Access Report items which are in header from a table in detail section

[Pavan]

I have a report with header and multiple sub sections in details section.
For each subsection we have placed table and assigned corresponding datasource.
In header i have a textbox which contains patient related data.
Eg:textbox1 -->Expression--> [=Fields.NameField]


Now i need to display a caluculate field in table1 column based on the value of the textbox in header section.

eg:
Table1
----------------
textbox2-->Expression-> =FormatName() (UserDefined function)

In code behind file .cs

public static string FormatName()
{
return textbox1.Value+ "Busineess Logic";
}
But i am not able to access textbox1 here in this method as the method is declared as static.

How to achieve this in telerik ???

Hello Pavan,

When using Custom Functions you can also pass expressions to them. For e.g.  =FormatName(Fields.NameField) will pass the already evaluated expression to the user function. If it is something simple like string concatenation you don't even need functions - you can do it in the expression for e.g. = Fields.Name + " " + Fields.Age will concatenate the two strings with space between them. 
You should also keep in mind that if you assign DataSource to the Report, the Fields cannot be used directly in the Report Header/Footer - they need to be used with Aggregates. If you explain in more detail what exactly is your scenario and what do you need to achieve, we might be able to give you more concrete solution.
