I have been trouble shooting an SQL update using a Grid View in ASP.Net.  I am at the point where I have created a simple table to verify that I can update the table using a stored procedure.   I am using VS 2010.
Create table Publisher
(PublisherID int Primary Key identity(1,1)
,PublisherName varchar(100))
go

insert into Publisher values ('Marvel')

go
Create proc PublisherSelect
@PublisherID int
as
Select PublisherID
     , PublisherName
from Publisher
go

Create proc PublisherUpdate
@PublisherID int
, @PublisherName varchar(100)
as
Update Publisher
set PublisherName = @PublisherName
where PublisherID = @PublisherID

Open in new window

I have verified that the stored procedure works on the sql server.

My data source is the following:
   
      <asp:SqlDataSource ID="SqlDataSource1" runat="server" 
        ConnectionString="<%$ ConnectionStrings:TimeCardString %>" 
        ProviderName="<%$ ConnectionStrings:TimeCardString.ProviderName %>" 
        SelectCommand="PublisherSelect" SelectCommandType="StoredProcedure" 
        UpdateCommand="PublisherUpdate" UpdateCommandType="StoredProcedure">
        <SelectParameters>
          <asp:ControlParameter ControlID="TextBox1" Name="PublisherID" 
            PropertyName="Text" Type="Int32" />
        </SelectParameters>
        <UpdateParameters>
          <asp:Parameter Name="PublisherID" Type="Int32" />
          <asp:Parameter Name="PublisherName" Type="String" />
        </UpdateParameters>
      </asp:SqlDataSource>

Open in new window

and my Grid is as follows:
      <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"  
        DataKeyNames="PublisherID" DataSourceID="SqlDataSource1">
        <Columns>
          <asp:CommandField ShowEditButton="True" />
          <asp:BoundField DataField="PublisherID" HeaderText="PublisherID" 
            SortExpression="PublisherID" InsertVisible="False" ReadOnly="True" />
          <asp:BoundField DataField="PublisherName" HeaderText="PublisherName" 
            SortExpression="PublisherName" />
        </Columns>
      </asp:GridView>

Open in new window


When I attempt to update the record, I get error converting data type varchar to int.   If I let the SQL wizard create the update then things work as they should.

Sammy:

thanks for the reply on this issue.  I kept digging in to the issue.  I attempted my coding example in a different environment with success, so I attempted on a clean Project in the failing environment.  That worked.  I noticed that I was getting a non-critical error with a file in the failing environment, so I am going to assume that they are related.
