So I’m been pounding on this problem all day. I’ve got a LinqDataSource that points to my model and a GridView that consumes it. When I attempt to do an update on the GridView, it does not update the underlying data source. I thought it might have to do with the LinqDataSource, so I added a SqlDataSource and the same thing happens. The aspx is as follows (the code-behind page is empty):

  <asp:SqlDataSource ID='SqlDataSource1' runat='server'        ConnectionString='Data Source=devsql32;Initial Catalog=Steam;Persist Security Info=True;'        ProviderName='System.Data.SqlClient'        SelectCommand='SELECT [LangID], [Code], [Name] FROM [Languages]' UpdateCommand='UPDATE [Languages] SET [Code]=@Code WHERE [LangID]=@LangId'>   </asp:SqlDataSource>   <asp:GridView ID='_languageGridView' runat='server' AllowPaging='True'        AllowSorting='True' AutoGenerateColumns='False' DataKeyNames='LangId'        DataSourceID='SqlDataSource1'>       <Columns>           <asp:CommandField ShowDeleteButton='True' ShowEditButton='True' />           <asp:BoundField DataField='LangId' HeaderText='Id' ReadOnly='True' />           <asp:BoundField DataField='Code' HeaderText='Code' />           <asp:BoundField DataField='Name' HeaderText='Name' />       </Columns>   </asp:GridView>   <asp:LinqDataSource ID='_languageDataSource' ContextTypeName='GeneseeSurvey.SteamDatabaseDataContext' runat='server' TableName='Languages' EnableInsert='True' EnableUpdate='true' EnableDelete='true'>  </asp:LinqDataSource>

What in the world am I missing here? This problem is driving me insane.

  1. It turns out that we had a DataBind() call in the Page_Load of the master page of the aspx file that was probably causing the state of the GridView to get tossed out on every page load.

    As a note – update parameters for a LINQ query are not required unless you want to set them some non-null default.
