How do I push the updated Gridview to Database?

I am trying to make a windows form application in C#. I was trying to delete a particular row in Gridview and push the changes into the database. This delete does remove the row. All I want to do is push this updated gridview into the database.

privatevoid dataGridView1_CellContentClick(object sender,DataGridViewCellEventArgs e){string ind = e.RowIndex.ToString();int myint =int.Parse(ind);
            dataGridView1.Rows.Remove(dataGridView1.Rows[myint]);

         }

This is my code for Displaying the Database. 

using (SqlConnectionMyConn=newSqlConnection("Data Source=LENOVO\\SQLEXPRESS;Integrated Security=SSPI;Initial Catalog=SampleData")){string query ="SELECT * from dbo. userpass";SqlCommand cmd =newSqlCommand(query,MyConn);try{SqlDataAdapter sda =newSqlDataAdapter();
                sda.SelectCommand= cmd;DataTable dbdataset =newDataTable();
                sda.Fill(dbdataset);BindingSource bSource =newBindingSource();
                bSource.DataSource= dbdataset;
                dataGridView1.DataSource= bSource;
                sda.Update(dbdataset);}catch{}}
