Design view displays blank page

Posted By:      Posted Date: September 05, 2010    Points: 0   Category :ASP.Net
I'm relatively new to VWD and am using the Express version.  My web site is simple with a few connections to SQL Server data and to XML documents just to populate controls to display data.  After adding a new web page, linking its controls to an XML document and running it successfully, I discovered that I can no longer display the page in the Design view, I just get a blank screen.  To further confuse things I opened my root master page, which appears just fine.  I then opened the master page derived from this root master and it shows me content placeholders but not the controls inside the content placeholders.  If I have one of the master pages open in VWD and then I open the base page, I now see the data from the root master page but nothing from the base page or the derived master page. I think I'm doing something basically wrong but I don't see it.  Before I start deconstructing my web site I'm hoping someone can help me.  I have looked at a lot of posts on this site but I don't see one that answers my problem.  I did see the one about style and links and their ordering in the aspx file, but this isn't my problem as I currently have neither of these in use. TIA Jon

WebDev.WebServer.exe has encounted a problem and needs to close when trying to view page in browser


Hi, whenever I load an aspx page in vwde2008, I get the message in the subject of this post.  After I click Ok on that, I get a dialog box, Unable to Connect to the ASP.Net development center.  What can I do to troubleshoot?

I am using Windows XP SP3, vwde2008 with SP1, on a HP desktop.  Also using Office 2003 if that is relevant at all.

Thanks, Justin

Custom Control Design view error



I have created a custom control from scratch and it works fine as in you can build the project that uses it and it works fine at runtime. Problem is when you go to design view the control shows an error in the place of where the control should be rendered.

Error: '<SomeValue>' Could not be set to '<SomeProperty>'

This shows up on all my custom set properties. These properties are created as basic as possible. I can give the properties values in Source view and run the app just fine. I can even add a Onclick event. If I don't set any custom properties the control will render fine in Design view. It's only when I set a value to a custom property.

Property Code Example:

public string Text
                string ret = "";
                object obj = ViewState["Text"];
                if (obj != null)
                    ret = obj.ToString();
                return ret;
                ViewState["Text"] = value;

I've even removed the Category and Description tags with no difference.

I don't know if what I said makes sens, but I hope it

creating different sub page design template in sharepoint website


I know very little about sharepoint and have outsourced the design of a master page and sub page design for a new website using sharepoint. i received a site master file with all of the necessary images and the home page works just fine. However the file i received for the sub page design template was an ASPX file with the following instructions:


Here I enclosed the inner page layout file. You upload this file by using following instructions. you can change & edit the blue menu section in the master page itself. If I change into modifiable section you need to add the menu in each and every page, otherwise it will show as empty block. Please let me know your comments.


Steps for uploading inner page layout page.

Visual Studio 2010 Shows Blank Page during web development


I just upgraded a web project from VS2008 to VS2010 Ultimate (Windows7 64bit, IE8/Google Chrome. When I run the web project in the development server (by hitting F5) everything acts like it is supposed to except everything comes up blank. Even the directory structure page is blank, just an empty HTML open and close shell. I get no errors no indications of failure, nothing. When I try to use google chrome I get the same blank page no matter where I navigate to, even if I try to navigate to a non-existant location on the dev server. I know the code compiles and acts correctly because I can deploy it to our QA servers without issue. Any ideas? 

Add page numbers for paging in data view web part


Hello all,

Has anyone found a solution that will allow me to have page numbers for paging in a data view web part. For instance, if I have 40 items/rows and I set the paging to display 10 items, I'd like the paging to show 1 2 3 4 rather than showing 1-10 and having to click next over and over to get to a specific item.

I found this article, but it is for 2003 and doesn't seem to apply to 2007 or if it does I am not able to really figure out how.


Please help!

Thanks in advance.
