Show All
Hide AllIn a section layout, you can use conditions in the Format event to control the display of report's detail section at runtime.
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.

Note: These steps use the Products table from the NWind database. By default, in ActiveReports, the NWind.mdb file is located in the [User Documents folder]\ComponentOne Samples\ActiveReports 9\Data\NWind.mdb. |
- 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.

To write the code in Visual Basic.NET
Visual Basic.NET code. Paste INSIDE the Detail_Format event. Copy CodeIf 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 IfTo write the code in C#
C# code. Paste INSIDE the detail_Format event. Copy Codeif (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;
