    Hi all
    Due to technical reason we have to fully postback our ASP.NET MVC view. This view contains a Kendo TreeView which will be loaded and bound in the view to the model as follow:
    ourModel is:
    It seems that there is no property 'selected' in this TreeViewItemModel class. So my question is: Is it possible to select a TreeView Node on server side? If not what would be a good solution to preserver selected Node during postback?

    Thanks for help

    Hello Adrian,

    Indeed, the Selected property is currently missing and we will include it for the next internal build. For now, in order to set the selected node on the server I can suggest to use the ItemAction callback:

    .ItemAction(item =>
        if (item.Id == SelectedID)
            item.Selected = true;
    or explicitly specify the binding:
    .BindTo(ourModel, mapping => mapping
        .For<TreeViewItemModel>(binding => binding
            .ItemDataBound((item, node) => {
                item.Selected = node.Id == SelectedID;
                item.Text = node.Text;
                item.Id = node.Id;
                //assign all used properties                       
            .Children(item => item.Items))
