One of the main features of Web pages is to offer forms that end users can use to submit their information for collection. The TextBox server control is one of the most used controls in this space. As its name suggests, the control provides a text box on the form that enables the end user to input text. This server control is an input Text Field on Webpage where the user can enter Text.

Important Properties:

The Focus() method enables you to dynamically place the end user's cursor in an appointed form element(not just the TextBox control, but in any of the server controls derived from the webcontrol class)

Example:

protected void page_Load(object sender, EventArgs e)

{

TextBox1.Focus();
