I have a single webserver using win 2k8 and IIS 7 that is not on a web farm. For one particular page I keep getting one of these 2 errors when any event is executed on the page
Most of the time it is the viewstate error.
This error only happens in Internet Explorer 6 and 7.
I have used firefox and safari and everything works just fine it only happens in IE.
I have a chack box list and a couple of drop down lists on my page as well as a gridview etc.
I tried changing the machine key to no avail so i changed ot back to auto generate
I had read an article where you coudl store viewstate as a session but was not sure how to do that in VB.net
Any ideas how I can correct this?
Thanks
Here are the errors

Viewstate verification failed. Reason: The viewstate supplied failed integrity check.

Forms authentication failed for the request. Reason: The ticket supplied has expired.

One possible cause is that your asp.net pages are not inheriting from System.Web.UI.Page, i had that problem when i converted to .net 3.5, but i've never used IIS7 or win 2k8, so i'm afraid i cant be more help.

I have problems to show images in a datagrid. I was looking for some answer and I found that if I use this code it should be work.
Dim Comm As New OleDbCommand(QPhoto, con.Con)

Conexion.Open()
Dim OledbRead As OleDbDataReader
OledbRead = Comm.ExecuteReader(CommandBehavior.CloseConnection)
Do While (OledbRead.Read)
Response.ContentType = OledbRead.Item("IDArti")
Response.BinaryWrite(OledbRead.Item("Image"))
Loop
con.Con.Close()

But, unfortunatelly it doesn't work. When I try to run this code, it asks me if I want to open or save and the both options don't do anything.
Could you help me?
I have the images in Access database and I want to display them in the datagrid with the information of each row
Please, help me I'm stressed out Confused | :confused:

You need to isolate streaming of an image to a separate handler. Check this out:

I have two web pages , i am navigating from page1 to page2 with a query string . The problem is i don't want to show the query string value in the address bar , it leads to database hacking.
How should i overcome this problem ?

If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

make another page, page a for now, a basic html page with a frameset that loads page 1, make page a the default page on the webserver and all they will ever see is whatever you call page a, but they'll interact with page 1 and when you navigate to page 1 to page 2 the address bar wont change and if you set the frameset up correctly no one will ever notice it. you could also put your querystring values into the session or viewstate and pass them that way.

Use View Source in the browser, and you'll see what id the elements really have.

You can use the ClientID property of a server control to find out what id it will get in the rendered page.

Despite everything, the person most likely to be fooling you next is yourself.

i have a gridview within a scriptmanager and within the gridview i have a templatefield which contains a hyperlink control which when clicked resubmits this page with some query strings attached. see code below:

<asp:TemplateField HeaderText="Order">
                      <ItemTemplate>
                       <asp:HyperLink ID="Hyperlink3" runat="server" NavigateUrl='<%# "default.aspx?SearchType=Wip&CustPO=" &amp; rtrim(DataBinder.Eval(Container, "DataItem.PO#")) & "&StockCode=" & DataBinder.Eval(Container, "DataItem.MStockCode") %>'
                                  Target="_self" Text='<%# DataBinder.Eval(Container, "DataItem.PO#") %> ' ToolTip="Check Work In Progress!">
                         </asp:HyperLink>
                      </ItemTemplate>
                      </asp:TemplateField>

How can i catch this event when the user clicks the hyperlink from the gridview.

obviously page.ispostback or ScriptManager1.IsInAsyncPostBack do not catch this event. ? any ideas people - ajax newbie so forgive my ignorance
