Data Binding a Component Attribute

From the Property Inspector and Bind to Data dialog, you can:

• bind a property to data
• edit a property's data binding
• delete a property's data binding
• bind a complex attribute to data.

Note: If you need help on using the Bind to Data dialog, click the Help button from within the dialog.

To bind a property to data, or to edit a property's data binding:

1. In the UIX Visual Editor or Design Structure Window of the desired file, select the component you wish to edit.
2. In the Property Inspector, find the desired property:
   • If appears to the left of the property name, then the property is a simple databound property. An EL syntax expression appears in the right column. Click in the right column, then click to open the Bind to Data dialog.
   • If does not appear to the left of the property name, then click in the right column next to the property name. If appears, then the property is a complex attribute. Proceed to the instructions for binding a complex attribute to data.
   • If the property is not yet databound and is not a complex attribute, click the right column next to the property, then in the Property Inspector toolbar click . If the property did not have a value, then the EL syntax expression ${null} appears in the right column. Otherwise, the property's previous value appears as an EL syntax expression, e.g., ${'value'}. Click in the right column again, then click to open the Bind to Data Dialog.

     The dialog appears, with the name of the property as its title.

3. Enter or edit the data binding. For more help on using the dialog, click the Help button from within the dialog.
4. Click OK to finish.

To unbind a property:

1. In the UIX Visual Editor or Design Structure Window of the desired file, select the component whose property you wish to unbind.
2. In the Property Inspecto,r click the right column next to the property, then click .

   The dialog appears with the name of the property as its title. The Bind checkbox is selected, indicating that the property is databound.

3. Clear the Bind checkbox.
4. If you want to set the property to a static value, enter the value in the Expression text box.
5. Click OK to finish.

To bind a complex attribute to data, or to edit a complex attribute's data binding:

1. If you have not already done so, in the UIX Visual Editor or Design Structure Window of the desired file select the component you wish to edit.
2. If you have not already done so, in the Property Inspector click the right column next to the complex attribute.
3. Click to open the complex attribute's editor dialog.
4. In the complex attribute dialog:
   • If the attribute has subproperties, then you can bind them to data or edit their existing data binding by clicking to the right of the subproperty's input control. This opens the Bind to Data dialog.

     If does not appear, then the subproperty cannot be bound to data.

   • You can always bind the entire complex attribute to data or edit its existing data binding from the Advanced tab. To do this, select the Advanced tab, then select to open the Bind to Data dialog.

   The dialog appears, with Bind to Data as its title.

5. Enter or edit the data binding. For more help on this, click the Help button.
6. Click OK to finish your work in the Bind to Data dialog.
7. Click OK again to finish your work in the complex attribute editor dialog.
