PrintingSystemBase.EditingFieldChanged Event

Occurs each time a value of an editing field changes.

Namespace: DevExpress.XtraPrinting

Assembly: DevExpress.Printing.v18.2.Core.dll

Declaration

C#

public event EventHandler<EditingFieldEventArgs> EditingFieldChanged

VB.NET

Public Event EditingFieldChanged As EventHandler(Of EditingFieldEventArgs)

Event Data

The EditingFieldChanged event's data class is EditingFieldEventArgs. The following properties provide information specific to this event:

Property	Description
EditingField	Gets an editing field whose value has been changed.

Remarks

Use the following properties to access an editing field’s value:

• EditingField.EditValue
• CheckEditingField.CheckState
• ImageEditingField.ImageSource

Each time the current field value changes, the EditingFieldChanged event occurs, allowing you to respond to this action (for instance, validate input data or format the edited value). The code snippet below demonstrates how to apply the same currency format to an unbound and data-aware control.

C#

using DevExpress.XtraPrinting;
// ...

private void XtraReport1_BeforePrint(object sender, System.Drawing.Printing.PrintEventArgs e) {
    PrintingSystem.EditingFieldChanged += PrintingSystem_EditingFieldChanged;
}

void PrintingSystem_EditingFieldChanged(object sender, EditingFieldEventArgs e) {
    if (e.EditingField.Brick.TextValue != null) {
        e.EditingField.Brick.TextValueFormatString = "{0:c2}";
        e.EditingField.Brick.Text = string.Format(e.EditingField.Brick.TextValueFormatString, e.EditingField.Brick.TextValue);
    }
    else {
        e.EditingField.Brick.Text = string.Format("{0:c2}", System.Convert.ToDouble(e.EditingField.Brick.Text));
    }
}

VB.NET

Imports DevExpress.XtraPrinting
' ...

Private Sub XtraReport1_BeforePrint(sender As Object, e As System.Drawing.Printing.PrintEventArgs)
    AddHandler PrintingSystem.EditingFieldChanged, AddressOf PrintingSystem_EditingFieldChanged
End Sub

Private Sub PrintingSystem_EditingFieldChanged(sender As Object, e As EditingFieldEventArgs)
    If e.EditingField.Brick.TextValue IsNot Nothing Then
        e.EditingField.Brick.TextValueFormatString = "{0:c2}"
        e.EditingField.Brick.Text = String.Format(e.EditingField.Brick.TextValueFormatString, e.EditingField.Brick.TextValue)
    Else
        e.EditingField.Brick.Text = String.Format("{0:c2}", System.Convert.ToDouble(e.EditingField.Brick.Text))
    End If
End Sub
