Use one button for both save and edit on Gridview in c#

Question

I have a scenario where I can save the name and phone number. but now I want to use my "Save" button as update button from clicking on grid view data.

Also after clicking on gridview data "save" button automatically change as "Update" I want to know if there is any event or something to make it.

        SqlDataAdapter data;
        DataSet ds;
        int num = 0;
        int i;

                if (cmd.ExecuteNonQuery() > 0 && saveButton.Text == "Save")

            userTextBox.Text = userdataGridView1.CurrentRow.Cells["Id"].Value.ToString();
            nameTextBox.Text = userdataGridView1.CurrentRow.Cells["Name"].Value.ToString();
            phoneNumberTextBox.Text = userdataGridView1.CurrentRow.Cells["PhoneNumber"].Value.ToString();
        }
    }

Answer 1

Or you can create an Update button then place it behind the Save button. Add a RowHeaderMouseClick event on your dataGridView that will place the values from the highlighted cells to the textboxes.

private void dataGridView1_RowHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
    {
        foreach (DataGridViewRow row in dataGridView1.SelectedRows)
        {
            //assuming the datagrid displays ID in the 1st cell, Cells[0]
           string name = row.Cells[1].Value.ToString();
           string phoneNum = row.Cells[2].Value.ToString();
        }
        textBox2.Text = name;
        textBox3.Text = phoneNum;
        updateButton.BringToFront();
        saveButton.SendToBack(); //optional
    }

Then, add these lines to your Update button Click event to bring the Save button in front again.

saveButton.BringToFront();
updateButton.SendToBack();

Make two Event for grid view.

1)Got Focus

2)Lost Focus

1)On GotFocus Event Change it to Update and maintain mode to insert and update

2)On Lost Focus Change it to Save.
