How to select Numeric UpDown value programmatically in Winforms?

Question

I want to select the available value within the numeric up/down control using c#

and in general if we double click within the control then we get the following(the entire text gets selected colored Blue in BG)

Now my question is How do I achieve this pro-grammatically??

My trails so far :

Focus();

Select();

this doesn't seem to work, any help on this regard would be much appreciated, Thanks..:)

Answer 1

Select has an overload that takes two int, one for selection start, one for selection length:

myNumericUpDown.Select(0, myNumericUpDown.Text.Length);

Answer 2

Do you not just want the .Value property of the control? Or are you trying to get it exactly the way it is formatted in the textbox?

Answer 3

You can get to the TextBox portion of the control through a trick, use the Controls property. Like this:

    var box = (TextBox)numericUpDown1.Controls[1];
    box.SelectAll();
    box.Focus();

This would normally be a bit fragile, but it is 99.9% guaranteed that NumericUpDown is never going to change.
