    ExpressionErrorMessage Property
    In This Topic
    Stops the reporting engine from throwing exceptions and instead displays the provided string.
    Syntax
    'Declaration
     
    Public Property ExpressionErrorMessage As String
    public string ExpressionErrorMessage {get; set;}

    Property Value

    String. The default value is null.
    Remarks

    If this property is not set and an expression can't be parsed, or if you get a divide-by-zero type exception, ActiveReports will throw a ReportScriptException and stop the report from running.

    When this property is set to a valid string, the engine stops throwing exceptions and instead displays the specified string (like Excel). Set it to ### and try Sales/0 to test.

    Persistence: There is a new attribute called "ExprError" in .rpx files.

    Example
    private void arViewer_Load(object sender, System.EventArgs e)
    {
        SectionReport1 rpt = new SectionReport1();
        rpt.ExpressionErrorMessage = "oops";
        rpt.Run();
        this.arViewer.Document = rpt.Document;
    }
    Private Sub arViewer_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles arViewer.Load
        Dim rpt As New SectionReport1()
        rpt.ExpressionErrorMessage = "oops"
        rpt.Run()
        Me.arViewer.Document = rpt.Document
    End Sub
