In this tutorial, I’m going to show you how to create an autonumber in the TextBox in C#.net. This process has the ability to auto generate the number in the TextBox when the button is clicked. It is very useful for the future use, most specially when developing a system.
Let’s get started:
1. Open Microsoft Visual Studio 2008 and create new Windows Form Application for C#. Then, drag a TextBox and Button in the do the Form.
2. After setting up the Form, double click the “click” button to fire the click event handler. Then, put the following code into it.
private void button1_Click(object sender, EventArgs e)
//declare a variable for storing the incremented value into it
//set the formula for the incrementing of a textbox
autonum = autonum + int.Parse(textBox1.Text);
//put the value in the textbox.
textBox1.Text = autonum.ToString();
Description: The number in the TextBox will be incremented by 1 when the button is clicked.
Output in Autonumber in a TextBox:
