Asp.net| problem

1. In the process of submission is very long, in order to prevent users from clicking again and for the sake of the interface can be a layer to cover all the buttons to display a message, and so on server-side processing completed and then navigate to the page (location.href= ' address ') can be:

<div id= "doing" runat= "style=" z-index:12000; left:0px; Visibility:hidden;  width:100%; Position:absolute; top:300px; height:100% ">
<table width= "100%" height= "100%" >
&LT;TR align= "center" valign= "Middle" >
<td>
<table width= "169" class= "Font3" height= "bgcolor=" #6699ff "style=" Filter:alpha (opacity=75); width:169px; height:62px ">
&LT;TR align= "center" valign= "Middle" >
<td> page submission, please wait <br>
Please wait
</td>
</tr>
</table>
</td>
</tr>
</table>
</div>

Pageload inside so write: this. BUTTON1.ATTRIBUTES.ADD ("onclick", "document.getElementById (' doing '). style.visibility= ' visible ';");
, such as the completion of the operation after the redirect page reload, this layer also disappeared ...

Page.smartnavigation Property
Gets or sets a value that indicates whether smart navigation is enabled

True if smart navigation is enabled, otherwise false.

Note
In most cases, do not set this property in code. Set the SmartNavigation property to True in the @ Page directive of the. aspx file. When the page is requested, the dynamically generated class sets the property.

When an Internet Explorer 5.5 or later browser requests a page (or shortly), smart navigation improves the user's ability to manipulate the page by performing the following functions:

Eliminates flicker caused by navigation.
Keep scrolling position when moving from one page to another page.
Keep the element focus between navigation.
Only the state of the last page is kept in the browser's history.
Smart navigation is best suited for asp.net pages that require frequent postbacks but that do not change significantly when content returns. Consider this carefully when deciding whether to set this property to True.

[C #]
void Page_Load (Object sender, EventArgs e)
{
This. SmartNavigation = true;
}
void Button_Click (Object sender, EventArgs e)
{
label1.text= "<b>the value of ' SmartNavigation ' property is </b>" + "" + this. SmartNavigation + "'";
}

It still has a frameset at the very outside. You can notice that the difference with Ajax is that there is a flashing blue progress bar under the window (I really hope ie can get rid of this). Actually, it's simple, just a few seconds! is to set the property SmartNavigation of your page to True

Using the validation control, compile-time prompts "Unable to find the script library ..."
Workaround:
Because the home directory path has been replaced, the Aspnet_client folder under Wwwroot should be copied to the new directory
