Telerik grid updates not working in batch editing - telerik-grid

Question

I'm using RadGrid in ASPX, .net 4.5. The data comes up and displays in my grid fine, but I cannot update, insert, or delete records. I have followed the sample version as closely as I can:
http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/batch-editing/defaultcs.aspx
When I try to modify data in the grid, then hit Save, the grid reloads and the data is unchanged. No errors, just no updates.
Originally I had the grid wrapped in ajax panel, but when these problems occurred, I removed it. That made not much difference; though when I was using ajax panel, often times clicking the Save icon did absolutely nothing. Or appeared to do nothing. So with that gone, the page/grid does normal postbacks EXCEPT that none of my event handlers are being called. Page_Load gets called, but nothing else (for example RadGrid1_BatchEditCommand, RadGrid1_ItemUpdated). It seems these should be getting called.
ASPX code:

Please help. Why are the data updates not occurring? Why are none of the telerik events/methods in the codebehind being called? Only Page_Load() is executing, none of the others.

Answer 1

For me this was down to trying to use OnItemUpdated instead of OnUpdateCommand.
The ItemDeleted, ItemUpdated and ItemInserted events of RadGrid only work in combination with a directly bound ADO type DataSource. I'm using my own DAL so these 3 events weren't firing.
So the fix was to hook up the events OnUpdateCommand and OnDeleteCommand instead. The event handler looks something like this.
protected void radGrid_UpdateCommand(object sender, GridCommandEventArgs e)
{
var gridDataItem = ((GridDataItem)e.Item);
var table = gridDataItem.OwnerTableView;
var keyValues = table.DataKeyValues[gridDataItem.ItemIndex];
// Get key value.
var id = keyValues["id"];
// Get other values
var foo = ((TextBox)gridDataItem["foo"].Controls[0]).Text;
var bar = ((TextBox)gridDataItem["bar"].Controls[0]).Text;
myDAL.Update(id, foo, bar);
}
