问题
I am trying to have my own custom filter on ag-grid angular.
Apart from Apply button, I also want to have other buttons for the filter. i.e. if I can explain this in some sort of UI,
|--Custom Filter-------------------.
| Filter Text: _____________ |
| Apply | Clear | Clear All|
|_______________________|
By using default filter component of ag-grid, I know that I can have two buttons I need if I provide filterParams in ColDef.
filterParams: {
applyButton: true,
clearButton: true
}
But what about the other custom (Clear All) button? Is there any way I can achieve it?
回答1:
Achieved it after few hours of search and trial-error.
Have a look at the example given here: ag-Grid Angular Custom Filter Component
Have a look at the PartialMatchFilterComponent and its code.
After some code updates for template and component, we can achieve it.
Update the template:
<button (click)="apply()">Apply</button>
<button (click)="clear()">Clear</button>
<!-- any other buttons you want to keep -->
Little update in the component code: Just need to call this.params.filterChangedCallback() on Apply button click.
apply(): void {
this.params.filterChangedCallback();
}
clear(): void {
this.text = '';
this.params.filterChangedCallback();
}
onChange(newValue): void {
if (this.text !== newValue) {
this.text = newValue;
// this.params.filterChangedCallback(); - remove
}
}
