public int VisibleIndex { get; set; }

Property Value

Type Description

An integer value specifying the zero-based index of the SplitterPane amongst visible panes at the same level. -1 if the pane is invisible.


Use the VisibleIndex property to control where the splitter pane is displayed amongst other panes of the same level. If the VisibleIndex property is set to -1, the pane is not displayed.

A particular visible pane can be obtained by the pane’s visible index using the SplitterPaneCollection.GetVisiblePane method of the parent pane’s SplitterPane.Panes collection (or the ASPxSplitter.Panes collection of a splitter control in the case of the root level panes). The total number of visible items at a particular level is returned by the SplitterPaneCollection.GetVisiblePaneCount method of the corresponding pane collection.

Note that the VisibleIndex and SplitterPane.Visible properties are interdependent. The -1 value assigned to the VisibleIndex property sets the SplitterPane.Visible property to false. Setting the VisibleIndex property to a non-negative value sets the SplitterPane.Visible property to true.
