How to attach a context menu to a cell in GridGrouping control

3 Jan 20201 minute to read

By handling TableControlCurrentCellControlGotFocus and assigning context menu to the cell’s control, we can attach context menu to a cell when the cell is in the edit mode.

  • C#
  • //Subscribes to the events.
    
    this.gridGroupingControl1.TableControlCurrentCellControlGotFocus +=new 
    
    Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlControlEventHandler(gridGroupingControl1_TableControlCurrentCellControlGotFocus);
    
    
    
    this.gridGroupingControl1.TableControlCurrentCellControlLostFocus +=new 
    
    Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlControlEventHandler(gridGroupingControl1_TableControlCurrentCellControlLostFocus);
    
    
    
    // Attaches a context menu when the cell is in edit mode.
    
    private void gridGroupingControl1_TableControlCurrentCellControlGotFocus(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlControlEventArgs e)
    
    {
    
    e.Inner.Control.ContextMenu = this.contextMenu1;
    
    }
    
    
    
    //Resets the context menu when the cell losses focus.
    
    private void gridGroupingControl1_TableControlCurrentCellControlLostFocus(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlControlEventArgs e)
    
    {
    
    e.Inner.Control.ContextMenu = null;
    
    }
