Set Filter - API
This section describes how the Set Filter can be controlled programmatically using API calls.
Set Filter Model
Get and set the state of the Set Filter by getting and setting the model on the filter instance.
The filter model contains an array of string values where each item in the array corresponds to an element to be selected from the set.
Set Filter API
The Set Filter has the following API (in addition to the API common to all provided filters):
|Returns the full list of unique values used by the Set Filter.|
|Sets the text in the Mini Filter at the top of the filter (the 'quick search' in the popup).|
|Gets the Mini Filter text.|
|Refreshes the values shown in the filter from the original source. For example, if a callback was provided, the callback will be executed again and the filter will refresh using the values returned. See Refreshing Values.|
|Sets the values used in the Set Filter on the fly.|
|Resets the Set Filter to use values from the grid, rather than any values that have been provided directly.|
It is important to note that when updating the Set Filter through the API, it is up to the developer to call
filterInstance.applyModel() to apply the changes that have been made to the model and then
gridOptions.api.onFilterChanged() at the end of the interaction with the filter.
If no call is made to
filterInstance.applyModel() then the filter UI will show any changes, but
they won't be reflected in the filter model. This will appear as if the user never hit the Apply Button (regardless
of whether the Apply Button is active or not).
If no call to
gridOptions.api.onFilterChanged() is provided the grid will still show the data relevant
to the filter before it was updated through the API.
In the example below, you can see how the filter for the Athlete column is modified through the API and how at the
end of the interaction a call to
gridOptions.api.onFilterChanged() is performed.
