Hello Gonzalo,

You can access the controls, nested in your FormTemplate this way:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item.IsInEditMode)
    {
        DropDownList IdGenero = e.Item.FindControl("IdGenero") as DropDownList;
        //...
    }
}

Hi Daniel...
not exactly what I need.
Retrieving the value of the dropdown list is inside the grid has to be in the event (selectindexchanged) from the list, since there is recharged the other list, but I can not find the control IdClasificacion which is also within the grid.
What I do, would be something like this.


Protected Sub IdGenero_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
// this would drop down list I want to recharge
        IdClasificacion.Items.Clear()
        IdClasificacion.Items.Add(New ListItem("Todos", "999"))
        Dim genero As DropDownList = CType(GridNotas.MasterTableView.FindControl("IdGenero"), DropDownList)
// which I need to recover from the grid.
        If IdGenero.SelectedValue <> "999" Then
            IdClasificacionDB.SelectCommand = "SELECT IdClasificacion, Descripcion FROM Clasificacion WHERE IdGenero=" & IdGenero.SelectedValue
            If IdGenero.SelectedValue <> "1" And IdGenero.SelectedValue <> "2" Then
                IdClasificacion.Enabled = False
            Else
                IdClasificacion.Enabled = True
            End If
        End If
    End Sub

Hello Gonzalo,

Thank you for the clarification. A possible approach can be to get the second DropDownList via the current control's NamingContainer.

Sample code:

Protected Sub IdGenero_SelectedIndexChanged(sender As Object, e As EventArgs)
    Dim IdGenero As DropDownList = DirectCast(sender, DropDownList)
    Dim IdClasificacion As DropDownList = DirectCast(IdGenero.NamingContainer.FindControl("IdClasificacion"), DropDownList)
    'do something
End Sub
