So I have a GridView for Winforms control on a form that refreshes the dataset every 3 minutes. Randomly during the day my users are reporting that the entire GridView control turns white and there is a red X in the control. This is the entire GridView control's canvas. Very wierd. This is the error that the user's receive:
(There is a checkbox column in the Master template, this is not a hierarchical dataset. It is flat.)
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
