You can also do using double.TryParse.

You can check your input on submit button as below mentioned ways.

            double m = 0;

            if (double.TryParse(TextBox1.Text, out m) == false)
            {
                MessageBox.Show("Please enter valid Price");
                TextBox1.Focus();
            }
            else
            {
                // Put your code here
            }
