Hi

Is it possible to configure the Treeview checkboxes so that when a node's children are all deselected, the node is not deselected also? I need the CheckChildren functionality turned on so that children are automatically selected when their parent is. But I don't want the parent removed from the selection when its children are unchecked.

To illustrate I have set up a jsbin . I'd like to be able to select nodes a, b1 and b2. However b2 only shows checked when any of c1, c2 and c3 are checked. I can use CheckChildren(false) to allow selection of b1 and b2 individually, but I have much more data than this example so manually checking all the nodes would become too much for the user.

Here is how I am currently placing the treeview on the page (Model.Items is a list of TreeViewItemModel instances):

@Html.Kendo().TreeView().Name("treeview").BindTo(Model.Items).ExpandAll(true).Checkboxes(c => c
        .Enabled(true)        
        .CheckChildren(true)
        )

Any thoughts?

Hello Bill,

I am afraid this is not supported. If you do not want the children to be checked/unchecked automatically you have to disable the CheckChildren option. Since you cannot disable only one of the options you can disable CheckChildren and implement the checking logic manually.

Hi Estefania,

In order to achieve the desired behavior, I would recommend using the "checkChildren" property of the TreeView.

By setting it to false, the parent will not be deselected when all the children are deselected.

Here is an example:

I hope this information helps.

Kind Regards,
