Yet another suggestion about the famous javascript eval problem.

Hi !

I Included the "EvalScripts.js" .

But it is giving the following javascript error at

function js_registerJsEval()

{

Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(js_beginRequestHandler);

Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(js_pageLoadedHandler);

}

"

--------
Error
--------
A Runtime Error has occurred.
Do you wish to Debug?

Line: 59
Error: 'Sys' is undefined
--------
Yes No
--------
Do i need to include any other tags ?

Currently i included the following code

<atlas:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="True" />

<atlas:UpdatePanel ID="up1" runat="server" OnLoad="up1_Load" >

<ContentTemplate>

<table>

...

...

<tr>

<td>

<asp:Button ID="saveBtn" runat="server" Text="Save" ToolTip="Save Information To DataBase" OnClick="OnSaveClick" />

</td>

</tr>

</table>

</ContentTemplate>

</atlas:UpdatePanel>

In the onSaveclick() i am registering a Startup Java Script like

ClientScript.RegisterStartupScript(

typeof(HR_HINHrmDomicillaryTreatmentClaimForm),"round","alert('Saved Successfully');",true);

Please guide me further.

hello.

sorry, but i'm not following: what do you mean by updatepanels not evaluating javascript statements? if you need to insert or run jscript instructions after a partial postback, you should use the static registerXXX methods of the scriptmanager class.

Can you please give an example of how to do this?

I have custom control that is now within an UpdatePanel and none of the JavaScript that it registers with thePage.ClientScript.RegisterXYZ methods is getting loaded.

Thanks!

It not Atlas compatible.

Upgrade your Atlas to new ASP.AJAX.

I can use RegisterXXX methods, but many of third-party controls (for example telerik controls) not using this methods, and simply don't work together with ASP.NET AJAX.

Btw, now I develop new library (base Page class) that on Render method detects javascripts and register them via RegisterXXX methods.

You have some control in UpdatePanel and you want register some scripts in partial update?

1<asp:UpdatePanel runat="server" ID="ThePanel" UpdateMode="Conditional">2 <asp:Label runat="server" ID="TheLabel" />3</asp:UpdatePanel>and code behind:

1protected void InjectScript()2{3 ScriptManager.RegisterClientScriptBlock(TheLabel,typeof(Label),"TestBlock","alert('test')",true);4}
this works.
 
OR
 
you may use my script

I almust forgot about new version.

I think this is last javascript-based version.

This worked once I figured out the correct name space for ScriptManger which isMicrosoft.Web.UI.

Thanks!

Hmm... It's like that only I using third-party controls that don't work in UpdatePanel
(all others write all controls itself and use ScriptManager.RegisterXXX for it)

But I still think that my work will be useful for others...

So, script name is "evalscripts.js".
Before using you must delete first line (<script ... >) and last (</script>). I testing coloring on this forum :)
