[Solved] Retrieve DataItem on UpdateCommand

[jorge]

Hi, im using the ObjectDataSource to bind Class Objects to the RadGrid.

Class

Public Function ObtenerCliente(ByVal CLI_ID As Integer) As Cliente
        Dim Cli As New Cliente
        Dim Dt As DataTable = ListarClientes(CLI_ID)
        If Not Dt.Rows.Count = 0 Then
            Mappear(Dt.Rows(0), Cli)
        End If
        Cli.telefono = ObtenerTelefonos(CLI_ID)
        Cli.domicilio = ObtenerDomicilios(CLI_ID)
        Return Cli
    End Function
    Public Function ObtenerClientes() As List(Of Cliente)
        Dim lst_Cliente As New List(Of Cliente)
        Dim Cli As New Cliente
        Dim Dt As DataTable = ListarClientes(0)
        For Each Row As DataRow In Dt.Rows
            lst_Cliente.Add(ObtenerCliente(CInt(Row("CLI_ID"))))
        Next
        Return lst_Cliente
    End Function

    <telerik:radgrid runat="server" id="ClienteListado" AllowPaging="True"
        AllowSorting="True" DataSourceID="ods_Cliente" GridLines="None" Skin="WebBlue"
        AutoGenerateColumns="False"  >
    <MasterTableView CellSpacing="-1" DataSourceID="ods_Cliente">
        <Columns>
            <telerik:GridBoundColumn DataField="CLI_ID" HeaderText="Cod" ReadOnly="true"></telerik:GridBoundColumn>

            <telerik:GridBoundColumn DataField="CLI_EMAIL" HeaderText="Email"></telerik:GridBoundColumn>
            <telerik:GridDropDownColumn DataField="CLI_CIVA_ID" HeaderText="IVA" DataSourceID="ods_Civa" ListTextField="CIVA_NOMBRE" ListValueField="CIVA_ID"></telerik:GridDropDownColumn>
            <telerik:GridEditCommandColumn HeaderText="Editar" EditText="Editar" CancelText="Cancelar" ></telerik:GridEditCommandColumn>
        </Columns>
    </MasterTableView>
    </telerik:radgrid>
<asp:ObjectDataSource ID="ods_Cliente" runat="server"
    SelectMethod="ListarClientes" TypeName="ClienteManager">
    <SelectParameters>
        <asp:Parameter DefaultValue="0" Name="ID" Type="Int32" />
    </SelectParameters>
</asp:ObjectDataSource>

What I want is to retrieve the Class Object Binded to the current GridViewRow when the 

ClienteListado.UpdateCommand is fired.

Any idea?

 

i ve tried this but didnt work

 

 

 

Protected Sub ClienteListado_UpdateCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles ClienteListado.UpdateCommand

   MsgBox(TryCast(e.Item.DataItem, Cliente).nombre)

End Sub

 

 

Regards.

Hello George,

e.Item.DataItem will retrieve the corresponding values only during data-binding similar to the MS DataGrid and GridView and so the DataItem object would be null after a post-back. Instead, you can try accessing the key value for the grid item and pass it to your collection to find desired item.  

Protected Sub RadGrid1_ItemCommand(source As Object, e As GridCommandEventArgs)
    If e.CommandName = "Update" Then
        Dim item As GridDataItem = DirectCast((DirectCast(e.CommandSource, Button)).NamingContainer, GridDataItem)
        Dim value As Object = item.GetDataKeyValue("DataKeyName")
    End If
End Sub

Hope this helps..
Princy.
