Customizable reports are a variation on Reports Loaded at Run Time. This scenario consists of loading the basic report definitions from a file, then writing code to customize the reports according to user selections.

For example, the following code changes the font used in the Detail section:

To write code in Visual Basic

Imports C1.C1Report
     
Dim s As Section = c1r.Sections(SectionTypeEnum.Detail)        
Dim f As Field        
For Each f In s.Fields        
  f.Font.Name = "Arial Narrow"        
Next

To write code in C#

using C1.C1Report;

Section s = c1r.Sections[SectionTypeEnum.Detail];        
foreach (Field f in s.Fields)        
  f.Font.Name = "Arial Narrow";

The following code toggles the display of a group by turning its Sort property on or off and setting the Visible property of the Group's Header and Footer sections:

To write code in Visual Basic

Dim bShowGroup As Boolean        
bShowGroup = True        
With c1r.Groups(0)        
  If bShowGroup Then        
    .SectionHeader.Visible = True        
    .SectionFooter.Visible = True        
    .Sort = SortEnum.Ascending        
  Else        
    .SectionHeader.Visible = False        
    .SectionFooter.Visible = False        
    .Sort = SortEnum.NoSort        
    End If        
End With

To write code in C#

bool bShowGroup;        
bShowGroup = true;        
  if (bShowGroup)         
  {        
    c1r.Groups[0].SectionHeader.Visible = true;        
    c1r.Groups[0].SectionFooter.Visible = true;        
    c1r.Groups[0].Sort = SortEnum.Ascending;        
  }         
  else         
  {        
    c1r.Groups[0].SectionHeader.Visible = false;        
    c1r.Groups[0].SectionFooter.Visible = false;        
    c1r.Groups[0].Sort = SortEnum.NoSort;        
  }

These samples illustrate just a few ways that you can customize reports. There are infinite possibilities, because the object model offers access to every aspect of the report. (In fact, you can create whole reports entirely with code).
