Namespace: DevExpress.Web
Assembly: DevExpress.Web.v24.2.dll
Declaration
Property Value
| Type | Description |
|---|---|
| Int32 | An integer value specifying the zero-based index of the TabBase amongst the tab control’s visible tabs. -1 if the tab is invisible. |
Remarks
Use the VisibleIndex property to control where the current tab is displayed within a tab control. If the VisibleIndex property is set to -1, the tab is not displayed.
A particular visible tab (tabbed page) can be obtained by its visible index using the TabCollection.GetVisibleTab (TabPageCollection.GetVisibleTabPage) method of the control’s ASPxTabControl.Tabs (ASPxPageControl.TabPages) collection. The total number of visible tabs (tabbed pages) is returned by the TabCollection.GetVisibleTabCount (TabPageCollection.GetVisibleTabPageCount) method.
Note that the VisibleIndex and TabBase.Visible properties are interdependent. The -1 value assigned to the VisibleIndex property sets the TabBase.Visible property to false. Setting the VisibleIndex property to a non-negative value makes the TabBase.Visible property set to true.
