Bind ImageUrl to GrindButtonColumn of DetailTables instead of MasterTableView

[Mário]

Hello,

I have this code and it does what i say in the title, but to a MasterTableView.

ASPX

<telerik:RadSplitter runat="server" ID="RSDocumentosDespesa" Width="100%" Height="100%" BorderSize="2">

      <telerik:RadPane runat="Server" ID="LeftPaneDocDespesa" Scrolling="None">

          <telerik:RadSplitter runat="server" ID="rsDocDespesaDetail" Width="100%" Height="100%" Orientation="Horizontal">

              <telerik:RadPane runat="Server" ID="TopPaneDocDespesaDetail" Scrolling="Both" Height="30%">

                  <telerik:RadGrid runat="server" ID="rgDocumentos" ShowStatusBar="false" ShowFooter="false" AutoGenerateColumns="false" OnSelectedIndexChanged="rgDocumentos_SelectedIndexChanged" OnItemCommand="rgDocumentos_ItemCommand" OnItemDataBound="rgDocumentos_ItemDataBound"

                      AllowSorting="false" AllowMultiRowSelection="false" AllowPaging="false" OnItemCreated="rgDocumentos_OnItemCreated" OnNeedDataSource="rgDocumentos_NeedDataSource" OnPreRender="rgDocumentos_PreRender" OnColumnCreated="rgDocumentos_ColumnCreated">

                      <MasterTableView DataKeyNames="DDR_Tipo_Doc, DDR_Cod, DDR_Intervencao_Cirurgica, EST_Designacao">

                          <Columns>

                              <telerik:GridBoundColumn HeaderText="Nr Ordem" ItemStyle-HorizontalAlign="Center" HeaderStyle-HorizontalAlign="Center" DataField="DDD_Num_Ordem" />

                              <telerik:GridBoundColumn HeaderText="Nr Doc." ItemStyle-HorizontalAlign="Center" HeaderStyle-HorizontalAlign="Center" DataField="DDD_Num_Doc" />

                              <telerik:GridBoundColumn HeaderText="Data" DataFormatString="{0:dd/MM/yyyy}" ItemStyle-HorizontalAlign="Center" HeaderStyle-HorizontalAlign="Center" DataField="DDD_Data" />

                              <telerik:GridButtonColumn HeaderText="" HeaderStyle-Font-Bold="true" ItemStyle-HorizontalAlign="Center" HeaderStyle-HorizontalAlign="Center" ButtonType="ImageButton" ImageUrl="Images/Botao/cancel.gif" UniqueName="Imagem"></telerik:GridButtonColumn>

                              <telerik:GridBoundColumn HeaderText="Estado" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Left" DataField="EST_Designacao" UniqueName="Estado" />

                              <telerik:GridBoundColumn HeaderText="Tipo" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Left" DataField="Tipo_Doc_Desc" />

                              <telerik:GridBoundColumn HeaderText="Valor" DataFormatString="{0:F2}" ItemStyle-HorizontalAlign="Right" HeaderStyle-HorizontalAlign="Right" DataField="DDD_Valor" />

                              <telerik:GridBoundColumn HeaderText="Valor Reembolsar" DataFormatString="{0:F2}" ItemStyle-HorizontalAlign="Right" HeaderStyle-HorizontalAlign="Right" DataField="DDR_Valor_Reeembolso" />

                              <telerik:GridBoundColumn HeaderText="Valor Subsistema" DataFormatString="{0:F2}" ItemStyle-HorizontalAlign="Right" HeaderStyle-HorizontalAlign="Right" DataField="DDR_Valor_Ref_Subsistema" />
...

C#

protected void rgDocumentos_ItemDataBound(object sender, GridItemEventArgs e)
   {
       if (e.Item is GridDataItem)
       {
           GridDataItem item = (GridDataItem)e.Item;
           switch (item.GetDataKeyValue("EST_Designacao").ToString().ToLower())
           {
               case "para devolução":
                   item["Imagem"].Enabled = false;
                   item["Devolver"].Enabled = false;
                   (item["Imagem"].Controls[0] as ImageButton).ImageUrl = "Images/para_devolucao.gif";
                   break;
               case "análise concluída":
                   item["Imagem"].Enabled = false;
                   item["Processar"].Enabled = false;
                   (item["Imagem"].Controls[0] as ImageButton).ImageUrl = "Images/analise_concluida.gif";
                   break;
         ...

But now i want to do it in one DetailTable inside, and now in this ASPX:

                   <telerik:RadGrid ID="rgProcessos" runat="server" ShowStatusBar="true" ShowFooter="false" CssClass="RadGrid"
                        AutoGenerateColumns="false" AllowSorting="true" AllowMultiRowSelection="false"
                        AllowPaging="true" OnDetailTableDataBind="rgProcessos_DetailTableDataBind"
                        OnNeedDataSource="rgProcessos_NeedDataSource" OnItemCommand="rgProcessos_ItemCommand"
                        OnItemCreated="rgProcessos_ItemCreated" OnColumnCreated="rgProcessos_ColumnCreated"
                        AllowFilteringByColumn="true"
                        PageSize="100" OnPreRender="rgProcessos_PreRender">
                        <PagerStyle Mode="NextPrevAndNumeric" AlwaysVisible="true" Position="Bottom" PagerTextFormat="páginas: {4} | página {0} de {1}, registo {2} a {3} de {5}" />
                        <MasterTableView DataKeyNames="PRC_Cod, Alerta" Name="Processos">

                            <DetailTables>
                                <telerik:GridTableView DataKeyNames="ADI_Cod" Name="Aditamentos" Width="100%" ShowFooter="false" AllowFilteringByColumn="false" AllowPaging="false">
                                    <DetailTables>
                                        <telerik:GridTableView DataKeyNames="EST_Designacao" Name="Documentos" Width="100%" AllowFilteringByColumn="false" AllowPaging="false">
                                            <Columns>
                                                <telerik:GridBoundColumn HeaderText="Nr Ordem" ItemStyle-HorizontalAlign="Center" HeaderStyle-HorizontalAlign="Center" DataField="DDD_Num_Ordem" />
                                                <telerik:GridBoundColumn HeaderText="Nr Documento" ItemStyle-HorizontalAlign="Center" HeaderStyle-HorizontalAlign="Center" DataField="DDD_Num_Doc" />
                                                <telerik:GridBoundColumn HeaderText="Data" DataFormatString="{0:dd/MM/yyyy}" ItemStyle-HorizontalAlign="Center" HeaderStyle-HorizontalAlign="Center" DataField="DDD_Data" />
<%--                                                <telerik:GridButtonColumn HeaderText="" HeaderStyle-Font-Bold="true" ItemStyle-HorizontalAlign="Center" HeaderStyle-HorizontalAlign="Center" ButtonType="ImageButton" ImageUrl="Images/Botao/cancel.gif" UniqueName="Imagem"></telerik:GridButtonColumn>--%>
                                                <telerik:GridBoundColumn HeaderText="Estado" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Left" DataField="EST_Designacao" UniqueName="Estado" />

Can you please help me how to do it? It is doing the same thing but to the GridButtonColumn in the inner detail table instead of doing it to the GridButtonColumn in the MasterTableView.

Thanks,
Mário

Just an extra information: i used the same code to do it but it cant access item["Imagem"] table cell. It's the same code behind with the same UniqueName.

Thanks.

Hi Mário,

When you want to access a detail table item, you have to use its Name property to identify the particular GridTableView and access the columns inside that as shown below.

C#:

protected void rgDocumentos_ItemDataBound(object sender, GridItemEventArgs e)
{
 if (e.Item is GridDataItem && e.Item.OwnerTableView.Name == "Documentos")
 {
   GridDataItem dataItem = (GridDataItem)e.Item;
   //Condition
    {
     (dataItem["Imagem"].Controls[0] as ImageButton).ImageUrl = "Image/ImageName.gif";
    }
  }
}

Thanks,
Shinu
