[Solved] AllowAutomaticDeletes not deleting

[Duncan Evans]

Morning,

I have a problem with the delete command on my radgrid. I was getting the error that there was null values and i needed to change "ConflictDetection" to OverwriteChanges". However this problem seems to been fixed by changing many of the Eval() bindings to Bind().

I have some binding in the grid that happens programmatically also.

Now when i hit delete, it attempts to process the command and refreshes the grid and the items remains. No error, it just does not delete the row from the SQLDataSource.

Any help would be greatly appreciated.

Hello Duncan,

I'm assuming the problem is with your delete statement. I don't see the reason for checking every column, outside of the ID column to perform a delete operation. So try removing those columns from the delete statement and see if that works.

Otherwise, I would handling the ItemDeleted event of the RadGrid and setting up a breakpoint in there to see what's going.

I hope that helps.

[Duncan Evans]

That did the trick. The DELETE statement was auto-generated by the SqlDataSource... Modifying it to the following works perfect now:

    <asp:SqlDataSource ID="WriteUps_DataSource" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
        InsertCommand="INSERT INTO [WriteUps] ([DateAdded], [PtName], [Ins], [Campaign], [Outcome], [CCRep], [Source], [NumberCalled], [State]) VALUES (@DateAdded, @PtName, @Ins, @Campaign, @Outcome, @CCRep, @Source, @NumberCalled, @State)"
        SelectCommand="SELECT [ID], [DateAdded], [PtName], [Ins], [Campaign], [Outcome], [CCRep], [Source], [NumberCalled], [State] FROM [WriteUps]"
        DeleteCommand="DELETE FROM [WriteUps] WHERE [ID] = @original_ID"
        UpdateCommand="UPDATE [WriteUps] SET [DateAdded] = @DateAdded, [PtName] = @PtName, [Ins] = @Ins, [Campaign] = @Campaign, [Outcome] = @Outcome, [CCRep] = @CCRep, [Source] = @Source, [NumberCalled] = @NumberCalled, [State] = @State WHERE [ID] = @original_ID AND (([DateAdded] = @original_DateAdded) OR ([DateAdded] IS NULL AND @original_DateAdded IS NULL)) AND (([PtName] = @original_PtName) OR ([PtName] IS NULL AND @original_PtName IS NULL)) AND (([Ins] = @original_Ins) OR ([Ins] IS NULL AND @original_Ins IS NULL)) AND (([Campaign] = @original_Campaign) OR ([Campaign] IS NULL AND @original_Campaign IS NULL)) AND (([Outcome] = @original_Outcome) OR ([Outcome] IS NULL AND @original_Outcome IS NULL)) AND (([CCRep] = @original_CCRep) OR ([CCRep] IS NULL AND @original_CCRep IS NULL)) AND (([Source] = @original_Source) OR ([Source] IS NULL AND @original_Source IS NULL)) AND (([NumberCalled] = @original_NumberCalled) OR ([NumberCalled] IS NULL AND @original_NumberCalled IS NULL)) AND (([State] = @original_State) OR ([State] IS NULL AND @original_State IS NULL))"
        OldValuesParameterFormatString="original_{0}"
        ConflictDetection="CompareAllValues">
        <DeleteParameters>
            <asp:Parameter Name="original_ID" Type="Int32" />
        </DeleteParameters>
...

Thanks much!
