Hi guys

I'm writing an app with MVC 4, and I'm dynamically building a table. The table is to be clicked to display things related to the selection in a window below the table.

To show the user which they have selected, I am setting the CSS class on the selected row so that it is styled differently. This works great, BUT I don't know how to reset all the other rows in the table so that there is only the one differently colored row.

Can anyone help?

I thought I could use javascript to iterate through the rows, but I can't figure out how to use this to set the CSS class?

Thanks

Doesn't matter. A case of exhausted brain and hunger.

After some curry, and a few swigs of Red Berry Cider, I realised I was being dumb...

In case anyone else gets logic block on this, here is what I did.

I simply had a variable to contain the item I clicked on so that I can look at it later. Set this during the routine. Then next time I fire the routine, use it to change the old one back to what it should be.

var prevItem;

        $('.update-list-item').click(function (e) {
            if(prevItem != null)
                $(prevItem).removeClass('update-list-item2').addClass('update-list-item');

            prevItem = this;
            $(this).removeClass('update-list-item').addClass('update-list-item2');
        });

I'm off to bed now...
