    Are there any of those Events?
    I need to change the value of a cell (Databound to BindingList with INotifyPropertyChanged) if the mouse enters a cell and reset the value if the mouse leaves the cell.
    How is this possible?

    Hi Sebastian,

    Thank you for writing.

    You can achieve the desired functionality by subscribing to the CellMouseMove event of RadGridView, where you can change the hovered cell appearance and reset the previously hovered cell appearance. Here is a sample:
    GridCellElement lastHoveredCell = null;
    void radGridView1_CellMouseMove(object sender, MouseEventArgs e)
        GridCellElement cell = radGridView1.ElementTree.GetElementAtPoint(e.Location) as GridCellElement;
        if (cell != null)
            if (lastHoveredCell != null)
                lastHoveredCell.ResetValue(LightVisualElement.BackColorProperty, Telerik.WinControls.ValueResetFlags.Local);
                lastHoveredCell.ResetValue(LightVisualElement.DrawFillProperty, Telerik.WinControls.ValueResetFlags.Local);
                lastHoveredCell.ResetValue(LightVisualElement.GradientStyleProperty, Telerik.WinControls.ValueResetFlags.Local);
            cell.DrawFill = true;
            cell.BackColor = Color.Red;
            cell.GradientStyle = Telerik.WinControls.GradientStyles.Solid;
            lastHoveredCell = cell;

    I hope that you find this information helpful. Should you have any other questions, do not hesitate to contact us.
