Question

I am displaying Mac Address in a WPF application.
I want that mac address to be selectable to be copy/paste, so I am using ReadOnly TextBox

When the user double click I want to select the whole MacAddress

The default behavior by the WPF and Windows, is by double click select part of the number between colons
so when the mac address is : 00:55:66:77:99

and the user double click, only one part of the mac address (like 55) being selected
Is there a way without a code to make the selection for the whole content for textbox

or maybe I should not use textbox?

Thanks

On MouseDoubleClick event of textbox you can call SelectAll() method of textbox to select al the text inside it.

void textBox_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    (sender as TextBox).SelectAll();
}
