Default Non-displacement of controls when visible="false"

I'm not sure if this is a pro topic or beginner, but I have two buttons on my page. One will always be visible, the other not. Basically, one is to view hidden content on a page (it will be a bound description of data that will appear on a click) the other button is to hide the description. So, when you click on the "show" button, you see the content and it's visible="false" and the "hide" button becomes visible"true" (and vice versa).

The problem I am trying to work out is -- How can I make the "hide" button appear where the "show" button was?

In my code for the page, I have both buttons...

<td>
<asp: button id = "show"/>
<asp: button id = "hide"/>
</td>

Is there some sort of trick or displacemenet property that VS isn't showing?

Thanks,
Rob

When you set the Visible property of a button to True, it's invisible at the server. This means it's never sent to the browser at all.

This is different from CSS's visibility property that *hides* an element while it still takes up the screen estate it would have if it was visible. To some extend, Visible in ASP.NET behaves like display: hidden in CSS where the hidden element isn't visible and doesn't take up screen estate.
However, the difference is that with CSS the code for the element is still present in the HTML, while for a server side control it isn't.

There are a few ways around this:

1. Create a table with two cells and a fixed width. Put the button in the table cells. When you hide one, the original table space stays the same, so your button stays in the same place.

2. Use CSS to move the other button. Let's say you have a Save button and a Cancel button and you want to hide the Save button:

btnSave.Visible = False
btnCancel.Attributes.Add("style", "margin-left: 75px;")

This code adds a style attribute to the Cancel button, telling it to move 75 pixels to the right. That way, it moves to the right, leaving the desired space.

Does this help?

Thank you! I am also going to try to put the button in a form that is hidden. The form will have the appearance of a POP-UP, (as it will be absolutely positioned on the top), and it will have it's own button that will "hide" the form when clicked...Might be better to appear like a "window"....we'll see.

I really appreciate your help!

Regards,
Rob
