This is just an example.

C#

{

    background-color: White;

   filter: alpha(opacity=50);
    opacity: 0.7;

    z-index: 120;

}

XML

<asp:UpdateProgress ID="UpdateProgress2" runat="server" AssociatedUpdatePanelID="UpdatePanel2">
    <ProgressTemplate>
                  <div id="Imgt"    style="position: absolute;width:1030px; height:300px;" align="center" valign="middle" runat="server" class="blur">
                  <img src="ajax-loader (5).gif"  style="position:relative;right:100px" /><br />

                  </div>

Add this in the Webpage.

ASP.NET

<asp:scriptmanager id="ScriptManger1" runat="server" enablepartialrendering="true" xmlns:asp="#unknown">
    <Scripts>
        <asp:scriptreference path="js/Progress.js" />
    </Scripts>
</asp:scriptmanager>

Css for Gray out will be like this :-

.loadingPopup
    {
	    border: 2px;
	    padding: 4px;
	    border-color: Black;
	    position: fixed;
	    top: 50%;
	    left: 50%;
	    visibility: hidden;
    }

And Finally Add this Code in the Progress.Js File and add to the solution.

JavaScript

// "Grays out" and makes the screen non-interactive when performing an update.
// To show a graphic progress "spinner" or something put it into hidden element
// id="AjaxLoading" on your page.

Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(BeginRequestHandler);
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);

function BeginRequestHandler(sender, args) {
    showProgress();
}

function EndRequestHandler(sender, args) {
    hideProgress();
}

function showProgress() {
    grayOut(true, "");
    var spinner = $get("AjaxLoading");
    if (spinner == null) return;
    spinner.style.visibility = "visible";
}

function hideProgress() {
    grayOut(false, "");
    var spinner = $get("AjaxLoading");
    if (spinner == null) return;
    spinner.style.visibility = "hidden";
}

function grayOut(vis, options) {
    var optionsoptionsoptions = options || {};
    var zindex = options.zindex || 50;
    var opacity = options.opacity || 30;
    var opaque = (opacity / 100);
    //Setting the color
    var bgcolor = options.bgcolor || '#000000';
    var dark = document.getElementById('darkenScreenObject');
    if (!dark) {
        // The dark layer doesn't exist, it's never been created.  So we'll
        // create it here and apply some basic styles.
        tbody = document.getElementsByTagName("body")[0];
        var tnode = document.createElement('div');
        tnode.style.position = 'fixed';
        tnode.style.top = '0px';
        tnode.style.left = '0px';
        tnode.style.overflow = 'hidden';
        tnode.style.display = 'none';
        tnode.id = 'darkenScreenObject';
        tbody.appendChild(tnode);
        dark = document.getElementById('darkenScreenObject');
    }

    if (vis) {
        var pageWidth = '100%';
        var pageHeight = '100%';
        dark.style.opacity = opaque;
        dark.style.MozOpacity = opaque;
        dark.style.filter = 'alpha(opacity=' + opacity + ')';
        dark.style.zIndex = zindex;
        dark.style.backgroundColor = bgcolor;
        dark.style.width = pageWidth;
        dark.style.height = pageHeight;
        dark.style.display = 'block';
    }
    else {
        dark.style.display = 'none';
    }
}
// Needed for ScriptManager to load the js properly.
if (typeof (Sys) !== 'undefined') Sys.Application.notifyScriptLoaded();

In This Way i had done gray out the page .
