[Solved] problems retrieving selected item on combobox

[Ignacio Ortuzar]

Hi,

I'm having some problems using the radcombobox.

I'm loading the combobox with an ObjectDataSource and when I want to get the selectedItem, selectedValue or selectedIndex, they are always null, "" or -1.

I was reading that combobox cannot access data when you use on demand loading, but what's mean?

that it's the code:

<telerik:RadComboBox ID="rcb_leads" runat="server" Width="290px"
        DataValueField="IDLEAD" Filter="Contains" DataTextField="EMAIL"
        DataSourceID="ods_getLeads" Text="Search" AutoPostBack="True"
            onselectedindexchanged="rcb_leads_SelectedIndexChanged" >
        <HeaderTemplate>
            <table style="width: 275px" cellspacing="0" cellpadding="0">
                <tr>
                    <td style="width: 177px;">
                        Lead Name</td>
                    <td style="width: 60px;">
                        Email</td>
                </tr>
            </table>
        </HeaderTemplate>
        <ItemTemplate>
            <table style="width: 275px" cellspacing="0" cellpadding="0">
                <tr>
                    <td style="width: 177px;">
                        <%# Eval("FIRSTNAME") + " " + Eval("LASTNAME") %></td>
                    <td style="width: 60px;">
                        <%# Eval("EMAIL") %></td>
                </tr>
            </table>
        </ItemTemplate>
    </telerik:RadComboBox>

and the datasource:

 <asp:ObjectDataSource ID="ods_getLeads" runat="server"
        SelectMethod="GetLeadByUserId" TypeName="LeadSius.stuff.DataAccess">
        <SelectParameters>
            <asp:SessionParameter Name="userId" SessionField="_userId" Type="Int32" />
        </SelectParameters>
    </asp:ObjectDataSource>

What is wrong with that?

If you use LoadOnDemand with the RadComboBox you cannot access the SelectedItems and SelectedIndex on the server-side. For a further explanation of this you can read over this documentation article:

http://www.telerik.com/help/aspnet-ajax/load-on-demand-access-items-server-side.html

You can use the SelectedValue property I believe (the article mentions it as well) and perhaps that will help you in this scenario.
