Hi jsshivalik,

According to your description, I wrote a demo for you as reference.

The ToString() method returns a string "("#,##0.00")" for this object.

Note: You need to set the property of the TextBox control AutoPostBack="true". Because its value need interact with the server.

The code:

<asp:TextBox ID="TextBox1" runat="server" OnTextChanged="TextBox1_TextChanged" AutoPostBack="true"></asp:TextBox>

protected void TextBox1_TextChanged(object sender, EventArgs e)
        {
            if (!string.IsNullOrEmpty(TextBox1.Text.ToString()))
            {
                String Input = TextBox1.Text;
                TextBox1.Text=Convert.ToDecimal(Input).ToString("#,##0.00");
            }

        }

The result:

Best regards,

Sam

Hi, jsshivalik

You can use the minimumFractionDigits option of the toLocaleString function.

// result 3,000.00
Number(parseFloat(3000).toFixed(2)).toLocaleString('en', {
    minimumFractionDigits: 2
});

You can refer below link for same. you will be more confident
