how to put what i am looking for. The best i can describe it is a flowchart type of layout that shows your all your ASP.NET pages and how they are linked to one another.
I have a web application develped using VS2008 and the Dundas Charts add-on. I understand that Dundas Charts is no longer supported by Dundas and now belongs to Microsoft. I found what appear to be the chart controls and VS integration downloads:Microsoft Chart Control for Microsoft .NET Framework 3.5Microsoft Chart Controls Add-on for Microsoft Visual Studio 2008What I do not know is what happens if I install these downloads. Does my original Dundas software cease to work? Does the new MS Chart software work like the Dundas version did and is fully compatible with my existing charts? Do I need to rebuild my web sites using the MS Chart integrated software? Does the old Dundas dll file in the in folder have to be replaced or will it work as is? I have not found anything that describes how to install and use this software and the functional differences from Dundas to Microsoft ownership.
I wonder if it is possible using the Chart 3.5 in Visual Studio 2010, I have pages that use this control, but do not want to migrate the project to the NET 4.0
I like the way that the chart control seems to automatically determine the X axis range for me based on the data, but in this case, the data can only be whole numbers.
What is the easiest way to specify whole numbers for this axis?
I chose the option to create a new ASP.NET Web Application (C#) project using VWD 2010 EXPRESS. Normally I choose the create an empty web site option. Anyways, It seems that everytime I needed to make a change in code behind that I would have to click save, then debug>build for the changes to take effect. This was working fine for three days, now all of a sudden it has stopped working. It doesnt seem to rebuild when I click build...though the output message says it succeeded.
I have even removed entire codeblocks from the codbehind (one that populated a dropdown), yet the drop down is still populated when the page is previewed (I have cleared the browser cache as well!). Also, I have tried to set Label1.text to various values and that does show either, like its not in the code.Is there a bug in VWD, or is there a setting I could have clicked unknowingly? I am gettingsome strange errors as well. For example, I am getting object reference not set to an instance of an object errors and the line it points to is a totally empty line
i have created a web project and i want to test it.when i click on debug or click on default page to view on browser , ASP.NET Web Development Server Works but nothing appear in my web browser . even i used internal browser ofVisual Studio 2008 but it shows this message :
I'm using a 64bit dll (system.data.sqlite) in an Asp.net MVC app in VS 2010. The application runs and debugs fine, but all the aspx and ascx pages show errors when editing in Visual Studio 2010 and intellisense doesn't work. This is a VS2010 regression bug. Does anyone have a work around? (OR)Does anyone know of a free, reliable, production ready embeddable database that doesn't cause a 32/64 bit problem?More DetailsApparently this worked in Visual Studio 2008 and this has been is a known regression bug in Visual Studio 2010 for several months. I don't want to revert to VS 2008 and I don't want to debug in 32 bit mode.
I have web application that needs to debug and deploy as a 64 bit mode because it uses uses some unmanaged 64 bit dll's like system.data.sqlite. Also, I prefer debugging in 64 bit mode because it allows us to test some high memory use cases. After a lot of fiddling, Asp.net will deploy and run just fine. However all the aspx and ascx pages show errors and intellisense doesn't work when editing them in Visual Studio 2010. Apparently this worked in Visual Studio 2008 and this has been is a known problem in Visual Studio 2010 for months. I don't want to revert to VS 2008. There was a work around posted on SO here but it didn't work in my tests, limits debugging to 32bit mode, and also feels a bit hacky (I think it only works for VS Express style websites). Has anyone made this work in a web application or have a better work around?For those who are interested Visual Studio 2010 has two other problems with 64bit dlls that I have managed to work around.
Problem 1 - Cassini: Cassini can only debug in 32 bit modeSolution 1 - CassiniDev or Localhost: Debug using localhost or compile CassiniDev (an opensoure variant of cassini) in 64bit mode. I like the zero config simplicity of debugging a new web app with cassini so I used CassiniDev. You just stick the dlls in C:Program Files (x86)Common Filesmicrosoft sharedDevServer10.0 and it works (I recommended making a backup of the Cassini version you will be over writing).Problem 2 - MSTest: By default unit tests run with MSTest fail to load 64bit dlls.Solution 2 - AnyCPU & 64bit host process Instructions here, set local.testsettings to AnyCPU & 64bit host processI'm starting to think the whole setup is too little hacky and I'm on the verge of giving up and restructuring my application to not use a 64bit dll. I'm also really disappointed that Visual Studio 2010 caused all these problems. Can somebody make MS fix the regression bug they created?
I am taking over for a website in ASP.Net (VB.Net) where the live site is compiled code. So there's no code behind pages. So other than the ASP.Net pages, it's just DLL files in the bin folder.It's also at an ISP where I have no control over the server to remote in.
I have gotten from the client, what I believe to be the latest and greatest code. So there's code behind pages and also a vbproj file. It seems to be have done in an early version of Visual Studio.Thinking maybe 2003.I only have Microsoft Visual Web Developer 2010 (I've been using) and VS2005.So I made a very basic change just to test the waters and built the website, which made a brand new DLL for the site in bin. Also new pdb and xml document. It works fine on dev.I uploaded just this DLL to live. However on live, when I get to the part where I'm submitting a form.I get a very non descript error.

I can't see the line number of the error + am I compiling the DLL wrong?I trying to figure out how to do this without breaking the live site. Is there a way to tell what version of .Net it's compiled in.
I'm used to working with VS 2008 and toggling bookmarks in aspx pages was very useful, however in VS 2010 I'm unable to toggle bookmarks using the CTRL + K + K or the actual "Toggle bookmark" button from the bookmarks tool. Is there an option to enable this on the ASPX page, it works everywhere else though.
may be i m asking a very vague question, but how to remove the dots that appear for spaces in the design and code view of the page. Dont know how it came and how to remove it and it looks very confusing.
I inherited a web site which contains many stand-alone aspx pages (with the .NET code in the page rather than in a code-behind file). I'm wondering how to debug these pages; I cannot set breakpoints in them (I can set breakpoints in the code files on the site without issue). I'm using Visual Studio 2008.
I am not sure this is the right place to ask.I am using Visual Web Developer 2010 Express, and have loaded an existing project.I have an image folder, and in the folder I have some images (.png)I need to find all of the ASP.NET pages which uses one of this image,but had no luck. There are hundreds of ASPX, ASPX.vb pages to search...IS THERE A WAY TO SEARCH WHICH ASPX or ASPX.VB pages are using a image file?For example,If I have C:TESTIMAGESTEST.PNG file,I want every file in the project pages which includes:
I have one .xamel page and this one is default page (first page) and then I added a new one page (named page2.xaml) in same solution. I added a button on the firs page and i want to navigate to a second page when i click on button
Using the vertical split view, it appears as though it defautls to displaying the source on the left, and the design view on the right. How can I switch tme around?
i have encountered a problem on how to load the database images to be display in the Image content in the web pages. I am currently using an Access database with a table "Images" and there are 4 columns in it. "ImageID", "ImageDescription","ImageofPicture","Description". Below is my code: Words highlighted in bold is where the problem occurs. No image is display in the Image box but theres a red cross at the top left. Image description is displaying fine in the textboxes

I just upgraded to 2010 and converted my VS 2008 ASP.NET web application. There were no conversion errors and everything displays in the Design mode correctly but when I try to View in Browser or debug the site won't display. I just get a blank page untitled page displayed.
I am wondering if it's possible to work on Content Place Holder window without seeing master page template?
The second problem i've noticed is that when i try to add a table (1 row, 3 columns) to my content place holder and then try to adjust the width of those columns the whole layout of my page is getting messed up to the point that i have to use ctrl+x to go back to previous stage. The master page was very complicated but i finally got it to work and i don't understand why while i manipulate contentplaceholder the layout of the master page is being affected. (only when adjusting tables)I am new to Visual Studio and was wondering of any known standars in that matter.
I have a grid view with first name, last name and email address and View details button
if I click on view details button and display all the details
I want to update Email address, first name in that page.
after updating, I want to return to previous page where datagrid is there.
I want updated data in that datagrid.
I did this by creating different page and after clicking on return button, instead of going to previous page, I m redirecting to new page with the datagrid.
If I click on view details button on that page..its throws runtime error.
After searching, I got EnableEventValidation=false, it is working fine, but viewdetails button is not working.
