Swapping of controls on a web form (mirror image) (ASP.NET)

HI All!!
 I am developing an application in ASP.NET (code behind VB.NET) and one of the main functionality of the page is that on clicking of a button on the page, a mirror image of the page is shone (all the controls on the page are swapped eg. All controls from right to left will now be left to right).
 Could you pls give me the codes for doing this? it would be great if I could get codes in VB.NET

When you generate the page give the body an id:

<body id="bod">

Then the control looks like this:

<input type="button" value="mirror image"
onclick="document.getElementById('bod').style.direction='rtl'">

Do you mean make the text you enter have its direction reversed, or do you mean:

[button1] [button2] [input3]

when you click the switch button/link, it becomes:

[input3] [button2] [button1]

?

You could probably use a div around each form element, then position each div with CSS.  

   <div class='css_class1' id='div1'><input type='text'></div>

When you want to reposition the fields, use javascript:

   div1.class='reversed_css_class1';


Note: this wouldn't be very scalable - you'd have to change the code if you changed the number of elements on the page.

A better implementation would be to parse the DOM of the page, then rewrite it with the form elements in backwards order, but I'm not a DOM expert so css is how I'd do it :-)

And actually, if you're of the "css=layout" "html=data" school of thought, then my first solution is actually better than messing with the DOM with javascript.

As I said, this isn't very scalable, but it works:


<html>
<head>

<style type="text/css">
.boxleft
{
position: absolute;
top: 100px;
left: 50px;
background-color: blue;
color: white;
}

.boxmiddle
{
position: absolute;
top: 140px;
left: 100px;
}

.boxright
{
position: absolute;
top: 180px;
left: 150px;
background-color: red;
color: black;
}

}
</style>

</head>

<body>
<input size=10 id="aa" type="text" class="boxleft" value="a">
<input size=10 id="bb"  type="text" class="boxmiddle" value="b">
<input id="cc"  type="button" class="boxright" value="c button">

<input type="button" value="orig" onclick="javascript:aa.className='boxleft';cc.className='boxright';return false;">

<input type="button" value="switch" onclick="javascript:aa.className='boxright';cc.className='boxleft';return false;">


</body>
</html>

Actually cobols works pretty darn well too, as long as you don't have elements positioned with CSS:

<html>
<head>

<style type="text/css">
.boxleft
{

background-color: blue;
color: white;
}

.boxmiddle
{
color: purple;
font-weight: bold;
}

.boxright
{

background-color: red;
color: black;
}

}
</style>

</head>

<body id="bod">
 <input size=10 id="aa" type="text" class="boxleft" value="a">
<input size=10 id="bb"  type="text" class="boxmiddle" value="b">
<input id="cc"  type="button" class="boxright" value="c button">

<input type="button" value="orig" onclick="document.getElementById('bod').style.direction='ltr';return false;">

<input type="button"  value="switch" onclick="document.getElementById('bod').style.direction='rtl';return false;">

</body>
</html>


If you have elements positioned with CSS, the CSS will override the style.direction, and instead only the text-direction inside the input boxes will change.

Break the inheritance; of course.  If you have cascades, you have to maintain them.  It is no different for any CSS property they have scope, contraints and inheritance characteristics.


You can scope it from a single element to a page, and you can overlay the styles to ge twhatever effect you want.  That is a primary reason for using CSS.
