The FormDataSource class contains properties that define the behavior of data sources in forms.

public class FormDataSource : Dynamics.AX.Application.FormObjectSet

[<Microsoft.Dynamics.Ax.Xpp.KernelClass>]

Public Class FormDataSource
Inherits FormObjectSet

Attributes: KernelClassAttribute

Remarks

By overriding the methods on the class, you can customize the behavior for the method actions, such as insertion or validation, for a specific form. The FormDataSource class is also used to determine how the data source table is related to other data sources (tables) that are displayed in the form. To override some of the methods in the FormDataSource class, right-click the Methods node for a form data source, and then click Override Method. When you create methods on a form, you should use a _ds identifier to reference the FormDataSource object for a particular class. For example, CustTrans_ds references the FormDataSource object for the CustTrans data source on the form, and CustTrans_ds.executeQuery() executes the FormDataSource.executeQuery method on the CustTrans data source. Several FormDataSource methods return a FormObjectSet object. To use the methods that are defined on the FormDataSource method on this object, you must typecast it to a FormDataSource object.

The following example supplies a custom query for a field instead of the automatically generated query. It overrides the performFormLookup method on the field.

public void performFormLookup(FormRun _p1, FormControl _formControl)  
{ 
    FormDataSource formDataSource; 
    QueryRun queryRunGenerated; 
    // The FormDataSource object retrieved from the FormRun parameter. 
    formDataSource = _p1.dataSource(1); 
    // Get the generated query. 
    queryRunGenerated = formDataSource.queryRun(); 
    // Modify the query. 
    // ... 
    // Call the standard implementation of performFormLookup 
    // with the parameters supplied in this method. 
    super(_p1, _formControl); 
}
