title: How to show file path in a textbox by default on starting WPF application
body: <p>I have a textbox and a button along side it. The button click opens a folder browser to a default root folder from which I can select the files. I want to display this entire file path in the textbox automatically when I launch the application. This is the code that I have now. </p>
  
  <pre><code>    private void SelecttxtBox_TextChanged(object sender, System.Windows.Controls.TextChangedEventArgs e)
      {
          SelecttxtBox.Text = fldDlg.SelectedPath;
      }
  </code></pre>
  
  <p>However, this inputs the path into the textbox AFTER the button click whereas I want to populate it BEFORE clicking on the button.</p>
  
  <p>I appreciate the help, thank you</p>
