Example 2. Highlighting even rows of the band

In this example we will show how to change the fill color of the "Data" band's even rows. We will be using:

• BeforePrint band event;
• reference to the Row# system variable from the script.

Create a simple report having the following appearance:

Create a BeforePrint event handler for the band:

private void Data1_BeforePrint(object sender, EventArgs e)
{
  if (((Int32)Report.GetVariableValue("Row#")) % 2 == 0)
    Data1.FillColor = Color.Gainsboro;
}

The Row# system variable returns the number of the row of the printed band. In order to insert into the script a reference to the variable, drag it from the "Data" window. During this, in the script a string will be inserted:

((Int32)Report.GetVariableValue("Row#"))

If we run the report, we will see that even rows will be highlighted in light-gray color:

The same effect can be achieved with the help of the EvenStyle property of the "Data" band. You can read more about this in the "Highlight odd/even data rows" section of the "Report creation" chapter.
