Hi,

I have the following telerik grid:

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
                                    <ContentTemplate>
                                        <telerik:RadGrid ID="GrdDynamic" runat="server" AutoGenerateColumns="false"
                                    ShowFooter="True">
                                    <MasterTableView>
                                      <Columns>
                                      <telerik:GridBoundColumn AllowFiltering="false" HeaderText="MovieID" UniqueName="MovieID" HeaderStyle-Wrap="false"
                                        DataField="MoviePriority">
                                      </telerik:GridBoundColumn>
                                    <telerik:GridTemplateColumn AllowFiltering="false" D HeaderText="Channel Number" UniqueName="Channel Number" ItemStyle-HorizontalAlign="Center">

                                        </ItemTemplate>
                                    </telerik:GridTemplateColumn>
                                    <telerik:GridTemplateColumn AllowFiltering="false" HeaderText="Transponder ID" UniqueName="Transponder ID" ItemStyle-HorizontalAlign="Center">
                                        <ItemTemplate>
                                            <asp:TextBox ID="txtTransponderID" runat="server" Text='<%# Bind("TransponderID") %>'/>
                                        </ItemTemplate>
                                    </telerik:GridTemplateColumn>
                                    <telerik:GridTemplateColumn AllowFiltering="false" HeaderText="Network ID" UniqueName="Network ID" ItemStyle-HorizontalAlign="Center">
                                        <ItemTemplate>
                                            <asp:TextBox ID="txtNetworkID" runat="server" Text='<%# Bind("NetworkID") %>'/>
                                        </ItemTemplate>
                                    </telerik:GridTemplateColumn>

                                       </MasterTableView>
                                       <ClientSettings AllowColumnHide="true" ReorderColumnsOnClient="false">
                                <Selecting AllowRowSelect="true" />
                                <Resizing AllowColumnResize="true" AllowRowResize="true" />
                            </ClientSettings>
                            <FilterMenu EnableEmbeddedSkins="False">
                            </FilterMenu>
                                        </telerik:RadGrid>
                                        <asp:LinkButton ID="btnSaveNetwork" runat="server"
                                            CssClass="button-orange-100"
                                           onclick="btnSaveNetwork_Click">Save Network </asp:LinkButton>
                                        <asp:Label ID="lblNetworkMsg" runat="server" class="LabelText" CssClass="ErrorMsg"
                                            Font-Size="Small" Height="16px" Text="Project Network info saved Successfully!"
                                            Visible="False" Width="242px"></asp:Label>
                                    </ContentTemplate>
                                </asp:UpdatePanel>

And in a submit button click event,I am writting the following code:

protected void btnSaveNetwork_Click(object sender, EventArgs e)
   {
       int res = 0;
       NetworkInformation netin = new NetworkInformation();
       netin.ProjectId = ProjectID;
       netin.UserId = Convert.ToInt32(SessionHelper.UserId);
       foreach (GridDataItem gvr in GrdDynamic.Items)
       {
           netin.ProjectId = ProjectID;
           netin.UserId = Convert.ToInt32(SessionHelper.UserId);
           netin.MoviePriority = Convert.ToInt32(gvr["MovieID"].Text);
           netin.ChannelNumber = (gvr["Channel Number"].Text!="")? Convert.ToInt32(gvr["Channel Number"]) : 0;
           netin.ServiceId = (gvr["Service ID"].Text!="")?gvr["Service ID"].Text:null;
           netin.TransponderId= (gvr["Transponder ID"].Text!="")?gvr["Transponder ID"].Text:null;
           netin.NetworkId= (gvr["Network ID"].Text!="")?gvr["Network ID"].Text:null;
           res=UpdateNetworkInfo(netin);
       }
       if (res > 0)
       {
           lblNetworkMsg.Visible = true;
           Reset();
       }
   }

But, the problem is: I am gettting null for ChannelNumber,ServiceID,TransponderID,NetworkID,i.e.,not being able to access the values entered in those respective textboxes.
Where am I going wrong?Do I need to write the same code in diff event?or diff code in diff event? Please suggest.

I have done it:

protected void btnSaveNetwork_Click(object sender, EventArgs e)
    {
        int res = 0;
        NetworkInformation netin = new NetworkInformation();
        netin.ProjectId = ProjectID;
        netin.UserId = Convert.ToInt32(SessionHelper.UserId);
        foreach (GridDataItem gvr in GrdDynamic.Items)
        {
            //netin.ProjectId = ProjectID;
            //netin.UserId = Convert.ToInt32(SessionHelper.UserId);

            netin.MoviePriority = Convert.ToInt32(gvr["MovieID"].Text);
            System.Web.UI.WebControls.TextBox channelno = gvr["Channel Number"].FindControl("txtChannelNo") as System.Web.UI.WebControls.TextBox;
            netin.ChannelNumber = Convert.ToInt32(channelno.Text);
            //netin.ChannelNumber = (gvr["Channel Number"].Text!="")? Convert.ToInt32(gvr["Channel Number"]) : 0;
            System.Web.UI.WebControls.TextBox serviceid = gvr["Service ID"].FindControl("txtServiceID") as System.Web.UI.WebControls.TextBox;
            netin.ServiceId = serviceid.Text;
            //netin.ServiceId = (gvr["Service ID"].Text!="")?gvr["Service ID"].Text:null;
            System.Web.UI.WebControls.TextBox transponderid = gvr["Transponder ID"].FindControl("txtTransponderID") as System.Web.UI.WebControls.TextBox;
            netin.TransponderId = transponderid.Text;
            //netin.TransponderId= (gvr["Transponder ID"].Text!="")?gvr["Transponder ID"].Text:null;
            System.Web.UI.WebControls.TextBox networkid = gvr["Network ID"].FindControl("txtNetworkID") as System.Web.UI.WebControls.TextBox;
            netin.NetworkId = networkid.Text;
            //   netin.NetworkId= (gvr["Network ID"].Text!="")?gvr["Network ID"].Text:null;
            res = UpdateNetworkInfo(netin);
        }
        if (res > 0)
        {
            Session["ProjectMaster"] = null;
            lblNetworkMsg.Text = "Project Network info saved Successfully!";
            //lblNetworkMsg.Visible = true;
            Cancel();
            GrdDynamic.Visible = false;
            btnEditProjectNetwork.Enabled = false;
            btnSaveProject.Enabled = false;
            btnReset.Enabled = false;
            btnCancel.Enabled = false;

        }
    }

Hope this helps someone else.
