Public Property FirstVisibleResourceIndex As Integer
| Type | Description |
|---|---|
| Int32 |
An integer value which represents the zero-based index of the first visible resource.

Resources are visible to end-users if the SchedulerControl.GroupType property is set to the Resource value.
The maximum number of resources simultaneously displayed on screen depends on the View’s SchedulerViewBase.ResourcesPerPage property value. You can use the FirstVisibleResourceIndex property to scroll the Scheduler View to the specific resource.
The following code snippets (auto-collected from DevExpress Examples) contain references to the FirstVisibleResourceIndex property.
Note
The algorithm used to collect these code examples remains a work in progress. Accordingly, the links and snippets below may produce inaccurate results. If you encounter an issue with code examples below, please use the feedback form on this page to report the issue.
