Localize time out error message of asynchronous postback in ASP.NET AJAX

Urs Enzler30-Oct-07 22:46

hi folks.

When a asynchronous postback (ASP.NET AJAX) times out then the ClientScriptManager shows a dialog with the error message: Sys.WebForms.PageRequestManagerTimeoutException: The server request timed out.

Does anyone know how this text can be localized?

Note that this is not the same as when a asynchronous postback throws an exception. That can be handled with the ScriptManager_AsyncPostBackError event and a custom error message can be sent to the client.

happy programming
Urs

This is a tetchy issue...

for security reasons you can not launch an EXE from ASP .net on the client side (... any hacker could just launch evil exe's).

But... if you can:

- If you want to just pregenarate an Office doc, you can send it as an stream to the client setting the content file to Excel or Word, it will open the excel file on the client side, maybe embedded on the nagivator.

- If you want to open an empty excel file you could send that as an stream (An empty excel file), following the same approach as the previous bullet.

- If you need to be able to execute the exe and you are on an intranet, on possiblity could be to have an ActiveX control that is installed on the client machine, BUT That's quite risky, I won't do that (security hole).

Yes, that will work, as would putting it in a hidden field that is a server control. What does your code look like ?

i think this value that you are initialzing in javascript won't persist.
Do one thing Add hidden variable runat server and assign value to that hidden varaible and use that hidden varaible at server side like this

 var label1=document.getElementById('hidden');<br />
<br />
       label1.value="Sandeep";<br />

and at the server side just get the value from it
hidden.Value that will return you string

OK don't add ToString();
just add
string val=txtHidden.Value;

And be sure that txtHidden is decalared in your application such as
System.Web.UI.HtmlControls.HtmlInputHidden txtHidden;

Check the id of the hidden control in aspx page and aspx.cs both should be identical.
Could you post your whole page ?

Please be sure that txtHidden value is assigned in aspx
Code looks right check my code
this is javascript function

function HideContent()
{
var hiddenVar=document.getElementById('hidden');
hiddenVar.value="Sandeep";
}

And here is the .cs file code

protected void Page_Load(object sender, EventArgs e)
{
Button1.Attributes.Add("onclick", "javascript:HideContent();");
}
protected void Button1_Click(object sender, EventArgs e)
{

if (!String.IsNullOrEmpty(hidden.Value))
{

TextBox1.Text = hidden.Value;
}
}

It is working boss in my machine

If this works, odds are that lblerr is not a server control. A server control invariably has a longer client side Id than it's server side one.
