Question

I have a Div with runat attribut="server" .I have an asp.net button control in my page,When this button is clicked,I want to hide the div.Is there any other option that changing visibility to false.I cant use the visibility to false,because when i change visibility,I cant access the same in my javascript since it is removed from the browser.I want to Show that hided div from my javascript

Any thoughts ? Thanks in advance

Answer 1

Add a display:none CSS style to the control:

myDiv.Style.Add(HtmlTextWriterStyle.Display, "none");

Is there any other option that changing visibility to false.I cant use the visibility to false,because when i change visibility,I cant access the same in my javascript since it is removed from the browser.

This doesn't make sense. Setting the CSS visibility to hidden will not remove the element from the DOM.

Answer 3

If that's the only thing your button does, I'd probably do it in javascript first to avoid the postback all together.

If that's not an option, then just add the style attribute to the div server-side with "display:none;" for the value.
