DataField Property (ARControl)

GrapeCity.ActiveReports Assembly > GrapeCity.ActiveReports.SectionReportModel Namespace > ARControl Class : DataField Property

Gets or sets the field name from the data source to bind to the control.

Public Overridable Property DataField As String
public virtual string DataField {get; set;}

Property Value

Name of the data bound field.  Default is an empty string; the control is not bound.

When the DataField property is set to a field contained within the DataSource, ActiveReports binds the field's data from each record to the control. The recordset data is first saved into the Value property. It then converts to any output format and is set as the control's text.

The DataField property can also be used to perform calculations using a scripting expression beginning with an equals sign (=). This allows fields to be set up to display calculated results. For example, field control or data field's group field section can be set to an expression such as "=UnitPrice * Qty" or "=CompanyName.Trim()" where UnitPrice, Qty and CompanyName are members of the report's Fields collection.

Add an equals sign (=) at the beginning when using parameters in a DataField property.

When using XML, the DataField must be set to a valid XPath expression.

private void SectionReport1_ReportStart(object sender, System.EventArgs eArgs)
    this.textBox2.DataField = "CustomerID";
Private Sub SectionReport1_ReportStart(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.ReportStart
    Me.TextBox2.DataField = "CustomerID"
End Sub
