Members

Name	Description
Default	For columns being filtered by their display text (see TreeListColumn.FilterMode), the Default option acts identically to the Like option. The Default option acts like the Equals option for the columns that have any of the following in-place editors or any of their descendants: CheckEdit, DateEdit, LookUpEditBase or ImageComboBoxEdit. For other columns, the Default option acts identically to the Like option.
Like	The Like comparison operator selects records whose values in the corresponding column start with the entered string. For the columns that use CheckEdit, DateEdit, LookUpEditBase or ImageComboBoxEdit in-place editors, the Equals operator is always used, unless these columns are filtered by display text (see TreeListColumn.FilterMode).
Equals	The Equals comparison operator selects records whose values in the corresponding column match the entered value.
Contains	The Contains operator selects records whose values in the corresponding column contain the entered string.
BeginsWith	Selects records that start with the entered string. Equal to the AutoFilterCondition.Like clause with the “%” wildcard after the searched string. For example, the [Name] BeginsWith ‘A’ and [Name] Like ‘A%’ filtering expressions are equal.
EndsWith	Selects records that end with the entered string. Equal to the AutoFilterCondition.Like clause with the “%” wildcard before the searched string. For example, the [Name] EndsWith ‘A’ and [Name] Like ‘%A’ filtering expressions are equal.
DoesNotContain	Selects records that do not equal the entered string. This clause acts as an opposite to the AutoFilterCondition.Equals clause.
DoesNotEqual	Selects records that do not equal the entered string. This clause acts as an opposite to the AutoFilterCondition.Equals clause.
Greater	Selects records that are greater than the entered value. For text records, “greater” values are those that would lie below the entered value in an alphabetically sorted list. For example, in a list with Latin characters, all letters from “N” to “Z” are greater than the letter “M”.
GreaterOrEqual	Selects records that are greater than the entered value or equal to it. For text records, “greater” values are those that would lie below the entered value in an alphabetically sorted list. For example, in a list with Latin characters, all letters from “M” to “Z” are greater or equal to the letter “M”.
Less	Selects records that are less than the entered value. For text records, “less” values are those that would lie above the entered value in an alphabetically sorted list. For example, in a list with Latin characters, all letters from “A” to “L” are less than the letter “M”.
LessOrEqual	Selects records that are less than the entered value or equal to it. For text records, “less” values are those that would lie above the entered value in an alphabetically sorted list. For example, in a list with Latin characters, all letters from “A” to “L” are less than the letter “M”.
NotLike	Selects records that do not match the entered string. Acts as an opposite to the AutoFilterCondition.Like clause. For example, from a list with month names the [Name] Like ‘J%y’ filter expression will return the “January” and “July” records. The [Name] Not Like ‘J%y’ expression will return the names of remaining ten months.

Remarks

The Automatic Filtering Row allows end-users to filter data on the fly. Typing text within the row’s cell automatically creates a filter condition against the corresponding column. The comparison operator used in this condition is determined by the column’s TreeListOptionsColumnFilter.AutoFilterCondition property of the AutoFilterCondition type. The values can be compared using the Equals or Like operators.
