Visual Studio :: Boolean Variables Set On A Web Control At Design Time?
Dec 15, 2010
I'm trying to extend a RequiredFieldValidator in an incredibly basic manner.All I want to do is add a property that is a boolean that can be set at design time through the Properties window of Visual Studio 2008.I can get the control to build and render at design time but as soon as I set the Boolean property the control breaks.There is no trouble at run-time with this control, only design time.Below is the code,the placement in VS and the error message:
1) The Code:
[Code]....
3) This is what the design surface shows after that change is made:
In case the image is missing or broken and to help the search engines, this is what it says:
"An unhandled exception has occurred. 'False' could not be set on property 'ShowValidatorSummaryLink'"
I'm sure I'm missing something or there is a serious bug here.I can't imagine that setting a simple property on the design surface would cause so much trouble.

can't connect to sql 2005 express sp1 and vs is also sp1. 2) Which my guess is because of the database connection not being able... design view is not able to pull in the application for design, it's as if there is no theme and css just white background and black print.

suppose i've created my own user control, and it has a textbox and a property for the textbox so that if i use the user control from within the aspx file, i can give the property a value. for example:
[Code]....
is it possible to also set the property to be seen via the desing mode , just as it works for other (built in) controls? maybe a different method to implement the same scenario?
if you still didn't understand what i mean : after setting the value of DefaultNum1 via the code i've written here, i expect the textbox associated with this property to be updated as well to '1' via the design mode (and split mode). of course it won't work using the current method, since VS cannot guess what is going on with the property and understand that all of its purpose is to assign an initialization value for the textbox.

After I imported a VS 2008 web project to VS 2010, I can't view aspx pages that have master pages in design mode. The page design mode displays "error creating control - contentplacehoder1 object reference not set to an instance of an object." The project builds and runs fine though. I have only one master page that all other aspx pages reference and I don't have any nested master pages.

I have a simple HttpHandler that generates a dynamic image based on query string parameters and a custom web control that renders an image tag pointing to the handler as its 'src' attribute. All works fine when run in the web server, but at design timethe control displays as the "missing image" icon (red x in a box). The handler is registered in the web.config with a ".ashx" extension. The RenderContents method in the control looks like this:
output.AddAttribute("src", ResolveUrl(string.Format("~/Sparklines.SparkHandler.ashx?stype=pm&w={0}&h={1}&sv={2}&ev={3}&cv={4}&sc={5}&ec={6}&mc={7}&gs={8}",
Width.IsEmpty ? 100 : Width.Value,
Height.IsEmpty ? 15 : Height.Value,
caleStart, ScaleEnd, CurrentValue,
ColorUtils.ColorString(StartColor, true),
[code]...

I have multiple solution configurations defined (Debug, Release, Local, Test, Production etc). I would like to assign this Config into a c# variable.Something like:
string configName = #(Config);
Is there something like this? It has to come from the solution configuration. I know I could hard code the solution configurations into the c# configName variable using multiple if conditions but wondered if there is something like above.

I want to see the design view while I am designing a site in ASP.NET using visual studio 2010 Ultimate, but I wondered there is no such option as design as there were in VS 2005 or VS 2008.
[URL] normally in the attached red portion below supposed to contain a option to switch to design view. But there is nothing ..

how to do this.or is there any template that one can use for the following-
using visual studio to design questions and answers with outcome of the grade immediately after submition and with timing.
For example, having questions 1 to 10, providing options like A, B, C,D, then let students choose from the right answer from the questions, then, after submition, an outcome of grade is displayed based on the right answer.

My VS 2008 Design button is broken, i.e. I click on it an nothing happens. I've rebooted, restarted, reinstalled VS, installed VS 2008 sp1 - nothing fixes this! Getting ready to try dynamite.
Then when I close VS it crashes, i.e. i get the message "visual studio is not responding and needs to restart".

Usually using Visual Studio's debugger is a breeze. Scanning through Locals quickly shows the values of variables, etc. However, I'm at a loss how to find out the values contained in session state variables? Can anyone give me a hand?Lets say I put a breakpoint right after:
Session("first_name") = "Rob Roy"
How do I view the value contained in Session("first_name") from locals?

As far I know this is not supported for asp.net projects. It's quite handy for testing static/shared functions.any info if this will be available in future versions? Or if there are any alternative ways to test your functions in design mode?

This error only happens when I launch an existing application, if I create a new app the error does not appear on that site. However if I try to enter Design mode the Windows Installer opens and hangs. I can still edit the code and even launch the app.
If I click "OK", I get a dialog box that starts a Windows Installer that does not install anything, it justs sits there. If I "cancel" the installer, VWDE dies.
The only thing different on my laptop is that I had Office 2007 Trial installed along side Office 2003 before I installed VWD, I then uninstalled the trial and used the clean-up tool at [URL] to clean up the trial.
I have tried to repair VWDE, I have uninstalled and reinstalled VWDE with no change. Ialso have VB Express running and get no errors when launching it.

When I'm in Design View I can't scroll down to the bottom of some of my pages. I've scrolled down as far as I can and the bottom is cut off. This doesn't happen on all the pages. I tried increasing the height for the ContentPlaceHolder.

i'm quite a newb in asp.net , so here we go:i used the dreamspark project in order to get VS 2008 pro (free and legal) , and then i started experiencing with asp.net .the problem is that whenever i choose the split mode, it doesn't go there at all, and whenever i choose the 'design' mode, the tab itself is frozen yet it's possible to close it. it doesn't matter what the file (with the aspx extention) has in it (even a
new blank website) , it always happen.i've tried to re-install VS2008 (after uninstallation&restart) and i also tried to uninstall anything related to dot net (and then install what is needed again through the installer of VS2008) . i even tried out the express version but it didn't work for me.
