I have a class called RadSpinEditorWithValidation which inherits from GridSpinEditor.  It contains additional functionality like range checking, turning the background to a different color if the validation fails etc.  I have added the EditorRequired event handler as follows:

private void m_grd_NewDetectors_EditorRequired(object sender, EditorRequiredEventArgs e)
{
     if (e.EditorType == typeof(GridSpinEditor))
     {
          e.EditorType = typeof(RadSpinEditorWithValidation);
     }
}

How do I give the editor instance the min value and max value, among other things?  Here it looks like it auto-instantiates an instance from the type (Activator?) I have to be able to access the instance of the editor and feed it some values so it knows what to do.

Thanks,

Evan

Hello Evan,

Thank you for writing.

You should use the CellEditorInitialized event to change any properties of the corresponding editor. For example, you can set maximum and minimum values for the default spin editor like this:
void radGridView1_CellEditorInitialized(object sender, GridViewCellEventArgs e)
{
    if (e.ActiveEditor is GridSpinEditor)
    {
        GridSpinEditor editor = e.ActiveEditor as GridSpinEditor;
        editor.MaxValue = 100;
        editor.MinValue = 0;
    }
     
}

More information about this event can be found in the following article: Handling Editors' events.
 
Please let me know if there is something else I can help you with.
