Filtering

Filtering allows you to view specific or related records based on filter criteria. To enable filtering in the TreeGrid, set the allowFiltering to true. Filtering options can be configured through filterSettings.

To use filter, inject the Filter module in the treegrid.

Filter Hierarchy Modes

TreeGrid provides support for a set of filtering modes with filterSettings.filterHierarchyMode property. The below are the type of filter mode available in TreeGrid.

  • Parent : This is the default filter hierarchy mode in TreeGrid. The filtered records are displayed with its parent records, if the filtered records not have any parent record then the filtered records only displayed.

  • Child : The filtered records are displayed with its child record, if the filtered records not have any child record then the filtered records only displayed.

  • Both : The filtered records are displayed with its both parent and child record, if the filtered records not have any parent and child record then the filtered records only displayed.

  • None : The filtered records are only displayed.

Filter operators

The filter operator for a column can be defined in the filterSettings.columns.operator property.

The available operators and its supported data types are:

Operator  Description  Supported Types
startswith  Checks whether the value begins with the specified value.  String
endswith  Checks whether the value ends with the specified value.  String
contains  Checks whether the value contains the specified value.  String
equal  Checks whether the value is equal to the specified value.  String | Number | Boolean | Date
notequal  Checks for values not equal to the specified value.  String | Number | Boolean | Date
greaterthan  Checks whether the value is greater than the specified value.  Number | Date
greaterthanorequal Checks whether a value is greater than or equal to the specified value.  Number | Date
lessthan  Checks whether the value is less than the specified value.  Number | Date
lessthanorequal  Checks whether the value is less than or equal to the specified value.  Number | Date

By default, the filterSettings.columns.operator value is equal.

Filter bar

By setting the allowFiltering to true, the filter bar row will render next to the header, which allows you to filter data. You can filter the records with different expressions depending upon the column type.

Filter bar expressions:

You can enter the following filter expressions (operators) manually in the filter bar.

Expression  Example  Description  Column Type
=  =value  equal  Number
!=  !=value  notequal  Number
>  >value  greaterthan  Number
<  <value  lessthan  Number
>=  >=value  greaterthanorequal  Number
<= <=value lessthanorequal  Number
*  *value  startswith  String
%  %value  endswith  String
N/A  N/A  Equal operator will always be used for date filter.  Date
N/A  N/A  Equal operator will always be used for Boolean filter.  Boolean

Filter bar template with custom component

The filterBarTemplate is used to add custom components to a particular column, and does the following functions:

  • create: Creates custom components.
  • write: Wires events for custom components.

In the following sample, the dropdown is used as a custom component in the Duration column.

Custom component in filter menu

The column.filter.ui is used to add custom filter components to a particular column. To implement custom filter ui, define the following functions:

  • create: Creates custom component.
  • write: Wire events for custom component.
  • read: Read the filter value from custom component.

In the following sample, dropdown is used as custom component in the duration column.

You can use both Menu and Excel filter in a same TreeGrid. To do so, set the column.filter.type as Menu or Excel.

In the following sample menu filter is enabled by default and excel filter is enabled for the Task Name column using the column.filter.type.
