Winforms TextBox number presentation

Question

I want the TextBox to display numbers with 3 digits and exponentials.

fe 0.123E-08

Is there a Way to do this with normal Winforms TextBoxes?

Answer 1

As I now there is not a native property on Textbox but you can apply the instructions on the links below.

Answer 2

You can use double.ToString() to format the string before setting TextBox.Text .

For example:

double value = 0.00000000123;

string s = value.ToString("#.###E00");
Console.WriteLine(s);

Or just assign to TextBox.Text:

textBox.Text = value.ToString("#.###E00");;
