Glossary Item Box

Gets or sets which column header row displays the row filter indicator when there are multiple column header rows.

Syntax

Visual Basic (Declaration) 
Public Property AutoFilterIndex As Integer
Visual Basic (Usage)Copy Code
Dim instance As ColumnHeader
Dim value As Integer
 
instance.AutoFilterIndex = value
 
value = instance.AutoFilterIndex
C# 
public int AutoFilterIndex {get; set;}

Property Value

Integer index of the row

Remarks

If your header has multiple column header rows, you can specify which row displays the filtering indicator by setting this property. To specify the index, set the property to a value between 0 and n-1, where 0 is the top row and n is the number of header rows. Any value above n-1 simply puts the filtering indicator in the bottom row.

If you set this property to specify a row to display the filtering indicator, for example, header row 3, and then later change the number of column header rows to be less than 3, the filtering indicator is displayed in the bottom row, as if the RowCount property is set to -1. However, if you then change the number of header rows to 3 or greater, the filtering indicator is again displayed in header row 3. Use the RowCount property to specify how many column header rows the component displays.

This property does not have an effect unless the Visible property (or the SheetView.ColumnHeaderVisible property) is set to true and the column header rows are not hidden.

Example

This example designates the row in the column headers in which to display the filter icon.
