Expand / collapse node clear the checkbox indeterminate state

[Kay]

Hi,

We have checkbox (<input type='checkbox' ...>) in each row of TreeList where we will set it as indeterminate state by below code:

     checkboxElement.prop('indeterminate', true);

It works fine until I expand or collapse a node. All those 'indeterminate' checkbox are cleared.

Please kindly advise any way to prevent such clearing.

Thanks!

Kelvin

Hello Kelvin,

I made an example of the Kendo UI TreeList with indeterminate (tri-state) checkboxes:

http://dojo.telerik.com/IbEMu

Also, the checkboxes in the TreeList should be implemented using the columns.template configuration:

http://docs.telerik.com/kendo-ui/api/javascript/ui/treelist#configuration-columns.template

If this is not helpful in your scenario, please send a runnable example that reproduces the issue, so we can investigate in further.
