Hi,
I have a textbox. How can I make a textbox to accept only two digits after the decimal, although in the database, the value contains more than two digits after the decimal?

If I enter 5, it should take as 5.00.
Similarly:
for 5.1 it should take as 5.10
for 5.1234 it should take as 5.12

Hope you'll suggest me a solution.

Solution 1

If you are asking for Windows forms apps.

Inside TextBox Leave Event

C#

private void textBox1_Leave(object sender, System.EventArgs e)
{
    TextBox1.Text = double.Parse(TextBox1.Text).ToString("f2");

}

Will convert it to a string. Once he saves it to the database, it'll contain more than the specified two decimal numbers.

@Eddy : for that he need to manually setup decimal points in DB for particular column

Solution 2

If it's a decimal in the database, then it'll simply be a fractional number without any formatting applied. If you only want to see two decimals, then cut off all other decimals when retrieving the value and before displaying it.
