RadGrid Delete Error

[David]

Hi,

I'm working on a project which uses the RadGrid from the classic controls.

Basically, the scenario is this. When the user clicks on an edit button for a row of the RadGrid, the panel which contains the RadGird is made invisible, and another panel with an assortment of textboxes and comboboxes is made visible with details of that grid row item populating thos controls. There is also a delete button on that panel, which delete that item in the database when clicked.

The problem arises when the grid is reloaded after that delete. Following the delete button being clicked, the grid's panel is made visible again and the grid is rebound. If I then click on one of the edit buttons for a row in the grid, the following error is thrown:

Server Error in '/' Application.

Any help would be appreciated. Previous searches of this forum show others have had the same problem and not resolved it.

*** Solved ***  I moved the following from the main RadGrid declaration its MasterTableView declaration ...

                    AllowAutomaticUpdates="true"
                    AllowAutomaticInserts="true"
                    AllowAutomaticDeletes="true"
