What is the error message you got ?

Is it a buttoncolumn or templatecolumn ?

Change the autoeventwirup to false and try.

If not RE me.

To delete row use javascript

        function CellButtonClick(gridId, cellId) 
        {
            var Row = igtbl_getRowById(cellId);
            Row.deleteRow();
        }

In <ClientSideEvents ................../>

Add this to call the javascript

ClickCellButtonHandler="CellButtonClick"


After row deleted

<itgbl:UltraWebGrid OnDeleteRow = "" <-- Event Fires.

Here you handle what you want
