Limit OR Restrict Number of Characters in Textbox C#.Net In windows Application

In this article I will show you how you can limit or restrict number of characters in textbox c#.net in windows application.

Some of my previous articles are as follows: AutoSuggest DropDownList In Windows Application Using C#.Net, Random Character and String Generation Using C#.Net, Windows Application and Linq, Strong Random String Password Generation Using C#.Net, Login Form By UserType OR User Role In Windows Application In C#.Net , Linq, Display Message With Warning icon in Windows Application Using C#.Net, Stylish ToolStrip Button Control With Image and Text Control In Windows Application Using C#.Net.

So for this article first we will create a new windows application create the below form.

Now add the below code into the form.

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace WindowsFormsApplication1 {     public partial class Form1 : Form     {         public Form1()         {             InitializeComponent();         }         private void textBox1_TextChanged(object sender, EventArgs e)         {             if (textBox1.Text.Length <= 10)             {                 label1.Text = "Total No of Characters : " + textBox1.Text.Length;             }         }         private void Form1_Load(object sender, EventArgs e)         {             textBox1.MaxLength = 10;         }     } }

On page load I have assign the max length of the textbox. And on textbox change I have calculated the total no of character added in the textbox.

Now we have run the application and check the output.
