Validate Item is selected when you click a tab on radtabstrip

[Richard]

I am trying to require an item to be selected in a radcombobox if you click on a tab on the radtabstrip.  Code below:

<telerik:RadComboBox ID="cbProject" runat="server" AutoPostBack="True" OnSelectedIndexChanged="cbProject_SelectedIndexChanged"
                    Height="120px" Sort="Ascending"  EmptyMessage="Enter Project" MarkFirstMatch="true" ValidationGroup="ClassValidationGroup">
                </telerik:RadComboBox>
                <asp:RequiredFieldValidator ID="reqCategory" ControlToValidate="cbProject"
                    runat="server" ErrorMessage="Please Select A Project" ValidationGroup="ClassValidationGroup"
                    InitialValue="" Display="Dynamic">
                </asp:RequiredFieldValidator>

<telerik:RadTabStrip ID="rpdTabStrip" Skin="Web20" runat="server" ClickSelectedTab="True"
                    AutoPostBack="True" SelectedIndex="0" CausesValidation="true">

I do not get any error if I click a tab.

Hello Richard,

In order to validate an item,you need to set the ValidationGroup property to the RadTabStrip .

MarkUp:

<telerik:RadTabStrip ID="rpdTabStrip" Skin="Web20" runat="server" ClickSelectedTab="True"
 AutoPostBack="True" SelectedIndex="0" ValidationGroup="ClassValidationGroup" >

Thanks,
Princy.
