how to add an icon-link in kendo ui treeview - kendo-ui

Here is my KendoUI tree view, I want to add 'edit' icon to all the nodes and then give a url to it, twhich takes the id of the node, and goes to edit page,
<script type="text/javascript">
var homogeneous = new kendo.data.HierarchicalDataSource({
transport: {
read: {
type:'POST',
url: rootURL + "Territory/AllTerritories",
dataType: "json"
}
},
schema: {
model: {
id: "ID",
hasChildren: "HasChildren",
children: homogeneous
}
}
});
$("#treeview").kendoTreeView({
dataSource: homogeneous,
dataTextField: "Name",
dataValueField: "ID",
});
</script>
I can see the TreeView being generated, Please help!

in your code little changes like this
<script type="text/javascript">
var homogeneous = new kendo.data.HierarchicalDataSource({
transport: {
read: {
type:'POST',
url: rootURL + "Territory/AllTerritories",
dataType: "json"
}
},
schema: {
model: {
id: "ID",
hasChildren: "HasChildren",
children: homogeneous,
image :"url"
}
}
});
$("#treeview").kendoTreeView({
dataSource: homogeneous,
dataTextField: "Name",
dataValueField: "ID",
dataImageUrlField: "image"
});
</script>

Use Kendo UI Template for that:
<script id="treeview-template" type="text/kendo-ui-template">
<a class='show-link' href='\#'><image src="/imageUrl"></a>
</script>
$("#treeview").kendoTreeView({
dataSource: homogeneous,
dataTextField: "Name",
dataValueField: "ID",
template: kendo.template($("#treeview-template").html()
});

Kendo UI Multiselect Tag mode - filter based on typed value not passing the typed text to server

This is the code which I am using to bind Multiselect to listbox in javascript. I am not where I am missing, I am not receiving the typed text in ajax call to get values. The method gets called in the controller side and the string parameter which I have returns null.
Implemented based on URL: https://demos.telerik.com/kendo-ui/multiselect/addnewitem
$("#Tags").kendoMultiSelect({
placeholder: "Select your tags",
dataTextField: "Name",
dataValueField: "Id",
autoBind: false,
maxSelectedItems: 5,
minLength: 3,
delay: 2000,
//filter: "startswith",
dataSource: {
transport: {
read: {
url: "/Support/Ticket/GetTags",
dataType: "json"
}
},
serverFiltering:true
}
});
Controller
public JsonResult GetTags(string text)
{
List<Tag> tags = _tagRepository.GetAll(text).ToList();
return Json(tags);
}
As mentioned here https://www.telerik.com/forums/server-filtering-not-working-as-expected#KXcqO6xHoE6NxGuL0T2ZoQ, I think you need to add return data option
$(document).ready(function () {
$("#products").kendoMultiSelect({
placeholder: "Select products...",
dataTextField: "ProductName",
dataValueField: "ProductID",
dataSource: {
type: "odata",
serverFiltering: true,
transport: {
read: {
url: "http://demos.kendoui.com/service/Northwind.svc/Products",
data: function () {
return {
text: $("#products").data('kendoMultiSelect').input.val()
};
}
}
}
}
});
});

Bind Kendo Grid data with dropdown value

I have kendo dropdownlist on page which is fetching results from database as below. I also have a grid at the same page at same time which needs kendo dropdownlist value i.e the value from years dropdownlist but I am unable to get it at the same time.This is how I am following. Where I am doing wrong.
<script type="text/javascript">
var GridUrl;
$("#Years").kendoDropDownList({
dataTextField: "Name",
dataValueField: "Id",
dataSource: {
transport: {
read: {
dataType: "json",
url: "../../Service/GetYears"
}
}
}
});
$(document).ready(function () {
BindGridData();
GridUrl = '#Url.Action("Read", "Home")';
});
function BindGridData()
{
GridDataSource = new kendo.data.DataSource({
type: "aspnetmvc-ajax",
serverFiltering: true,
serverPaging: true,
serverSorting: true,
pageSize: 10,
transport: {
read: {
url: GridUrl,
data: { year: $('#Years').val() }
}
},
schema: {
data: "Data", total: "Total"
}
});
}
Changing line to this
year: $('#Years').data("kendoDropDownList").value()
should do a trick. You need to get instance of kendoDropDownListwidget in order to get its value. You need to do so, because kendoDropDownListwidget value is not saved directly into html element
First of all, you need to move the initialisation of the kendoDropDownList inside the document ready function. If you don't you may end up refering to elements that are not loaded (yet).
The second change that should be done is how you get the value from the kendoDropDownList. Usually, you should refer to the widget instead of the DOM element: $('#Years').data("kendoDropDownList").value()
Finally, you didn't mention how and when your grid was binded but you may want to refresh the grid data if the user change the dropdown value. If it's the case, you may want to use change event of the dropdown to refresh the grid data.
$(document).ready(function () {
$("#Years").kendoDropDownList({
dataTextField: "Name",
dataValueField: "Id",
dataSource: {
transport: {
read: {
dataType: "json",
url: "../../Service/GetYears"
}
}
},
change: function(e) {
$("#YourGrid").data("kendoGrid").dataSource.read();
}
});
BindGridData();
GridUrl = '#Url.Action("Read", "Home")';
});
function BindGridData() {
GridDataSource = new kendo.data.DataSource({
type: "aspnetmvc-ajax",
serverFiltering: true,
serverPaging: true,
serverSorting: true,
pageSize: 10,
transport: {
read: {
url: GridUrl,
data: { year: $('#Years').data("kendoDropDownList").value() }
}
},
schema: {
data: "Data", total: "Total"
}
});
}
