如何使用javascript使服务器端的表行可见？

Question

I am making a tr which runs at server side to invisible. But in some conditions,I want it to be visible.I am using the bellow script to make it visible:

 document.getElementById('trID').style.display = "block"

and also i used:

  document.getElementById('hidebuttons').style.visibility = "visible";

But it is not working. Please help me on this.

Answer 1

Once control is marked as invisible at server side, no mark-up (html) is emitted for it. So it cannot be made visible at JS, because it (corresponding html) does not exists at client side.

you can do something like

trID.Attributes.Add("style", "display:none");

then in javascript

document.getElementById('trID').style.display = "block"

NOTE : If you set the control visible=false in server side then it will not render at client side
