Cross-thread Winforms control editing

Question

how can I edit the text in a windows form element if the code that is editing the text 'belongs' to a seperate thread from the one that contains the windows form? I get the exception:

Cross-thread operation not valid: Control 'textBox1' accessed from a thread other than the thread it was created on.

Thank you.

Please show the code....as this is not enough for us to help you! — t0mm13b, Apr 01 '10 at 19:28

You will need to use Control.Invoke method like this:

textbox1.Invoke((MethodInvoker)(() =>
   {
     textbox1.Text="some text";
   }));

Insert `Action y;` inside the class and execute the code `label1.Invoke(y = () => label1.Text = "Any text");` – Antonio Leite Dec 04 '16 at 09:45
