collections - Setting visiblilty of control using LINQ -


i'm working on refactoring code practice linq. reason can't code cooperate.

        //actioncontrols controlcollection var actioncontrols = flowlayoutpanel1.filtercontrols(c => c button);      //todo: optimize   foreach(var control in actioncontrols)   {       control.visible = workingitemdatatable.asenumerable().any(row => "btn" + row.field<string>("name") == control.name);   } 

what trying now.

flowlayoutpanel1.filtercontrols(c => c button && c.name == "btntaskinfo"//btntaskinfo visible                    || workingitemdatatable.asenumerable().any(row => "btn" + row.field<string>("name") == c.name)).cast<button>() 

but after casting button, can not figure out how set visible = false. advice?

you'd still need iterate controls, can this, assuming filtercontrols isn't more alias where:

var actioncontrols = flowlayoutpanel1.oftype<button>(); 

there "tricks" , shortcuts iterating , doing sets within lambda expression, makes code messy , hacks. can create own extension foreach (if there isn't 1 available if want anyway).

flowlayoutpanel1.oftype<button>().foreach(btn=>{btn.visible= ... });
