Question

I am making an application using Silverlight.

I must restict the access of some controls to some users.

Example: user1 can’t use the delete button …

Is there a framework or something that can help me ?
Would it help if I use sessions ?

Thanks.

Answer 1

I found a tool that do what I want. It is called Visual Guard. It’s a very nice and powerful tool.

In the documentation

Visual Guard has been designed to automate as much functionality as
possible in order to manage security in a PowerBuilder application.
This is performed at several levels:

Managing actions specific to PowerBuilder Visual Guard manages the
modification of key PowerBuilder object properties: •
Enabling/disabling a control (button, graph, listbox, etc.). ). •
Making a control (button, graph, listbox, etc.) visible/invisible. •
Enabling/disabling menu items. • Making menu items as well as their
toolbar icons visible/invisible. • Hiding/showing a datawindow
column. • Enabling/disabling a datawindow column • Changing the
WHERE clause of a datawindow sql statement. • Filtering of rows
displayed in a datawindow. • Modifying text controls (Column names,
contextual help, etc.) • Modifying the properties of a datawindow
element (data input restrictions, changing a column’s validation
message or validation rules, etc.).

and much much more

I hope that it will help someone
