SnapControl.SnapMailMergeActiveRecordChanging Event

Occurs before traversing to the next data record in a mail merge data source.

Namespace: DevExpress.Snap

Assembly: DevExpress.Snap.v19.1.dll

Declaration

C#

public event EventHandler SnapMailMergeActiveRecordChanging

VB.NET

Public Event SnapMailMergeActiveRecordChanging As EventHandler

Event Data

The SnapMailMergeActiveRecordChanging event's data class is EventArgs.

Remarks

When a mail merge is performed in the user interface, the SnapMailMergeActiveRecordChanging event can be raised asynchronously, requiring use of the SnapControl‘s InvokeRequired property in the event handler to determine if it is necessary to call the SnapControl.Invoke method to execute a delegate in a thread that owns the control.

C#

void snapControl1_SnapMailMergeActiveRecordChanging(object sender, EventArgs e)
{
    Action d = delegate {
        // Add a method to handle the event.
    };
    if (this.snapControl1.InvokeRequired)
        this.snapControl1.Invoke(d);
    else
        d();
}

VB.NET

Private Sub snapControl1_SnapMailMergeActiveRecordChanging(ByVal sender As Object, ByVal e As EventArgs)
    Dim d As Action = Sub()
        ' Add a method to handle the event.
    End Sub
    If snapControl1.InvokeRequired Then
        snapControl1.Invoke(d)
    Else
        d()
    End If
End Sub
