Templates
The ComboBox provides full control over the way an item, a selected value, or a pop-up header is rendered through the Kendo UI for jQuery templates.
For more information on the capabilities and syntax of the templates, refer to this documentation article. For a runnable example, refer to the demo on customizing the templates in the ComboBox.
Basic Usage
The following example demonstrates how to customize the ComboBox by referencing a script tag by its id
.
@(Html.Kendo().ComboBox()
.Name("customers")
.DataTextField("ContactName")
.DataValueField("CustomerID")
.TemplateId("itemTemplate") // Reference to the template.
.DataSource(source =>
{
source.Read(read =>
{
read.Action("Template_GetCustomers", "ComboBox");
});
})
)
The following example demonstrates how to customize the ComboBox by declaring an inline string.
@(Html.Kendo().ComboBox()
.Name("customers")
.DataTextField("ContactName")
.DataValueField("CustomerID")
.Template("<span><h3>#: data.ContactName #</h3><p>#: data.CompanyName #</p></span>")
.DataSource(source =>
{
source.Read(read =>
{
read.Action("Template_GetCustomers", "ComboBox");
});
})
)
Item Template
The item template manages the way the list items of a ComboBox are rendered.
The following example demonstrates how to define an item template and how to evaluate it against the dataItem.
@(Html.Kendo().DropDownList()
.Name("customers")
.DataTextField("ContactName")
.DataValueField("CustomerID")
.TemplateId("itemTemplate") // Reference to the template.
.DataSource(source =>
{
source.Read(read =>
{
read.Action("Template_GetCustomers", "ComboBox");
});
})
)
Header Templates
The header template manages the way the popup header of a ComboBox is rendered.
@(Html.Kendo().ComboBox()
.Name("customers")
.DataTextField("ContactName")
.DataValueField("CustomerID")
.HeaderTemplateId("headerTemplate") // Reference to the template.
.DataSource(source =>
{
source.Read(read =>
{
read.Action("Template_GetCustomers", "ComboBox");
});
})
)
Footer Templates
The footer template manages the way the popup footer of a ComboBox is rendered. The footer is re-rendered on every change of the Data Source. The context of the template is the widget itself.
@(Html.Kendo().ComboBox()
.Name("customers")
.DataTextField("ContactName")
.DataValueField("CustomerID")
.FooterTemplateId("footerTemplate") // Reference to the template.
.DataSource(source =>
{
source.Read(read =>
{
read.Action("Template_GetCustomers", "ComboBox");
});
})
)
No-Data Templates
The ComboBox displays noDataTemplate
in the popup when the data source is empty.
@(Html.Kendo().ComboBox()
.Name("customers")
.DataTextField("ContactName")
.DataValueField("CustomerID")
.NoDataTemplateId("noDataTemplate") //Reference to the template
.DataSource(source =>
{
source.Read(read =>
{
read.Action("Template_GetCustomers", "ComboBox");
});
})
)
