Can you show us what your RadComboBox declaration looks like?

[Leszek]

sorry for delay. I was on the trip.

 

 

 

<telerik:RadComboBox ID="RadCBProducts" Runat="server" AutoPostBack="true"
                    DataSourceID="LinqDSProducts" DataTextField="ProductName"
                    DataValueField="IdProduct" Skin="Sunset" EnableLoadOnDemand="false">
                </telerik:RadComboBox>

 

 

 

protected void Page_Load(object sender, EventArgs e)
   {
       LinqDSPrices.Where = "Idproduct==" + RadCBProducts.SelectedValue;// this value is ""
       RadGrid1.DataBind();
       RadGrid1.Rebind();
   }

thanks
Leszek

Hello Leszek,

Change your code to this:

RadCBProducts.DataBind();
LinqDSPrices.Where = "Idproduct==" + RadCBProducts.SelectedValue;// this value is ""
RadGrid1.DataBind();
RadGrid1.Rebind();

You need to bind the RadComboBox when accessing it in the Page_Load event because it has not be data bound yet. Thus, the reason why SelectedValue is blank.

I hope that helps.

it is working now.
Thanks.
