I have migrated .NET 1.1 code to .NET 3.5. Getting the following error in the page in design part: "Error Rendering Control- An unhandled exception has occured. A relative URI cannot be created because the 'urIstring' parameter represents an absolute URI. " It is happening for control:
<asp:hyperlink
id="hypPrint"
NavigateUrl="javascript:window.print();"
EnableViewState="False"
runat="server">Print Current Page</asp:hyperlink>
"NavigateUrl" propery is causing this error to occure.
I removed thisand tried, this error goes. But I need NavigateURL for my functionality to work.

I just updated my site to run off .Net 4 (mainly for SEO) and love it so far but now just got my first problem. I am updating the controls for my forms authentication, while I have updated the Login control and used the RenderOuterTable=False with no problem I am now updating the CreateUserWizard and it does not have a RenderOuterTable.
This is causing the page to look like butt because of the table, so the question is now how do I stop it from rendering the tables? When I search on google I find posts sites saying to use RenderOuterTable and others saying your SOL.
I can not see microsoft really leaving us SOL on this expectialy since tables are not supposed to be used for site layout and the hole point of RenderOuterTable was to let users avoid tables.
I have created user web control library project and these controls i'm using in my web application. These User controls just works fine in my local machine but when i moved this project(including Library) to our Local server , it is throwing security exception

Anybody knows why this error occuring...?
Is there any way to prevent the asp:Login control from rendering a table around my controls? Rendered HTML: <div id="credentials">

When trying to render the control, I get the following exception: Security Exception Description: The application attempted to perform an operation not allowed by the security policy.

The solution to this, as provided by a quick Googling, is to use caspol.exe to add full trust to the recaptcha.dll assembly. C:\%path%caspol -af C:inetpubwwwroot\%path%in ecaptcha.dll At this point, I get the following error: ERROR: This assembly is not strong name signed Short of downloading the source code and recompiling it locally, is there any other way to get this working?
I'm writing an HTTP handler in ASP.NET 4.0 and IIS7 and I need to generate a file-not-found condition.
I copied the following code from Mathew McDonald's new book, Pro ASP.Net 4 in C# 2010. (The response variable is an instance of the current HttpResponse.)
response.Status = "File not found";
response.StatusCode = 404;
However, I found that the first line generates the run-time error HTTP status string is not valid.
If, instead of the lines above, I use the following:
response.Status = "404 Not found";
Then everything seems to work fine. In fact, I even see that response.StatusCode is set to 404 automatically.
My problem is that I don't want this to fail on the production server. So I'd feel much better if I could understand the "correct" way to accomplish this. Why did the first approach work for Mathew McDonald but not for me? And is the second approach always going to be reliable?

Two separate questions, but sufficiently intertwined that I'm going to try the two together....
Firstly - User Controls and Behaviours
I have a User Control which contains a few visual controls. I am attaching some behaviours by using GetScriptDescriptors and am passing some JavaScript to the browser using GetScriptReferences. That is all rock solid and working well. However, when developing, I did discover that I couldn't attach the ehaviours to the User Control itself - not surprising as rendering a User Control does not create a DOM element which represents the actual control. So, I have attached my behaviours to a "random" TextBox within the User Control.
So - first question, is there a better way to do that? For example, should I always be rendering a SPAN as an element to surround the control? Not sure what that would do to the robustness of the rendering. What is the right way to attach a behaviour to a User Control.
Secondly - Accessing those same Behaviours later
Assume I have placed a User Control on the page. That User Control exposes a Property (actually a Javascript Function of course) which does "something" to the control - for the sake of example we'll say that the function is set_Border(colour). I then have a behaviour on the same page (actually an Extender on a different control) which needs to call the function. I have a reference to the User Control in my script, so I have tried TheControlReference.set_Border('red') and find that my control doesn't support the set_Border method.
I guess this is probably because the behaviours are not attached to the User Control itself, but to a GUI element within it. Hence, I suspect that the answer to the second question lies within the answer to the first.
I have a custom control that renders different controls based on a property value. This all works correctly until i try and add a rating control to the control. When i render both controls in the CreateChildControls the control is rendered properly.
However when i try to add layout by overriding the RenderContents method and rendering controls there, an error is generated
Extender controls may not be registered after PreRender.The code shows both methods of creating the controls.

I am trying to implement the Ajax HtmlEditor into my application. I currently am using a regular TextBox to load and save some data to some EMail template files and had to do some work-arounds to get it to accept the HTML Input. I am trying to upgrade it to use the Editor, but as soon as I insert the Editor and do a PostBack, I receive the Security Exception below. There is absolutely no change to the code-behind, so I don't understand the issue. There is so little on Google for the Version 3.5 Editor that I'm stumped. I have Debugging enabled, but it won't give me the Soruce Error either.

I have a control used in our CMS and we don't have the source code for it, what I would like to do is change the rendered output of this control.
Now, I could have a check in my base Page class that checks if the control is being used on the page and then change the html that needs to be altered, but that seems a bit excessive for just 1 usage.
So is there any other way of changing the behaviour of the control without the source code? I'm thinking not other than the way described above.
I am just playing with custom controls, and have one built that looks like so:

I'm pretty sure its the Rendering / CreateChildren process that I'm not doing right. Problem is I cant find a good example that shows how to rerender your usercontrol when something needs updating.
I am outputting the entire HTML for my server control as follows:
public override void Render(HtmlTextWriter output)
{
output.Write(myStringBuilder.ToString());
}
myStringBuilder is a StringBuilder object that is manually built in a separate private method.Is this an efficient way to do it? Or is it better to pass the HtmlTextWriter to my private method and make multiple calls to HtmlTextWriter.Write()?
I am testing my website in numerous browers and have discovered (amazingly) that the asp:menu
control does not render properly in both the above browsers! Given that these browsers must account for
a large part of internet traffic it is curious that microsoft have not fixed this. I have looked at CSS Friendly but
if looks like a lot of work and change for my websites just for the one control that does not work.
I am developing website using xmlhttp request.I am using treeview control in a webpage.I am sending xmlhttp request to page for adding a treenode to treeview control.I added a node in the treeview control and i render the treeview control html using control.render method and send html to client through without postback.But i am not able to maintain the state of treeview control like selected node and expanded nodes.So I want to send state info to server through xmlhttp and how to update the state info in server,aslo i need to update the treeview control javascript objects like treeview_data which maintains the treeview state when i return back from server.
View 1 RepliesI render some markup dynamically in a Web User Control, can I get that out in design mode, and not only runtime?
public override void RenderControl(HtmlTextWriter writer)
{
if (this.DesignMode)
writer.Write("<p>In design mode</p>");
else
base.RenderControl(writer);
}
... nothing happens when I check the design view of the control. Not if I remove the if (this.DesignMode)-condition either.
I can successfully add graphs to any pages in my MVC solution except any pages within the Project Folder - I have no idea why as the same code works in every other folder - the image of the graph in the Project folder renders just a red cross - can anyone think of anything it could be? - I had a colleague check I wasnt going daft and the code looks the same and the page only has a graph.
I ripped out all the code so that the index page only has a graph within the Project folder and yet it still doesnt render correctly.
why the following code bombs with a NullReference exception.

I just want to output the html for the menu control to a string, if I remove the line that adds the new menu item or I change the control to a calander control instead of a menu control the it works fine.
I have placed a ratngs control like the one shown in the tutorial. When I debug the page, I cannot see the ratings control. However I can hover over where the control is, and it will show the ratings tooltip (e.g. 1, 2, 3, 4 and 5), but no stars.
View 2 RepliesI have a ReportViewer (ver 10) that is rendering far wider than the box it's meant to display in. The problem is that the Parameters area is appearing much wider than the actual report area. If I put an "overflow: auto" in the div that contains the ReportViewer control, then I get a horizontal scrollbar at the bottom, but then in order to click the "View Report" button I have to scroll way over, thus moving the entire report.
Ideally I would like the Parameters area to stay stationary, but a horizontal scrollbar to appear on the report area so that it can be scrolled if necessary. What is the best way to go about doing this?
Here's what my control setup looks like now:
<div class="reportingFrame" style="text-align: center; width: 100%; overflow: auto">
<sam:ReportViewer ID="UiReportViewer" runat="server"
AsyncRendering="False"
ProcessingMode="Remote"
ShowExportControls="False"
ShowPrintButton="False"
ShowPromptAreaButton="False"
ShowRefreshButton="False"
SizeToReportContent="True"
Width="100%" />
</div>
Currently I'm looking at some jQuery tricks to reformat the output from the ReportViewer control into a better system
