Two Validation Groups in a Rad Wizard Control

Question

I have a "RadWizard" control (from Telerik) with two "RadWizardSteps" and two different "ValidationGroups".

When I click the first button (BtnArrayAdd), the validation for the "TxtArrayName" control works correct.

When I click the second button (BtnAdd), the validation checks only the "TxtAttributeName" control but not the "CbAttributeType" control.

When I remove the first step, the validation for both controls (TxtAttributeName & CbAttributeType) works correct.

What could be the problem?

Thx, Dominik

Answer 1

There are two possibilities with your code that are causing this issue. These are explained as below.

• When using a RequiredFieldValidator for radcombobox, you must keep in mind that the text part of selected item in radcombobox is being validated. So, looking at your markup for RequiredFieldValidator , it will only work if the text part of default selected item in radcombobox is an empty string. So, make sure the default item has its text set to empty string.
• If the text part of default item in radcombobox is not an empty string but something like Select a Type then all you need to do is set InitialValue property of your validator as in following markup.

Markup when default item has non-empty text

<asp:RequiredFieldValidator ID="CbAttributeTypeValidator" runat="server" 
      ControlToValidate="CbAttributeType" ValidationGroup="AttributeValidation"
      EnableClientScript="true" ForeColor="Red"
      InitialValue="Select a type"></asp:RequiredFieldValidator>
