what is the data type of your field you want to bind?

The data type is string. The field contains "false" or "true". And should be bound to the checkbox´ checked attribute which takes boolean.

Thanks!

Try This

Checked='<%#(Eval("Field").ToString() == "true" ? true : false) %>'

Thanks alot!
But it did not solve my problem.
With this solution, i can DISPLAY the correct data (if the box are checked or not). But when the user updates the data (changes the checked state), the ObjectDataSource´s UpdateMethod sees the field as null.
Is there a workaround on this? Smile | :)

"Sys.WebForms.PageRequestManagerParserErrorException" while using AJAX

Hi,

I have an issue relating to AJAX Confused | :confused:

. I have an AJAX enabled webform where I have various controls and one button among them requires to open a new page (.asp) which should have all the controls of the source page.

I have achived this functionality. but after a new page opens in new window, my source window started giving error on any control change. THe exact Error Message is:

Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled

One scenario I can understand is, I have used

window.document.formrs.action = "Test.aspx"; // New Page in New Window
            window.document.formrs.target = "_blank";
            window.document.formrs.submit();

when going to new page, and when returning, it is set back to

window.document.formrs.action = "RS_Test.aspx"; // Source Page
           window.document.formrs.target = "_self";

Because of this, my viewstate might be changing thus Response is modified... D'Oh! | :doh:

I need to completely eliminate chnaging Form.action property for some reasons. Please help..... Sigh | :sigh:

Thank You.

Anand Desai

The error occurred not because there some problem with your code.

It is because .NET Framework does not handle the request validation and the exception is thrown.

For more information refer following links, it will solve your problem surely.

Thanks Jinal,

The thing is, I have resolved the problem by overriding "Render" method and the error disppeared. Thumbs Up | :thumbsup:

Thanks a lot for all inputs. Rose | [Rose]

One another issue is I have an classic ASP Page I am traversing from AJAX Enabled .aspx page. And I require all the controls (basically whole page) in that .asp page. . Confused | :confused:

In this scenario,

1) "PostBackUrl" is not applicable.
2) "Session" is not useful also because I will not get ASP.NET session in classic ASP.
3) Talking about Querystring and Cookie is pointless.

Can you suggest something to achive this??? D'Oh! | :doh:

Thank You.

Then there is only one thing that will help you to do so is Javascript.

There is around two ways to do that.

1. You can use hidden fields to store the values and then access it on second page.

2. Second way is shown in below link.

http://www.boutell.com/newfaq/creating/scriptpass.html[^]

However you can also go for following links, may be help you more.

is there a way to register in GAC??

HI,

I bought a ecommercemax_upsrates.dll to check ups rate from our website.
it worked for a month and now I am getting this error message.

"could not load file or assemble 'ecommercemax_upsrates, Version=1.0.3480.35489, Culture=en, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified. "

I have a feeling that if I can register this dll to assembly (c:/windows/assembly), it might work fine.
I am just referencing this dll and send parameters to check up the rate.

when I try to register in GAC, an errors message pops up says that I need strong name.
so I made snk file, but still cannot register in GAC.

any ideas???

By looking at the error message it seems that some dependency dll
that is required to be registered in GAC may be deleted or
unregistered from GAC.

For GAC Commands and other details you can check following links.

http://msdn.microsoft.com/en-us/library/ex0ss12c%28VS.80%29.aspx[^]

You can confirm whether your assembly is really added to GAC or not by traversing following path
which opens GAC Space where all the assemblies (added to GAC) reside.

%WINDIR%\assembly

You can also add your assembly to GAC by directly drag your assembly and drop it in GAC Space.

Hope this will help!

This mostly depends on your browser. Some browsers will start completely separate instances which know nothing about each other, others will share their session freely. (I haven't seen any modern browsers which do not share their credential data). Can't you login twice?

Response.ContentType = "Music/mp3";
Response.AppendHeader("Content-Disposition", "attachment; filename=music");
Response.TransmitFile(Server.MapPath(sPath));
Response.End();

Also you can use WriteFile method insted of TransmitFile method.

Hope this may help u.... Smile | :)
