Hi Everyone.
I have form that have data source link to Sql Server Database.
When drag and drop the table with the data type=UltaGrid to the form, I get this error "An error occurred while performing the drop: Object reference not set to an instance of an object". If I change the data type = DataGridView, then it's ok.
Would anyone please tell me how to solve this problem? I'd greatly appreciated it. Thanks
Hello Steve,
If you need any additional assistance don’t hesitate to ask.

If you are talking about new feature in the VS, where you can set it up so that dragging a Table or Query onto a form automatically associates it with a control, then please take a look at the attached video file. This is one of my tests with UltraGrid and UltraControl. I think that everything works properly.
Please let me know if you have any questions, or if you think that I misunderstand your scenario.
I`m not sure that I udnerstand your scenario and issue. Could you please explain us what do you mean with "drag and drop the table with the data type=UltaGrid to the form .... If I change the data type = DataGridView, then it's ok" . Are you talking about TableAdapters and XSD schema or EntityDataModel.
Please give us more informaiton. Let me know if you have any questions.
