Stored Procedure call: The expression contains object 'myobject' that is not defined in the current context

Hi,

I'm very new to telerik reporting. Please check my issue below.

I have created a telerik report using designer. This report calls stored procedure to retrieve the data and binds to chart.

I'm getting following error message when I generate the report via report viewer.

"The expression contains object 'dtScan' that is not defined in the current context".

I have already added all required report parameters (input parameters). Actually this 'dtScan' is not an input parameter. It is a one of the data table field and using inside my stored procedure. I'm sure that there is no issue on my stored procedure. It is working perfectly when I design the report (means that when I set stored procedure to report via design wizard).

As I mentioned, I'm getting this error message when I generate report via report viewer and as well as preview window (please see the attached images).

Please looking forward your help to solve this issue.

Thanks!

Binding Report List to ObjectDataSource List Property

I'm trying to figure out how to bind a List to a List<T> property of my main data source and I'm having trouble.

I have a report that binds like this:

And the Quote looks like this:

public class Quote
{

public int Id { get; set; }
public DateTime Created { get; set; }

...

public List<LineItem> LineItems { get; set; }

}

where LineItem is just a basic object like this:

public class LineItem

{

public int Id { get; set; }

...

}

The main report binding fields work great with [= Fields.Id]

However, I can't figure out how to bind the LineItem List to a List report object. In the designer it will only let me bind the datasource with the ObjectDataSource that is set to Quote. It won't let me choose the LineItem list. I feel like I'm missing something here.

What am I not doing right? I would rather keep it all in one report and not do a subreport if I don't have to.

Thanks!

public int Id { get; set; }

public class Quote
{

public int Id { get; set; }
public DateTime Created { get; set; }

...

public List<LineItem> LineItems { get; set; }

}

public class Quote
{

public int Id { get; set; }
public DateTime Created { get; set; }

...

public List<LineItem> LineItems { get; set; }

}

How to force Group to print on new page

I'm trying to get my report to force a new page once the group changes. I can't see anything in the properties so I'm thinking maybe there is a way to do it in code. Anyone know of a way to do this? Thanks.

Passing Drillthrough Parameter with Dynamic Data Binding

We are binding our reports through the code-behind. I need to create a drillthrough report. I have watched the video, and set up the Master report action correctly -- I selected the child report using the "Select Report Document" and I created the target report parameter. On the Child Report, I have created the parameter to match the one specified within the master.

However, on my child report, I cannot figure out how to access this parameter. It is not being passed into the constructor (get an error if I force the constructor to accept a parameter) and the "Load" and "Init" events of the child report do not fire. The value of the Report.Parameter I have defined is null.

How can I access this passed-in parameter value?
