C# DataGridView – Add Text From Textbox to DataGridView On Button Click – Programming, Pseudocode Example, C# Programming Example

In this tutorial I’ll show you how to add data from textbox into DataGridView. Firstly I designed the Windows Form Application as following the picture.

I added three textboxes, a button and a gridview. I named textboxs as txtName, txtLastName, txtAge. Also I named the button and the gridview as btnAdd, dataGridViewList.

If you finish the design just double click the btnAdd (button). Now I will appreciate any ideas or solutions on how can we possibly get the values from textboxes on button click

I defined the names of columns in Form1() metod. Form1 method is constructor method of this class and project.

From1() Method:

public Form1()

{

InitializeComponent();

//Construct the datagrid

dataGridViewList.ColumnCount = 3;

dataGridViewList.Columns[0].Name = "Name";

dataGridViewList.Columns[1].Name = "LastName";

dataGridViewList.Columns[2].Name = "Age";

//for equel width

dataGridViewList.Columns[0].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;

dataGridViewList.Columns[1].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;

dataGridViewList.Columns[2].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;

}

btnAdd Click:

private void btnAdd_Click(object sender, EventArgs e)

{

addRow(txtName.Text,txtLastName.Text,txtAge.Text); //alternative 1

dataGridViewList.Rows.Add(txtName.Text, txtLastName.Text, txtAge.Text); //alternative 2

}

And AddRow Method: (You may aslo add in the btnAdd)

private void addRow(string name, string lastname, string age)

{

String[] row = { name, lastname, age };

dataGridViewList.Rows.Add(row);

}
