I have a web page where I only want controls to appear under certiain conditions. I know I can set the visible property to false but it still takes up space on my page, and I would like to take it out completely. Is there a setting to do this? I have tried Controls.Remove(Button1); but this code doesn't seem to work.

Our IIS server (v7) has the following settings in [Custom HTTP Headers] for our whole site:
Pragma: no-cache Cache-Control: private, no-cache, no-store, max-age=0, must-revalidate, post-check=0, pre-check=0 X-Powered-By: ASP.NET
Out of the whole site, there are some pages that require the "no cache" setting to be removed for them to work properly. This was done manually by our IIS Administrator until recently. Now we were told that we need to do it programmatically on our end. The following were the code snippets (VB.NET) we have used with no luck in success.
Method-1
Response.Headers.Remove("Pragma")
Response.Headers.Remove("Cache-Control")
Response.Headers.Add("Cache-Control", "private")
Response.CacheControl = System.Web.HttpCacheability.public
Method-2
Response.ClearHeaders()
Response.Headers.Clear()
Response.CacheControl = "Public"
Response.Cache.SetCacheability(HttpCacheability.Public)
Response.Cache.SetAllowResponseInBrowserHistory(True)

I am programatically adding a control to an aspx page and binding a server side event to an index changed event inside the control. (It's a RadListBox from Telerik's ASP.NET controls) The problem is that on the postback triggered from the control, the event doesn't hit its eventhandler because on the postback the control isn't defined. Is there a way to handle this without having to retrace the logic taken before and rebuild the controls so the events that stem from it are processed?

View 4 RepliesI am trying to add a user control into a div at runtime. I can add the control no probelem but it overwrites the previous control added.Basically, I am trying to add passengers to a travel system - the passenger details are in the user control and I don't know in advance how many there will be. I have an add new passenger button which should append the new user control into the div without overwriting the previous passenger. The code is c#/.net 4. I have tried to save the control data into viewstate and re add it with the new one but that also doesn't work. Here is a snippet of the code I'm using
foreach (Control uc in p_passengers.Controls) {
Passenger p = uc as Passenger;
if (p != null) {
p.SaveValues();
}
}
however, p.SaveAs() (just writes the control values into ViewState) is never hit.
I am using Eval inside a datalist to populate a hyperlink within the datalist with a navigateURL value and I am using it as follows:
<asp:HyperLink ID="HyperLink_FullStory" runat="server" Text="Full Story" NavigateUrl='<%#Eval("LinkAddress")%>'></asp:HyperLink>
The issue I am facing is that the current page URL is getting appended to the 'LinkAddress'(the URL being fetched from the database) and thus,the final URL formed is not a valid one.Can someone suggest how do I remove the current page URL? Is there any way it can be done without writing code in the code behind page?
I need a way to change the ActiveViewIndex of a multiview control based on some query results. Right now I test to see if I have rows returned from my linq query. If so, set a certain view active. If no rows are returned, I would like to set a different view active. I would like to do this on Page_Load if possible.
Right now I get the fatal "Object reference not set to an instance of an object" error on page load with it bombing at line 12. My count is given a value at runtime so that is not the issue. Can anybody tell me why this is and how to get around it. Code is attached.
I also tried this both the pre render and Page_Init event but both yielded the same behavior with the Object reference not set to an instance of an object error. I can do this just fine in an onclick event for a button, but now I need a way to run a test and set the default view when the page loads. Seecode below
protected
void Page_Load(object sender,
EventArgs e)
{
eCrystalPSGDBDataContext psgDB =
new
eCrystalPSGDBDataContext();
int count = (from st
in psgDB.studyTbls
where st.patientid_i ==
Convert.ToInt32(Request.QueryString["PatientId"]) && st.studystatusid_i
== 1 select st).Count();if (count == 0)else
if (count == 0)
{
StudyInfoMultiView.ActiveViewIndex = 1;
}
else
{
StudyInfoMultiView.ActiveViewIndex = 2;
}
}

View 4 RepliesApparently I am not familiar with the Life Cycle of a page in ASP.NET. This became apparent when I wanted to dispose of a Session variable after I left the page. I did what made the most sense:What I didn't know is that this would be called when I go from AND to the page. What I am wanting to do is dispose of that Session variable whenever the user leaves the page.

View 1 RepliesI've got the following Setup in my Theme:
App_ThemesDefaultStyleSheet.css
App_ThemesDefaultPrintStyleSheet.css
The PrintStyleSheet.css file has a set of printing css rules set in them wrapped in an @Media Print { } block.
I need a way to programmatically remove the PrintStyleSheet.css from the list of css files for ASP.NET to inject based on some flags. (Some instances we want to print the site verbatim without custom formatting).
I know i could build a seperate theme without the PrintStyleSheet.css in it and switch the theme programmatically, however this would introduce duplication of my master stylesheet which is not acceptable.

View 1 RepliesVWD 2008 Express. Visual Basic.
I want to do two things:
1. Place a button on my aspx page that when clicked causes the page to be printed.
2. Put code behind that makes a page print.
In my global.asax file for my ASP.net project, I am checking for certain conditions. When those conditions are met, I want to automatically execute javascript code when the page runs.
This is my code:
if condition Then
Response.Write(" < script type=""text/javascript"" > ")
Response.Write(" // Javascript code to do stuff ")
Response.Write(" < /script > ")
End If
While this appears to work to execute the Javascript code, I don't think it's a best practice because this code will preceed all of the HTML of the page that gets loaded.
What is the best way of programmatically tacking on some extra Javascript code to be run when my page loads?
