I have same problem. I didn't figured out its origin yet, but I suppose it comes from data source binding. When you create new instance on report it creates default controls in InitializeComponent() method (for example, List with 0 rows or TextBox without text). And when you bind data source (for example, List with 3 items) it refer to List (Telerik Reporting control) and try to bind collection with 3 items to control with 0 rows. So in this case you had OutOfRangeException. Something like that, I guess.

UPD: actually, I had resolved my problem yesterday. It was all because I try to bind empty collection as control's data source. I just added default object (with empty properties) to my collection if it contains no elements before binding.

We have been experiencing a very similar issue intermittently. Clearing out the Telerik state database tables seems to resolve it sometimes for us. You can flip @Condition to 1 in the script below to execute the delete.

DECLARE @Condition AS BIT = 0;
IF @Condition = 1
BEGIN
    DELETE dbo.tr_AppLock;
    DELETE dbo.tr_Object;
    DELETE dbo.tr_Set;
    DELETE dbo.tr_String;
END;

SELECT *
FROM dbo.tr_AppLock AS tal;

SELECT *
FROM dbo.tr_Object AS tob;

SELECT *
FROM dbo.tr_Set AS ts;

SELECT *
FROM dbo.tr_String AS ts;

Check that you can preview the report in the Telerik Report Designer.

I was seeing the same error when running code:

System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

In the report designer I had the error:

Missing or invalid parameter value. Please input valid data for all parameters

I corrected the Report Designer error (by adding a default parameter value, see screenshot below) and made no other 'code' changes, this resolved both issues.

Interestingly if I remove the default value the Report Designer error returns but running the report in code remains OK (possibly the report is cached somewhere in a valid state?)
