Hi,
 
I have a rad combo box code given below.

 <telerik:RadComboBox
                    ID="RadComboBox_Agency" runat="server"
                    Height="190px" Width="200px"
                    MarkFirstMatch="true" EnableLoadOnDemand="true" HighlightTemplatedItems="true"
                    DataTextField="CompanyName" DropDownWidth="375" ItemRequestTimeout="500"
                    OnItemsRequested="RadComboBox_Agency_ItemsRequested"
                    Skin="Vista">
                    <HeaderTemplate>
                        <table style="width: 375px" cellspacing="0" cellpadding="0">
                            <tr>
                                <td style="width: 125px;">
                                    Name
                                </td>
                                <td style="width: 125px;">
                                    Phone
                                </td>
                                <td style="width: 125px;">
                                    Zip
                                </td>
                            </tr>
                        </table>
                    </HeaderTemplate>
                    <ItemTemplate>
                        <table style="width: 375px" class="comboTable" cellspacing="0" cellpadding="0">
                            <tr>
                                <td style="width: 125px;" class="comboItemCell">
                                    <div class="comboItem">
                                        <%# DataBinder.Eval(Container.DataItem, "CompanyName")%>
                                    </div>
                                </td>
                                <td style="width: 125px;" class="comboItemCell">
                                    <div class="comboItem">
                                        <%# DataBinder.Eval(Container.DataItem, "Phone")%>
                                    </div>
                                </td>
                                <td style="width: 125px;" class="comboItemCell">
                                    <div class="comboItem">
                                        <%# DataBinder.Eval(Container.DataItem, "PostalCode")%>
                                    </div>
                                </td>
                            </tr>
                        </table>
                    </ItemTemplate>
                </telerik:RadComboBox>

Hi Eva,

Set the DataValueField for the RadComboBox and access the SelectedValue in its SelectedIndexChanged event. Here is the code which I tried on my end.

ASPX:

    <telerik:RadComboBox ID="RadComboBox1" runat="server" AutoPostBack="true" AllowCustomText="true" DataTextField="ProductName"  DataValueField="SupplierID"  DataSourceID="SqlDataSource1" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged" OnItemDataBound="RadComboBox1_ItemDataBound" >
           <ItemTemplate>
            <table style="width: 375px" class="comboTable" cellspacing="0" cellpadding="0">
                            <tr>
                                <td style="width: 125px;" class="comboItemCell">
                                    <div class="comboItem">
                                        <%# DataBinder.Eval(Container.DataItem, "ProductName")%>
                                    </div>
                                </td>
                                <td style="width: 125px;" class="comboItemCell">
                                    <div class="comboItem">
                                        <%# DataBinder.Eval(Container.DataItem, "ProductID")%>
                                    </div>
                                </td>
                                <td style="width: 125px;" class="comboItemCell">
                                    <div class="comboItem">
                                        <%# DataBinder.Eval(Container.DataItem, "SupplierID")%>
                                    </div>
                                </td>
                            </tr>
                        </table>
         </ItemTemplate>
        </telerik:RadComboBox>

CS:

protected void RadComboBox1_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
    {
        string strSelectedValue = RadComboBox1.SelectedValue;
        string strSelectedItem = RadComboBox1.SelectedItem.Text;
    }

I just ran into this issue myself. This is quite a roundabout way of getting the selected value from a dropdown. Why does it not have a SelectedValue property? This could be useful for grabbing the selected value in codebehind, but also for declarative binding. I wish I could use it in my scenario - an Edit Form inside a grid that has dropdowns in it.
Instead I'll have to capture the event, save that value somehow, and then grab it when I want to save the record. Silly!

The RadComboBox has a SelectedValue property that you can accesss from the code-behind.

If you aren't adding items programmatically to the RadComboBox you need to set the DataValueField property. When the RadComboBox is bound to a data source, the SelectedValue property will be available in the code-behind.

When you bind the RadComboBox to a data source without specifying the DataValueField, you'll end up with empty string values for all your items.
