Gantt Filtering Overview
The Gantt Tree component offers built-in support for filtering.
Basics
To enable filtering, set the grid's FilterMode property to one of the following values:
-
Telerik.Blazor.GanttFilterMode.FilterRow- a row of filter options is rendered below the column headers -
Telerik.Blazor.GanttFilterMode.FilterMenu- the column headers render a button that shows a popup with filtering options
The behavior of the filter input and the available filter operators will depend on the column data type. For example, a boolean field will only have the options "is true" and "is false" and will not have operators like "contains" or "greater than".
You can filter more than one column at a time, and all filter rules will be applied together with an AND logic.
Filter Descriptors
You can get the applied filtering criteria for each filtered field. Use the Gantt state to obtain the user input, the filter operator and other filtering properties. Find out how in the Data Operation Descriptors article.
