To create DataGridView first of all we need to insert DataGridView tool from

toolbox.

Now, once the DataGrid is inserted we need to display data in it. To display data we

need to set its data source data table.

Example

           try
            {
            string strConnection= "Server=abc\\SQLEXPRESs;Database=Employee;Trusted_Connection=True";
            SqlConnection con = new SqlConnection(strConnection);
            con.Open();
            SqlDataAdapter da = new SqlDataAdapter("select * from employee", con);
            DataSet ds = new DataSet();
            da.Fill(ds, "Employee");
            DataTable dt = ds.Tables["Employee"];
            dgRecord.DataSource= dt;
          //setting datasource of datagrid to a table of database ‘employee’
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }

 
Here dgRecord is the name of DataGrid.
