Hi, Telerik Team .
My issue is i want to call my method do something when i click one row in EditorControl of MulticolumnComboBox, but i can't use SelectedIndexChange because if Index not change then event does't catch.
I try override method OnMouseUp of MultiColumnComboGridBehavior but this event also catch if i click the scrollBar in EditorControl. You can help me ! anyway, one event that On click one row in editor and dose not run when i click ScrollBar .
Thanks for answers

Hi Thanh, 

Thank you for writing.

The easiest approach for this case is to subscribe to the MouseDown event of the EditorControl and check if the clicked object is GridCellElement:

void EditorControl_MouseDown(object sender, MouseEventArgs e)
       {
           GridCellElement cellElement = radMultiColumnComboBox1.EditorControl.ElementTree.GetElementAtPoint(e.Location) as GridCellElement;
           if (cellElement != null)
           {
               Console.WriteLine("You have clicked a cell");
           }
       }

I hope that the provided information addresses your question.

All the best,

Hi Thanh,

Thank you for writing back.

Here is how to remove the formatting of the current and the selected row and cell and set the colors back to the one from the ControlDefault theme:

void EditorControl_ViewCellFormatting(object sender, CellFormattingEventArgs e)
{
    if (e.Row.IsSelected || e.Row.IsCurrent)
    {
        e.CellElement.GradientStyle = GradientStyles.Solid;
        e.CellElement.BackColor = Color.White;
        e.CellElement.BorderColor = Color.FromArgb(209, 225, 245);
        e.CellElement.BorderWidth = 1;
        e.CellElement.BorderBottomColor = Color.FromArgb(209, 225, 245);
        e.CellElement.BorderBoxStyle = BorderBoxStyle.SingleBorder;
        e.CellElement.BorderGradientStyle = GradientStyles.Solid;
    }
    else
    {
        e.CellElement.ResetValue(LightVisualElement.GradientStyleProperty, ValueResetFlags.Local);
        e.CellElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);
        e.CellElement.ResetValue(LightVisualElement.BorderColorProperty, ValueResetFlags.Local);
        e.CellElement.ResetValue(LightVisualElement.BorderWidthProperty, ValueResetFlags.Local);
        e.CellElement.ResetValue(LightVisualElement.BorderBottomColorProperty, ValueResetFlags.Local);
        e.CellElement.ResetValue(LightVisualElement.BorderBoxStyleProperty, ValueResetFlags.Local);
        e.CellElement.ResetValue(LightVisualElement.BorderGradientStyleProperty, ValueResetFlags.Local);
    }
}

void EditorControl_RowFormatting(object sender, RowFormattingEventArgs e)
{
    if (e.RowElement.IsSelected || e.RowElement.IsCurrent)
    {
        e.RowElement.GradientStyle = GradientStyles.Solid;
        e.RowElement.BackColor = Color.White;
    }
    else
    {
        e.RowElement.ResetValue(LightVisualElement.GradientStyleProperty, ValueResetFlags.Local);
        e.RowElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);
    }
}
