您好，rohit，

您能否尝试以下解决方案，我认为这是您所需要的.
添加Div元素以进行Ajax加载程序图像处理.

Hi rohit,

Could you try the following solution, i think this is what you need.
Add Div element for Ajax loader image processing.

<div id="ajax_loader">
            <img  src='@Url.Content("~/Areas/images/mozilla_blu.gif")' style="padding-left:40px;" alt='' /></div>

为Ajax加载程序中的隐藏和显示"添加javascript方法.

Add javascript methods for Hide and Show in Ajax loader.

function UpdateShowPanel(UpdateMessage) {

( " ).show(); } 函数 UpdateHidePanel(){

("#ajax_loader").show(); } function UpdateHidePanel() {

(" #ajax_loader").hide(); }

("#ajax_loader").hide(); }

然后在要显示或隐藏的地方调用此方法.如果您使用的是更新"面板
只需调用UpdateShow方法即可.

Then Call this method where you want to show or hide. if in case you are using Update panel
just call the UpdateShow method only.
