Hello All,

I am new to AJAX and JQuery.

In my web-application I have taken one page "MasterGroup.aspx".
On the page I have one GridView and below I have one button "Add new group".

Actual Problem

I want to show the form as popup form with background page is in in-active state.
So I created one more page "AddGroup.aspx" with one textbox and a save button.

But I am not able to show the popup as well as not able to inactive the background page.

Please help me.

Thanks in advance.

<asp:Button ID="button"  onclick=" openPopup();return false;" />

add this Javascript Code in head

<script language="javascript">
    function openPopup() {
        window.scrollTo(0, 0);
        var width = document.documentElement.clientWidth + document.documentElement.scrollLeft;
        var height = document.documentElement.clientHeight + document.documentElement.scrollTop;
      
 var layer = document.createElement('div');
        layer.style.zIndex = 2;
        layer.id = 'layer';
        layer.style.position = 'absolute';
        layer.style.top = '0px';
        layer.style.left = '0px';
        layer.style.height = document.documentElement.scrollHeight + 'px';
        layer.style.width = width + 'px';
        layer.style.backgroundColor = 'black';
        layer.style.opacity = '0.75';
        layer.style.filter += ("progid:DXImageTransform.Microsoft.Alpha(opacity=75)");
        document.body.style.position = 'static';
        document.body.appendChild(layer);
        var size = { 'height': 220, 'width': 750 };
        var iframe = document.createElement('iframe');
        iframe.name = 'Logic Form';
        iframe.id = 'popup'; //optional
        iframe.src = 'AddGroup.aspx’;
        iframe.style.height = size.height + 'px';
        iframe.style.width = size.width + 'px';
        iframe.style.position = 'fixed';
        iframe.style.zIndex = 3;
        iframe.style.backgroundColor = 'white';
        iframe.frameborder = '0';
        iframe.style.top = ((height + document.documentElement.scrollTop) / 2) - (size.height / 2) + 'px';
        iframe.style.left = (width / 2) - (size.width / 2) + 'px';
        document.body.appendChild(iframe);
    }       
  script>

Hope this helps.
