Capturing cell/button clicks in MultiColumnComboBox dropdown

[T]

Hi,

I have a PushButton in one column and regular data in other columns. I've set up 3 event handlers to capture the clicks on the buttons, but none of these fires. Why? 

• (multiColumnComboBox1.ListControl as GridListControl).Grid.CellButtonClicked += CellButtonClicked;
  
• (multiColumnComboBox1.ListBox as GridListBox).Grid.CellButtonClicked += CellButtonClicked;
  
• (multiColumnComboBox1.ListControl as GridListControl).Grid.PushButtonClick += CellPushButtonClicked;
  

Thanks!

Hi Tipal,

Thank you for the update.

To trigger the cell click event of MultiColumnComboBox, we would suggest you to raise the event manually on MouseUp event of the ListBox. Please refer the below code and modified sample:

Code[C#] 

//Event customization 

private void ListBox_MouseUp(object sender, MouseEventArgs e) 

{ 

GridControl gc = this.multiColumnComboBox1.ListBox.Grid; 

int rowIndex = 0, colIndex = 0; 

gc.PointToRowCol(e.Location, out rowIndex, out colIndex); 

//Raising CellClick event manually 

gc.RaiseCellClick(rowIndex, colIndex, e); 

} 

private void Grid_CellClick(object sender, GridCellClickEventArgs e) 

{ 

MessageBox.Show("Grid cell event clicked"); 

GridControl gc = this.multiColumnComboBox1.ListBox.Grid; 

GridStyleInfo style = gc[e.RowIndex, e.ColIndex]; 

if (style.CellType == GridCellTypeName.PushButton) 

{ 

//Code to customize 

} 

} 

 

 

The same has been modified in the below sample. Please refer it from below:
