Hi Saki,
Thanks for sharing the nice techniques on ExtJS. As part of my new App design concepts I came across the link: http://www.sencha.com/forum/archive/index.php/t-71873.html
Where you mentioned that \’Have you seen my examples? They\’re tree on the left and ifram in the center.\’
If possible, can you please share/point me to sample code to implement the same.

Hi Saki,
Thanks for sharing the nice techniques on ExtJS. I have just started working on this nice framework. I am trying to use it in my new application, which has lot of main and sub modules. When I am surfing for some design concepts I came across think link: http://www.sencha.com/forum/archive/index.php/t-71873.html

Hi. Thank you for your articles.
Can you tell how to destroy ext components correctly? I have faced with a lot of memory leaks.

Thanks.

P.S. Sorry for my English.

I\’m curious, why is initComponent not documented in the Ext API reference? It seems like it appears in quite a few examples but isn\’t officially a public API.

Post please your question to forum and PM me the link to it. I guess many others can face the same problem so better would be to answer there.

Hi,Thanks for the article.I appreciate your help always.
I have 20-25 grids in my app.all with different fields in store and different column headers in column model and also different context menus.I am using EditorGridPanel for some and just GridPanel for others.
Do you think extension of grid panel is needed here ,can it help in avoiding to write 25 column models and store.and provide a generic way to enter store and context menus and column headers?

If you move panelConfig to initComponent then it is not in prototype and it will work.

Maybe it's not formulated exactly but if you do not plan to reuse a component you do not need to extend. However, if it better suits to your app, programming practices, file organization, etc, you can extend if you want if you do it properly and w/o mistakes.
