Checkbox into Combobox

[Manuel]

Hello, I need to write the items checked in combobox text separated by ",".
  Likewise, delete the items I unchecked in the text of combobox

Check A and B --> combobox text =A,B
uncheck B --> combobox text=A

<telerik:RadComboBox ID="combo_empleados" AllowCustomText="true" Filter="Contains"
            
                EnableLoadOnDemand="true"  runat="server" Width="70%">

                <ItemTemplate>
                     <div >
                          <asp:CheckBox ID="chk1" runat="server" checked="false" AutoPostBack="False" Text=""/> <%# DataBinder.Eval(Container, "Text") %>  
                         
                     </div>
                </ItemTemplate>
            
            </telerik:RadComboBox>

Hi Manuel,

Please try to set CheckBoxes=true of RadComboBox to achieve your scenario.
ASPX:

<telerik:RadComboBox ID="combo_empleados" AllowCustomText="true" Filter="Contains"
            CheckBoxes="true" CheckedItemsTexts="DisplayAllInInput" EnableLoadOnDemand="true"
            runat="server" DataSourceID="SqlDataSource1" DataTextField="CustomerID">
        </telerik:RadComboBox>
        <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"
            SelectCommand="SELECT [CustomerID] FROM [Orders]">
</asp:SqlDataSource>

Thanks,
Shinu.
