Wizard fires events twice.

[Luis]

I have a basic wizard setup with OnNextButtonClick and OnFinishButtonClick events inside a panel that updates itself with a RadAjaxManager, and when I click on the  NEXT/FINISH buttons the event in the serverside fires twice I tested this with a breakpoint at the start of the method, my markup looks like this

<telerik:RadScriptManager ID="rasmMain" runat="server" />
    <telerik:RadAjaxManager ID="ramMain" runat="server" DefaultLoadingPanelID="rapMain">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="pTest">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="pTest" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>
    <telerik:RadAjaxLoadingPanel ID="rapMain" runat="server" />

    <telerik:RadAjaxPanel ID="rapResponseScripts" runat="server"></telerik:RadAjaxPanel>

    <asp:Panel ID="pTest" runat="server" ClientIDMode="Static">
        <telerik:RadWizard ID="rwNuevoCliente" runat="server" OnNextButtonClick="rwNuevoCliente_NextButtonClick" OnFinishButtonClick="rwNuevoCliente_FinishButtonClick">
            <WizardSteps>
                <telerik:RadWizardStep Title="Informacion General" CausesValidation="true" ValidationGroup="Step1" ImageUrl="../../images/png/store12.png" >
                </telerik:RadWizardStep>
                <telerik:RadWizardStep Title="Detalles de Contacto" CausesValidation="true" ValidationGroup="Step2" ImageUrl="../../images/png/call46.png">
                </telerik:RadWizardStep>
                <telerik:RadWizardStep Title="Condiciones Comerciales" ImageUrl="../../images/png/commercial40.png">
                </telerik:RadWizardStep>
            </WizardSteps>
        </telerik:RadWizard>
    </asp:Panel>

In the code behind I just have an empty method declaration.

Hi,
 I am also facing the same issue. Could anyone please help?

Hello,

Most probably the reason for this behavior is subscribing for these events in the markup code and in the code behind ( if you use VB.NET) as well. If you subscribe for the events in code behind using the VB.NET syntax 
//vb
​

Protected Sub rwNuevoCliente_NextButtonClick(sender As Object, e As WizardEventArgs) Handles rwNuevoCliente.NextButtonClick

   End Sub

please remove the highlighted line of code from the markup code
//markup code

<telerik:RadWizard ID="rwNuevoCliente" runat="server" OnNextButtonClick="rwNuevoCliente_NextButtonClick" OnFinishButtonClick="rwNuevoCliente_FinishButtonClick">
           <WizardSteps>
               <telerik:RadWizardStep Title="Informacion General" CausesValidation="true" ValidationGroup="Step1" ImageUrl="../../images/png/store12.png" >
               </telerik:RadWizardStep>
               <telerik:RadWizardStep Title="Detalles de Contacto" CausesValidation="true" ValidationGroup="Step2" ImageUrl="../../images/png/call46.png">
               </telerik:RadWizardStep>
               <telerik:RadWizardStep Title="Condiciones Comerciales" ImageUrl="../../images/png/commercial40.png">
               </telerik:RadWizardStep>
           </WizardSteps>
       </telerik:RadWizard>

Same applies for the FinishButtonClick event.

For reference I am attaching a sample project in C# where the events are fired only once as expected.

I noticed that in the example attached the wizard has its ClientIDMode Property set to "Static" after setting it in my page all the events fired just once   :)    I think its a weird behavior with the Dynamic ClientIDMode.

Thanks a lot.

I have subscribed for the event just once,that in the markup.
Setting the ClientIDMode to static solved the issue..

Setting the ClientIDMode to static solved this issue for me as well. The finish button click event was firing twice.

Hello John,

There was similar bug in RadWizard control that is already fixed so we are not aware of such issue now. Would you please share the exact code that will replicate the issue and elaborate which version of our controls are you using to replicate it.
