I create a repoort using "Syncfusion Report Designer", I  add % column and I use this expression on it:
I get an error on Report Designer and on the browser when I run my project, but when I open the report with "SQL Report Builder, everything works fine (take a look at the screenshot below).
What is the problem?

Hi Anis, 
Thanks for contacting Syncfusion support. 
We were unable to reproduce the mentioned the same null exception issue at our end. But, we have tested the shared reportitem expression and it’s rendered the same values in all the row cells (this is the know error) in Tablix report items as shown in below screenshot. So can you please share the issue reproducible RDL file without confidential information to validate the mentioned null exception issue at our end.  

ReportViewer O/P: 
For your reference, we have prepared a sample and it can be downloaded from,

I reproduce the issue in the sample below (+RDL file).
About your RDL file, I get the same error (render the same values in all the row cells) but instead it works well in SQL Report Builder.
Another problem about the percentages, I have diagrams (Pie) showing the percentage of each part in SQL Report Builder, but in the browser (ReportViewer), it just show me the total number without percentage. How to fix this too?

Hi Anis, 

Currently, we don’t have support for using aggregate function for reportitems expression in ReportViewer and we have an issue while providing data label format in chart report item at our end. We have logged a feature and defect report on this respectively. So a support incident to track the status of this feature and issue has been created under your account. Please log on to our support website to check for further updates.
