Dynamically Adding a Column at the End

sobersp

Hi Grp

Can anyone tell me or point me to any specific topic in forum which describes how to add a Column Dynamically

I am adding a Column at the Begining of the table as described in,

http://datatables.net/examples/server_side/row_details.html

-in the CallBack but am not able to figure out how to add a Column at the End....

Thanks

Hi sobersp,

DataTables doesn't really allow columns to be added dynamically. The example you posted shows how to add a child row, is that what you were meaning? It is possible to hack around the lack of dynamic column support in DataTables, but it's not really recommended practice... :-)

1st'ly Thanks Allan for your reply...

The Problem I was facing was in IE-6 to add a Column at the End, Similar to what is done in the above example
In Above Example you are adding the 1st Column (Action Col), Similarly I need to add one more at the End....
I got around it, but my problem is, even after unbinding the 'Click' event, I face Browser Freeze problem
After some time the browser freezes....Note : I refresh the Page every 5 secs using fnRedraw...
Sorry if this is a jQuery/JavaScript kinda question.... but thought if you can add some light to the issue, ...!!

Alternatively, what do you suggest when you are doing Server Side Processing to Add a Action Column, Best Practice for DataTables... ??

Thanks VeryMuch
Sobers

Hi Sobers,

One thing that is very important when dealing with events and DataTables, particularly when adding and removing rows (this is what happens effectively with server-side processing or reloading an Ajax source), is that the events which are bound to the elements in the table must be unbound, otherwise you will run into a memory leak situation. Have a look at this post (and the thread in general) which might help explain this a little more: http://datatables.net/forums/comments.php?DiscussionID=643#Item_6

This is what I think you will be running into if it works to start with, but freezes later on.

Hey Allan

Thanks for the Quick Reply. I did try the link and try to Unbind the Click Event. I also tried to add a Alert Box in the loop to check if it actually gets called, and it does, for the number of rows in the table... Maybe I am doing something wrong. I will post the code soon in reply to this thread and you can check if any thing seems goofy...

Thanks a loot for your help....Need to buy you a beer
