Namespace: DevExpress.XtraCharts.Wizard

Assembly: DevExpress.XtraCharts.v20.1.Wizard.dll

Declaration

public WizardGroup RegisterGroup(
    string groupName
)
Public Function RegisterGroup(
    groupName As String
) As WizardGroup

Parameters

Name Type Description
groupName String

A string, specifying a name of the group. Should be unique within the Chart Wizard instance.

Returns

Type Description
WizardGroup

A WizardGroup class instance, representing a group of pages in the Chart Wizard.

Remarks

The method checks the name for uniqueness and creates a group. To display a group in the Wizard, you should register a page that belongs to the group. This technique is illustrated by the following code example.

Examples

The following example demonstrates how to add a new group with a new page to the Chart Wizard at runtime.

First, create a control that becomes a page's content. Create a new control that inherits from the WizardControlBase and drop the ChartControl onto it. This follows because the page is intended to customize the chart. The page should contain a chart control to display the changes as the settings are modified.

Then, use the following code to create a group and a page. You can handle the WizardPage.InitializePage event to get access to the contained chart control.

using DevExpress.XtraCharts.Wizard;
//...

private void ShowNewWizard() {
    // Create a Wizard instance.
    ChartWizard wiz = new ChartWizard(this.chartControl1);

    // Create a new group.
    WizardGroup MyWizardGroup = wiz.RegisterGroup("NewGroup");

    // Create a new page with a "MyPage" name, "MyHeader" as a caption, "MyDesription" 
    // as a description, without image. It contains the UserControl1.
    WizardPage MyWizardPage =  MyWizardGroup.RegisterPage(typeof(UserControl1), 
        "MyPage", "MyHeader", "MyDesription", null);

    // Subscribe to the InitializePage event.
    MyWizardPage.InitializePage += new InitializePageEventHandler (MyWizardPage_InitializePage);

    // Invoke the Wizard.
    wiz.ShowDialog();
}

void MyWizardPage_InitializePage(object sender, InitializePageEventArgs e) {
    e.Chart = ((UserControl1)e.Control).chartControl1;
}
