public virtual System.string DataField {get; set;} | |
Property Value
Name of the data bound field. Default is an empty string; the control is not bound.Remarks
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 DataValue property. It then passes through any OutputFormat 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, a TextBox control or a GroupHeader's DataField property 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.
When using XML, the DataField must be set to a valid XPath expression.
