Data Error: Unable to update the data value: column
posted

 So I have an UltraWinTree that only allows editing of the check boxes. When I check a box it seems to be ok but when I go to select another node after checking a box I get a message box that pops up that says:

Data Error: Unable to update the data value: column

I'm not even sure where to begin with this error.  I have no idea what is causing it.  I can usually go from node to node and select different nodes but as soon as I check a box and select a different node it makes this box appear.  Its hard to debug an error when I don't know where its breaking.

    Ok I'm not sure what I did but now I'm getting an exception instead of that dialogue box.  This dosen't look like its happening in my code and am not sure how to proceed.  Also this time its triggered when I check the box, not when I select another node.

    See the end of this message for details on invoking
    just-in-time (JIT) debugging instead of this dialog box.
