How fill label inside TemplateColumn of Telerik RadGrid in code behind

[Zakhaliya Ivarnovich]

Here is my RadGrid aspx :   

     

<telerik:RadGrid ID="grd_transactions" runat="server" GroupPanelPosition="Top" AutoGenerateColumns="False">
            <GroupingSettings CollapseAllTooltip="Collapse all groups"></GroupingSettings>
            <MasterTableView>
                <Columns>
                    <telerik:GridTemplateColumn FilterControlAltText="Filter TemplateColumn_Type column" HeaderText="Type" UniqueName="TemplateColumn_Type">
                        <HeaderStyle Font-Bold="True" Font-Size="Medium" Width="100px" HorizontalAlign="Center" VerticalAlign="Middle" />
                        <ItemTemplate>
                            <asp:Label ID="lbl_Type" runat="server" Text="lbl_Type"></asp:Label>
                        </ItemTemplate>
                    </telerik:GridTemplateColumn>
                    <telerik:GridTemplateColumn FilterControlAltText="Filter TemplateColumn_Date_Time_UTC_GMT column" HeaderText="Date & Time (UTC/GMT)" UniqueName="TemplateColumn_Date_Time_UTC_GMT">
                        <HeaderStyle Font-Bold="True" Font-Size="Medium" Width="200px" HorizontalAlign="Center" VerticalAlign="Middle" />
                        <ItemTemplate>
                            <asp:Label ID="lbl_Date_Time_UTC_GMT" runat="server" Text="lbl_Date_Time_UTC_GMT"></asp:Label>
                        </ItemTemplate>
                    </telerik:GridTemplateColumn>
                    <telerik:GridTemplateColumn FilterControlAltText="Filter TemplateColumn_BTC_Investment_Address column" HeaderText="BTC Investment Address" UniqueName="TemplateColumn_BTC_Investment_Address">
                        <HeaderStyle Font-Bold="True" Font-Size="Medium" Width="600px" HorizontalAlign="Center" VerticalAlign="Middle" />
                        <ItemTemplate>
                            <asp:Label ID="lbl_BTC_Investment_Address" runat="server" Text="lbl_BTC_Investment_Address"></asp:Label>
                        </ItemTemplate>
                    </telerik:GridTemplateColumn>
                    <telerik:GridTemplateColumn FilterControlAltText="Filter TemplateColumn_Deposit_Amount column" HeaderText="Deposit Amount" UniqueName="TemplateColumn_Deposit_Amount">
                        <HeaderStyle Font-Bold="True" Font-Size="Medium" Width="150px" HorizontalAlign="Center" VerticalAlign="Middle" />
                        <ItemTemplate>
                            <asp:Label ID="lbl_Deposit_Amount" runat="server" Text="lbl_Deposit_Amount"></asp:Label>
                        </ItemTemplate>
                    </telerik:GridTemplateColumn>
                    <telerik:GridTemplateColumn FilterControlAltText="Filter TemplateColumn_Payout_Amount column" HeaderText="Payout Amount" UniqueName="TemplateColumn_Payout_Amount">
                        <HeaderStyle Font-Bold="True" Font-Size="Medium" Width="150px" HorizontalAlign="Center" VerticalAlign="Middle" />
                        <ItemTemplate>
                            <asp:Label ID="lbl_Payout_Amount" runat="server" Text="lbl_Payout_Amount"></asp:Label>
                        </ItemTemplate>
                    </telerik:GridTemplateColumn>
                    <telerik:GridTemplateColumn FilterControlAltText="Filter TemplateColumn_Status column" HeaderText="Status" UniqueName="TemplateColumn_Status">
                        <HeaderStyle Font-Bold="True" Font-Size="Medium" Width="150px" HorizontalAlign="Center" VerticalAlign="Middle" />
                        <ItemTemplate>
                            <asp:Label ID="lbl_Status" runat="server" Text="lbl_Status"></asp:Label>
                        </ItemTemplate>
                    </telerik:GridTemplateColumn>
                </Columns>
            </MasterTableView>
        </telerik:RadGrid>

Now in code behind i want to fill those labels inside TemplateColumns like this :  
 

DataTable table = new DataTable();
table.Columns.Add("Type", typeof(string));
table.Columns.Add("Date & Time (UTC/GMT)", typeof(string));
table.Columns.Add("BTC Investment Address", typeof(string));
table.Columns.Add("Deposit Amount", typeof(string));
table.Columns.Add("Payout Amount", typeof(string));
table.Columns.Add("Status", typeof(string));
table.Rows.Add("1", "2", "3", "4" ,"5", "6");
table.Rows.Add("1", "2", "3", "4", "5", "6");
table.Rows.Add("1", "2", "3", "4", "5", "6");
table.Rows.Add("1", "2", "3", "4", "5", "6");
table.Rows.Add("1", "2", "3", "4", "5", "6");
grd_transactions.DataSource = table;
grd_transactions.DataBind();

Here is the wrong output.

How can i access those labels & fill them?

Hello Zakhaliya,

The text for the labels is set statically and the and if you need them to be bound to the data source, you would need to use the Eval or Bind expressions instead: 

• https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/appearance-and-styling/customizing-with-gridtemplatecolumn;

<ItemTemplate>
    <asp:Label ID="lbl_Type" runat="server" Text='<%# Eval("ShipCountry") %>'></asp:Label>
</ItemTemplate>

Or

<ItemTemplate>
    <asp:Label ID="lbl_Type" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "ShipCountry") %>'></asp:Label>
</ItemTemplate>

Regarding the data binding, we strongly recommend using the AdvancedDataBinding, i.e. using the NeedDataSource event instead of the .DataBind() method:

• https://www.telerik.com/support/kb/aspnet-ajax/grid/details/how-to-bind-radgrid-properly-on-server-side;
• https://demos.telerik.com/aspnet-ajax/grid/examples/data-binding/simple-vs-advanced/defaultcs.aspx;
