Hi,
I have a scenario in which i want to make ‘ALL’ selected in a dropdown cell.
Example -
in my first row, for Subsubjects column i have only one value in the collection which is checked but it doesn’t show ‘ALL’ value in UI.
https://stackblitz.com/edit/angular-e3228b?file=src/app/app.component.ts
For this i’ve added the below code -
if (col.binding === 'subjects') {
checkedItemsChanged: s => {
s.headerFormat =
s.checkedItems.length !== s.collectionView.sourceCollection.length
? s.checkedItems.toString()
: 'ALL';
item.subjects = s.checkedItems;
const subjectColIndex = grid.columns.getColumn('Subsubjects').index;
const rng = new wjcGrid.CellRange(rowIndex, subjectColIndex);
// console.log('The get length', this.getSubSubjects(item).length);
[b] if (
item.subjects.length > 1 ||
this.getSubSubjects(item).length === 1
) {
item.Subsubjects = this.getSubSubjects(item);
} else {
item.Subsubjects = [];
}[/b]
grid.refreshRange(rng);
}
// selectedIndexChanged: s => {
// grid.collectionView.refresh();
// }
});
e.cell.innerHTML = '';
e.cell.appendChild(host);
} else if (col.binding === 'Subsubjects') {
let multiSel = new wjcInput.MultiSelect(host, {
[b] checkedItems:
item.subjects.length > 1
? this.getSubSubjects(item)
: item.Subsubjects,
headerFormat:
item.Subsubjects.length < this.getSubSubjects(item).length
? item.subjects.length > 1
? 'ALL'
: item.Subsubjects.join(', ')
: 'ALL',
[/b]
checkedItemsChanged: s => {
s.headerFormat =
s.checkedItems.length !== s.collectionView.sourceCollection.length
? s.checkedItems.toString()
: 'ALL';
item.Subsubjects = s.checkedItems;
}
});
e.cell.innerHTML = '';
e.cell.appendChild(host);
}
Please provide solution.
Thank you.
