Question

Hey guys,
I have a GridView which is binded to SqlDataSource, everything works fine, just update does not works, i am calling stored procedure, and all parameters and its dataTypes are proper, actually none of the events work on that update button, i tried to change the CommandName to “Change” and created OnCommand Event, and wrote Response Message in the code. but nothing happens on the update button, cancel button works fine, and also delete works, there is just a problem with update, even if the procedure has some issue atleast event should raised, i even checked in Sql Profiler, but the update procedure never hits Sql Server 2008…

But when i remove SqlDataSource then everything works fine also the update command with same stored procedure.

Please help me out for this, i have stuck here badly

ALTER PROCEDURE [dbo].[sp_UpdateQuotes]

@PublishedDate DateTime
AS

UPDATE dbo.Quotes SET

WHERE Title = @Title  

If @Published = 1  
BEGIN  
    UPDATE dbo.Quotes SET Published = 0 WHERE Title <> @Title AND Published = 1  
END  

END

Hope this would give you clear idea about what is messing me for update

Answer 1

You have not passed the @Title parameter, which is your primary Key in your stored procedure and is used in the where Clause.

If you want to see that there is no Title Parameter in Update Parameters:

<UpdateParameters>
    <asp:Parameter Name="Quote" Type="String" />
    <asp:Parameter Name="QuoteLink" Type="String" />
    <asp:Parameter Name="Published" Type="Boolean" />
    <asp:Parameter Name="PublishedDate" Type="DateTime" />
</UpdateParameters>

If you add the Title Parameter, it will work:

    <asp:Parameter Name="Title" Type="String" />
