Problem with updating grid rating

[C O]

The code is basicly from the demo example, however, update results in error: ...object reference not set to an instance of an object. any help is appreciated.

VB:

If e.CommandName = "UpdateRating" Then
                Dim item As GridEditableItem = TryCast(e.Item, GridEditableItem)
                Dim values As New Hashtable()
                item.ExtractValues(values)
                values("ChangeRequestID") = item.GetDataKeyValue("ChangeRequestID")
                values("Completed") = Int16.Parse(values("Completed"))
                values("Accepted") = Int16.Parse(values("Accepted"))
                values("Reviewed") = Int16.Parse(values("Reviewed"))

                For Each entry As DictionaryEntry In values
                    SqlDataSource1.UpdateParameters(entry.Key.ToString()).DefaultValue = entry.Value.ToString()
                Next
                SqlDataSource1.Update()
            End If

And the grid:

<telerik:RadGrid ID="RadGrid1" runat="server" GridLines="None" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" ShowStatusBar="True"
              AllowAutomaticInserts="True" AllowAutomaticUpdates="True" OnItemCommand="RadGrid1_ItemCommand" Height="900px" PageSize="25" Skin="Black" DataSourceID="SqlDataSource1">
            <PagerStyle Mode="Slider" />

            <MasterTableView CommandItemDisplay="Top" DataKeyNames="ChangeRequestID" AllowMultiColumnSorting="True" DataSourceID="SqlDataSource1" AllowFilteringByColumn="True">
                <Columns>
                    <telerik:GridButtonColumn ButtonType="ImageButton" ImageUrl="Images/Update.gif" CommandName="UpdateRating" UniqueName="UpdateColumn" HeaderText="Update" />
                    <telerik:GridEditCommandColumn ButtonType="ImageButton" EditImageUrl="Images/Edit.gif" HeaderText="Edit" />
                    <telerik:GridRatingColumn DataField="Accepted" UniqueName="Accepted" Precision="Item" ReadOnly="False" ItemCount="1" HeaderText="Accepted" AllowRatingInViewMode="true" />
                    <telerik:GridRatingColumn Datafield="Reviewed" UniqueName="Reviewed" Precision="Item" ReadOnly="False" ItemCount="1" HeaderText="Reviewed" AllowRatingInViewMode="true" />
                    <telerik:GridRatingColumn Datafield="Completed" UniqueName="Completed" Precision="Item" ReadOnly="False" ItemCount="1" HeaderText="Completed" AllowRatingInViewMode="true" />
                    <telerik:GridRatingColumn Datafield="Priority" UniqueName="Priority" Precision="Item" ReadOnly="false" ItemCount="5" HeaderText="Priority" AllowRatingInViewMode="false" />
                    <telerik:GridBoundColumn DataField="ChangeRequestID" UniqueName="ChangeRequestID" HeaderText="ID" Visible="false" />
                </Columns>
                <EditFormSettings EditFormType="Template">
                <EditColumn UniqueName="EditCommandColumn1" />
                    <FormTemplate>
....

And the datasource:

<asp:SqlDataSource ID="SqlDataSource1" DataSourceMode="DataSet" runat="server" ConnectionString="<%$ ConnectionStrings:hldbConnectionString %>"

              InsertCommand="INSERT INTO ChangeRequestTracker(Accepted, Completed, Reviewed, Priority) VALUES (0, 0, 0, @Priority)"

              SelectCommand="SELECT * FROM ChangeRequestTracker ORDER BY ChangeRequestID DESC"

              UpdateCommand="UPDATE ChangeRequestTracker SET Priority=@Priority, Accepted=@Accepted, Reviewed=@Reviewed, Completed=@Completed  WHERE ChangeRequestID = @ChangeRequestID">
              <UpdateParameters>
                  <asp:Parameter Name="ChangeRequestID"/>
                  <asp:Parameter Name="Priority"/>
                  <asp:Parameter Name="Accepted"/>
                  <asp:Parameter Name="Reviewed"/>
                  <asp:Parameter Name="Completed"/>
              </UpdateParameters>
              <InsertParameters>
                  <asp:Parameter Name="Priority"/>
                  <asp:Parameter Name="Accepted"/>
                  <asp:Parameter Name="Reviewed"/>
                  <asp:Parameter Name="Completed"/>
              </InsertParameters>
          </asp:SqlDataSource>

Hello C O,

From the provided information I assume that for some reason the "Completed" new value is not extracted. Does the error occur when the grid item is in edit mode or does it persist if auto-generated edit forms are used instead of templated?

Sincerely yours,

I modified the grid to use auto generated forms and the same error appears for Insert, Update, and the rating update.
