To show data on a form, you add controls to the form. To add a control, you use one of the following techniques:

You drag a field or a field group from the data source of the form to the Design node of the form.
You right-click the Design node of the form and add a control from the list of available controls.
You copy an existing control from one form to another form or to another location in the same form.

The procedure you use to add form control depends on whether you want to add a bound control, an unbound control, or a calculated control. For more information about the different kinds of controls, see Bound Controls, Unbound Controls, and Calculated Controls.

Note

When you add a control to a form, the size of the form adjusts automatically.

The following sections show how to add a bound, unbound, or calculated control to a form.

To Add a Bound Control

Expand the Data Sources node of the form.
Expand the Fields node for one of the data sources.
Click a field in the field list. To move more than one field, click each field you want to appear on the form.
Drag the selected field from the field list to the Design node of the form. A control is added to the form. The control is bound to the field from the Data Sources node. The type of control is determined by the data type of the field. In addition, properties of the control are set to default values that are based on the data type of the field.

Note

To use a field group from a table in the data source, drag the complete field group instead of individual fields from your data source.

To Add an Unbound Control

Expand the Designs node of the form.
Right-click the Design node, click New Control, and then click the type of control you want to add.
View the property sheet for the control and set values for the properties of the control. As a minimum, set the Name and Label properties.

Note

You can change an unbound control to a bound control by setting the DataSource and DataField properties of the control. However, you should add a bound control to a form by dragging the field to the Design node whenever possible. The control receives default property values that are inherited from the field.

To Add a Calculated Control

Create a method that calculates the value to be displayed in the control. You should add the method to the table instead of the form. If you add the method to the table, you can reuse the code in other forms.

For example, you add the following subtotalSum method to a table named MyTable. The method calculates the sum of the SubTotal_A and SubTotal_B fields. Notice how the method includes the display modifier that enables you to show the result of the computation.

        display int subtotalSum(MyTable t)
        {
            return t.SubTotal_A + t.Subtotal_B;
        }

Right-click the Design node of the form, click New Control, and then click the type of control you want to add. For example, you might click IntEdit or RealEdit to add a control that can display a sum.
View the property sheet for the control. Set the DataSource property to the name of the table. Set the DataMethod property to the name of the method that calculates the field value. For example, you set DataMethod to subtotalSum to have the control show the value the method returns.
