I can not seem to control the width of asp.net controls within customItems.

I am dynamically generating a treeview where each treenode is associated with a unique CustomItem. I am not having problems populating the nodes or node groups. Every treenode is associated with a unique customItem. Every customItem is populated with a couple of labels, a couple of small images and a couple of link buttons. All these controls have the correct text and images.

I have assigned css classes to each asp.net control and associated a css with the web page. With the associated css I can change colors and fonts but I can not change the margins of these controls, ie I can not vary the spacing between controls. In fact, I always get the same tight result even if I change the width property of the controls themselves.

I have colored the backgrounds of both the customItem control and the treeview to demonstrate that plenty of room exists.

Any idea why I can not control this aspect?

TIA

Whoops! Seems asp.net or IE has to see units on lengths in css. I thought there was a default to px but seems there is not. Worked once I put px units in. Thanks again for the very quick replies: it really helps projects move.
