Hi Everyone,
Im using ASP.NET and SQL Server. I have Insert , delete data working well. but if i update a particular record it just all the records are updated with the same value.

for example if i have 3 records with 3 different values, if i display the second record, and edit it, and update it. then all the 3 values are updated with the same value what i have entered. i donno what is the error in my code. can anyone enlighten me?

here is the code,

Imports System

        con = New SqlConnection("Data Source=ACER;Initial Catalog=preethi;Integrated Security=True")
        con.Open()
    End Sub

    Private Sub fillcontrols()
         TextBox1.Text = data.Tables(0).Rows(0).Item(0)
        TextBox2.Text = data.Tables(0).Rows(0).Item(1)
        TextBox3.Text = data.Tables(0).Rows(0).Item(2)

            clearcontrols()

        Catch ex As Exception
            Response.Write(ex.Message)
        End Try

        Try
            
            selct = "select * from cooldrinks"
            adp = New SqlDataAdapter(selct, con)
            data = New DataSet3()
            adp.Fill(data, "cooldrinks")
            fillcontrols()

        Catch ex As Exception
            Response.Write(ex.Message)
        End Try
    End Sub

It is so obvious that you dont have any where condition in the update statement.

uptext = "update cooldrinks set drinkname = @drinkname ,color = @color, price = @price" --> You need to add the where clause here.

hi,

this is the code i have given.....

uptext = "update cooldrinks set drinkname = @drinkname ,color = @color, price = @price where price = " & TextBox3.Text & " "

You need to check your records to see the prices are same for all records.
