Dears
Why my application is not rendering the textbox txtmatricula? It´s about thread?
protected void btnOK_TapEvent(object sender)
{
txtMatricula = (TextBox)window.GetChildByName(“txtMatricula”);
txtMatricula.Text = “111111111111”;
}
Have you tried Invalidate as was suggested in the other thread?
A textbox should invalidate itself after changing of text property…
Is it rendered without a value before tapping the OK button?
Or is it just not showing the value “111111111111” after tapping OK?
I should have read everything, and the other thread too 
Yeah, Invalidate should do the trick…
