item.isenabled = false; 

any ideia how can ? thanks!

a page can have 1 child uielement (uielement equivalent of control), use reference it:

uielement maincontrolonpage = this.content; 

usually, 1 child panel control of kind, such grid. use following loop through children of panel control:

foreach (uielement element in this.mainpagegrid.children) {     // element }
