How to select checked treeview item?

[Ruth]

If I click on a checkbox, it does not select a treeview item. How to programmatically select it?

Hi Ruth,

Thank you for contacting us. You can use the Checked and Unchecked events of RadTreeView:

<telerik:RadTreeView IsTriStateMode="True" IsOptionElementsEnabled="True" ItemsOptionListType="CheckList"
        Checked="RadTreeView_Checked" SelectionMode="Multiple" Unchecked="RadTreeView_Unchecked">
    <telerik:RadTreeViewItem Header="Root">
        <telerik:RadTreeViewItem Header="Child #1" />
        <telerik:RadTreeViewItem Header="Child #2" />
        <telerik:RadTreeViewItem Header="Child #3" />
    </telerik:RadTreeViewItem>
</telerik:RadTreeView>

private void RadTreeView_Checked(object sender, Telerik.Windows.RadRoutedEventArgs e)
{
    RadTreeViewItem checkedItem = e.OriginalSource as RadTreeViewItem;
    if (checkedItem != null)
    {
        checkedItem.IsSelected = true;
    }
}

private void RadTreeView_Unchecked(object sender, Telerik.Windows.RadRoutedEventArgs e)
{
    RadTreeViewItem checkedItem = e.OriginalSource as RadTreeViewItem;
    if (checkedItem != null)
    {
        checkedItem.IsSelected = false;
    }
}

Give it a try and let me know if it works. I'd be glad to further assist you.
