ASP.NET, HTML, JavaScript Snippet Support (VS 2010 and .NET 4.0 Series)

This post covers another useful improvement in VS 2010 - HTML/ASP.NET/JavaScript snippet support. Snippets allow you to be more productive within source view by allowing you to create chunks of code and markup that you can quickly apply and use in your application with a minimum of character typing.

Visual Studio has supported the concept of "snippets" for VB and C# in previous releases - but not for HTML, ASP.NET markup and JavaScript. With VS 2010 we now support snippets for these content types as well.

Re-positioning an HTML container with javascript onresize with a Master page.


I have an HTML <div> container that I float to the right of a gridview.  When the browser window is maximized, it looks fine.  When minimized, the gridview positions below the floating container and most of the data is pushed off the bottom of the browser - you have to scroll down to see it.

If I position the floating container above the gridview it looks fine in a minimized window, but looks real bad when maximized.

What I want to do is use a javascript: onresize event to re-position the floating container up or down depending on the window.inner.width AND do it with a Master/Content page structure AND do it for only the one page where needed.

I can capture the onresize event and display the window dimensions but haven't figured-out how to do it with a Content page that still uses the Master page.  I think I'm having a very "thick" week...

Rendering data with HTML tags in the DD Gridview for a selected column


I am having trouble finding out where and how to HTML Encode a cell's data on the Dynamic Data (v4.0) gridview of List.aspx.  As a simple case, suppose I have formatted cell data that is A<br/>B in the DB.    Obviously, I want A stacked on B in the cell.

It seems gridView1.HtmlEncode = true has gone away.

So maybe I'll try to catch it on the RowDataBound event:

protected void GridView1_RowDataBound(Object sender, GridViewRowEventArgs e)

            if (e.Row.RowType == DataControlRowType.DataRow)
                // Html Encode the cells


but this event never fires?

Has anyone figured out how to properly render HTML tags data in the List.aspx's GridView1? 

If I figure this out, then I can add a MetaAttribute called something like [EncodeAsHtml(true)] and be on my way.  Thanks!

Use .html method to output asp.net controls


Is it possible to use the .html method to output something like an asp:label ??  It doesn't seem to work for me unless they're standard html controls.  Here's my JQuery:

$(function() {
    $("#btnContinue").click(function() {
    $('#pre_register').html("<div id='post_register'></div>");
    $('#post_register').html("<asp:Label ID='lblUserName' runat='server' Text='Enter your desired user name:'></asp:Label>")
        .fadeIn(2000, function() {

Call a web method in Javascript


Hi All,

I am first time working on web service and Javascript and trying to call a Web Method (web service) on a button click in Javascript.

What I want to achieve is as followed: When the button is clicked, call the web method, get the return URL value and store it to a session variable, the redirect the page to another page. However, this works only when the internet traffic is fast, it give me error when internet is slow as the Javascript is executed much faster than the web service. Is there any way to handle this?  Would be much appreciated for your help! Cheers.

Query Sharepoint list, rich text columns returning HTML tags

Hi! So I have an issue that maybe someone of you have encountered as well. I am querying a Sharepoint list and creating a report from the data collected from this list. This all works fine except that one of the columns in this list is of the type "Multiple lines of text" and also supports "rich text" with different fonts, sizes and so on. This has the effect that the text returned from this column is wrapped in HTML tags that specifies how the text should be formatted. Naturally I do not want this HTML code to appear in my report so for now I have used custom code to do a string.replace and replaced for example <div></div> and <br> with "". However, this column also has url references to documents and these links shows up like this "/servername/site/subsite/Gemensamma%20dokument/Mwh.docx">http://servername/site/subsite/Gemensamma%20dokument/Mwh.docx There is some sort of double reference to the document that I guess like the HTML tags are embedded in the answer from the rich text column and this is not so easy to do a string replace on because the url varies with the different document and document names. My question really is if anyone of you have done a similar report that I am doing, and have encountered this fenomen with this sharepoint column and how you did to solve this? I have tried to creat

Javascript doesn't work on IE Mobile 6.12 ?

Hi, I wrote a simple asp.net page with few controls and a function in Javascript that make input validation. The javascript function is called on button click event. I use Windows Mobile 6 Classic emulator, and the javascript doesn't work at all.  I saw few posts on this forum saying that IE mobile works just with jscript and doesn't work with javascript. Is it correct ? Is that mean I have to change my javascript code to jscript code ? I always thought they are the same. Is there newer versions of ie mobile that works with javascript ? Thsnks, David

Asp.net MVC: How to call javascript function in Html.ActionLink

Calling a Web Service Method Asynchronously does not work in Console Application

I have a web service that has a CreateReport method that generates a report based on the specified criteria. When I call this method Synchronously using a Windows Application or Console Application, the call works fine and the report is created. When I call this method ASynchronously (CreateReportASync) using Windows Application the report is created. When I call this method ASynchronously (CreateReportASync) using Console Application the web service does not even get the call.  I am using VS2005 and .Net Framework 2.0.  So the proxy is automatically created with the Async methods.  I am not really interested the result of the method call, so I do not add a Callback Delegate.
