SPSecurityTrimmedControl and PermissionsString

You shall sooner or later face a situation that you need to create a control under specific (custom) permission levels. SPSecurityTrimmedControl is one control that can give you such features.

A simple SPSecurityTrimmedControl can be added to you page as shown below:

<Sharepoint:SPSecurityTrimmedControl runat="server" PermissionsString="XYZ">
</Sharepoint:SPSecurityTrimmedControl>

Now, the XYZ can be any of the following as mentioned below.

Scenario: If I need to give specific users permissions to Edit the page; I use below lines of code...

<Sharepoint:SPSecurityTrimmedControl runat="server" PermissionsString="AddAndCustomizePages">
<div>
<a href="javascript:MSOLayout_ToggleLayoutMode();">Edit Page</a>
</div>
</Sharepoint:SPSecurityTrimmedControl>

Which means any user who belongs to a group with permissions for 'Adding and Customozing the Pages' can see the hyperlink Edit Page.
