Problem going from version Q3 2009 to Q1 SP1 2011

[Nikolay Paraskov]

Hello, 


I'm trying the transition from TelerikReporting Q3 2009 to Q1 SP1 2011 version. In my code I'm creating a Table Dynamically and Databinding it. 

Which results in the following exception:

[NullReferenceException: Object reference not set to an instance of an object.]
   Telerik.Reporting.Processing.Table.MeasureColumns(Graphics graphics) +299
   Telerik.Reporting.Processing.Table.Measure(MeasureDirection dir, Graphics graphics) +58

   System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +100
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +75
 

Any help would be Greatly Appreciated.


Thanks in advance.

Hello Nikolay,

Such an error can occur if you have a textbox which has zero set for Size which is no longer correct since Q2 2010 due to changes we introduced to the Table item. Changing the size to a smaller value would resolve the problem. Note that setting row/column groups to zero size sets them Visible=false, which is not supported. Due to the data driven nature of the CrossTab/Table, when you want to hide some data, you need to filter the CrossTab groups instead of hiding them.

All the best,
Steve
