Hi,

I will give an example:

I have 3 columns in the dataSource: A, B, C.

I wrote this:

void grdGrades_InitializeLayout(object sender, InitializeLayoutEventArgs e)
{
//// MERGED CELL FUNCTIONALITY RELATED ULTRAGRID SETTINGS
//// ------------------------------------------------------------------------
// Set the merged cell style to the OnlyWhenSorted.
e.Layout.Override.MergedCellStyle = MergedCellStyle.OnlyWhenSorted;
e.Layout.Override.MergedCellContentArea = MergedCellContentArea.VisibleRect;
e.Layout.Override.HeaderClickAction = HeaderClickAction.SortMulti;
// ------------------------------------------------------------------------

e.Layout.Bands[0].SortedColumns.Add("A", false);
e.Layout.Bands[0].SortedColumns.Add("B", false);
e.Layout.Bands[0].SortedColumns.Add("C", false);
}

So if I have this data:

row 1: aaa, bbb, ccc

row 2: aaa, bbb, c

row 3: a, bbb, cc

In the grid, it will be displayed like this:

I don't want to display column A, but I still want that columns B and C will be affected by it.

so I want that even when column A is hidden, the grid will look like this:

Please help me to find a solution.

Thanks,
Yael
