The code you've posted won't compile - you're missing an opening bracket.

Solution 1

The reason for that exception is because you are not correctly casting the DataField property.

You need

C#

((BoundField)datagrid.Columns[0]).DataField = "TestID";

or

C#

BoundField col1 = datagrid.Columns[0] as BoundField;
col1.DataField = "TestID";
