WizardControl.NextClick Event

Fires when the Next button is clicked. Allows you to cancel the operation or navigate to a custom page.

Namespace: DevExpress.XtraWizard

Assembly: DevExpress.XtraWizard.v19.1.dll

Declaration

C#

public event WizardCommandButtonClickEventHandler NextClick

VB.NET

Public Event NextClick As WizardCommandButtonClickEventHandler

Event Data

The NextClick event's data class is WizardCommandButtonClickEventArgs. The following properties provide information specific to this event:

Property	Description
Handled	Gets or sets whether an event was handled.
Page	Gets the processed wizard page. Inherited from WizardPageEventArgs.

Remarks

When you click the Next button, the WizardControl automatically navigates to the next wizard page (the WizardControl.Pages collection specifies the navigation order).

You can handle the NextClick event to modify the default navigation route.

To navigate to a custom page, assign this page to the SelectedPage event parameter. You also need to set the WizardCommandButtonClickEventArgs.Handled parameter to true to cancel the default navigation.

The WizardPageEventArgs.Page event parameter allows you to obtain the current page.

To learn more, see Page Events.

Example

The following example handles the WizardControl.NextClick event to change the default navigation route. When a user clicks the Next button in Page1, the WizardControl navigates to Page3.

C#

private void wizardControl1_NextClick(object sender, DevExpress.XtraWizard.WizardCommandButtonClickEventArgs e) {
    if (e.Page.Text == "Page1") {
        WizardControl wc = sender as WizardControl;
        wc.SelectedPage = wc.Pages.OfType<WizardPage>().FirstOrDefault(x => x.Text == "Page3");
        e.Handled = true;
    }
}

VB.NET

Private Sub WizardControl1_NextClick(sender As Object, e As DevExpress.XtraWizard.WizardCommandButtonClickEventArgs) _
    Handles WizardControl1.NextClick
    If e.Page.Text = "Page1" Then
        Dim wc As WizardControl = TryCast(sender, WizardControl)
        wc.SelectedPage = wc.Pages.OfType(Of WizardPage)().FirstOrDefault(Function(x) x.Text = "Page3")
        e.Handled = True
    End If
End Sub

Example 2

In the following sample, a Wizard Control has 5 pages:

• a Welcome Page
• an Interior Page with a RadioGroup editor that offers three navigation options: Page 3, Page 4, or the final completion page;
• two more Interior Pages: Page 3 and Page 4;
• a Completion Page.

The code below illustrates how to navigate to a correct page depending on a choice a user makes in the second page.

C#

bool pageSkipped = false;

private void wizardControl1_NextClick(object sender, DevExpress.XtraWizard.WizardCommandButtonClickEventArgs e)
{
    if (e.Page == wizardPage1)
    {
        switch (radioGroup1.EditValue.ToString())
        {
            case ("ToPage2"):
                wizardControl1.SelectedPage = wizardPage2;
                e.Handled = true;
                break;
            case ("ToPage3"):
                wizardControl1.SelectedPage = wizardPage3;
                e.Handled = true;
                pageSkipped = true;
                break;
            case ("ToFinalPage"):
                wizardControl1.SelectedPage = completionWizardPage1;
                e.Handled = true;
                pageSkipped = true;
                break;
        }
    }
}

private void WizardControl1_PrevClick(object sender, DevExpress.XtraWizard.WizardCommandButtonClickEventArgs e)
{
    if (pageSkipped)
    {
        wizardControl1.SelectedPage = wizardPage1;
        pageSkipped = false;
        e.Handled = true;
    }
}

VB.NET

Private pageSkipped As Boolean = False

Private Sub wizardControl1_NextClick(ByVal sender As Object, ByVal e As DevExpress.XtraWizard.WizardCommandButtonClickEventArgs)
    If e.Page = wizardPage1 Then
        Select Case radioGroup1.EditValue.ToString()
            Case ("ToPage2")
                wizardControl1.SelectedPage = wizardPage2
                e.Handled = True
            Case ("ToPage3")
                wizardControl1.SelectedPage = wizardPage3
                e.Handled = True
                pageSkipped = True
            Case ("ToFinalPage")
                wizardControl1.SelectedPage = completionWizardPage1
                e.Handled = True
                pageSkipped = True
        End Select
    End If
End Sub

Private Sub WizardControl1_PrevClick(ByVal sender As Object, ByVal e As DevExpress.XtraWizard.WizardCommandButtonClickEventArgs)
    If pageSkipped Then
        wizardControl1.SelectedPage = wizardPage1
        pageSkipped = False
        e.Handled = True
    End If
End Sub
