    <p>I've just finished developing a touch screen Kiosk, no physical keyboard. I too found the osk limiting.</p> <p>With the help of a graphic designer, we created our own keyboard, buttons with the background of a key, and the content (or Tag) matching the intent of the button. Assign most buttons to a common event handler that inserts the text at the CaretIndex of the selected control.</p> <p>Use seperate handlers for DEL and ENTER.</p> <p>For my application, I popup a new window with a textbox, the desired keyboard (alpha, numeric, both, etc), a helpful sentence prompting the user for input and a placeholder showing the desired format.</p> <p>It works really well, and gives us complete control over the user experience.</p> <pre><code>private void key_Click(object sender, RoutedEventArgs e) { _activeControl.SelectedText = (string)((Control)sender).Tag; _activeControl.CaretIndex += _activeControl.SelectedText.Length; _activeControl.SelectionLength = 0; _activeControl.Focus(); } private void btnDEL_Click(object sender, RoutedEventArgs e) { var ci = _activeControl.CaretIndex; if (ci &gt; 1) { _activeControl.Text = _activeControl.Text.Remove( _activeControl.CaretIndex - 1, 1); _activeControl.SelectionStart = ci - 1; } else if (_activeControl.Text.Length &gt; 0) { _activeControl.Text = _activeControl.Text.Remove(0, 1); } _activeControl.Focus(); } private void btnEnter_Click(object sender, RoutedEventArgs e) { // Raise an event here, signalling your application // to validate and move to the next field } </code></pre>

    1. COThank you for your contribution. I did not choose to develop a keyboard myself, but accepted the osk.exe limitations. Your solutions seems nice though!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
