Hello aniligatepatni , 

If the pane is loaded initially and you later decide to manually load some content url inside it the whole pane won’t re-rendered. Just for the iframe inside it a src will be set so that it will load what you’ve set for the contentUrl. To resolve this you can get the iframe and wait for it to load its data . Once it loads you can get the content’s height and set  that as the minHeight of the webtab.

Please refer to the attached sample and let me know if this would work for your scenario.

Hi Maya,

Thanks for ur reply.

even though if we set content pane auto size property to true still its not working. Here we are setting set_contenturl in javascript at run time .
