### Bug report
The ExpandAll() option does not expand or collapse the TreeView nodes.
### Reproduction of the problem
1. Enable or disable the ExpandAll() option.
2. The nodes are not expanded/collapsed when the TreeView is initialized.
A REPL sample for reproduction: https://netcorerepl.telerik.com/mSuMEPkZ10ZA6l8P00
### Expected/desired behavior
All nodes must be initially expanded when ExpandAll(true) is set.
### Environment
* **Telerik UI for ASP.NET Core version: 2024.2.514
* **Browser: [all]
### Bug report
The attributes set through the "HtmlAttributes", "ContentHtmlAttributes", and "LinkHtmlAttributes"methods are not applied to the TreeView items.
### Reproduction of the problem
1. Create a TreeView and set attributes by using the "HtmlAttributes", "ContentHtmlAttributes", "LinkHtmlAttributes"methods:
@(Html.Kendo().TreeView()
.Name("treeview-kendo2")
.Items(treeview =>
{
treeview.Add().Text("My Documents")
.SpriteCssClasses("k-icon k-i-globe")
.Expanded(true)
.Url("/")
.HtmlAttributes(new { @class = "fairydust1" })
.ContentHtmlAttributes(new { data_navigate = "navigate_content", @class = "trigger", title = "content_title" })
.LinkHtmlAttributes(new { data_navigate = "navigate_link", @class = "trigger", title = "content_link" });
})
)
2. Run the page and inspect the TreeView item.
### Expected/desired behavior
The attributes are serialized and rendered.
### Environment
* **Kendo UI version: 2021.2.616
* **jQuery version: 1.12.4
* **Browser: [all]
The Visible() API configuration is not applied correctly in the TreeView.
false
and notice that the item is not hidden.The Visible() API configuration is not applied correctly.
The Visible() API configuration should be applied correctly similar to how the Menu wrapper:
https://netcorerepl.telerik.com/cnvbcckN56kmV36Z07
The TreeView rendering in UI for ASP.NET MVC and UI for ASP.NET Core are not consistent. Setting the Id
configuration for an item in UI for ASP.NET MVC renders a data-id
attribute, that is missing in UI for ASP.NET Core.
@(Html.Kendo().TreeView()
.Name("treeview-kendo")
.TemplateId("treeview")
.Checkboxes(c=>c.CheckChildren(true))
.Items(treeview =>
{
treeview.Add()
.Text("My Documents")
.Id("MyId1");
treeview.Add()
.Text("My Documents 2")
.Id("MyId2");
})
)
When using the UI for ASP.NET Core the rendered <li>
element does not have the data-id
attribute that is present in UI for ASP.NET MVC
<li role="treeitem" class="k-item k-treeview-item k-first" data-uid="a3c937fd-1c4a-46a6-81e1-e53e1a2aeb6e" aria-checked="false" aria-selected="false" aria-expanded="false" data-expanded="false" aria-setsize="2" aria-level="1">
<div class="k-treeview-top k-treeview-top">
<span class="k-checkbox-wrapper" role="presentation">
<input id="_a3c937fd-1c4a-46a6-81e1-e53e1a2aeb6e" aria-hidden="true" type="checkbox" tabindex="-1" class="k-checkbox k-checkbox-md k-rounded-md">
</span>
<span class="k-treeview-leaf k-in">
<span class="k-treeview-leaf-text">My Documents</span>
</span>
</div>
</li>
Rendering should be consistent and the data-id
attribute added in UI for ASP.NET Core.
Use the HtmlAttributes
configuration to add the data-id
attribute
treeview.Add()
.HtmlAttributes(new {data_id = "MyId1"})
.Text("My Documents")
.Id("MyId1");
When a TreeView is bound to a new kendo.data.HierarchicalDataSource the binding of the widget breaks.
In the wrappers the following error is thrown:
Uncaught TypeError: Cannot read properties of undefined (reading 'length')
Review the behavior in this Telerik Core REPL.
The TreeView should bind to the new data set successfully.
The parent node's state remains "unchecked".
The parent node's state should be "indeterminate".
Workaround:
Attach a DataBound event handler to the TreeView:
<kendo-treeview name="DataRestrictionTree" load-on-demand="false" datatextfield="Name" on-data-bound="onDataBound" >
In the handler call the TreeView's updateIndeterminate API method:
function onDataBound(e) {
var treeview = $("#DataRestrictionTree").data("kendoTreeView");
treeview.updateIndeterminate();
}
