Description
How can I change the Expand and Collapse icons in the Kendo UI for jQuery Hierarchy Grid and add text to the icons?
Solution
To achieve the desired scenario:
- Update the Expand and Collapse icons by using the following CSS rules. For the full list of the Kendo UI Web Font Icons, refer to the list of Font icons.
<style>
.k-i-expand:before {
content: "\e11e";
}
.k-i-collapse:before {
content: "\e121";
}
</style>
- To add text to the icons, write custom logic in the
dataBound,detailExpand, anddetailCollapseevent handlers.
The following example demonstrates the full implementation of the suggested approach.
<div id="grid"></div>
<script>
$(document).ready(function() {
var element = $("#grid").kendoGrid({
dataSource: {
type: "odata",
transport: {
read: "https://demos.telerik.com/kendo-ui/service/Northwind.svc/Employees"
},
pageSize: 6,
serverPaging: true,
serverSorting: true
},
height: 600,
sortable: true,
pageable: true,
detailInit: detailInit,
dataBound: function() {
this.tbody.find('.k-hierarchy-cell').each(function(_,x){
x= $(x);
x.prepend("<span class='expand'>Expand</span>")
});
},
detailExpand: function(e) {
this.tbody.find('.expand').each(function(_,x){
x= $(x);
x.text("Collapse");
x.removeClass("expand").addClass("collapse");
});
},
detailCollapse: function(e) {
this.tbody.find('.collapse').each(function(_,x){
x= $(x);
x.text("Expand");
x.removeClass("collapse").addClass("expand");
});
},
columns: [
{
field: "FirstName",
title: "First Name",
width: "110px"
},
{
field: "LastName",
title: "Last Name",
width: "110px"
},
{
field: "Country",
width: "110px"
},
{
field: "City",
width: "110px"
},
{
field: "Title",
width: "110px",
}
]
});
});
function detailInit(e) {
$("<div/>").appendTo(e.detailCell).kendoGrid({
dataSource: {
type: "odata",
transport: {
read: "https://demos.telerik.com/kendo-ui/service/Northwind.svc/Orders"
},
serverPaging: true,
serverSorting: true,
serverFiltering: true,
pageSize: 10,
filter: { field: "EmployeeID", operator: "eq", value: e.data.EmployeeID }
},
scrollable: false,
sortable: true,
pageable: true,
columns: [
{ field: "OrderID", width: "110px" },
{ field: "ShipCountry", title:"Ship Country", width: "110px" },
{ field: "ShipAddress", title:"Ship Address", width: "110px" },
{ field: "ShipName", title: "Ship Name", width: "300px" }
]
});
}
</script>
<style>
/* Update Expand icon */
.k-i-expand:before {
content: "\e11e";
}
/* Update Collapse icon */
.k-i-collapse:before {
content: "\e121";
}
/* Set a width for the hierarchy column, otherwise the column you swap it with will be shrunk. */
.k-grid .k-hierarchy-col {
width: 60px;
}
/* Set inline display to the icon to have the text and the icon on the same line */
.k-grid .k-hierarchy-cell>.k-icon{
display: inline;
}
</style>
