Question

is it possible to move a control or at least copy the control to another thread then the one it was created on. The reason being is I want the control to load entirely in a background thread and then once it’s done loading I want to move the control to another thread. For example:

BackgrundworkRunasync(object sender, DoWorkEventArgs e )
{
     var GetData = GetData();
     CreateControl mycontrol = new CreateControl() //Tyep of WindowsForm
     mycontrol.Data = GetData; 
     e.Result = mycontrol;
}

BackGroundWorkerComplete ( object sender, RunWorkerCompletedEventArgs e )
{
   CreateControl con = (CreateControl)e.Result;
   con.mdiparent = this;
   con.Show();

//Of course this is a cross threading exception. Can I move this control to the current thread or even create a control in the current thread and do a deep copy? Optimally I just want to move the control to another thread, can you do this?
}

Answer 1

No, it’s not possible. The control must be created on the main thread.

You should modify your code like that:

BackgrundworkRunasync(object sender, DoWorkEventArgs e )
{
     e.Result = GetData();
}

BackGroundWorkerComplete ( object sender, RunWorkerCompletedEventArgs e )
{
    CreateControl mycontrol = new CreateControl() //Tyep of WindowsForm
     mycontrol.Data = e.Result; 
   myControl.mdiparent = this;
   myControl.Show();
}
