GridPanel row spanning (well, sort of...)

[Condor]

The current GridPanel implementation doesn't support row spanning, because the rows aren't part of the same table.

The only thing you can do is make the grid look like it has row spanning by changing the css.

Example:

<style type="text/css">
.grid-row-span .x-grid3-row {
    border-bottom: 0;
}
.grid-row-span .x-grid3-col {
    border-bottom: 1px solid #ededed;
}
.grid-row-span .row-span {
    border-bottom: 1px solid #fff;
}
.grid-row-span .row-span-first {
    position: relative;
}
.grid-row-span .row-span-first .x-grid3-cell-inner {
    position: absolute;
}
.grid-row-span .row-span-last {
    border-bottom: 1px solid #ededed;
}
</style>

My requirement is to edit the multiple rows at a time in grid( without saving the each row after editing it)....

I need to allow the user to save all the changes in the grid with a save/update button ....
(button was at the end of the grid in bbar)

(I 'm using ExtJS4.0.1)

Thnx in advance!

Hi Condor/Aditya,
Could you guys post the example here or mail it to me. I am trying to create a similar editor grid, but i am facing a lot of problem.

Thanks.

I see a great example on how to do row spanning but I would like some help on cell spanning. I have a single row that needs to span across all cells. Is there anyway to do that. Attached is a screenshot.
