RepositoryItemTrackBar.ShowValueToolTip Property

Gets or sets whether the track bar shows the current value in a tooltip when a user moves a thumb.

Namespace: DevExpress.XtraEditors.Repository

Assembly: DevExpress.XtraEditors.v21.1.dll

Declaration

[DefaultValue(false)]
[DXCategory("Behavior")]
public bool ShowValueToolTip { get; set; }

Property Value

Type Default Description
Boolean

false

true if the track bar shows the current value in a tooltip when a user moves a thumb; otherwise, false.

Remarks

The default tooltip contains the current value. You can handle the RepositoryItemTrackBar.BeforeShowValueToolTip event to display a custom tooltip.

Example

The following code shows how to implement custom tooltips for a TrackBarControl’s thumb.

To enable tooltips, the RepositoryItemTrackBar.ShowValueToolTip property is set to true. Custom tooltips are implemented via the TrackBarControl.BeforeShowValueToolTip event. The result is shown below:

TrackBar_CustomTooltips

trackBarControl1.Properties.ShowValueToolTip = true;
//...

private void trackBarControl1_BeforeShowValueToolTip(
object sender, DevExpress.XtraEditors.TrackBarValueToolTipEventArgs e) {
    e.ShowArgs.ToolTip = string.Format("Value = {0}", trackBarControl1.Value);
}
