TextBox readonly “on/off” between “double click and lost focus events” in wpf

Jayden Bell445824-Sep-2013

I have a control like below xaml with Read only enabled.

          <TextBox  Text="{Binding Name,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}"  Background="Transparent" IsReadOnly="True" BorderThickness="0" TextWrapping="Wrap" >  

Now when i double click this text box , i should be able to enter texts. that is my readonly should become false

If i move to another item in the window other than this text box , then i my text box should become readonly again.

I am trying in WPF Trigget. but not getting the right hint . Can anyone help me here ?

Hi Jayden,

You can make this with 2 events, MouseDoubleClick and LostFocus

<Grid>
    <TextBox
IsReadOnly="True"
            
MouseDoubleClick="TextBoMouseDoubleClick"
            
LostFocus="TextBoLostFocus"/>
</Grid>

In you procedural code:

private void TextBoMouseDoubleClick(object sender,MouseButtonEventArgs e)
{
    TextBox textBox =sender as TextBox;
    textBox.IsReadOnly= false;
   
//textBox.CaretIndex = textBox.Text.Count();
    textBox.SelectAll();
}
private void TextBoLostFocus(object sender,RoutedEventArgs e)
{
    TextBox textBox =sender as TextBox;
    textBox.IsReadOnly= true;
}
