Loadondemand and problem in obtaining selected value

[Canis Lupus]

Hello,

I am using loadondemand for a radcombobox control as follow:

<telerik:RadComboBox ID="DDL_district" Runat="server"

DataSourceID="DS_district" DataTextField="fullAddress  
DataValueField="recID" Width="100%" AppendDataBoundItems="True"

                            EnableAutomaticLoadOnDemand="True" Filter="Contains"

                            MinFilterLength="3" ShowMoreResultsBox="True"

                            EnableVirtualScrolling="True" ItemsPerRequest="10"

                            LoadingMessage="Loading...."

                            EmptyMessage="No such district in the database."

                            MaxHeight="250px">

                            <Items>

                                <telerik:RadComboBoxItem runat="server" Selected="True"

                                    Text="some text"

                                    Value="0" />

                            </Items>

                          </telerik:RadComboBox>

when I try to obtain the selected value in run-time I always get "0" value even if I select an item from database.
I use following code to get districtID value

Dim districtID As String = DDL_district.SelectedValue

Am I missing something?

You've put for the value:

Value="0"

Try to set the value to a meaningful number, or string.  Or you could use the SelectedItem property instead.

Hi Mehmet,

Sorry for my late response.

In order to get the selected items value in server-side first you should perform a postback.
I've prepared a small example for you showing how to get the value of the selected item from the combobox.
Also you could check this article here for more information.
I hope this will help.
