Using SPSecurityTrimmedControl in code behind

Scenario:
I was suppose to write a webpart that display edit panel only if the user has certian permissions.

Solution:
I used SPSecurityTrimmedControl in my code behind

Code:

public void override CreateChildcontrols(){
SPSecurityTrimmedControl stcEdit= new SPSecurityTrimmedControl();
stcEdit.Permissions = SPBasePermissions.EditListItems;

Panel pnlEdit = new Panel();
stcEdit.Controls.Add(pnlEdit);
this.Controls.Add(stcEditItem);
}
