Question

I have a function LoadData with huge number of WinForm controls and it loads data from database in to the control.
Now it’s become very slow, should i use threading, if yes then pls suggest a good sample, I already tried the MSDN sample

But it’s not useful to me, it’ll required lot of change in my code.

Answer 1

I assume you have a lot of code that interacts with UI and you want to do from background thread.

You could add a method like this:

private static void UpdateControl(Control control, Action action)
{
    if (control.InvokeRequired)
        control.Invoke(action);
    else
        action();
}

The usage:

Old

 textBox.Text = "Something";

New

 UpdateControl(textbox, () => { textBox.Text = "Something" });

---

Or extension method, to make usages shorter

public static class ControlExtension
{
    public static void UpdateControl(this Control control, Action<Control> action)
    {
        if (control.InvokeRequired)
            control.Invoke((Action)(() => action(control)));
        else
            action(control);
    }
}

Usage:

textBox.UpdateControl(arg => arg.Text = "Something");
