Feature Request
DataSource HasChildren Handler
Good Day,
We would like to submit a feature request to add a handler method for the `HasChildren` property of a HierarchicalDatasource for the MVC Wrappers. It currently only supports a string field name even though the Javascript api can handle a function. We are currently working around this by using the wrapper to define our widget, and then in a kendo.syncready we are creating a datasource and then using setOptions of the widget to achieve the same effect, which should be in the wrapper already.
Example code snippet:
<script>
kendo.syncReady(function() {
let panelBar = jQuery("#@panelBarId").getKendoPanelBar();
if (!panelBar) {
return;
}
var ds = new kendo.data.HierarchicalDataSource({
transport: {
read: {
url: '@Url.Action("LoadPanelBarResults", "Home")',
data: function (){
return resultsPanelbarData('@Html.Raw(searchTagString)', '@Html.Raw(parentTagString)');
}
}
},
schema: {
model: {
id: 'IdString',
hasChildren: hasChildrenFunction
}
}
});
panelBar.setOptions({dataSource: ds});
});
</script>We hope this request is clear, let us know if there are any questions of the use of this scenario.
Thankyou for your time,
Regards,
Nathan
