Way to hide it

Hi,
I want to change visibility of relevant button (like to hide it), per given relevant values on the page. How?

<input type="button" id="butt_p4" onclick="openPopup4();" style="height:23px; width:97px; visibility:visible" value="删除照片" runat="server" />

Open in new window

to hide a control that runat=server, you can consider to adjust its Visible property.

like in your code behind, try:
if (yourLogic) {
yourControl.Visible = true; //or false
}

since the button is runat=server

you can consider to hide it by either front end via javascript OR back end via your .NET programming.
it's up to your workflow and method of handling it.
