I'm getting "Sys, WebForms.PageRequestManagerServerErrorException: an unknow error occured while processing the request on the server. the status code returned from the server was: 500".

I'm using a GridView and Button in an Update panel, and on click on the button i'm returning selected rows from the gridview which was throwing the above error in javascript popup. Specifically this error is coming only if I assign "DataKeysNames" property of the gird view. Otherwise, it is working fine.

Please help me how to resolve this error.

Thanks inadvance

Regards

Anand

Upps... It is not with the DatakeyNames property. I'm getting error when adding BoundFields to grid by hand (i.e. from code). It is working fine with AutogenerateColumns = True

Hi,

Did you ever get to the root of this issue? I'm currently on ajax beta 2 and the scenario is similar, an UpdatePanel with a GridView, I manually specify each column in the markup and use an ObjectDataSource binding through a home-cooked DAL.

One of the columns, which has an imagebutton that opens a window via javascript window.open raised this error once. I can't reproduce it consistently but it is a concern.

Any info on this would be appreciated,

Chris.-

</form>
</body>
</html>

This is my project...(I even dunno how to set the date on Calendar1 as TargetCotrolID rather than using an extra LinkButton, could any one help?)

I am getting the same error, but I've narrowed it down to the line of code that causes the error, so hopefully this might help. (I cannot send any code / sample project due to the sensitivity of our projects).

We use Telerik web controls a lot (great contorls!!!). We have a simple Treeview on the left with a bunch of fields on the right. in those fields I have 2 rad editors (WYSIWYG HTMl editors).

When I click something on the left treeview, it populates information into the fields on the right from the DataBase. WHen I click the first time, it loads everything fine. When I click again on the Treeview, it errors out.

editor.Html = objasdf.asdfText;

That line of code kills it. I'm not sure Why, but I know when I comment it out, it works fine...

So the error could be when you're updating a control that's "ajaxified" already and it messes it up... Not sure

I hvae about 10 UpdatePanels on my web form, not sure if having that many can cause this as well.

----------------

Edit: I'm looking at the code you provided and you have nested UpdatePanels... is that allowed? I'm not sure if that is what is causing the errors...

------------

Edit #2: Here is how the error is raised in my scenario:

Whenever I update a control with HTML text. ie. "<h1> HI </h1>" . I get an error when I update the rad:editor from telerik with '<h1> hi </h1>'. That is what causes this error for me.

Again I think it might be custom 3rd party controls mixing with beta asp.net ajax. (I'm using Beta 1 BTW).

I made some progress identifying the issue. In my case it was the misspelling of the UpdateMethod property of the ObjectDataSource attribute. I had renamed the method in my data class and forgot to update the html.

That being said, this was hard to pinpoint because there is no way to stop at an exception or anything, the problem I believe is that this exception happens internally to the object data source which has been called by the gridview and the exception details are not bubbled up, you just get the misleading 'WebForms.PageRequestManagerServerErrorException: Status code 500' error as the update panel is trying to refresh itself.

For anybody else who might run into this, I've verified that the cause could also be that you parameters (sql parameters) for either of the insert/update/delete actions are not in the proper order or the right types. They must match the signature of the data method that's supposed to be called.

Luis, if this is not clear enough, let me know and I'll put a self-contained sample together, although, at least on my case there is nothing to be fixed other than I would like the error that's raised by the updatepanel to include some of the inner exception details.

Thanks,

Chris.-

I have had the same error, certainly because I use FckEditor in an updatepanel,

I resolved it by adding ValidateRequest="false" in the tag <%@ Page ...%>
