Database Updates From DatagridView


A DataGridView control can be used to display data from a database. A table can be displayed from a database in a DataGridView, using the DataAdapter class and data logic. You can easily update a database from a DataGridView.


Step 1

Create a Windows Forms Application Project, and place a DataGridView on the form.
Step 2

Click on the pin button on right-up side of DataGridView and click add project DataSource. And follow these simple steps.

  • Choose DataSourceType Database
  • New Connection, Make Connection
  • Select Table and Column names
  • Finish



Step 3

Your DataSet now has been created. You can see it from the Solution Explorer.


Step 4

See the properties of the Adapter on DataSet, whether it has a query for updating or not. If not then add an update query.


Step 5

A line is automatically generated, when you bind the DataGridView to the dataset. As:

private void testGrid_Load(object sender, EventArgs e)
// TODO: This line of code loads data into the 'gridTestDataSet.Emp' table. You can move, or remove it, as needed.

On Click Event of Update button

private void button3_Click(object sender, EventArgs e)
//Update button update dataset after insertion,upadtion or deletion
     DialogResult dr = MessageBox.Show("Are you sure to save Changes", "Message", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Information);
     if (dr == DialogResult.Yes)
          MessageBox.Show("Record Updated");

To delete, select the rows and then press the Delete key and click the update button; the rows will be deleted. All your insertions, updates, and deletions will be effected by the single button.
