I have wired up an Object DataSource control on the page to do the grunge work for me however when I try to Delete a record my target DeleteMethod does not get the parameters it requires. I have looked around on the help and it looks like the data is supposed to be extracted and available for me to use.

<asp:ObjectDataSource ID="DocLinkViewDataSource" runat="server" TypeName="DocumentsManager" 
        SelectMethod="getDocumentBranchLinkDS" 
        InsertMethod="CreateDocumentBranchLink" 
        UpdateMethod="UpdateDocumentBranchLink" 
        DeleteMethod="DeleteDocumentBranchLink">  
          
        .......  
 
        <DeleteParameters> 
            <asp:Parameter Name="BranchDatabase" Type="String" /> 
            <asp:Parameter Name="DocumentID" Type="String" /> 
            <asp:Parameter Name="BusinessType" Type="String" /> 
        </DeleteParameters> 
    </asp:ObjectDataSource> 

Public Sub DeleteDocumentBranchLink(ByVal BranchDatabase As String, _  
   ByVal DocumentID As StringByVal [BusinessType] As String

Hello Josh,

Indeed the three parameters you specified using the DeleteParameters collection of your ObjectDataSource instance should be passed as arguments to your DeleteMethod. Can you please debug your code to see whether they are processed as expected and ensure that the AllowAutomaticDeletes property of the grid is set to true?

You may also review the project from this code library thread for further reference.

Stephen,

I decided to change my stored procedure to only require the ID which is setup as a DataKeyName so it was available to me. If I remember correctly if I enabled the OldValuesParameterFormatString parameter on the datasource I was able to access these values.

Thanks
