    For the Row indicator column on the very left. I would like to change the background color based on an entry on one of the row values. 

    I have checked out this article -

    But do not know the type in order to get the row indicator cell/column

    Hello, Terry, 

    In order to customize the grid cells, it it suitable to use the CellFormatting/ViewCellFormatting event as you have already found out. You can find below a sample code snippet demonstrating how to color the indicator cells:

    private void radGridView1_ViewCellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)
        GridRowHeaderCellElement rowHeader = e.CellElement as GridRowHeaderCellElement;
        if (rowHeader != null)
            e.CellElement.DrawFill = true;
            e.CellElement.BackColor = Color.Red;
            e.CellElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid;
            e.CellElement.ResetValue(LightVisualElement.DrawFillProperty, ValueResetFlags.Local);
            e.CellElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);
            e.CellElement.ResetValue(LightVisualElement.GradientStyleProperty, ValueResetFlags.Local);

    I would recommend you to use the RadControlSpyForm tool which is quite useful for inspecting the elements. Thus, you can find very easily which elements to customize.

    I hope this information helps.
