I have a aspx page and there is a web user control that must load dynamically with the data related to the aspx page....
ok so I want to use a querystring and pass it to the web user control.....how do I do this?
then also how do I pass a querystring from a web user control back to a aspx page?
This is a question I always had...and therefore never actually started to use the web user control
trying to pass a guid value to querystring - it should take the guid value from one page to another. i get an error: value cannot be null, parameter name: g. so my guid value is not being pass to my second page. below is code:
Page one:
static Guid g = Guid.Empty;
public static string userID = g.ToString();
string userName = string.Empty;
[code]...
Again, I am wondering why there is no one asking this kind of question. And may be my idea is wrong. Let's see the code:
<uc1:drilldown ID="drilldown1" runat="server" sType="F.W" rID='<%=request.querystring("r") %>' />
After it passed into my property in user control, the value is <%=request.querystring("r") %>
It is absolutely not reading my function!!
Which is best option to store confidential information in a page?Control,Session,QueryString etc ... ?And also the performance also should be good ... ?
View 11 RepliesI am working on a site in which some pages are to be run on secured server(ie https) & some on non-secured(ie http) eg Login, User Information, etc. will be run under https & View cart, etc. are to be run on http. Now, when user chooses some products in his cart, he is prompted to enter login details. After he fills in his login detail(ie in https), he is redirected to Checkout. But here the Session doesn't picks the value and it shows Session[UserID] value null. So, rather then redirecting to Checkout it shows MyAccount page. Does anyone know how to pass Session Value from https to http.
View 3 RepliesWe have a web site that implements a custom SiteMapProvider using a User Control added in the master page. I need to be able to limit the sitemap nodes added depending on the logged in user, that is, certain users should not see certain sitemap nodes. Currently, the login processing code determines if users are in the certain category or role and then sets a value in session state, for example, Session["UserInRoleXXX"] = "Yes"; I tried changing the code in the user control to check the session state, but I got the following error: NullReferenceException ... Object reference not set to an instance of an object." Can session state be accessed in a user control?

I have created a user control with a property named CurrentPage. When a link button is clicked it runs PostbackToPage() and passes a command argument in which then sets the CurrentPage property with this new value. On the page which uses the user control I am trying to display the updated CurrentPage property after a postback. When I click the link button to cause the postback the CurrentPage is the default value. However when I click it again it works as expected. So it seems to only work after 2 postbacks. How can I get this to work after the first postback?

1) I found that my viewstate was not being persisted across postbacks for web user controls. I ensured that the Enable Viewstate property was set to true (of the page)
2) The Viewstate isnt being persisted on the 1st postback.
3) However, it is being persisted from the 2nd postback onwards.
I stepped through the code to ensure that the Viewstate had the 2 keys that I was adding on page load. However, on the 1st postback, the viewstate is empty. Everything is ok from the 2nd postback onwards.

My app has broken after upgrading to ASP.NET 2.0. The problem is that Request.QueryString is empty when the SelectedIndexChanged event of a IE Web Controls tab strip is fired. It worked perfectly in ASP.NET 1. I have the tab strip contained within my own UserControl.

i have a usercontrol called navigationmenu whose data is static but varies with loged in1.empID 2.empType 3 Country my question is how can i cache the data of usercontrol based upon combination of these 3 parameters
View 9 Repliesi have 2 questions about output cache:1.is it just me , or does it seems that it is used only after the second time that the user reaches the webpage? if so, why, and how can i tweak it to my needs? my guess is that it wouldn't be logical to cache every time a user reach a webpage, but only when it happens enough times.2.i know that i can use "varybyparam" for using the output cache when the parameter doesn't change , but it seems that it would use the output cache even if there is no parameter , or if the specified paramter is not there. is there a way to overcome this?3.an old question that somehow marked as "answered" , yet i didn't solve : suppose i created a user control and i gave it values through the CTOR via the aspx file . is it possible to show the values from within the split/design mode? remember that i've talking about ASP.NET and not simply C# winforms . i write this because this question was on :[URL]and the answer that i got was for C# and winforms . i've tried to do the same for ASP.NET , but i've failed.

View 8 RepliesI have a number saved in session and am using it in a bunch of pages right now, and I was wondering if I could somehow access this session in my WebService.asmx file? It would be great since then that way I can fix my auto complete extender. I know I can use contextKey, but I am using that contextKey for something else. If session isn't possible in web service, then is it possible to use two contextkeys in auto complete extender, and how?

When i select, a department, it filters the list of the branch and shows only its branch when i open the branch pop up window.
