We are currently creating output displaying 'Total' and 'Avg' information.
Is it possible to add a row above, spanning multiple columns similar to
this?:

| Widgets |
+----------------+
| Total | Avg |

Thanks
Bill

It is not supported directly, but I can think of faking it by inserting
another data row with subheaders into the data table. You can format in a
special way making it look differently from data items. You can use
PreRender event for formatting.

Thanks Eiliyahu, though I am not sure I understand.

When you said data row, did you mean add another datagridcontrol? If so how
do we get all the columns to align?

If not, maybe you can elaborate (any code would be helpful).

Also, would there be a way to do this utilizing the templatecolumn?

Thanks again.
Bill

Hi Bill,

Below, I've pasted in some code that should help you create headers that
span. It is a little finicky but can be done. See the code comments for
details.

Let us know if this helps?

Bill,

I mean adding another data row to the data table. When you bind the grid to
the table, the row should be rendered straight after the header.

Yes, template columns can be used. You can prepare HTML in ItemTemplate for
both subheader and normal data and, in ItemDataBound event, check on the
very first data row. If an item is the very first data row, populate HTML
for subheaders.
