How to call a javascript function in content place holder when the content place holder refreshes?

[Varun Sareen]

I have a content place holder in which there is a print button which creates a notepad file on the click of it for the records which are selected (checkboxes) in the grid view. The print button is placed in a

tag and the tag is hidden by default on the load of content place holder. A javascript code is called on the onclick event of the checkbox in the grid which makes the

for print button visible (if any of the checkbox is checked) and hide it when all the checkboxes are unchecked. The problem I am facing is that when I click on the print button then some events occurs and the content place holder refreshes and hence the

tag for the print button gets hidden although the checkboxes already checked remains checked only. Now what i have done is: I have made the

tag visible true always and looking to write a javascript code for making the

tag invisible while the grid is not filled. But I am wondering that where should i call this particular javasscript code? If someone could help me out? Thanks Varun Sareen

You would obviously want to call the javascript on the checkbox click events. You of course need logic to validate each checkbox's status and show/hide the button appropriately. I would recommand looking at JQuery[^]
