c# - Cross-thread operation not valid control -

-

I know there are a lot of tips about my question but I have not found solutions for my case ... < / P>

I have a panel which I add control over the runtime, I tried this code but it does not help me, and says an error:

Cross- Thread operation is not valid

Here my code: 

  Public Zero AddControlToPanel (panel panel, control ctrl In addition to the thread was less addressed Control accessed from a thread 1 'Panel') {If (panel.InvokeRequired) {panel.Invoke ((MethodInvoker) representative {AddControlToPanel (panel, ctrl);}); Return; } And panel. Control. Add (ctrl); }

And I call it like this: 

  AddControlToPanel (panel1, ctrl); You can create a control extension within the namespace of your project like this:

and use it within your code like this: 

  this.UIThread ((=) => (panel1.Controls. Add (Ctrl);});
