CardViewColumn.DataItemTemplate Property

Gets or sets a template for displaying data cells within the current column.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v20.2.dll

Declaration

[DefaultValue(null)]
public virtual ITemplate DataItemTemplate { get; set; }
<DefaultValue(Nothing)>
Public Overridable Property DataItemTemplate As ITemplate

Property Value

Type Default Description
ITemplate

null

An object that implements the ITemplate interface.

Remarks

To provide a common template for displaying data cells within the ASPxCardView, use the CardViewTemplates.DataItem property.

NOTE

Once a template defined via the DataItemTemplate property is created within a control, it is instantiated within a container object of the CardViewDataItemTemplateContainer type. This container object exposes a set of specific properties to which the template's child controls can be bound.

Examples

Search results contained in templates are not highlighted by default, but you can highlight them manually. The following example wraps the search results in a <span> tag with the "dxcvHL" class. Note that this is a basic example that illustrates how to process simple requests. If you create composite criteria, it is necessary to perform additional operations to parse the search text.
