When you specify values in the Properties window in the DataWindow Designer plug-in, you are setting properties of the DataWindow object and the controls, such as columns, buttons, and computed fields, on the DataWindow object.
Each control in the DataWindow has its own Properties window, because there are different sets of properties for each control. To access properties for individual controls, select the control and right-click Properties from the pop-up menu.
If several controls have the same property and you want them all to have the same value, you can select all the controls so that the Properties window shows the properties that they have in common. When you change the property value, it is applied to all selected controls.
For many properties, you can specify a DataWindow expression in the Properties window by selecting Expression in the list of values for the property. At runtime, the expression is evaluated for each row. When the expression includes row-dependent information in the calculation (such as data), each row can have a different value for the property. In the painter, you can see the results in the Preview view.
For information about the components of expressions, see the DataWindow Designer User’s Guide. For examples of expressions, see “Using DataWindow expressions as property values”. For information about setting values for properties that use expressions, see “Using DataWindow expressions as property values”.
