Change button content in WPF

Question

I have:

private void button1_MouseEnter(object sender, EventArgs e)
{
    for (int i = 0; i > 2; i++) 
    {     
        button1.Content = Convert.ToString(i         


        

Answer 1

Your for loop never execute because you have wrong condition, change it to following code:

for (int i = 0; i < 2; i++)

Also you should use BackgroundWorker (msdn) to update your GUI dynamicly.

private void button1_MouseEnter(object sender, MouseEventArgs e)
{
    BackgroundWorker worker = new BackgroundWorker();
    worker.DoWork += delegate
    {
        for (int i = 0; i < 2; i++)
        {
            this.Dispatcher.Invoke((Action)(() => { btn.Content = Convert.ToString(i); }));
            System.Threading.Thread.Sleep(1000);
        }                
    };
    worker.RunWorkerCompleted += delegate { tekst.Text = "Mouse Enter"; };
    worker.RunWorkerAsync();
}
