MarginsChangeEventArgs is the data class for the following events:

• PrintingSystemBase.AfterMarginsChange
• PrintingSystemBase.BeforeMarginsChange

Remarks

The PrintingSystemBase.BeforeMarginsChange event occurs before page margin(s) change.

The MarginsChangeEventArgs.Side property contains the changed page margin. The value is taken from the MarginSide enumeration.

Example

The following example uses the PrintingSystemBase.BeforeMarginsChange event handler to change the margin size to the default value of 100, if the margins have been moved:

C#

using DevExpress.XtraPrinting;
// ...

private void printingSystem1_BeforeMarginsChange(object sender, 
MarginsChangeEventArgs e) {

    if (e.Value != 100) e.Value = 100;

}

VB.NET

Imports DevExpress.XtraPrinting
' ...

Private Sub PrintingSystem1_BeforeMarginsChange(ByVal sender As Object, ByVal e _
    As MarginsChangeEventArgs) Handles PrintingSystem1.BeforeMarginsChange

    If e.Value <> 100 Then e.Value = 100

End Sub
