Ich erstelle ASP.NET, C# -Anwendung. Wo sind zwei Textfelder bei der Eingabe von Wert Ergebnis wird in Gridview von SQL Server angezeigt. Problem ist, dass, wenn ich Nummer 5 gebe ich 15 Wert, example. Kann jemand einen Hinweis geben?Kann nicht genau Wert von SQL-Datenbank in ASP.NET erhalten
Wie bekomme ich genau den Wert aus der Datenbank, wie in Textbox eingegeben?
Source Code:
SQL-Prozedur
Create table Hall

HallID int,
Name nvarchar(50),
TicketLimit int
)
GO
Create table HallGroup
(
HallID int,
HallGroupID int,

AZ int
)
GO
Create table HallSeat
(
HallGroupID int,
ShowSeatID int,
Color nvarchar(15),
Price int,
SeatRow int,
SeatNumber int,
IsReserved bit

Begin
select * from HallSeat where (SeatNumber like '%' + @searchNumber + '%') and (SeatRow like '%' + @searchRow + '%')
End
Code hinter

SqlConnection result = new SqlConnection(cs);
String search = "Search"; // Paieskos
SqlCommand find = new SqlCommand(search, result);
find.CommandType = CommandType.StoredProcedure;
find.Parameters.Add("@searchRow", SqlDbType.VarChar).Value = TextBoxRow.Text;

result.Open();
SqlDataReader dr;
dr = find.ExecuteReader();
if (dr.HasRows)

dr.Read();
rep_bind();
GridView1.Visible = true;
TextBoxRow.Text = "";
TextBoxNumber.Text = "";
