I got the following error, when I am trying to update or insert new records from an editable telerik grid. Some times it is able to edit, and insert new records, but many times it throws the following error. Please help me on this.
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500.

Hello,
I would like to know whether it's a good idea to use extJs framework to develop a large scale cross-browser business web application. I have looked at the various samples and the POC applciation done for us by a third party vendor and found that it requires to much of JavaScript coding, almost all UI elements are outputted using JavaScript. To me it felt like developing a GUI application using a notepad and without visual aid. I am also of opinion that such an application will be hard to maintain and will pose lot of difficulties in maintaining it for a long period. One of the counter argument on this was that for implementing top of the class interactivity this framework is a must and modern UI can not be delivered without the use of this particular framework. The in-house developer's have little or no JavaScript expertise. Following were the major considerations for selecting this framework were
- State of the art interactivity & usability.
- State of the art user interface full of widgets and drag and drop.
- Great looking personalized grids which allow column re-sizing, column hide, virtual paging.
- Flexible personalized site Layouts.
- Single page applications.
- No server side UI coding.
- High performance page rendering (no page refresh only JSON data flows)
Please post your thoughts. I have seen very little extJs related activity on CP forums and hence really curious to know your thoughts on this.
Regards,
Prasad P. Khandekar

This will concern me a lot as learning curve with ExtJs could be steep and long..

Hi Prasad,
Components provided by ExtJs are one of the best in the market and most importantly you will have access to the ExtJs forums where you can raise your concerns if any and or otherwise you can look for the solutions to your problems.
Another important aspect to be considered at this point is that ExtJs has provided with LOTS of good example and tutorials from where a newbie can learn and implement the controls of ExtJs.
I have been working with Sencha's ExtJs Grid Component (majorly) and believe me it is simply wonderful.
Now coming to your points, ExtJs provides you with the modern themes with good looking UI, you can work with AJAX proxy of ExtJs which will remove any postbacks to server and will enhance responsiveness of the application where you can RECEIVE data in JSON format.
Thanks,
Abhishek Sinha

I doubt many people will download your code and try it. I would recommend using jsfiddle.net instead.

Here is universal parser in javascript: http://synth.wink.ws/moonyparser/
I've been to hell and back to make it faster, but that's it, shift-reduce can't be much faster. Unfortunately, finding errors in text makes it three times slower. At least it has linear parsing time.

If you want to promote your code then please post an article about it as described in http://www.codeproject.com/info/Submit.aspx[^], not the technical forums.
Use the best guess

I am sure this has been asked a million times, but I am going to ask again because I can't find a good answer to my specific issue. I am using MVC asp.net and I want to load data through Ajax when a row in a Telerik grid goes into edit mode. I can get the data to load and everything is good, but I can't get the cascading drop down to work. Here is my change event code, the error is somewhere in here:
$(document).ready(function () {
$('#categoryId').live('change', function () {
var defects = $('#defectId');
if ($('#categoryId option:selected').val() != '') {
$.ajax({
data: { categoryId: $('categoryId option:selected').val() },
type: "GET",
url: '@Url.Action("_GetDefectsByCategory", "Observation")',
success: function (data) {
defects.dataBind(data);
defects.reload();
alert("Successfully bound.");
},
error: function () {
alert("Failed to bind defects.");
}
})
};
});
});
The alerts are there for debugging purposes, obviously. I am not natively a JScript person as I typically work in strictly OO Client-Server environments, any help would be appreciated.
Cheers, --EA

Seems like you're missing a # in the line here:
data: { categoryId: $('categoryId option:selected').val() },
Should be...
data: { categoryId: $("#categoryId option:selected").val() },

It should work. Could be a few of things: you have a setting for the .low class lower(further down) in your css file that is over-riding this value, or you have not used the .low class on any element or maybe even mistakenly used and id of 'low' rather than a class of 'low' on one of your elements. It also could be that you have a text setting lower in your css file that over-rides this. Really difficult to tell from one bit of code. Use the browser console to try and debug what is happening.

this class can be useful to you
.low
{
text-transform:uppercase;

Hi all,
i am beginner and learning. below my sample code. demo is working and demo1 is not , what the mistake i have done
<!DOCTYPE html>
<html>
<body>
<h1>My First JavaScript</h1>
<p id="demo1">
what the hell is going on.
</p>
<p id="demo">
JavaScript can react to events. Like the click of a button.
</p>
<script>
function myFunction()
{
document.getElementById("demo").innerHTML="Hello JavaScript!";
doucment.getElementById("demo1").innerHTML="This is not working";
}
</script>
<button type="button" onclick="myFunction()">Click Me!</button>
</body>
</html>
Thanks
Joe

You misspelled "document" as "doucment" on the "demo1" line.
If you look in the Javascript console, there should be an error message saying something like "doucment is not defined" - when something in JS fails to work, you should look there first.
