ComboBox does not work

[mohsen]

Hi,

I have a Telerik ComboBox, an ASP.NET TextBox, an ASP.NET RequiredFieldValidator(for TextBox), and a Button on an aspx form. At first, the ComboBox does work correctly and there is no problem, But, When I click on the button and my RequiredFieldValidator shows itself, then the ComboBox does not work. What's the problem?

My code is as bellow:

<telerik:RadComboBox ID="RadCmbCastingType" runat="server" dir="rtl" Width="190px"
                                            TabIndex="3">
                                            <CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation>
                                        </telerik:RadComboBox>

<asp:ImageButton ID="ImgInsert" runat="server" ImageUrl="~/App_Themes/SystemInfo/images/btn_save.gif"
                                            Style="height: 21px" TabIndex="12" CommandName="AddNew" />

Hi mohsen,

I've created a test project with the code you provided. Find it in the attached .zip file. At this moment RadComboBox is working fine. From the ticket info I see you are using Version 2010.1.519 of the RadControls. Can you confirm this? 

If you continue to experience problems,  please send me more info about your case.

Thank you.

My problem has not been solved.
I'm using the following code to bind the RadComboBox control:

Rad.DataSource = BCastingType.GetAll();
Rad.DataValueField = "Id";
Rad.DataTextField = "Title";
Rad.DataBind();
