I get this error when a button is clicked on my datagrid. Does anyone know what causes this? This is my custom error logger but it basically displays everything from the exception. The odd thing is the 'menu.aspx' page does load and the app seems to work fine, but I'd still like to know why this error is being thrown and caught.
