У меня есть веб-приложение, в котором при загрузке страницы данные об адресе извлекаются из базы данных и отображаются в соответствующих текстовых полях. Однако когда я пытаюсь обновить и сохранить данные, данные не обновляются.
Однако то же самое отлично работает, когда извлечение данных происходит нажатием одной кнопки.
вот код:
public partial class Address : System.Web.UI.Page
{
string global;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
global = Session["ID"].ToString();
System.Data.SqlClient.SqlConnection con = new System.Data.SqlClient.SqlConnection("Server = INLD50045747A\\SQLEXPRESS; Database = MyDatabase;User ID = sa; Password = Welcome1; Trusted_Connection = False;");
//SqlConnection con = new SqlConnection("Data Source=.\\SQLEXPRESS; AttachDbFilename=|DataDirectory|\\MyDatabase.mdf;Integrated Security=True;User Instance=True");
con.Open();
SqlCommand cmd = new SqlCommand("SELECT PermanentAdd,PermanentAdd2, HomePlace, HomeState, HomePin FROM EMPLOYEE_FULLADDRESS_TABLE WHERE EmployeeID = '" + global + "'", con);
SqlDataReader x = cmd.ExecuteReader();
while (x.Read())
{
TextBox1.Text = (string)x["PermanentAdd"];
TextBox1.Enabled = false;
TextBox5.Text = (string)x["PermanentAdd2"];
TextBox5.Enabled = false;
TextBox2.Text = (string)x["HomePlace"];
TextBox2.Enabled = false;
TextBox3.Text = (string)x["HomeState"];
TextBox3.Enabled = false;
State.Items.FindByText(State.SelectedItem.Text).Selected = false;
State.Items.FindByText(TextBox3.Text).Selected = true;
State.Enabled = false;
TextBox4.Text = (string)x["HomePin"];
TextBox4.Enabled = false;
}
x.Close();
con.Close();
}
}
protected void UpdateButton_Click(object sender, EventArgs e)
{
try
{
System.Data.SqlClient.SqlConnection con = new System.Data.SqlClient.SqlConnection("Server = INLD50045747A\\SQLEXPRESS; Database = MyDatabase;User ID = sa; Password = Welcome1; Trusted_Connection = False;");
//System.Data.SqlClient.SqlConnection con = new System.Data.SqlClient.SqlConnection("Data Source=.\\SQLEXPRESS; AttachDbFilename=|DataDirectory|\\MyDatabase.mdf;Integrated Security=True;User Instance=True");
con.Open();
// global = Session["ID"].ToString();
//string insert = "UPDATE EMPLOYEE_FULLADDRESS_TABLE SET PermanentAdd = @PermanentAdd, PermanentAdd2 = @PermanentAdd2, HomePlace = @HomePlace, HomeState= @HomeState, HomePin= @HomePin where EmployeeID = '" + global + "'";
SqlCommand cmd1 = new SqlCommand("UPDATE EMPLOYEE_FULLADDRESS_TABLE SET PermanentAdd = @PermanentAdd, PermanentAdd2 = @PermanentAdd2, HomePlace = @HomePlace, HomeState= @HomeState, HomePin= @HomePin where EmployeeID = '" + global + "'", con);
cmd1.Parameters.AddWithValue("@PermanentAdd", TextBox1.Text);
cmd1.Parameters.AddWithValue("@PermanentAdd2", TextBox5.Text);
cmd1.Parameters.AddWithValue("@HomePlace", TextBox2.Text);
if (State.SelectedItem.Text == "--Select--")
{
State.SelectedItem.Text = TextBox3.Text;
}
cmd1.Parameters.AddWithValue("@HomeState", State.SelectedItem.Text);
cmd1.Parameters.AddWithValue("@HomePin", TextBox4.Text);
cmd1.ExecuteNonQuery();
con.Close();
lblmsg.Text = "DATA Updated Successfully";
lblmsg.ForeColor = System.Drawing.Color.Green;
}
catch (Exception exp)
{
lblmsg.Text = exp.Message;
lblmsg.ForeColor = System.Drawing.Color.Red;
}
}
// static int count = 0;
protected void EditButton_Click(object sender, EventArgs e)
{
TextBox1.Enabled = true;
TextBox2.Enabled = true;
//TextBox3.Enabled = true;
TextBox4.Enabled = true;
TextBox5.Enabled = true;
State.Enabled = true;
}
пожалуйста, помогите.
