Why are some textboxes not accepting Control + A shortcut to select all by default
.net-2.0, c#, select, textbox
Solution
You might be looking for the ShortcutsEnabled property. Setting it to `true` would allow your text boxes to implement the Ctrl+A shortcut (among others). From the documentation:
Use the `ShortcutsEnabled` property to enable or disable the following shortcut key combinations:
CTRL+Z
CTRL+E
CTRL+C
CTRL+Y
CTRL+X
CTRL+BACKSPACE
CTRL+V
CTRL+DELETE
CTRL+A
SHIFT+DELETE
CTRL+L
SHIFT+INSERT
CTRL+R
However, the documentation states:
The TextBox control does not support the CTRL+A shortcut key when the Multiline property value is true.
You will probably have to use another subclass of `TextBoxBase`, such as RichTextBox, for that to work.
Problem
I have found a few textboxes here and there in my program that accepts Control+A shortcut to select the entire text "by default" with "no coding". I don't know what additional information I have to give here to enable it for all of them, as I find absolutely no difference between these textboxes. They are all simple dragged and dropped textboxes. Note: I'm not talking about this piece of code: ``` if (e.Control && e.KeyCode == Keys.A) { textBox1.SelectAll(); } ``` I want selection by default... or is there anyway to change textbox property so that textboxes accept all default windows shortcuts? Everything else (`Control + Z`, `Control + X`, `Control + C`, `Control + V`) works by default! Why not `Control + A`? Update: The text boxes that accepted `Ctrl+A` by default were masked textboxes, not the regular one. And at that point I was with .NET 2.0. But I guess the original problem was something else, as I can see `Ctrl+A` working fine by default in .NET 2.0 code.
