In research of a javascript library to be used with ASP.NET on my next project…

Leave a reply

Hi fellow readers,

Today I come to share with you how I choose a javascript library to be used on my new project.

I’m not talk about choosing just an AJAX library but I want some ‘full’ set of library which including both AJAX core and user interface core.

Here are my choices before consideration…

  • jQuery
  • YUI (Yahoo User Interface)
  • ExtJs

Sorry that I didn’t included other libraries because I’m not impressed with any other at all.

First, jQuery, this is by far the best AJAX + effect library for me personally. I really love it because it produces a ‘short’ script. Especially when compared to YUI.

However, what jQuery lack of is UI components. You have to find out 3rd party for yourself.

So, I decide to move on YUI which currently have a bunch of UI components included.

What I can say about YUI is I really impressed with it. It has a BUNCH of UI included in the library which you can select to use or bypass.

However, most of the script produced by YUI is so ‘long’ when compared to jQuery.

So, now, I hold on both YUI and jQuery and finding for a better library in the market.

I finally found ExtJs.

Try yourself and let me know how you feel about it.

I feel the ‘MOST’ impress with ExtJs.

Cool UI and effect and I decided to use it in combination with jQuery.

This will help me reduce much time to develop my project.

Technical details will be continued in the next part while I’m developing my project. :D

Talk soon,

Why you need validation in your web application?

Leave a reply

Hi folks,

Did you ever use ASP.NET validation controls?

If you never heard or never use it before, see on the toolbox at the “validation” group.

Those are all validation controls.

- RequiredFieldValidator

- RangeValidator

- CompareValidator

- RegularExpressionValidator

- CustomValidator

- ValidationSummary

The main point of this control group is to be used to validate the input form entered by user before doing any postback.

But why?

As we can implement validation easily in code-behind.

Right?

It had to say Yes and No.

Yes, because validation coding in server-side (code-behind) is easier to code.

No, because while you know at the client that the data is invalid. Why you will let user postback to server?

Waste of bandwidth.

Totally waste!

This is the main reason why you have to use validation controls in your web forms.

Because it’ll help to reduce the unnecessary roundtrip between client and web server.

This will not affect much on the application that consumes less resource.

But it will be a big pain on the application that consumes much resource.

So, when you are dealing with input form.

Always use validation controls!

I know it will help you much.

Why my .style.left doesn”t work with FireFox?

14 Replies

This is a simple & stupid knowledge that I taken about 2 days to solve it.

I have a project that have to use this code….

var con = document.getElementById(“menu”);

con.style.left = “10″;

con.style.top = “20″;

When I run this code in Internet Explorer 6, 7.

I got it working like I want!

But when I try with Mozilla FireFox.

It never works!

Man! I hate DOM, if I have enough money. I’ll buy Microsoft and stop Internet Explorer project to reduce browser compatibility issues. :-)

I try to use FireBug to change the css real-time, it does work very well.

The key point of this issue is that YOU MUST APPEND the property with UNIT!

I changed the code to…

con.style.left = “10px”;

con.style.top = “20px”;

And now it works!

Gotcha!

Simple & Stupid, right?

Use JavaScript to change “float” style

14 Replies

Hey friends,

In a few days ago, I’ve just stuck with how to change “float” style in JavaScript and very confuse why it doesn’t work at all!

I’m using …

var obj = document.getElementById(“some1”);

obj.style.float = “left”;

No luck at all. I tried both on Internet Explorer and Firefox. Even I use Internet Explorer Toolbar and Firebug. I can change the style via that tools but no luck with JavaScript.

Silly?

I’m fool with DOM. I try to find a solution and suddenly found that.

In DOM, there are no “float” property but “cssFloat”.

Just change my code to …

var obj = document.getElementById(“some1”);

obj.style.cssFloat = “left”;

Really silly huh?

What experiences you faced?

As I’m dealing with cross-browser web development project where I generally strict with XHTML 1.0 standard. (As I’m using Microsoft Visual Studio 2005 and there is built-in XHTML 1.0 validator. Also, it has a built-in CSS validator too.)

I generally focus to most popular browsers including Internet Explorer 6.x, 7.x and Mozilla Firefox 2.x.

Below is my experiences and how I handle the project after I failed one. Yes, I failed one! Don’t get wrong like me! It waste your valuable time.

Great 3rd party Ajax control suite

Leave a reply

Have you ever tried Ajaxify your ASP.NET application? Have you tried and tired?

I’m one of those guys who already tried and tired on ajaxify the application to fully working in Ajax basis. Until the day I found one of a great Ajax control suite named Telerik RadControls for ASP.NET. It was combined by various ASP.NET UI controls. Most of the controls, I can say nearly 100% already ajaxified for your instant using without deep knowledge on Javascript writing.

I found that my productivity was much increased by this suite and their support are great as I never seen this support anywhere even the more famous controls suite like Infragistics NetAdvantage, ComponentArt, ComponentOne or any other else. You can get quick response back within 24 hours with many samples on your desired case. So, for me It doesn’t a hard decision to afford it for 1 year subscription. After I’ve purchased, I found the bonus are very impressive as Telerik give us many interesting things than I thought. In my case, I purchase Telerik RadControls for ASP.NET with subscription for 1 year. I got Telerik RadControls for WinForms too. After purchase date around three months, Telerik releases new version of Telerik RadControls for WinForms with WPF. (Windows Presentation Foundation) and they give me too! What’s a kindly guy! In next six months, I found that the product was continuously updated around 4 times with many new features. Again, when they release their Telerik Reporting product. I also got it from current subscription and I thinks this reporting product are compact, fast and very easy on deployment. (I kicked out Crystal Reports, Microsoft Reporting Services and even DevExpress’ one – Every products I listed here are required to install some special executables into web server but Telerik’s just use XCOPY method)

If you are finding for a great Ajax controls suite. I can say that you will got the point when working with Telerik’s suite. Very very impressive!
