When the Child table's record count is zero the Plus/Minus cell type of it's Parent table should be set as static to make it disappear. Please refer the below code snippet which illustrates this: C# 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"; } } } VB Protected Sub GridGroupingControl1_QueryCellStyleInfo(ByVal sender As Object, ByVal e As GridTableCellStyleInfoEventArgs) If e.TableCellIdentity.TableCellType = GridTableCellType.RecordPlusMinusCell Then Dim r As Record = CType(IIf(TypeOf e.TableCellIdentity.DisplayElement.ParentRecord Is Record, e.TableCellIdentity.DisplayElement.ParentRecord, Nothing), Record) If Not r Is Nothing AndAlso r.NestedTables.Count > 0 AndAlso r.NestedTables(0).ChildTable.FilteredChildNodeCount = 0 Then e.Style.CellType = "Static" End If End If End Sub Sample: http://help.syncfusion.com/support/samples/kb/Grid.Web/6.1.0.34/NoChildRec/Plusminus.zip |
