use Ajax: Problem in using Atlas with UserControl

Hi,

I have a UserControl named as cppCombo.ascx , that is used inside another combo named as welcome.ascx, and this welcome.ascx is again used in Loginmaster.ascx and finally used in a aspx page.

Now the problem is that at the aspx page i am unable to know the EventName .

If you have any other better option then please post that.

Thanks & regards

Try to use the triggers of a asp:UpdatePanel to trigger the events of a user control as the following codes.
<asp:UpdatePanel ID="upnlUserControl" runat="server">
????<ContentTemplate>
?????????<uc1:WebUserControl0 ID="WebUserControl0_1" runat="server" />
????</ContentTemplate>
????<Triggers>
?????????<asp:PostBackTrigger ControlID="WebUserControl0_1" />
????</Triggers>
</asp:UpdatePanel>
Wish this could help you.

I used the same but it shows an error.

Unknown server tag 'asp:PostBackTrigger'.

How should i solve this .

It is impossible that says "Unknown server tag 'asp:PostBackTrigger'" in Ajax Beta 2 or Ajax RC 1.0.Do you download the latest Ajax package and install it in your PC?If not,try to download it from this website - http://ajax.asp.net/default.aspx?tabid=47&subtabid=471 and install it in your PC.It should work fine.If not,can you post some codes here? I'd like to test it.

Actually i was using ATLAS and their was no such tag but now i have downloaded AJAX from the site you provided thanks for this.

Now the problem is that i have to implement AJAX in an already built website. With atlas i just took the ATLAS.dll and put that the bin folder of

my wesite and using its fascility . But now with AJAX i am confused , How should i embed it in the website.

Thanks and Regards

Don't worry about it.If create an old website with Atlas, you can take a look at this materials to upgrade it to the new Ajax RC 1 - http://ajax.asp.net/

Hi, I did the same as it was directed in the URL but now i have received another problem . now it gives an error that,

Sys.WebForms.PageRequestmanagerParserErrorException: The message Received from the server could not be parsed.

Common cause for the error are when the responseis modified by the calls to Response.Write(),response

filters, HttpModules, or server trace is enabled.

Details: Error parsing near '<script language='ja'.

Try to send your ajax website to my email box: v-jicwan@.microsoft.com? I'd like to test it.

Hi, Sorry i cant send you the project as it is not my personal. One reason that could behind this error may be the use of Response.Write

in the project , so now i am trying to replace it some how, soon i will tell you about the status .

Thanks & Regards

Hi, After replacing the Response.Write() now its not showing that error but Show an error from Java Script

Unknown Runtime Error.

Thanks & Regards

Shrikant

You can not use Response.Write method in behind code if you develop a web application based on Ajax framework. Can you post a simple web page with "javascript Unknown Runtime Error"? There are many reasons which can lead to javascript error. It is difficult to fix what causes it.

Hi, At present i am even confused whether i will be able to convert project from ASP.Net 2.0 to AJAX

The code gives error at this line.

updatePanelElement.innerHTML = rendering

Below is the value contained in updatePanelElement.innerHTML

Any other option that can help you to help me, please suggest..

I recommend you to remove the updatepanels, and validate your page. The above innerHTML value is definitely not a valid HTML content (for example multiple "Table1" values for id, using deprecated attributes etc.). When your page is validated againts some doctype (HTML 4.0 or XHTML 1.0) try again the updatepanel. Maybe this helps.

sorry, I am unable to get this.

How can i replace asp:UpdatePanel because without this how i will be able to update the page asyn.

Please make it more with some example ,if possible

I recommend to remove the updatepanels only because it help to validate your page. "Simply" comment out the updatepanel controls in the aspx file, and also comment out any updatepanel's related code in the code behind file. Then your page should work in the normal "old" way. Play with the page (try pushing your buttons etc.), and validateeachtime. Probably you will get some validation errors.

The easiest way (for me) to validate my pages in the browser (not in visual studio ide!), using firefox with the "web developer" add-in, there is also a similar add-in for ie. Or you can go to http://validator.w3.org/ directly.

At least incorrectly nested elements (if you have this error), and double ids (I think you have this error) should be corrected some way.

After you corrected the errors, "put back" the updatepanel and try again.
