[Solved] Show counts of items under a node

[Gregor]

Is there a way to show the number of items in a parent node, as well as the number of child nodes under each sibling?

[Alex Gyoshev]

Hello Gregor,

You can use the treeview templates and get the items count through item.items.length:

#= item.text #
# if (item.items) { #
    (#= item.items.length #)
# } #

All the best,

#= item.text #
# if (item.items) { #
    (#= item.items.length #)
# } # 

 Does not return number of items.. It returns (0)

Hello Jose,

I am afraid that this approach has not been relevant for quite some time. You can calculate the children count in the dataBound event, as shown in this Dojo snippet.

Is there an updated version of this? These steps don't work in the current version.

I have created a new dojo sample that illustrates how the functionality can be achieved.

The example uses the dataBound event and checks the number of child nodes for each item. Then the count is shown as a badge element next to the parent title.

Give the sample a try and let me know how it works for you.
