i just need to group a Grid column which in fact is a check box column. It contains only checked/unchecked boxes, and i want to allow them to be grouped. Here is my part of the code. Btw, some time ago, i figured it out, but cant remember now :(
<telerik:GridBoundColumnDataField="ID"FilterControlAltText="Filter ID column"HeaderText="ID"ReadOnly="True"SortExpression="ID"UniqueName="ID"CurrentFilterFunction="EqualTo"AutoPostBackOnFilter="true"ShowFilterIcon="false"HeaderStyle-Width="30px"FilterControlWidth="30px"></telerik:GridBoundColumn>
In order for RadGrid to group the data it uses the values for a given field in the data source. However, the template column you are trying to group by does not seem to be bound to a data source field. It displays only CheckBoxes. In that case there are no values the grid can use to perform the grouping.
You can bind the checkbox column to a boolean field in the data source. This way the data can be grouped cased on the value for the field in the data source.
