Introduction
In this tutorial we will learn how to pass data from one form to another form in Windows Forms applications using C#.
Let's use the following procedure to create a Windows Forms application.
Step 1
In Visual Studio select "File" -> "New" -> "Project..." then select C# Windows Forms Application then click Ok.
![window form application]()
Step 2
Drag and drop a Label and a TextBox from the Toolbox. I created a Form with 3 Labels and a TextBox as shown in the following figure.
![ToolBox]()
Step 3
I have a Name, Fname and Address Label on the form. So I use three global variables. Write the following code in the Form1.cs.
- public static string SetValueForText1 = "";
- public static string SetValueForText2 = "";
- public static string SetValueForText3 = "";
Step 4
Add another Windows Forms form using Project --> Add Windows Form thenn click on Add.
![Windows Form]()
Step 5
After creating the form double-click on the Submit button on the Windows Form1 and write the code:
- private void button1_Click(object sender, EventArgs e)
- {
- SetValueForText1 = textBox1.Text;
- SetValueForText2 = textBox2.Text;
- SetValueForText3 = textBox3.Text;
-
- Form2 frm2 = new Form2();
- frm2.Show();
- }
Step 6
Drag and Drop 3 Labels from the Toolbox onto Form2.

Step 7
Double-click on Form2 and write the code:
- private void Form2_Load(object sender, EventArgs e)
- {
- label1.Text = Form1.SetValueForText1;
- label2.Text = Form1.SetValueForText2;
- label3.Text = Form1.SetValueForText3;
- }
Step 8
Now press F5 to run the application.
Fill in Form1 and click on Submit. The data will pass from Form1 to Form2.
