General Help and support

For sometime now, many people have been posting comments on my blog entries for general help and support, not related to the page where the comment has been posted.

I appreciate people seeking help, and I try to respond to the questions in the shortest possible time. However, posting unrelated comments on blog posts tends to distract others from the actual content of the post. And I would like to keep comments on blog posts strictly related to the content of the post being discussed.

So, I have created brand new forums for General Help and Support at the website for my technical training institute, Imbibe Knowledge Enterprise. You can find the forums here. I will be providing active help and replying to questions on the forums. Further, I will try to get some of my experienced friends also to participate in the forums and provide help.

So, from this point onwards, I would request all visitors on my site seeking general purpose help to please go the above forums. I would request you to kindly keep your comments on this site related to the page on which you are posting your comment. I might delete any comment that I consider unrelated to the page content.

Many of the people come to my blog for questions related particularly to Coolite/Ext.net and ExtJs. So, here the the links for the Ext.Net/ExtJs forum:

Ext.Net/Coolite: http://ike.co.in/forum/net/extnet
ExtJs: http://ike.co.in/forum/web-engineering/extjs

I thank you all for your understanding.

Hi Rahul,

I am trying to assign dynamically created tpl to combo but i am not getting solution for it. You can find details of question at http://stackoverflow.com/q/16828766/2393573. Please suggest me best answer.

Thanks...

I am developing a windows application using c# as front end and SQL server 2005 as back end.

I have grid which shows values from database. My task is to update values in grid if and only if values in database changes.

I have tried thread, sqlDependency and signalR though it is for ASP.NET. I have also studied observer design pattern but i didn't understand exactly what id does. I have also tried event notification and service broker

In both the case grid keeps refreshing which is not desired. Is there any way to solve my problem?

Hi Sandeep, you can use polling on client-side to refresh data every few seconds. However if you need real-time updates, then off-course the combination of SqlDependency and SignalR is the right approach for pushing data to the clients. Off-course there are other ways too to accomplish the same, I advise you seek hold on other online forums.

Woah! I'm really enjoying the template/theme of this website.
It's simple, yet effective. A lot of times it's challenging to get that "perfect balance" between superb usability and visual appearance.
I must say that you've done a great job with
this. Additionally, the blog loads extremely fast for me on Chrome.
Superb Blog!

Hi Rahul,

I am working on developing a UI for file upload in EXTJS. I am trying to use the file field code to develop the UI for browse and upload columns. I am able to select the file(browse button) and then I am trying to hit the Upload button. 

I am stuck at sending the file to the server side. I am using this code to submit the form - 

var form = this.up('form').getForm();
           
if (form.isValid()) {
               
// Submit the Ajax request and handle the response
                form
.submit({
                    success
: function(form, action) {
                       
Ext.Msg.alert('Success', action.result.msg);
                   
},
                    failure
: function(form, action) {
                       
Ext.Msg.alert('Failed', action.result.msg);
                   
}
               
});
           
}

But the problem is that the file is not getting attached in the form and so no file is received on the server side.

I would really appreciate any help you can provide.

Thanks,

Keshav Ray
