Resize grid columns using css rules instead of element style

[anthony.fryer@…]

The current grid column resizing works by setting width in the style of every dojoxGrid-cell in the grid. It might be faster to apply a class to each cell in a column using a naming convention like ${id}_col(1..n) and just change the width of the css class when resizing columns.

Also it would be nice to have an active resizing option on grid columns.

Sounds like you might be solving a problem that doesn't exist (is column resizing slow now?), but if you did change it then wouldn't it be better to have a single CSS rule like this?

#myGrid1 col1 { width: 100px; }

(and every cell in column 1 has class col1)

I think in circumstances that are not all that uncommon grid resizing is definately slow. A grid with lots of rows and columns running in IE6 generally has poor resize performance, especially if you are scrolled down a bit from the top of the grid. The change to use dojo.dnd to do the resize has made the performance even worse.

I think a resize causes a complete re-render of the grid at the moment (could be wrong but am 90% sure it does), which involves generating the innerhtml for all visible rows. I believe that this is unnecessary when all that should be done is the existing nodes have their css class rule updated.

I think your way of using CSS for specifying column width is even better than my initial suggestion.

So it sounds to me that the issue has been solved by specifying column width. Agreed that grid resizing is slow - but those performance issues can be tracked in different tickets.

Closing this for now - as it appears to be a non-issue anymore.
