Disable navigation via Navigation Bar

[Stephan Reisinger]

Good afternoon !

Is there an easy way to disable the navigation inside the RadWizards Navigation Bar ?

Reason:

I would like to validate the RadWizardSteps during an Ajax PostBack when the NextButtonClick event is fired.
The EventArgs during the ActiveStepChanged event do not provide CurrentStepIndex or other information of the WizardEventArgs

Code:

Dim __Wizard As RadWizard = sender

 Try

     Select Case e.CurrentStepIndex

         Case o_Step_Company.Index

             Me._Validate_Companies()

         Case o_Step_DateFilter.Index

             Me._Validate_Dates()

     End Select

 Catch vx As ValidationException

     vx.CreateNotification()

     __Wizard.ActiveStepIndex = e.CurrentStepIndex

 Catch ex As System.Exception

     ex.SaveToDatabase()
     ex.CreateNotification()

 End Try

Thanks,

S. REISINGER

Hello,

You can use the NavigationBarButtonClick server-side event where the current and next step indexes are available. Here is a sample code that worked correctly at my side:

protected void Unnamed_NavigationBarButtonClick(object sender, WizardEventArgs e)
   {
       if (String.IsNullOrEmpty(TextBox1.Text))
       {
           ((RadWizard)sender).ActiveStepIndex = e.CurrentStepIndex;
       }
   }

Hope this information will be helpful.

Why don't you use field validation ?  The samples on the site contains field validation

Hello,

Yes this is another way to handle the scenario with server validation as for example in the code below or with client validation as explained in this help topic.:

<telerik:RadWizard ID="RadWizard6" runat="server" OnNextButtonClick="RadWizard6_NextButtonClick">
               <WizardSteps>
                   <telerik:RadWizardStep ID="RadWizardStep1" Title="Personal Info" runat="server" StepType="Step" ValidationGroup="personalInfo">
                       <div class="inputWapper first">
                           <asp:Label ID="Label3" Text="First Name: *" runat="server" AssociatedControlID="FirstNameTextBox" />
                           <telerik:RadTextBox ID="FirstNameTextBox" runat="server" ValidationGroup="personalInfo" Width="320px"></telerik:RadTextBox>
                           <asp:RequiredFieldValidator ID="FirstNameRequiredFieldValidator" runat="server" ControlToValidate="FirstNameTextBox"
                               EnableClientScript="false" ValidationGroup="personalInfo" ErrorMessage="required field" CssClass="validator" ForeColor="Red"></asp:RequiredFieldValidator>
                       </div>
                       <div class="inputWapper">
                           <asp:Label ID="Label4" Text="Last Name: *" runat="server" AssociatedControlID="LastNameTextBox" />
                           <telerik:RadTextBox ID="LastNameTextBox" runat="server" ValidationGroup="personalInfo" Width="320px"></telerik:RadTextBox>
                           <asp:RequiredFieldValidator ID="LastNameRequiredFieldValidator" runat="server" ControlToValidate="LastNameTextBox"
                               EnableClientScript="false" ValidationGroup="personalInfo" ErrorMessage="required field" CssClass="validator" ForeColor="Red"></asp:RequiredFieldValidator>
                       </div>
                   </telerik:RadWizardStep>
                   <telerik:RadWizardStep Title="SecondStep">
                       <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
                   </telerik:RadWizardStep>
               </WizardSteps>
           </telerik:RadWizard>

I used demo code for wizard and validation but the client side validation does not work
in fact client validation function does not fire at all

Hello Mostafa,

I have tested the code provided in the previous post and it worked correctly at my side just after removing the EnableClientScript="false" that is set.

Hope this will help you solve the issue.
