Will any one suggest me ……. its urgent……

Thanx in advance……..

with this code I achieve that works ctrol+c ctrol+v and ctrol+x:

void ExtendedTextBox_KeyDown(object sender, KeyEventArgs e)
{
e.Handled = true;

String Value = Keyboard.HandleKeyDown(sender, e);

//if (AcceptTabs && (e.Key == Key.Tab))
//{
// Value = “\t”; // a plain tab is not displayed correctly, so we use multiple spaces…

// Focus();
//}

//Si es una tecla especial (Por aqui tb pasan las de los acentos)
if (Value.Length == 0)
{
//Switch es la forma más eficiente de hacer esto
switch (e.Key)
{
case Key.Delete:
{
e.Handled = false;
break;
}
//Inicio
case Key.Home:
{
e.Handled = false;
break;
}
case Key.PageDown:
{
e.Handled = false;
break;
}
case Key.PageUp:
{
e.Handled = false;
break;
}
case Key.End:
{
e.Handled = false;
break;
}
case Key.Left:
{
e.Handled = false;
break;
}
case Key.Right:
{
e.Handled = false;
break;
}
case Key.Down:
{
e.Handled = false;
break;
}
case Key.Up:
{
e.Handled = false;
break;
}
//Hay que poner esto para que se lancen los eventos del intro
case Key.Enter:
{
e.Handled = false;
break;
}
case Key.Back:
{
e.Handled = false;
break;
}
case Key.Insert:
{
e.Handled = false;
break;
}
case Key.Escape:
{
e.Handled = false;
break;
}
//Necesario
case Key.Space:
{
e.Handled = false;
break;
}
//Necesario para que funcione el TAB
case Key.Tab:
{
e.Handled = false;
break;
}
//Para Ctrl+C Ctrol+V Ctrol+X
//case Key.Ctrl:
// {
// e.Handled = false;
// break;
// }
case Key.C:
{
e.Handled = false;
break;
}
case Key.X:
{
e.Handled = false;
break;
}
case Key.V:
{
e.Handled = false;
break;
}

}

if ((e.Key == Key.Back) && (m_SelectionLength < 1))
m_SelectionIndex–;

if (IsPassword)
{
// handle selection removal of more than one character per time…
if (Text.Length < m_Protected.Length)
{
m_Protected = m_Protected.Substring(0, m_SelectionIndex) +
m_Protected.Substring(m_SelectionIndex + Math.Max(1, m_SelectionLength));

m_SelectionIndex = Math.Min(m_SelectionIndex, Text.Length);
m_SelectionLength = 0;
}
}

return;
}

UpdateText(Value);
}

Practically, i have do the next:

if (Value == “”) and (Key == V) is because the key “V” don’t produce values and is because any other key is pressed.
In this case, e.Handled = false.
And copy, cut and paste perfectly.

Only there are any bug, that the cursor don’t go to the final of the pasted text, it stay at start of the text pasted.

Any suggest Chris??

Thanks

I detect a bug in InternationalTextBox class:

void ExtendedTextBox_TextChanged(object sender, TextChangedEventArgs e)
{
if (m_SelectionIndex < 0)
SelectionStart = 0;
else
SelectionStart = m_SelectionIndex;
}

On TextChanged methos we have to control if m_SelectionIndex is less than zero.
Sometimes fail it, if don’t control.

For Example. Write in TextBox “Hi, my name is Jose” and with the mouse put the cursor in comma and Back(remove) “Hi,”, just then press DELETE and fail.

Regards!!!

Well you changed a significiant part! Now you check whether the OS is NOT mac whereas you previously checked whether the OS is windows.

So I assume that your OS determination provided wrong results…

I have done this:

public InternationalTextBox()
{
if (System.Environment.OSVersion.Platform != PlatformID.MacOSX)
{
KeyDown += new KeyEventHandler(ExtendedTextBox_KeyDown);
KeyUp += new KeyEventHandler(ExtendedTextBox_KeyUp);
TextChanged += new TextChangedEventHandler(ExtendedTextBox_TextChanged);
SelectionChanged += new RoutedEventHandler(ExtendedTextBox_SelectionChanged);

try
{
IsolatedStorageFile File = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream Stream = File.OpenFile(“InternationalTextBox.keyboard.layout”, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);

using (Stream)
{
BinaryReader Reader = new BinaryReader(Stream);
String Selection = Reader.ReadString();

for (int i = 0; i < TextBoxKeyboard.Keyboards.Length; i++)
{
if (TextBoxKeyboard.Keyboards[i].Description.CompareTo(Selection) == 0)
{
m_Keyboard = TextBoxKeyboard.Keyboards[i].CreateInstance();

break;
}
}
}
}
catch
{
m_Keyboard = new US_Keyboard();
}
}
}

Basicly its the same thing i tried the first time. It’s working. maybe there was some gap in my testing.

I prefer this way because it will not implicate breaking changes in the rest of the code.

Thank you for your patient and help.

…

You can make initialization short by using constructors with more parameters like that:

emailTextBox = new InternationalTextBox(true, 150, 110, …);

For XAML you could try to derive a component from “UserControl” and provide the above switch in the constructor, maintaining a “private TextBox Surface;” member which actuallly represents the content of your user control. Then just export all the member you need by prototyping them like:

Color BackgroundColor
{
get{return Surface.BackgroundColor;}
set[Surface.BackgroundColor = value;}
}

Sorry, but i don’t know any other way of using your textbox without manually instanciate a variable of InternationTextBox type, initialize it with the constructor and manually add it to the UI like this:

emailTextBox = new InternationalTextBox();
emailTextBox.Keyboard = new Portuguese_Keyboard();
emailTextBox.AcceptsReturn = true;
emailTextBox.Width = 150;
emailTextBox.Height = 110;
emailTextBox.Margin = new Thickness(5, 5, 0, 5);
emailTextBox.Padding = new Thickness(0, 0, 0, 0);
emailTextBox.HorizontalAlignment = HorizontalAlignment.Left;
emailTextBox.VerticalAlignment = VerticalAlignment.Bottom;
emailTextBox.BorderThickness = new Thickness(0);
emailTextBox.FontSize = 10;

LayoutRoot.Children.Add(emailTextBox);

I have already tried to instanciate it in xaml without any success. That would be wonderfull for me as i could have much less code.

I tried like this, but silverlight explodes and nothing appears:

xmlns:sda=”clr-namespace:SDA.SL.UI”

…

So, what i understood from your tip was to avoid everything in the InternationTextBox constructor while in mac.

Can you please be more specific? As i’m not understanding you.

Thank you,

Best regards,

Nuno

So I don’t see the problem…

If you don’t execute the constructor in mac, my textbox is simply a usual textbox, so it should work!

This is what i have done in the constructor

if (Page.platform == Platform.Windows)
{
KeyDown += new KeyEventHandler(ExtendedTextBox_KeyDown);
KeyUp += new KeyEventHandler(ExtendedTextBox_KeyUp);
TextChanged += new TextChangedEventHandler(ExtendedTextBox_TextChanged);
SelectionChanged += new RoutedEventHandler(ExtendedTextBox_SelectionChanged);

try
{
IsolatedStorageFile File = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream Stream = File.OpenFile(“InternationalTextBox.keyboard.layout”, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);

using (Stream)
{
BinaryReader Reader = new BinaryReader(Stream);
String Selection = Reader.ReadString();

for (int i = 0; i < TextBoxKeyboard.Keyboards.Length; i++)
{
if (TextBoxKeyboard.Keyboards[i].Description.CompareTo(Selection) == 0)
{
m_Keyboard = TextBoxKeyboard.Keyboards[i].CreateInstance();

break;
}
}
}
}
catch
{
m_Keyboard = new US_Keyboard();
}
}

Any thing missing?

Thx,

Nuno
