Pass context to Click Handler

[Joel]

How can I pass the context of a TreeView's ItemTemplate to a click handler?  This is what I have:

<TelerikTreeView Data="@TreeData">
    <TreeViewBindings>
        <TreeViewBinding IdField="Id"
                         TextField="Text">
            <ItemTemplate>
                @{
                    <TelerikButton OnClick="@OnClickHandler">@((context as TreeItem).Text)</TelerikButton>
                }
            </ItemTemplate>
        </TreeViewBinding>
    </TreeViewBindings>
</TelerikTreeView>

@code {

    public class TreeItem
    {
        public string Id { get; set; } = $"{Guid.NewGuid()}";
        public string Text { get; set; }
        public ObservableCollection<TreeItem> Items { get; set; } = new ObservableCollection<TreeItem>();
        public bool Expanded { get; set; }
        public bool HasChildren { get; set; }
        public bool Selected { get; set; }
    }

    private void OnClickHandler(TreeItem context)
    {

    }

Hello Joel,

In the ItemTemplate you can directly pass the context as delegate. I have created a code snippet based on the demo you provided:

@using System.Collections.ObjectModel

<TelerikTreeView Data="@TreeData">
    <TreeViewBindings>
        <TreeViewBinding IdField="Id"
                         TextField="Text">
            <ItemTemplate>
                @{
                    var myContext = context as TreeItem;
                    <TelerikButton OnClick="@(() => OnClickHandler(myContext))">@myContext.Text</TelerikButton>
                }
            </ItemTemplate>
        </TreeViewBinding>
    </TreeViewBindings>
</TelerikTreeView>

@code {
    public ObservableCollection<TreeItem> TreeData { get; set; }
    public class TreeItem
    {
        public string Id { get; set; } = $"{Guid.NewGuid()}";
        public string Text { get; set; }
        public ObservableCollection<TreeItem> Items { get; set; } = new ObservableCollection<TreeItem>();
        public bool Expanded { get; set; }
        public bool HasChildren { get; set; }
        public bool Selected { get; set; }
    }

    private void OnClickHandler(TreeItem currentContext)
    {

    }

}
