Hi,

how can I make Gridview cell from accepting only one decimal point like I did for Textbox?

C#

private void txtDiscount_KeyPress(object sender, KeyPressEventArgs e)
{
  if (e.KeyChar == '.')
  {
    if (txtDiscount.Text.Contains('.'))
      e.Handled = true;
  }
}

But for the gridview cell it's not working. Can you help me?

For Child Controls in the Gridview we don't have the direct events

so first we have to get the TextBox value like this

TextBox Foottxtboxunitrate = (TextBox)ProjectOnFormGrid.FooterRow.FindControl("Foottxtboxunitrate");

then

C#

Regex amountpattern = new Regex(@"^[0-9]*(\.)?[0-9]{0,1}?$");
 if (amountpattern.IsMatch(Foottxtboxunitrate.Text.Trim()) == false)
        {
 lblError.Text = "Enter valid Rate amount with maximum 1 decimal places. ";
 lblError.Visible = true;
 Foottxtboxunitrate.Focus();
 return;
        }
