Child Selection on Parent Selection in Tree Table

[vinayaknath_singh]

Hi,

I am using a tree table with multi-selection.

My requirement is: on click of parent checkbox, child's checkbox should get selected automatically.

Can it be configured in tree table or we need to do JavaScript coding?

Thanks,

Vinayak.

I was facing same issue. because I was using Treetable in a fragment. I have used these codes and it worked.

Controller:

in the top of the controller:

function addSelectedFlag(aNodes, bSelected) { jQuery.each(aNodes, function(iIndex, oNode) { oNode.selected = bSelected; if (oNode.categories) { addSelectedFlag(oNode.categories, bSelected); } }); }

onSelect: function(oEvent) { var aItems = oEvent.getParameter("listItems") || [], oModel = this.getView().getModel(); jQuery.each(aItems, function(iIndex, oItem) { var oNode = oItem.getBindingContext().getObject(), bSelected = oItem.getSelected(); if (oNode.categories) { addSelectedFlag(oNode.categories, bSelected); } }); oModel.refresh(); },

View:

<m:Tree id="TreeTableBasic" items="{path:'/questiontree/troubleshooting', parameters: {arrayNames:['categories']}}" mode="MultiSelect" selectionChange="onSelect" ariaLabelledBy="title" includeItemInSelection="true"> <m:StandardTreeItem title="{name} {code}" selected="{selected}"/>

</m:Tree>

I think you need to code

Try using addSelectionInterval or setSelectionInterval method of TreeTable, If you want to orverride previous selections use second option.

Check methods descriptions
