listgrid with hyperlinked field

[iainc.dev]

I'd like a column in my listgrid to show data (numbers) that appear hyperlinked (eg blue, underlined). When a user clicks on it, I need to be able to trap this "click" event and do something with it. I will usually have only about 1000 rows of data, but on rare circumstances, I may have 10,000 or even 100,000 rows of data.

My solution is to use the "clickhandler" for listgrid cells combined with a cellFormater in which I will prefix the value string with the html codes for making the text blue and underlined. I could alternatively use SmartGWT HILITES.

Is this the best approach? I intuitively feel that there might be a better perfomant way to define a cell's formatting for the whole column without having to invoke the cellformatter logic for each and every data value. That said, it may not be that big of a performance penalty for 1000 rows or even 100,000 rows. Any advice would be appreciated.

There's a built-in ListGridFieldType "link" that might be able to handle this for you. However, if there's some nuance of how the links appear that you want to be different, doing this via a CellFormatter is fine, and shouldn't have a noticeable performance impact over fieldType:"link".

Note that even with 100,000 rows, your formatter is only going to be invoked for rows visible in the viewport (and a small predrawn area controlled by drawAheadRatio).

I already started using "clickhandler" for the whole listgrid. That said, if I were to use the "listgridfieldtype" of "link", how do I interecept the "link" to run a smartgwt piece of code instead of opening up a new url-based window.

Take a look at the docs for ListGridFieldType "link" - all your different options are described right there.
