Default State
You can configure a default state of the Telerik UI ExpansionPanel for ASP.NET Core by using the Disabled, Expanded, Toggleable and Animation properties.
Disabled State
To disable the component and prevent the user to expand or collapse the panel, set the Disabled property to true.
@(Html.Kendo().ExpansionPanel()
.Name("brazil")
.Title("Brazil")
.SubTitle("South America")
.Disabled(true)
.Content("The word 'Brazil' likely comes from the Portuguese word for brazilwood, a tree that once grew plentifully along the Brazilian coast. In Portuguese, brazilwood is called pau-brasil, with the word brasil commonly given the etymology 'red like an ember', formed from brasa ('ember') and the suffix -il (from -iculum or -ilium).")
)
<kendo-expansionpanel name="brazil" title="Brazil" sub-title="South America" disabled="true">
