Add control itemdatabound event

[René]

Hello group,

I'am trying to add a gridview to a radgrid detailtable from code behind. De radgrid is databound from the code behind with datatables. Now i want to add a gridview on the ItemDataBound event of the radgrid. I have the following snippet aspx:

<telerik:GridTableView Name="Sales" AutoGenerateColumns="false" Width="100%" DataKeyNames="DetailCode,DetailSubCode"
                                       ShowHeadersWhenNoRecords="false" HierarchyDefaultExpanded="true" HierarchyLoadMode="ServerOnDemand">
                                       <DetailTables>
                                           <telerik:GridTableView Name="Planning">
                                               <ItemTemplate>
                                               <asp:GridView ID="GridView1" runat="server">
                                                   </asp:GridView>
                                               </ItemTemplate>
                                           </telerik:GridTableView>
                                           <telerik:GridTableView AutoGenerateColumns="false" DataKeyNames="ProdHeaderDossierCode"

                                                       </NoRecordsTemplate>
                                                   </telerik:GridTableView>
                                               </DetailTables>
                                           </telerik:GridTableView>
                                       </DetailTables>

And the code for ItemDataBound:

    Protected Sub RgNav_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RgNav.ItemDataBound
        If e.Item.ItemType = GridItemType.Item Then
            If e.Item.OwnerTableView.Name = "Sales" Then
                Dim DetailCode As String = e.Item.Cells(2).Text
                Dim DetailSubCode As String = e.Item.Cells(3).Text
                For Each Table As GridTableView In e.Item.OwnerTableView.DetailTables
                    If Table.Name = "Planning" Then
                        Dim Gv As GridView = Table.FindControl("GridView1")
                        Gv.DataSource = "Something"
                        Table.Controls.Add(Gv)
                    End If
                Next
            End If
        End If

    End Sub

Any help is welcome.

Thanks in advance,

René

Hi,

I suppose you want to bind the GridView in the ItemDataBound event. Please check the code snippet.

C#:

Protected Sub RadGrid1_ItemDataBound(sender As Object, e As GridItemEventArgs)
    If TypeOf e.Item Is GridDataItem Then
        If e.Item.OwnerTableView.Name = "Planning" Then
            Dim ditem As GridDataItem = DirectCast(e.Item, GridDataItem)
            Dim Gv As GridView = DirectCast(ditem.FindControl("GridView1"), GridView)
            Gv.DataSourceID = "Something"
        End If
    End If
End Sub

Thanks,
Princy.

Hi Prince,

Thanks for the reply

I placed you're code in my ItemDataBound event and ajusted it a little bit. The problem is that my GridView witch is declared in the aspx file cannot be found. The object remains nothing.

Declaration of aspx gridview:

<telerik:RadGrid ID="RgNav" runat="server" CellSpacing="0" GridLines="None" Skin="Office2007"
                            AutoGenerateColumns="false" HierarchyLoadMode="ServerOnDemand">
                            <HeaderStyle Height="21" Wrap="false" />
                            <ItemStyle Height="21" />
                            <AlternatingItemStyle Height="21" />
                            <MasterTableView DataKeyNames="DossierCode" HierarchyDefaultExpanded="true" Name="Dossier"
                                ItemStyle-Wrap="false" HeaderStyle-Wrap="false" HierarchyLoadMode="ServerOnDemand">
                                <HeaderStyle Height="21" Wrap="false" />
                                <ItemStyle Height="21" />
                                <AlternatingItemStyle Height="21" />
                                <DetailTables>
                                    <telerik:GridTableView Name="Sales" AutoGenerateColumns="false" Width="100%" DataKeyNames="DetailCode,DetailSubCode"
                                        ShowHeadersWhenNoRecords="false" HierarchyDefaultExpanded="true" HierarchyLoadMode="ServerOnDemand">
                                        <DetailTables>
                                            <telerik:GridTableView Name="Planning">
                                                <ItemTemplate>
                                                <asp:GridView ID="GridView1" runat="server">
                                                    </asp:GridView>
                                                </ItemTemplate>
                                            </telerik:GridTableView>

My ajusted ItemDataBound code:

 If e.Item.ItemType = GridItemType.Item Then
            If e.Item.OwnerTableView.Name = "Sales" Then
                Dim DetailCode As String = e.Item.Cells(2).Text
                Dim DetailSubCode As String = e.Item.Cells(3).Text
                For Each Table As GridTableView In e.Item.OwnerTableView.DetailTables
                    If Table.Name = "Planning" Then
                        Dim ditem As GridDataItem = DirectCast(e.Item, GridDataItem)
                        Dim Gv As GridView = DirectCast(ditem.FindControl("GridView1"), GridView)
                        Gv.DataSource = GenerateGrid_v2("010", "000")
                    End If
                Next
            End If
        End If

Could you please help me with this?

Thanks in advance,

René

Hi,

Please try the following code snippet.

C#:

Protected Sub RadGrid1_ItemDataBound(sender As Object, e As GridItemEventArgs)
    If TypeOf e.Item Is GridDataItem Then
        If e.Item.OwnerTableView.Name = "Sales" Then
            Dim DetailCode As String = e.Item.Cells(2).Text
            Dim DetailSubCode As String = e.Item.Cells(3).Text
        End If
        If e.Item.OwnerTableView.Name = "Planning" Then
            Dim ditem As GridDataItem = DirectCast(e.Item, GridDataItem)
            Dim Gv As GridView = DirectCast(ditem.FindControl("GridView1"), GridView)
            Gv.DataSourceID = "your data source"

        End If
    End If
End Sub

Thanks,
Princy.
