I'm getting the time limit from the database and then start counting down the clock.

This is my code under script tag inside aspx file

var CDTimer1 = new CountDownTimer(<%# getTimeLimit() %>);

As you can see i have put the function getTimeLimit() that returns an integer , e.g 35.

Here is the function in aspx.vb file
Function getTimelimit() As Integer
        Dim drtimeLimit As SqlDataReader
        Dim gValue As clsGetValues

' this here would get the value from the database and keep in the datareader object
        drtimeLimit = gValue.SP_DataReader("sp_TimeLimit", "@ActivityID", "25")
        If drtimeLimit.Read() Then
            Dim temp As String = drtimeLimit("TimeLimit")
            Dim value As Integer
            value = CInt(temp)
            getTimelimit = value
        Else
            drtimeLimit.Close()
            drtimeLimit = Nothing
            getTimelimit = 0
        End If
    End Function

It compiled successfully but doesn't do the needed work. Somehow CDTimer1 variable is set to 0. I don't understand why. I also want to know what is the different between <%# and <%= tag and when to use them


Thanks

<%= is the same like response.write

try to set your timelimit to 10 in your

else

if the CDTimer1 then is set to 10 then the problem is that
drtimeLimit.Read() = false

i don´t know much about asp.net only asp but have a closer look at the read function, perhaps read needs a parameter.
