Building a grouping Grid with GridView and ASP.NET AJAX toolkit CollapsiblePanel

Posted By: Rahul     Posted Date: November 13, 2009    Points: 2   Category :ASP.Net
 
I've posted an update to this post to apply on demand loading of Details data using ASP.NET AJAX PageMethods. I'm demonstrating the usage if CollapsiblePanelExtender client events on the new post. Check it out.

I admit, Matt Berseth is really inspiring me! Few days ago I pass through 2 of his great posts:

.Surrounding your Data Table and Dialog Controls with ComponentArt Styled Panels
.Building a Grouping Grid with the ASP.NET 3.5 LinqDataSource and ListView Controls
The first one is pure design tips one which I used for making good presentation of my demo here. The 2nd post is actually the idea.

Ajax Enabled Gridview using JavaScript in ASP.NET

  
Before explaining the article, I would like to thank all readers who read my article and voted for it. Your appreciation for my article gives me strength to write more good articles. Hope in future I will get your valuable comments and suggestions. Now I won't waste your time and come back to the topic. I have written this article on 'Ajax Enabled Gridview Using JavaScript in ASP.NET'. In this article, I will show you how to make a Gridview using a simple HTML table, JavaScript and XML HTTP for Ajax call without using any ASP.NET control.

GridView Javascript Click Row and Ajax

  
This article shows 2 common tasks with the ASP.NET GridView: Binding a List (generic) of objects as DataSource and on clicking a row, getting the values of the selected row by a javascript function. In the example a List with User-objects is displayed. On clicking a row containing the data of a User-object, the Id of the object is used to get the address of the user by an Ajax-call and display it in a details-field.

GridView Sorting/Paging : 'REAL' AJAX with Asp.Net Series

  
This is a continuation of my 'REAL' AJAX with Asp.Net (not Asp.Net AJAX) series posts for those of us trying to stop relying on Asp.Net 'AJAX'.

Ok, nothing too dramatic to start things off, we are going to make some tabled data sortable and pagable all without using a bit of postback. Not only that, but it is going to be incredibly easy!

VWDE 2010 Won't Install Ajax Control Toolkit on XP Pro

  

To my displeasure I cannot find VWD2005 which at one time would generate a complete web.config for Ajax so I downloaded and installed VWDE 2010 to a clean install of XP Pro.

I've created a new tab on the toolbar for the controls but after I select the Ajax dll to add the controls to the toolbar it grinds away and then goes poof and closes down the task leaving VWD look as if I had never even created the tab in the toolbar. 

 

Any advice here?

GridView: Move Over DataGrid, There's a New Grid in Town!

  

When incorporating the ASP.NET DataGrid control into your Web apps, common operations such as paging, sorting, editing, and deleting data require more effort than you might like to expend. But all that is about to change. The GridView control--the successor to the DataGrid-- extends the DataGrid's functionality it in a number of ways. First, it fully supports data source components and can automatically handle data operations, such as paging, sorting, and editing, as long as its bound data source object supports these capabilities. In addition, the GridView control offers some functional improvements over the DataGrid. Here DataGrid expert Dino Esposito introduces the GridView and explains all its long-awaited features.

Building a Custom Data Grid: Performing Ad Hoc Web Reporting with a VBScript 5.0 Class Object

  

A flexible, customizable grid for displaying data is a useful tool for ASP developers. It allows Web visitors to customize their view of your data. This article takes the data grid presented in "Ad Hoc Web Reporting with ADO 2.0" by John Papa and Charles Caison (MIND, December 1998) and adds handy features such as a finds feature that supports multiple finds and a mode for adding and editing records. This version also improves response time by allowing asynchronous record download and it componentizes the code so it can be used as a standalone VBScript class object that can be reused in other pages.

Think that there is actually errors in ajax toolkit for 2.0 framework...hmm

  

Im using VS2008, asp.net C# 2.0.

 

Recently i tryed to correct some stuff on my page and i had a friend to take a look at the stuff...

 

What i did was that i have Examples page with code examples. Then accordion panes for each code piece...And syntaxhighlighter for each code piece. The code that i presented is read from the txt files wich makes it easyer for me to put new examples on the site...

But the problem is now that two of my accordion panes are not working...and everything works in all other browsers this just happens in Internet Explorer. This is kind of weird and my friends explaination was that there is actually errors in the ajax toolkit dll.

 

Im using the latest version of ajax toolkit for framework 2.0 wich is 1.0.20229.

My friend said its actually amazing that the toolkit has been out there for that long and it has not been tested that well and that there i still errors in it.

 

You can test this by your self by doing the exact as i explain:

 

go here: http://www.simpa.dk/Examples.aspx?cookieCheck=true

click Csharp

and try to open the accordion that is from the bottom 2 or 1 they dont collapse...

but this works in all other browsers then Internet Explore
