When passing variable from one page to another
To avoid the user messing around with the URL parameter Values
Is it best to ...
1) pass the variable via session
2) pass the variable in the URL along with a signature
Looking for advice on passing variables from page to page without using QueryString. The web crawlers such as google get caught up on the querystrings found in a URL. I'm trying to get away from using it. Is there another suggested method for passing the variables? I've thought about using session variables, but this is just for simply passing the variable from page to page and they won't always be the same.
On another note, I can't do it using forms. I'm using a master page with a form embedded in the master page and also the content pages. Unless microsoft updated it so you can multiple forms on one page.
I need to force SSL when going to the final checkout page (for example from default.aspx to checkout.aspx).
I need to pass variables to this check out page and tried to use server.transfer(https://www.mydomain.com/checkout.aspx). I then use previous page .Fincontrol to read text box and label name to this check out page. If I only do the server.transfer("~/checkout.aspx") then my I can read all vakues of my controls from the passing default.aspx page.
But when I force https:// then I cannot read the control values from default.aspx page.
Please give me some tips on how to get control values to the https:// destination page or if you have another tips on how to do it the right way, please let me know.
I have this sub in a class modulePublic Shared RunMySub(ByVal P as Page) 'I need page ref in the class sub to clear cache like
P.Cache.Remove("MyCache")
end sub
When I call this sub 'RunMySub' from a page, it works fine, ok, great !BUT now I need to run it from another class module...so I did this
Dim mpage As New Page
RunMySub(mpage)
mpage = Nothing
I get the error : Cache not available...How can I pass a page from another class module , thats not a page, or some how manage cache functions on a class module without pass the page varible ???
want to use the value of a variable on to the other page, what i am supposed to do for that.i am novice at asp.net
View 8 RepliesI wanted to know if we can pass values from Parent page (in this case from Default.aspx page) to the user control and maintain those values on subsequent "Add/Load" of user control.
So in short, if I click the "Add" button it loads my "webusercontrol" and also I am able to pass my default.aspx dropdownlist value to this dynamically loaded user control and assign it to a "Label or Textbox" which resides in my "webusercontrol", now the problem is that the value doesn't persists! What I meant is , when I click "Add" button again the "webusercontrol" gets loaded again perfectly but now all my "Label's" in webusercontrol has the new selected value from the default.aspx dropdownlist.
So say for instance I have a Dropdownlist in Default.aspx page with Values "Apple, BlackBerry, Nokia" and initial value to be passed is "Apple", I click the "Add" button, now my "Label" inside webusercontrol has the value "Apple", perfect! Next when I click "Add" button again and select a different value to be passed this time say "BlackBerry" now I have 2 webusercontrol loaded on the page, so that means I have 2 "Labels" with different ID's, but now my first Label initially had the value "Apple" because that's what I had passed and now when I passed the value "Blackberry" both the labels of my webusercontrol has the value "BlackBerry" instead of one being "Apple" and another "BlackBerry"
Is there a way to resolve this issue? may be Dictionary List?
Passing Variable from page to page using ASP.NET (C#) without using QueryString
The difference in my case is that the request is coming from a different website (in java) to my website (in asp.net). I do not want the variable to appear in url.
To explain my scenario, we are making a webpage(plugin), which can be called from any other website. To authenticate request, i am looking for a mechanism when other website will pass id & auth-key to my page. This i can use to authenticate the request. I do not want these variable to be visible.
I have a web page that contains a GridView which the user is allowed to "Edit", "Delete" and "Select" rows. What I'm trying to accomplish is when a user clicks on "Edit", they are redirected to another web page that contains a DetailsView of the record they selected from the GridView (previous page). How do I make the association?

I'm trying to use hyperlink fields in my gridview to pass certain values into another page using querystrings. On the next page I've put 'labels' that should be populated with data from the gridview, however nothing happens. This is my gridview code:
"<asp:GridView ID="GridViewGuitars" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSourceGuitars" DataKeyNames="ProductID" BorderColor="White">
<Columns>
<asp:BoundField DataField="ProductID" HeaderText="ProductID"
SortExpression="ProductID" InsertVisible="False" ReadOnly="True"
Visible="False" />

And this is the code behind file on the landing page:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
Dim ProdID As String = Request.QueryString("ProductID")
Dim ProdName As String = Request.QueryString("Prod_Name")
Dim ProdPrice As String = Request.QueryString("Prod_Price")
Dim ProdStock As String = Request.QueryString("Prod_Instock")
Dim ProdDescrip As String = Request.QueryString("Prod_Descrip")

So to pretty much make this short and sweet, I have a page variable defined outside of all my methods and functions called buttonpressed. It is used to keep track of which button has been pressed on the app. For example, in the onclick event of my Edit button there is a line:
buttonpressed = "Edit"
I use this to decide what kind of query to perform to my database. My problem is whenever I hit my save button(which uses that buttonpressed value in an if statement to decide what query to perform), the variable value just magically disappears.
I tracked the value to make sure that it is being changed and store correctly based on my add, edit, and delete buttons. As soon as I hit my save button, the value of that variable goes blank.
I have this function:
[System.Web.Services.WebMethod]
public static string EditPage(string nodeID)[code]....
in my Web Form but When I try to reference their IDs they don't auto complete and can't be found.
