How To Display Ellipses Button for a UserControl Property

MORE INFORMATION

To show the ellipses button for a property, you can set the appropriate options in the Procedure Attributes dialog.

The Procedure Attributes dialog box allows you to set a variety of attributes by clicking the Advanced button. The "Use This Page in Property Browser" procedure attribute specifies which property page is associated with a specific property. It is this attribute that tells Visual Basic to display the ellipses button in the property window. A property page can be one of the standard property pages like Font or Color or a property page you create.

To Enable the Ellipses Button of a Property

1. Open the UserControl project in Visual Basic.
2. From the Tools Menu, click Procedure Attributes. The Procedure Attributes dialog box appears.
3. In the Procedure Attributes dialog box, click Advanced >>. The Procedure Attributes dialog box expands to display additional attributes.
4. In the Procedure ID listbox, select the name of the property.
5. In the Use This Page in Property Browser list box, select the property page to displayed for the property. Click Apply to apply this setting, then click OK to close the dialog box.
   
   The ellipses button should now appear in the container property page. If the form hosting the UserControl is still open in your project, it may be necessary to right-click on the form (in design mode) and select "Update UserControl" to refresh the property window.
