i got to know why my page was crashing.. thanks

hi,

i m facing problem in gridview updating. I m using sqldatasource to select and update the record.
In select of sqldatasource i m passing three parameter and in update i m passing 4 parameter. when i run my program, the select in sqldatasource works perfect. but when i update that record...its throws error...
" Function or stored procedure has too many arguments passed". Even though i m getting this error and my page crashes...i m still able to update the record, this i noticed when i stop the program after webpage crash and then run the program again. but i dont want my webpage to crash.

Here is my ASPX file code...

thanks Jamie!

i have created drop downdownlist and i m binding it with the testnames in the database.

Private Function load_sptestreqtestnameddl()

    Dim Adptr As New SqlDataAdapter
    Dim Pkgddldt As New DataSet

    '##################     FOR CONNECTION  ################

    Dim MySearchCon As DbConnection = providerFactory.CreateConnection()
    MySearchCon.ConnectionString = connectionString.ConnectionString

    '###################  END OF CONNECTION #################

    Dim str As String = Nothing
    str = ("SELECT test\_id, test\_name FROM TestName")

    Adptr = New SqlDataAdapter(str, MySearchCon)
    Adptr.Fill(Pkgddldt)

    sptestreqtestnameddl.DataSource = Pkgddldt
    sptestreqtestnameddl.DataSource = Pkgddldt.Tables(0)
    sptestreqtestnameddl.DataTextField = Pkgddldt.Tables(0).Columns("test\_name").ColumnName.ToString
    sptestreqtestnameddl.DataValueField = Pkgddldt.Tables(0).Columns("test\_id").ColumnName.ToString

sptestreqtestnameddl.DataBind()
Return 0
End sub

the code shows me following error....this exactly same code works perfect in other webforms. 'sptestreqtestnameddl' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value

hi. i have created a page having menu and multiview. this i used to create a tabs and on clicking on tab raises an onMenuItemClick event. this event i have placed it in vb script. when i run this page it works perfectly...and clicking on tabs shows me the content of that tab. but when i connect this page with masterpage and instead of writing script in the webpage...i wrote it in .vb codefile and tried to run the page...but surprisingly on clicking on tab takes me to home pages which is my default.aspx. when i put breakpoints on menuclick event in .vb codefile and then tried to debug the page it doesnt raise any event on tab click because it doesnt reaches the breakpoint. dont know what wrong with the code. here are is the .aspx page not linked to masterpage

    If e.Item.Value = "0" Then
        STDmultiview.ActiveViewIndex = "0"
    Else
        STDmultiview.ActiveViewIndex = "1"

runat=server attribute indicates that the element should be treated as a server control And page can have one or more forms in page. How many form tags with runat=server is allowed? --> this thing i dont know. but form requires a runat attributes when using GridView Plz give briefing on this and solution to the problem.. thank u..

please, tell me if u need a code .

here is the gridview page file code: <%@ Page Language="vb" AutoEventWireup="false" CodeBehind="ScheduleList.aspx.vb" Inherits="PATHOLOGY._Default" %>

hi, i am having a page with gridview and i want to open the page in master page...so to do this i removed the runat server attribute from the page and on the link button of the master page i referred the page with gridview ...but showed me an error " form with gridview must have runat=server attribute". when i put this attribute...and try to open in master page, the page with gridview loads leaving the masterpage....i figured out that when my masterpage form and gridview page form tag both have runat= server attribute then the gridview page will be loaded leaving the masterpage.
