In ponent of office 365 fabric ReactJs exists such ponent. It has _getSelectionDetails() method which counts selected items from list I want to make method which will reset it and will deselect items in list. For example we have button and when we press it, we reset all the items in the list, which we marked before. I tried to do :

_resetSelectedItems() :{
 this.setState ({ selectionDetails: 0 }) 
}

After I call it, it sets new state and sets 0, but items which were selected before remain selected, diselecting doesn't happen. How I can deselect items?

this.setState() performs a shallow merge of this.state into the new state, e.g. if this.state have selectionDetails and many more objects. this.setState ({ selectionDetails: 0 }) will update only selectionDetails other will remain unchange. You have to cleanup other objects manually.

ref : this.setState

Update :

finally i got it.... this._selection.setAllSelected(false) will work.

check out my github project or check online.
