How to use a custom property on a report?

[Jon]

Hi..
I added property to my report called   _total_cost

 

public partial class  Total_Tons : Telerik.Reporting.Report

 

{

 

    public decimal _Total_Cost { set; get; }


I have code that calculates the the total cost in the ctor of the Report

this.DataSource = _lstInvoices

 

 

var ct = _lstInvoices.Sum(c => c.cost);

 

_Total_Cost =

Convert.ToDecimal(ct);


How can I use this value in the TEXTBOX ?

When I set the text value to.....
Value =   "= (Sum(Fields.cost)/_Total_Cost)*100"

I get an error 

"_TOTAL_COST is NOT DEFINED IN THE CURRENT CONTEXT'


thanks in advance

Hi Jon,

You cannot use a custom property directly in a report expressions. You can however create a User Function
which works with your custom property and returns the desired result. More information is available in the latter article.
