Template
2 Mar 20256 minutes to read
The TreeView control allows you to customize the look of TreeView nodes by using the nodeTemplate
property. This property accepts either a template string
or an HTML element ID.
In the following sample, employee information such as employee photo, name, and designation has been included using the nodeTemplate
property.
The template expression should be provided inside the ${...}
interpolation syntax.
<ejs-treeview id="treedata" cssClass="custom" nodeTemplate="@Html.Raw("<div><img class=\"eimage\" src=\"https://ej2.syncfusion.com/demos/src/images/employees/${Image}.png\" alt=\"employee\"/><div class=\"ename\"> ${name} </div><div class=\"ejob\"> ${Job} </div></div>")">
<e-treeview-fields dataSource="ViewBag.data" id="id" parentId="pid" text="name" hasChildren="HasChild" expanded="Expanded"></e-treeview-fields>
</ejs-treeview>
<style>
.custom.e-treeview .e-fullrow {
height: 72px;
}
.custom.e-treeview .e-list-text {
line-height: normal;

.eimage {

padding: 11px 16px 11px 0;
