I'm using Telerik reports in an asp.net MVC project.

A report I'm trying to generate is failing before it gets started, in the [HttpPost] ActionResult in the Controller; I reckon because "if 
(ModelState.IsValid)" is returning false.

I didn't know what IsValid was; on investigation, I see that it is defined in System.Web.Mvc.ModelStateDictionary

So what are the causes of a ModelStateDictionary being invalid? What should I examine or verify?

Hi All - Im looking at the KB article: The expression contains undefined function call MyUserFunction() error

http://www.telerik.com/support/kb/reporting/designing-reports/the-expression-contains-undefined-function-call-myuserfunction-error.aspx

excerpt ...

PROBLEM
The following error is thrown when running the report: #ERROR# The expression contains undefined function call MyUserFunction()

SOLUTION

This error can occur in any of these three cases:

1. The class library has not been rebuilt and thus the function does not yet exist.
2. Using the function with wrong number/type of parameters. The passed fields must match the function signature you've defined originally.
3. A field specified as function argument is null. Make sure that such cases are handled in the user function.

In my case I think its #3. 

I have a report that uses date ranges to filter data.  if a user select a date range that results in zero records, I get the undefined user function error.  I assume because of the nulls.

#3 above mentions "Make sure that such cases are handled in the user function"  by this assume Telerik means use something to the effect of  ..

If (MyParam==null) {return 0;)

I tried this and still get the error, so I must be doing something wrong.

Could someone please test this and report back?

generate a report with a simple UDF.  pass a null dataset to the report.  Do you get the same error? 

I got the following error on report load, what should I do?

All of my reports are currently in Active Reports 6.0 and I'd like to convert them to Telerik but when I get to that part of the wizard active reports doesn't even show up as an option.  I've tried the redirect in the devenv.exe.config but that didn't help.  From what I've been able to gather from a couple of other posts there is no converter for AR 6 but I thought I should at least have it as an option, even if it doesn't really work.  Has anyone else run into this?

Hi,

I would like to know how to access the Fields.Item equivalent for a collection of complex objects. Unless I am overlooking something, the documentation for expressions is woefully inadequate. Where does the documentation mention the use of Fields.Item and other available api? The only time I have seen any mention of the use of these api is in replies to forum posts and these are few indeed. Most of the replies that mention it are from Steve (many thanks for those).

In any case, what I am trying to do is pass the current list item data context to a method on the report data source object. The data source object exposes a list of complex objects that are used as the data source for a list in the report. The method call occurs when a table grouping expression is evaluated.

Expression example:

"=ReportItem.Report.DataSource.MyMethod(Fields.Item)"

If I can access the "Fields.Item" object everything works but of course it only works for objects such as strings.

I am using the latest version of the telerik controls (Q1 2013 build 7.0.13.228).

Thanks,
Tom

I'm creating a simple label report. The label is preprinted with the logo, address and headers and I'm just filling in the data.

What I would like to do is create the report as it will print, so that when they preview it ,it'll look like it will on the preprinted form (with the logo, address and headers), but don't want the headers and such to print when they actually print.

Is there a way to do this?
