ConstantLineMovedEventArgs Class
In This Article
Provides data for the ChartControl.ConstantLineMoved event.
Namespace: DevExpress.XtraCharts
Assembly: DevExpress.XtraCharts.v24.2.dll
NuGet Package: DevExpress.Charts
#Declaration
#Remarks
The ChartControl.ConstantLineMoved event occurs when a user moves a constant line. A constant line can be moved if its ConstantLine.RuntimeMoving property is set to true.
Note that ConstantLineMovedEventArgs objects are automatically created, initialized and passed to ChartControl.ConstantLineMoved event handlers.
#Example
The following example adds a horizontal constant line with an editable title. Once a user moves a constant line, the title is updated to display the current constant line value.
private void OnFormLoad(object sender, EventArgs e) {
ConstantLine constantLine = new ConstantLine();
constantLine.AxisValue = 65.0;
constantLine.Title.Text = "Title";
constantLine.RuntimeTitleEditing = true;
constantLine.RuntimeMoving = true;
XYDiagram diagram = chartControl1.Diagram as XYDiagram;
diagram.AxisY.ConstantLines.Add(constantLine);
chartControl1.ConstantLineMoved += OnChartControlConstantLineMoved;
}
private void OnChartControlConstantLineMoved(object sender, ConstantLineMovedEventArgs e) {
e.ConstantLine.Title.Text = String.Format("{0:f3}",e.ConstantLine.AxisValue);
}
