Hi Joel,
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
