Forms Data Controls :: Bind Data From DataSet (DataTable) To A Selectrow DropDownList In GridView?
Nov 19, 2010I have a Gridview and two link button in that GridView , one link button click is to add edit row ( Edit ), one link button click is to select row ( Select ). I have a dropdownlist inside row which selected when i click link button Select in the gridview edit template, as of my business logic i need to show the dropdownlist only when the user clicks Edit button and when the user clicks Select button . That mean when the user clicks Select button then they clicks Edit button on the gridvview i should allow him to edit the dropdownlist (showing the value to the user through a label).
ASPX CODE
[Code].... C#
When I click Select link button , then I click Edit link button . They have errors : Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" I don't know what error?. How to fix it

Forms Data Controls :: ObjectDataScource Not Working / ObjectDataSource1' Could Not Find A Non-generic Method?
Jan 8, 2010Most likely the later, I think. In my page I have a GridView, DatailsView, and the ODS. None of my commands work. For the Udate command I get a an error "ObjectDataSource 'ObjectDataSource1' could not find a non-generic method 'UpdateVirtual' that has parameters: name, notes, active, original_ident." For the Delete command I get "ObjectDataSource 'ObjectDataSource1' could not find a non-generic method 'DeleteVirtual' that has parameters: ident, original_ident." Yet the Insert command in the DetailsView works fine. Originally I've copied a file that performs virtually identical task, the only difference is a different database and the Select command. I had the Delete command working for for while but that one too broke. Can someone point out what I'm doing wring?
