placeholder function

I have a table inside a placeholder. when i click a go button the table becomes visible. 开发者_JAVA技巧However when i click on a radiobutton list with autopostback property set to true, the table within that placeholder dissapears. Is there any way to make the table within that placeholder permanent once i have made it visible thru the go button?

how to make a table within a placeholder visible?? I am using

placeholder1.visible = true;
table1.visible = true;

but still its not showing up.. do i need to use any other property.? please help..

You need to ensure the visible state of the table is persisted through post back and restored when the page renders again.
