GridView RowUpdating can not find edited information

I have the following TemplateField in my GridView:

             <asp:TemplateField HeaderText="Send Email?" SortExpression="SendEmail">
                    <EditItemTemplate>
                        <asp:CheckBox ID="cbEditSendEmail" runat="server" Checked='<%# Bind("SendEmail") %>' />
                    </EditItemTemplate>
                    <ItemTemplate>
                        <asp:CheckBox ID="cbSendEmail" runat="server" Checked='<%# Bind("SendEmail") %>' Enabled="false" />
                    </ItemTemplate>
                </asp:TemplateField>

I am trying to use the RowUpdating event to pass update parameters to a ObjectDataSource as follows:

    protected void gvAdminRights_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        CheckBox cb = ((CheckBox)(gvAdminRights.Rows[e.RowIndex].FindControl("cbEditSendEmail")));
        odsAdminRights.UpdateParameters["SendEmail"].DefaultValue = cb.Checked.ToString();
    }

The code finds the CheckBox. However, it does not return the updated Checked state. I always get the previous Checked state. So if the CheckBox was checked before I went to edit mode and unchecked it, I am still getting true for cb.Checked.

What am I doing wrong here?

Thanks for the response. Disabling the viewstate of the checkbox didn't fix the problem. This has been driving me nuts. I am sure others are having the same problem. I have spent 2 days on this and haven't been able to come up with a solution.

What do you think is the problem here?

I am binding the gridview to an ObjectDataSource as follows:

        <asp:ObjectDataSource ID="odsAdminRights" runat="server" DeleteMethod="DeleteAdmins"
            SelectMethod="GetAdmins" TypeName="AdminRightsBLL" UpdateMethod="UpdateAdmins"
            OnUpdating="odsAdminRights_Updating">
            <SelectParameters>
                <asp:QueryStringParameter Name="ModuleId" QueryStringField="mod" Type="Int32" />
                <asp:ControlParameter ControlID="dropAdminRightsCriteria" Name="EnvironmentID" PropertyName="SelectedValue"
                    Type="Int32" />
            </SelectParameters>
            <DeleteParameters>
                <asp:Parameter Name="userID" Type="Int32" />
                <asp:Parameter Name="moduleId" Type="Int32" />
                <asp:Parameter Name="environmentId" Type="Int32" />
            </DeleteParameters>
            <UpdateParameters>
                <asp:Parameter Name="UserId" Type="Int16" />
                <asp:Parameter Name="ModuleId" Type="Int16" />
                <asp:Parameter Name="EnvironmentID" Type="Byte" />
                <asp:Parameter Name="SendEmail" Type="Boolean" />
                <asp:Parameter Name="AssignRequest" Type="Boolean" />
            </UpdateParameters>
        </asp:ObjectDataSource>

and the UpdateAdmins in my BLL is as follows:

    public static bool UpdateAdmins(short UserId, short ModuleId, byte EnvironmentID, bool SendEmail, bool AssignRequest)
    {
        int rowsAffected = 0;

        rowsAffected = QuerysAdapter.UpdateAdmin(UserId, ModuleId, EnvironmentID, SendEmail, AssignRequest);

        return rowsAffected == 1;
    }

Have you tried the "RowUpdated" instead? That should catch the changes.

tried that.

I get the following: CS0117: 'System.Web.UI.WebControls.GridViewUpdatedEventArgs' does not contain a definition for 'RowIndex'

I don't know how to access the RowIndex.

I am going nuts..... am I the only one with this kind of problem?

could please show us all of your codebehind file? How you bind your GV, in pageload, when you bind your GV, you should put them into
if not page.ispostback then
    bindGv()
end if
condition.

I feel really stupid now!!

all this time, I had the following:
    protected void Page_Load(object sender, EventArgs e)
    {
            gvAdminRights.DataBind();
    }

while I should have had
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            gvAdminRights.DataBind();
    }

Thank you lijunguo for pointing this out. I feel much better... LOL

You're welcome. Glad to hear it's solved. Sometimes I also forget something or put the wrong logic, spend some time to fix it when it should not have happened at all.
