Hi, Few tips to maintain the tabcontrol performance: 1.Do not drag drop many objects on to each tab.Instead used the user control and gives instances on each tab. 2.Check if you are loading data in all tabs each time a tab is clicked.(Page Posting back?). 3.Which tab control are you using ? asp.net or ajax? (put the tab control in ajax update panel to reduce the post backs) Hope this helps to figure out where it is taking more time to load. -Manognya __________________________________________________ $ God gives what is best.Not what all you wish :)
