Hi

I have a masterdetail grid with two group by expressions to group the data at 2 levels. All works well. However in the footer text of the row, I would like the value of the group by expression to be shown.

So at present it is something like this

This is my top header
	This is my second header
		RowData1	20	30	15	22
		RowData2	12	11	9	15
		RowData3	11	52	11	23
			43	93	35	60
		RowData4	156	11	22	347
			156	11	22	347
			199	104	57	407

What I want is this

This is my top header
	This is my second header
		RowData1	20	30	15	22
		RowData2	12	11	9	15
		RowData3	11	52	11	23
	This is my second header		43	93	35	60
		RowData4	156	11	22	347
	This is my second header		156	11	22	347
This is my top header			199	104	57	407

And then when it collapses I would ideally like

This is my top header
	This is my second header	43	93	35	60
	This is my second header2	156	11	22	347
This is my top header		199	104	57	407

Help very much appreciated

Thanks

Hi

This doesnt solve my problem I am afraid as that the header text is static.

I need it to be dynamic with the value of the grouping. So I need the headertext (or group footer text) to be the value of the grouping and that the totals are under each of the columns as you see in the group footer

I attach some example code and a screen shot. In the screen shot you will see some "balloons" and those balloons contain the text that I want in the group footer. Ideally I would like it in the group header so that when the grid is collapsed I only have 1 row per grouping with the values but I understand the group footer aggregation functionality is not available in the groupheader.

The values are taken from the grouping value. The reason I need these are so that when the group is collapsed, I can see the totals and the grouping they relate to. If I could then hide the header when collapsing that would be even better
