"Smart" CheckBoxSelectionModel

[brenda]

Use the latest version (1.7) and make sure the header you send in looks something like this:

<div id="x-grid3-hd-checker">&nbsp;Ref</div>

Cheers!

Thnx Noah
I've followed your advice and customise the CSS a little with 2 images that I've split from the original one (row-check-sprite.gif) to obtained the following output:


I've attached the little CSS codes that I've customised and the images:

.x-grid3-hd-checker{
    background-image:url(../images/row-check-sprite-uncheck.gif);
    background-position:23px 1px;
}

.x-grid3-hd-checker-on .x-grid3-hd-checker{
    background-image:url(../images/row-check-sprite-check.gif);
    background-position:23px 1px;
}

hi,

I have used this smartcheckboxselectionmodel and i need something like below..plz tell how to do that..

I need to catch event listeners when i select a row and another event listeners when i check the checkbox(as well as when i uncheck)...if i use something like that
listeners:{rowselect:myFunctionOnSelect} , then both rowselect and checkbox check call the same function. how can i detect if it is row select or checkbox check?

I have configuration email:true.

I see what you mean. Give me a few hours and I'll post an update that will suit your needs. Cheers!

Any ideas how can I make the Ext.grid.SmartCheckboxSelectionModel work using a remoteSort in the data store? Seems to me that I either have to send (via ajax) the status of a checkbox every time I check/uncheck or save the state of the of box using a unique id for the checked boxes....... or
Thanks you.

If there is no paging, then using a remote sort should work out of the box. When you throw paging into the mix, you either have to use a Cookie/HTTP provider, and/or save the state of the checkboxes as they are clicked, and if that's done, you can comment out one or two lines in the SelectionModel to properly check the boxes again based on the store data.

I could help you out with that part if you go that route... or if you come up with another method, I'd love to add your code to the SelectionModel

@nb: Haven't had time yet to complete your request, but it's on my TODO list this week. Cheers!

I also need paging (I have ~56000 rows) so the idea of a Cookie/HTTP sounds the way to go. Let me know once you get the chance to implement it.
Thanks again.

How can you identify each row? If you have a column in your data that is unique then there is no problem otherwise ..... hmmm...

store the page no. somewhere.
all that's needed then to uniquely identify a row (without the need for ids), assuming your sort order doesn't change, would be this formula:

var virtualRowId = (pageNo * pageSize) + rowNo;

[imnphd]

That ain't gonna work as you said if you sort the grid.

duh.
it's a mere alternative in the unfortunate event you don't have unique row ids.

if you dislike that you could md5 all Fields in a Record and use that as a row id.
and again the new assumption would be that none of the Fields are mutable.
