Open numeric only keyboard in Windows Phone?
提问by Cippo
How can i set the keyboard to open in number mode or directly open a special numeric keyboard (as in android)??? My goal is to avoid the user to press the little button to toggle letters and numbers everytime before entering the value that may only be a numerical value. I have a textbox that the user needs to edit.Thanks!!!!

InputScope="Number"
TextBox numercicTextBox = new TextBox();
// ...propriétés de la textbox à initialiser + l'ajouter dans le ContentPanel
numercicTextBox.KeyDown += new KeyEventHandler(numercicTextBox_KeyDown);
void numercicTextBox_KeyDown(object sender, KeyEventArgs e)
{
if (System.Text.RegularExpressions.Regex.IsMatch(e.Key.ToString(),"[0-9]"))
e.Handled = false;
else e.Handled = true;
}
