Rendering ASP.NET Script References into the Html Header

Posted By: Amit Mehra     Posted Date: March 23, 2010    Points: 2   Category :ASP.Net
One thing that I've come to appreciate in control development in ASP.NET that use JavaScript is the ability to have more control over script and script include placement than ASP.NET provides natively. Specifically in ASP.NET you can use either the ClientScriptManager or ScriptManager to embed scripts and script references into pages via code.

*.axd script references not being rendered to browser


I'm running VS2010 with .net 4.0, and am running into issues with the .net ajax script tags mysteriously not being rendered to the browser.

So far I've reduced it to a scenario where I set the DataSourceID property of a databound control.  More specifically, I've only tested it on a Gridview and a DropDownList.

This can be reproduced fairly easily on my machine by following these steps:

1. Create a new empty Web Application Project

2. Create a new Web Form

3. Add a ScriptManager inside the form

4. Add a DropDownList and a DataSource (I used an ObjectDataSource)

5. Set the DataSourceID property of the DropDownList to the ID of the DataSource.  This can be done either declaratively on the .aspx page, or in the code behind in the aspx.cs page, and both produce the same results.

6. Open the page in a browser and watch as you get a javascript error stating "Sys is not defined" and notice that the page source contains no script tags referencing *.axd scripts.

Here's my source code showing my set up:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="ScriptResourceFAIL.Default" %>


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!

Page Header, PrintOnFirstPage=False, HTML render fine, PDF export leaves extra space

As it says in the header.Setup:SSRS 2008, VS 2008 SP1Local Mode, rdlc fileDesign:Make a 1/2" Page header with a text box in it. Set PrintOnFirstPage=FalseBody contains a Table that spans multiple "hard" pages.Results:Renders to HTML in the report viewer just fine.PDF export leaves blank 1/2" at the top of page 1. With no header for page 1, I had hoped it would remove the extra space the same as in the report viewer.Question:Any way to tell SSRS not to leave space when page header is turned off for the first page?Attempts:Tried putting everything in a rectange in the header and set the visibility to false. Still leaves space.

Show Tag Properties in SPD 2007 is rendering page in html


In Designer 2007 I am trying to see the properties of my ListFormWebPart. When I try to see the tag properties, the tag properties popup comes up, but instead of showing my all the properties configurations, the .aspx page renders in the popup!

I am really hating SharePoint and Designer.  It's the buggiest thing I've ever seen.

There are no mistakes; every result tells you something of value about what your are trying to accomplish.

Script Component Doesn't Retain References To DLL

I'm using SQL 2008 Integration Services and I made a reference to an external Dll. I save the changes but when I go back into the script component, the references are gone!!! What happened? How can I make my reference in the VB.Net script portion of the Script Component (not Script Task) stay/persist/stick around?

Publishing HTML and RichTextField display HTML code - not rendering


Hi there, 

I have several custom columns of type "Publishing HTML", and a page layout several controls which point to the columns. :

<SharePointWebControls:RichTextField DisableInputFieldLabel="True"  FieldName="WheelImage" runat="server"></SharePointWebControls:RichTextField>


The problem is that in the end result, the page shows escaped HTML (eg. <p></p>) rather than the rendered output I would expect. 


Oddly - when it edit mode - they render fine, showing the rendered output. But in the 'reader' view, it shows the raw HTML. 


I have also checked the 'edit html source' in edit mode - and it looks fine, like HTML. But the browser source of the output page shows escaped html: &lt;br/&gt;


I found this describing the same problem, but its not a solution - as this happens on any browser:




Anyone any ideas?






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.

Client script not running


Dear all,

in my MVC 2 application, and in the shared Master Page I wrote this little script for menu handling :

<script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"></script>
<script type="text/javascript"> $(document).ready(function () {   
     $('#nav li').hover(  
         function () {  
             //show its submenu  
             $('ul', this).slideDown(100);  
        function () {  
           //hide its submenu  
            $('ul', this).slideUp(100);           

The script, that shows menu items when the

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...
