GridView crashes when user enters html open "<" or close ">" characters in a textbox

My GridView is bound to a sql data source and allows editing of fields. Coding is in C# and JavaScript. Using Visual Studio 2008 in test mode, if I enter a less-than "<" or greater-than ">" character in a GridView textbox an error is immediately thrown upon pressing enter: "Microsoft Visual StudioMirosoft JScript runtime error:Sys.WebForms.PageRequestManagerServerErrorException: An unknown erroroccurred while processing the request on the server. The status dode returnedfrom the server was: 500"When the < or > is entered in production, the page aborts and loads the application start page. I need to be able to catch and replace those characters BEFORE the error is thrown. I've tried hooking OnTextChange code to the textboxes, but the error is thrown as soon as I press enter...the OnTextChange code never runs. Any help will be greatly appreciated.

It is possible Html Formatted Textbox in RDLC (microsoft Report Viewer)

I am trying to create a rdlc report.   One of the fields in the report contains HTML formatted information. e.g. (It's a text field which is populated from a Rich Text Editor similar to one we have here).   When I put the content of this, in a text box of RDLC file, it shows HTML instead of formatted output.   I have been doing this in Crystal Reports using Text Format tag in there.   Is there some similar option available for RDLC text box too? I could not find any.

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.

Textbox Editable GridView in ASP.NET

This article describes how I made a fully editable gridview in C# using ASP.NET 2. The idea is that the GridView looks and works like an Excel spreadsheet. You see all the cells in the table, and you can edit any of the cells you like, and they are automatically updated (i.e. saved to the database). This is very often how people expect data tables to work in web pages, and I've often seen people clicking in vain on un-editable gridview cells, somehow expecting to edit them, and not understanding that they need to click an Edit button at the end of the row.

Custom Editing Behavior for DataGridView TextBox Columns

For various reasons I'm using a DataGridView instead of a ListView, and while configuring the DataGridView to look like a ListView wasn't much of a problem, there's one thing that got on my nerves, which is the behavior of textbox cells in edit mode: It is much too easy to leave the edit mode accidentally, simply by pressing the cursor keys at the wrong time. For example when the text caret is positioned behind the last character of the textbox cell content, and you press the right arrow key

Rendering ASP.NET Script References into the Html Header

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.
