsid = AssetTask.AssetUnitSID;

            using (MarketingDataContext dc2 = new MarketingDataContext())
            {
                this.gvPendingRepairBids.PageIndex = pageindex;
                _pendingRepairBids = dc2.Marketing_Plan_PendingRepairBids_Get(atid, atsid).ToList<Marketing_Plan_PendingRepairBids_GetResult>();
                this.gvPendingRepairBids.DataSource = _pendingRepairBids;
                this.gvPendingRepairBids.DataBind();
            }
        }

It is.

I don't know what other software developers are like, but it does not come as "easily" to me as to some others I have observed.  I know what things I've done and I know what is possible, but can never seem to get it to STICK in my brain.  Sigh.

So, I really appreciate a second pair of eyes.  : )
