Alias (Property)

In french: Alias

Caution: In WEBDEV, the Alias property works in a different way than in WINDEV and WINDEV Mobile.

The Alias property is used to get or change:

the alias of a window. To change the alias of a window, you can also use WinChangeAlias.
Reminder: Aliases can be used to identify a window opened multiple times (common case in an MDI application).
the alias of a pane in a Dynamic Tab control.

The Alias property returns the internal HTML/JavaScript name of a control.
WLanguage is less restrictive with control and page names than JavaScript: use of special characters, possibility to have two controls with the same name in the same page, etc.
Controls and pages are renamed in HTML pages. These names can be compressed for optimization purposes.
The Alias property gets the name used in the HTML page.

Example

// Open a new child window
OpenChild(WIN_Child, sFileName)
{sFileName}..X = 10
// {sFileName} = alias of the window

// -- Opening code of WIN_Child
PROCEDURE WIN_Child(sFileName)
MySelf.Alias = sFileName
// Define the alias
// Changes the title of the window that was just opened
{sFileName}..Title = "File = " + {sFileName}..Alias

// Retrieve the value of a control passed as parameter
ValueEdit1 is string = PageParameter(EDT_Edit1.Alias)
