[coollife]

What is the use of place holder and can we use it as an pop up window

[dnanetwork]

instead of placeholder you can think of panel control or much lighter html control div...

all you need is a little javascript and you are done..

in google you can search for hiding panels/div..

hope it helps.

PlaceHolder control serves as container to add controls dynamically to a web page at run time. The PlaceHolder control does not produce any visible output and is used only as a container for other controls on the Web page.

Therefore you cannot use it to show popup window.

You can use DIV to show a popup using CSS layers and javascript.
