[英]c# access and update datagridview data from another user control
[英]Update datagridview with data from another form (C#)
我在嘗試找出如何在C#中更新datagridview時遇到問題。 我有兩種形式(Form1:使用datagridview / Form2:使用文本框和“保存”按鈕。)
我使用datagridview上的doubleclick函數打開Form2,並顯示所選行的詳細信息。
private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
{
if (dataGridView1.CurrentRow != null)
{
WCustomer row = dataGridView1.CurrentRow.DataBoundItem as WCustomer;
CustomerDetail c1 = new CustomerDetail(_Proxy, row.CustomerID);
c1.CompanyName = dataGridView1.CurrentRow.Cells[1].Value.ToString();
c1.ContactName = dataGridView1.CurrentRow.Cells[2].Value.ToString();
c1.ContactTitle = dataGridView1.CurrentRow.Cells[3].Value.ToString();
c1.Address = dataGridView1.CurrentRow.Cells[4].Value.ToString();
c1.City = dataGridView1.CurrentRow.Cells[5].Value.ToString();
c1.Region = dataGridView1.CurrentRow.Cells[6].Value.ToString();
c1.PostalCode = dataGridView1.CurrentRow.Cells[7].Value.ToString();
c1.Country = dataGridView1.CurrentRow.Cells[8].Value.ToString();
c1.Phone = dataGridView1.CurrentRow.Cells[9].Value.ToString();
c1.Fax = dataGridView1.CurrentRow.Cells[10].Value.ToString();
c1.passDgvValueToCustomerDetail();
c1.Show();
}
else
{
MessageBox.Show("No selected row!");
}
}
要將數據從gridview導入到第二種形式的文本框中,我使用了以下代碼:
public void passDgvValueToCustomerDetail()
{
txtCompanyName.Text = CompanyName;
txtContactName.Text = ContactName;
txtContactTitle.Text = ContactTitle;
txtAddress.Text = Address;
txtCity.Text = City;
txtRegion.Text = Region;
txtPostalCode.Text = PostalCode;
txtCountry.Text = Country;
txtPhone.Text = Phone;
txtFax.Text = Fax;
}
現在,如何通過單擊“保存”后用在第二個表單中更改的地址替換它來更新datagridview中的地址?
已經感謝您的回答。
如果從數據庫表填充了datagridview,那么您必須更新該表並將其綁定到datagridview一次,再單擊“保存”。
