In a section layout, you can use conditions in the Format event to control the display of report's detail section at run time.

These steps assume that you have already added a Section Report (code-based) template in a Visual Studio project and connected it to a data source. See Adding an ActiveReport to a Project and Bind Reports to a Data Source for further information.

1. From the Report Explorer, drag and drop the following fields onto the detail section of the report and set their properties in the Properties Window.
   

   Field Name	Properties
   ProductName	Location: 0, 0.104 in Size: 2.667, 0.2 in
   Discontinued	Location: 2.667, 0.104 in Size: 2.021, 0.2 in
   ReorderLevel	Location: 4.688, 0.104 in Size: 1.812, 0.2 in

   
   
2. Double-click the detail section of the report to create an event-handling method for the Format event.
3. Add the following code to the handler to hide the details of a product which is discontinued.

   To write the code in Visual Basic.NET

   Visual Basic.NET code. Paste INSIDE the Detail_Format event.	Copy Code
   If Me.txtReorderLevel1.Value = 0 And Me.txtDiscontinued1.Value = False Then 　　　Me.Detail1.Visible = True 　　　Me.txtReorderLevel1.Text = "Need to Reorder" 　　　Me.txtReorderLevel1.ForeColor = System.Drawing.Color.DarkRed Else 　　　Me.Detail1.Visible = False End If

   To write the code in C#

   C# code. Paste INSIDE the detail_Format event.	Copy Code
   if (int.Parse(txtReorderLevel1.Value.ToString()) == 0 && txtDiscontinued1.Text == "False") { this.detail1.Visible = true; this.txtReorderLevel1.Text = "Need to Reorder"; this.txtReorderLevel1.ForeColor = System.Drawing.Color.DarkRed; } else { this.detail1.Visible = false; }

4. In Form1 of the Visual Studio project, add a Viewer control and load the report you created above in it. See Windows Forms Viewer for further details.
5. Press F5 to debug and see a report with discontinued products hidden from view.
