I posted a couple of weeks ago about a "No Parameterless constructor" error I was getting:

I was referred to a thread:

On searching, I found a couple more:

The core of the problem is that when sessionState mode='StateServer' or mode='SqlServer' or mode='Custom', the Telerik reporting engine serializes the report, and then deserializes it using the derived class's parameterless constructor.

Now for us, using mode='inProc' is not an option.  I've got no great objection to passing the parameters to the derived report class in some other way.  But I'm at a loss as to what other way we can use.

We have a button click event on the page.  In it, we construct an instance of the derived report class, passing parameters to the constructor, and assign that object to ReportViewer.Report.  It does it's business, and the next time I'm in my own code is in the parameterless constructor of the derived report class.  But how do I access the parameters I used when I called the other constructor? 

I can't save them in member variables, because they aren't being saved and restored during serialization.

I'm not in a Page, so I have no access to Session.  (I thought for a moment that I might be able to access the page, through Report.Container, but it's null.)

So next, I thought that adding them to Report.ReportParameters.  But they're not being restored, either.

So where do I store them, so that I can restore them at the appropriate time?

I have a report that has picture boxes. If the path specified doesn't exist, the picture box renders as a huge error message that pushes other information off the report and causes blank pages to render. I would like the picture box to render either blank or stay within its defined size(not get unexpectedly large to display the error). I cannot assume that all pictures needed exist, but the picture information is not that critical. However the information the picture box error obscures is critcal.

Is there any way around this?

I have a stored procedure which gives me two different tables. One having the details of the loans and the other having calculated averages of the numbers of these loans. I have two sections of the report which are to be binded respectively with these two tables.
My problem is how can I handle a dataset with the procedure giving me two result sets?

Any help would be appreciated. Thanks

I've following xml file. Each room is a position on a invoice and each room may include multiple optional packages (sub positions). I know I can use the xml to create a dataset and bind it to the control, but how can I define which part of the data to use for the different sections and textboxes? Is there an expression to define table and column or binding a table to a subreport?

Hi,

Hi,

I've tried Reporting Q1 09 SP1. It seems something's wrong with Docking function in the below scenario.

- I've created a report, and added 2 groups to my report (groupHeaderSection1/groupFooterSection1 & groupHeaderSection2/groupFooterSection2).
- Drag & drop "TextBox" from ToolBox to group1, change its "Docking" property to "Left". It's working over here.
- But, when I drag & drop textbox from ToolBox or copy textbox from group1 to group2, Docking property over here seems not working.

Is it a bug or do I miss something???

Thanks,
Sandy

Hi,

I am trying to make conditional formatting GroupFooterSection2(GroupFooterSection) but i could not able to do. I am getting errors,  "An error has occured while processing TextBox 'TextBox12': The expression contains object 'Textbox12' that is not defined in the current context".

I am generating the report through programatically,  the values are displaying on the report. I place a textbox in the group footer section2 and try to sum of the columns and textbox value is =sum(Fields.M1).

The total sum value is displaying but when i trying to do conditional formatting i am getting an error. 

I just want to change the color of the sum textbox if it greater than 120.

Please tell me how to overcome with this problem.

Thanks.
