Hi, I''m trying to change the group captiontext to show a couple other column values on that line. so far all i could do was concatenate the fields in the sql and group by that new column. I''m wondering if there is a better way? tia

Colin, you can override the contents of any cell in the grouping grid by handling the GridGroupingControl.QueryCellStyleInfo event. Check for e.Style.TableCellIdentity.TableCellType == GridTableCellType.CaptionCell and then assign the text you want to display in the cell as e.Style.Text. Stefan

also, once i''m in the QueryCellStyleInfo event, can you see what the grouping field is?

i guess i can use e.style.text to get the recordcount right next to "items". is there another way?

The style identity object has a DisplayElement property (which should be a CaptionRow element in your case). You can get the group that is displayed in that caption with the .ParentGroup property. This Group then offers a couple of methods, e.g. GetFilteredRecordCount() will return the number of records in that group. CategoryKeys returns the keys for this category and GetChildCount() returns "Items count" property. In the GroupCustomers sample you can hover the mouse over the cells and a tooltip will display the DisplayElement kind for various cells and some more information found in the style identity objects for cells.

Here is a little sample showing some ways to do most of the things you mentioned. GGC_QueryCellStyleInfo_3768.zip
