An error occurred while performing the drop: Object reference not set to an instance of an object
posted

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,

    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.
