我需要根据下拉列表中选择的名称更改地址（下拉列表下方）...（它们都仅供一个用户使用）...！（我不知道为什么这一直说你的帖子似乎只是代码！！！！！！）
public DataSet BindDropDownListToAUserAddress2()
{
UserFunctions objGetSession = new UserFunctions();
string strSession = objGetSession.GetEmailFromSession();
DataSet dsUserAddress = new DataSet();
SqlConnection con = new SqlConnection(System.Configuration.ConfigurationManager.AppSettings["ConnectionString"]);
con.Open();
string strQuery = "(SELECT FirstName +' '+ LastName as FullName, * FROM AUserAddress inner join AState on AUserAddress.State_ID = AState.ID inner join ACountry on AUserAddress.Country_ID = ACountry.ID inner join AUser on AUserAddress.AUser_ID=AUser.ID where AUser.Email='" + strSession + "')";
SqlCommand cmd = new SqlCommand(strQuery, con);
using (SqlDataAdapter da = new SqlDataAdapter(cmd))
da.Fill(dsUserAddress, "AUserAddress");
con.Close();
return dsUserAddress;
}
protected void ddlName_SelectedIndexChanged(object sender, EventArgs e)
{
DataSet dsUserAddress = objBindDDL.BindDropDownListToAUserAddress2();
string strSession = objGetSession.GetEmailFromSession();
ddlName.SelectedValue = "FullName";
if (objBindDDL.BindDropDownListToAUserAddress2() != null && objBindDDL.BindDropDownListToAUserAddress2().Tables.Count > 0)
{
lblDisplayFirstName.Text = dsUserAddress.Tables["AUserAddress"].Rows[0]["FirstName"].ToString();
lblDisplayLastName.Text = dsUserAddress.Tables["AUserAddress"].Rows[0]["LastName"].ToString();
lblDisplayAddressLine1.Text = dsUserAddress.Tables["AUserAddress"].Rows[0]["AddressLine1"].ToString();
lblDisplayAddressLine2.Text = dsUserAddress.Tables["AUserAddress"].Rows[0]["AddressLine2"].ToString();
lblDisplayAddressLine3.Text = dsUserAddress.Tables["AUserAddress"].Rows[0]["AddressLine3"].ToString();
lblDisplayCity.Text = dsUserAddress.Tables["AUserAddress"].Rows[0]["City"].ToString();
lblDisplayState.Text = dsUserAddress.Tables["AUserAddress"].Rows[0]["StateName"].ToString();
lblDisplayCountry.Text = dsUserAddress.Tables["AUserAddress"].Rows[0]["CountryName"].ToString();
lblDisplayPostalCode.Text = dsUserAddress.Tables["AUserAddress"].Rows[0]["PostalCode"].ToString();
}
}
