I'm bucketing a dataset according to three levels: level1, level2, level3. Sometimes level 3 is empty. Is there a way to roll up the items into the level 2 header and not show the empty level 3 header? I'm rephrasing a previous question because I'm thinking maybe it wasn't understood.

Hi,

To disable the Expand of column header where no records found in child table,you need to write below code in the event of QueryCellStyleInfo.


protected void GridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
{
if (e.TableCellIdentity.TableCellType == GridTableCellType.RecordPlusMinusCell)
{
Record r = e.TableCellIdentity.DisplayElement.ParentRecord as Record;
if (r != null && r.NestedTables.Count > 0 && r.NestedTables[0].ChildTable.FilteredChildNodeCount == 0)
{
e.Style.CellType = "Static";
}
}
}

please refer the below KB article

Best regards,
Johnson
