RadGrid SelectedValue Problem

[Keven]

Hello,

I have a radgrid with a itemcommand who check the selected value. It was working until I move the page inside a content page. Now, the selected value is always nothing. Is there something I must do for it to work in a content page.

Thanks !

Keven

Hello Keven,

Can you please elaborate a bit more on your scenario? Are you using RadAjax in your application?

All the best,

This is a part of my code behind for my content page. This page was working before and since I change it into a content page, the RadGridDemande.SelectedValue returns nothing.

Private Sub RadGridDemande_ItemCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGridDemande.ItemCommand
        If e.CommandName = "ConsultDemande" Then
            If RadGridDemande.SelectedValue <> Nothing Then
                Dim No_Demande As String
                No_Demande = RadGridDemande.SelectedValue.ToString
                Response.Redirect("FEN_DEMANDE.aspx?No_Demande=" & No_Demande)
            Else
                'Message d'erreur disant de sélectionner un élément dans le tableau
            End If
        Else
            If e.CommandName = "RetourAccueil" Then
                Response.Redirect("WebForm1.aspx")
            Else
                If e.CommandName = "QuitterDemande" Then
                    Response.Redirect("FEN_LOGIN.aspx")
                End If
            End If
        End If
    End Sub

Hello Keven,

Your code worked at my end. As an alternate method, you could also try the following approach and see whether it works for you. 

C#:

if (e.CommandName == "ConsultDemande")
       {
           GridDataItem item = (GridDataItem)RadGridDemande.SelectedItems[0];
           if (item.GetDataKeyValue("LastName").ToString() != null)
           {
               string No_Demande = null;
               No_Demande = item.GetDataKeyValue("LastName").ToString();
           }
       }

Thanks,
Princy.

Thanks Princy for your response.

It didn't work when I tried your code, so i've search trough my code and I found the error. I was calling a rebind of my grid in my page load and it was preventing my itemcommand code from working.

Thanks

Keven
