Use selectionMode as "single" and "multiple" for same table

[mitnpatel]

Hi,

I have requirement to use single selection and multiple selection on same table.
I have one table on left hand side of page and depending upon users selection (single row selection or multiple row selection) I need to update right hand side of page.
If user select just one row then I have to display view A and if user select multiple rows (more than one) then I have to display view B.

I know that in primefaces table i can have single selection or multiple slecetion mode on table but as per my requirement i have to combine both of same table.

Any idea how this can be achived ?

Thanks

I never really used the selection-feature of the datatable. but you could use multiple-selection and check if the number of selected rows is 1 or more and act accordingly.
would that be an option?

I am currently doing that but the problem with this aproch is :

When user selecet 10 rows and then he wants to select only one row then in order to do that he need to "Unselect" other remaining 9 rows first.

So form useablility prospective it not user firendly.

No thoughts about how to achive this ?

Hi mitnpatel,

I didn't totally understand why you need "single selection and multiple selection on same table". Try with multi-selection. If user selected one row - view A, if more - view B. The check is easy done if you process the table or use instant row selection. What is the problem?

Oleg, see my reply in the post I mentioned above. I describe the reason for this.

There is no built-in way, it is either one or the other unless you hack/extend it somehow.

unless you hack/extend it somehow.

Trying just that (in combination with shift-click), but new to jquery internals, so it might take a while (up to just before 3.0 GA e.g. )

Ok, I see. I have done this quite simple and user-friendly in one of my web applications (no PrimeFaces, Struts and my own table implementation). My proved approach is:

1) Selection is done either by checkboxes or row click.
2) By checkboxes you can select multiply rows. Rows are also highlighted.
3) By click on a row all previous selected rows get deselected. This is a single selection then.

See screenshots

Multi-Selection



Single-Selection (the same table)



Edit: And my context menu on a table (right mouse click) is aware of selected rows and is built up dynamically on the client-side only I'm missing that all in PrimeFaces, so that some hacks are needed in the future.
