I'm using Visual Studio 2010 and .NET Framework 4.0

I've created an ASPX page containing a databound WebGrid and a WebInput control.  I have configured the grid to use the WebInput control for editing the cells in a particular column.

When I display the page, the grid works fine.  When I attempt to edit a cell in the column for which I've specified that the WebInput control should be used, I can select the cell, but when I attempt to enter any value in the WebInput, I immediately receive a javascript error (see attached screenshot).

If I configure the grid to use only the built-in textbox for editing, everything works fine.

I have tried various settings on the grid and webinput, but I can't seem to get past this error.  Furthermore, when I attempt to use the WebInput.NET Designer, I receive the error "Exception has been thrown by the target of an invocation." (see attached screenshot).

It's imperative that I use the WebInput control as I need to mask and filter the data entered into the grid by the user, and inline editing is a requirement.

I submitted a support request a few days ago, however it's still in "Waiting for Assignment" status.

I'm getting rather frustrated by the lack of response to my support request as well as the failure of the WebInput to function properly.

Can anybody tell me what I'm missing here or provide a fix or workaround?
