Hi!

Can you help me produce a text when a read button is clicked? Here is my code. Hope you could help me with this.

using System;
using System.Threading;
using Microsoft.SPOT;
using Microsoft.SPOT.Input;
using GHIElectronics.NETMF.Glide;
using GHIElectronics.NETMF.Glide.Display;
using GHIElectronics.NETMF.Glide.UI;

namespace Test
{
    public class Program
    {
        // This will hold the main window.
        static Window window;

        public static void Main()
        {
            // Load the window

            string xml;
            xml = "<Glide Version=\"" + Glide.Version + "\">";

            // Resize any loaded Window to the LCD's size.

            GlideTouch.Initialize();

            // Initialize the window.
            InitWin();

            // Assigning a window to MainWindow flushes it to the screen.
            // This also starts event handling on the window.
            Glide.MainWindow = window;


            Thread.Sleep(-1);
        }

        static void InitWin()
        {
            TextBlock freq = (TextBlock)window.GetChildByName("Frequency");
            TextBlock epc = (TextBlock)window.GetChildByName("EPC");
            TextBlock rssi = (TextBlock)window.GetChildByName("RSSI");
            TextBlock phase = (TextBlock)window.GetChildByName("Phase");
            TextBlock tagsdet = (TextBlock)window.GetChildByName("tagsdet");

            // Get the Button
            Button btn = (Button)window.GetChildByName("btn");
            Button stopbtn = (Button)window.GetChildByName("stopbtn");
            // Listen for tap events
            btn.TapEvent += new OnTap(btn_TapEvent);
        }

        // Handle tap events
        static void btn_TapEvent(object sender)
        {
            TextBlock text1 = (TextBlock)window.GetChildByName("text1");
            text1.Text = "30003hjlasdjf";
            Thread.Sleep(1000);
            TextBox text2 = (TextBox)window.GetChildByName("text2");
            TextBox text3 = (TextBox)window.GetChildByName("text3");
            TextBox text4 = (TextBox)window.GetChildByName("text4");
            TextBox text5 = (TextBox)window.GetChildByName("text5");
            Thread.Sleep(1);
        }

    }
}

Apparently, the “sample text (text1.Text)” doesn’t appear if i click the button. what should I do? :frowning: Also, I would like to ask for the difference of TextBlock and TextBox. Thank you again! :slight_smile:

Here’s the answer to your last question :slight_smile:

TextBlock = a block of text.

TextBox = a box with text in it.

ie a Block is just a bounded area, whereas a Box has a visible bounded margin

Next step for me would be to try a simple example. A button and a text box.

Does your button handler ever get invoked when you click? Use breakpoints to check.

You need to call Invalidate() on each of the text blocks to get them to update after you update them with new text.

eg.

TextBlock text1 = (TextBlock)window.GetChildByName("text1");
text1.Text = "30003hjlasdjf";
text1.Invalidate();

This will cause it to update on the display.
