I need the address (below the dropdown) to change as per the name that is selected in the dropdown... (they are all for one user only)...! (i donno why this keeps saying your post seems only code!!!!!!)
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();
}
}
when you are binding data to dropdown list
ddlStatus.DataTextField = "FullName";
ddlStatus.DataValueField = "Id";
onselected index change event
int ID =Convert.Toint32(ddlName.SelectedValue)
by using this ID select only this ID Record from the dataTable and display

I'm trying to insert a record in the table but the problem is in that table have 3 foreign keys. I'll be using dataTable for that but it gives an error 'There is no row position at 0'
There is my code:
try
{
using (var sqlConnection = new Helpers.SqlConnectionHelpers())
{
var connection = sqlConnection.OpenConnection();
command = new SqlCommand("CarSold_Insert", connection);
command.CommandType = CommandType.StoredProcedure;
SqlCommand commandTwo = new SqlCommand("SELECT CarForSaleId, UserId, SalesPersonId FROM CarSold WHERE Price = '" + txtPrice.Text + "'", connection);
DataTable table = new DataTable();
DataSet dataSet = new DataSet();
table.Load(commandTwo.ExecuteReader());
var carForSaleId = table.Rows[0]["CarForSaleId"].ToString();
var userId = table.Rows[0]["UserId"].ToString();
var salesPersonId = table.Rows[0]["SalesPersonId"].ToString();
command.Parameters.AddWithValue("CarForSaleId", carForSaleId);
command.Parameters.AddWithValue("UserId", userId);
command.Parameters.AddWithValue("SalesPersonId", salesPersonId);
command.Parameters.AddWithValue("Price", txtPrice.Text);
command.Parameters.AddWithValue("DateSold", dateSold);
command.Parameters.AddWithValue("MonthlyPaymentDate", monthlyPaymentDate);
command.Parameters.AddWithValue("MonthlyPaymentAmount", txtPaymentAmount.Text);
//connection.Open();
int k = command.ExecuteNonQuery();
command.Parameters.Clear();
if (k != 0)
{
Response.Redirect("~/AdminPanel/CarSold.aspx");
}
else
{
lblAns.Text = "Record Not Inserted into the database";
lblAns.ForeColor = System.Drawing.Color.Red;
}
}
}
catch (Exception ex)
{
lblAns.Text = ex.Message;
}
Since Price column is float you need to write query with query parameter like this:
SqlCommand commandTwo = new SqlCommand("SELECT CarForSaleId, UserId, SalesPersonId FROM CarSold WHERE Price = #Price", connection);
commandTwo.Parameters.AddWithValue("#Price", txtPrice.Text);
The above mentioned command will give return you the carForSaleId, userId, salesPersonId which you will use in the insert command

Below is the code where The four columns("Challan Number","Proposal Number","CTS Number" and "Amount") is obtained from Sql-Database, and the ("Land" and "Ward") values are obtained from respective methods. The values obtaines are correct but still the "ChallanGridview" is not getting populated.
The datarow "dr1" gets populated with the correct required values, but the "ChallanGridview" doesn't shows anything.
public void FillChallanGrid()
{
string query = string.Empty;
string cs = ConfigurationManager.ConnectionStrings["ConStrg"].ConnectionString;
query = CtrlChallenSearch1.GetChallanQuery();
using(SqlConnection con=new SqlConnection(cs))
{
SqlDataAdapter da = new SqlDataAdapter(query,con);
DataSet ds = new DataSet();
da.Fill(ds,"entry");
int x = ds.Tables["entry"].Rows.Count;
DataTable dt = new DataTable();
dt.Columns.Add("Challan Number");
dt.Columns.Add("Proposal Number");
dt.Columns.Add("CTS Number");
dt.Columns.Add("Amount");
dt.Columns.Add("Land");
dt.Columns.Add("Ward");
for(int i=0;i<x;i++)

Its solved, I just deleted the present gridview and added another fresh one,
don't know how and why, but the error was gone.
btw thnks Asif.Ali!
Expert my search function is not working. Not sure where i went wrong.
My code is

Hi problem is solved by binding the grid with button click.
I want to get only single row from multiple rows with same projectname from the datatable.(Eg. if we have two rows with same projectname,the datatable should be loaded with the only one row and neglect the other one.).I have been using webservices which has the datatable.
I want to achieve this functionality using linq.
I have pasted my code for datatable.Pls help me with working code.
[WebMethod]
public DataTable Get()
{
int a = 0;
cmd = con.CreateCommand();
con.Open();
cmd = con.CreateCommand();
cmd.CommandText = " Select PROJECTNAME,COMPANY,PROJECTSTATUS,STARTEDIN,COMPLETEDIN FROM CMPPROJECT WHERE STATUS ='" + a + "'";
using (OracleDataAdapter sda = new OracleDataAdapter())
{
cmd.Connection = con;
sda.SelectCommand = cmd;
using (DataTable dt = new DataTable())
{
dt.TableName = "CMPPROJECT";
sda.Fill(dt);
return dt;
}
}
}
You can create a DataView object which has a method ToTable in which you can pass true to parameter distinct to select distinct rows. But this has no sense to me. I would do this directly in a select query:
DataTable d = new DataTable("CMPPROJECT");
d.Columns.Add("PROJECTNAME");
d.Columns.Add("COMPANY");
d.Rows.Add(1, 1);
d.Rows.Add(1, 1);
d.Rows.Add(2, 2);
d = new DataView(d).ToTable("CMPPROJECT", true, "PROJECTNAME", "COMPANY");
Here is `linq solution:
var select = (from a in d.AsEnumerable()
select new { c1 = a["PROJECTNAME"], c2 = a["COMPANY"] }).Distinct().ToList();
d.Clear();
foreach (var item in select)
d.Rows.Add(item.c1, item.c2);
