error trying to go to page 2

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

Here are the error details:

System.NullReferenceException was unhandled by user code
  Message=Object reference not set to an instance of an object.

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?

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. : )
