How to disable the contextmenu for specific row in WinForms GridGroupingControl?
Context menu
To display a context menu based on the cell value in WinForms GridGrouping Control, use the TableControl.MouseDown event. In this event, a specific cell value can be retrieved from the current record using the current cell style and setting the ContextMenu based on the cell value.
C#
//Event Subscription
this.gridGroupingControl1.TableControl.MouseDown += TableControl_MouseDown;
//Event Customization
private void TableControl_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
int rowIndex, colIndex;
this.gridGroupingControl1.TableControl.PointToRowCol(e.Location, out rowIndex, out colIndex);
//To get the current cell style.
GridTableCellStyleInfo style = this.gridGroupingControl1.TableControl.GetTableViewStyleInfo(rowIndex, colIndex);
//To get the record.
Record record = style.TableCellIdentity.DisplayElement.GetRecord();
if(record != null)
{
bool value;
string boolValue = record.GetValue("Boolean").ToString();
if (bool.TryParse(boolValue, out value) && value)
this.gridGroupingControl1.ContextMenu = null;
else if (this.gridGroupingControl1.ContextMenu == null)
this.gridGroupingControl1.ContextMenu = menu;
}
else
{
//To avoid the contextmenu for header row.
this.gridGroupingControl1.ContextMenu = null;
}
}
}
VB
'Event Subscription
AddHandler Me.gridGroupingControl1.TableControl.MouseDown, AddressOf TableControl_MouseDown
'Event Customization
Private Sub TableControl_MouseDown(ByVal sender As Object, ByVal e As MouseEventArgs)
If e.Button = MouseButtons.Right Then
Dim rowIndex, colIndex As Integer
Me.gridGroupingControl1.TableControl.PointToRowCol(e.Location, rowIndex, colIndex)
'To get the current cell style.
Dim style As GridTableCellStyleInfo = Me.gridGroupingControl1.TableControl.GetTableViewStyleInfo(rowIndex, colIndex)
'To get the record.
Dim record As Record = style.TableCellIdentity.DisplayElement.GetRecord()
If record IsNot Nothing Then
Dim value As Boolean
Dim boolValue As String = record.GetValue("Boolean").ToString()
If Boolean.TryParse(boolValue, value) AndAlso value Then
Me.gridGroupingControl1.ContextMenu = Nothing
ElseIf Me.gridGroupingControl1.ContextMenu Is Nothing Then
Me.gridGroupingControl1.ContextMenu = menu_Renamed
End If
Else
'To avoid the contextmenu for header row.
Me.gridGroupingControl1.ContextMenu = Nothing
End If
End If
End Sub
