BaseFieldControl.DisplayTemplateName Property

Gets or sets the name of the template that can be used to control the rendering of the BaseFieldControl object in display mode; that is, when it is not on a New or Edit form.

Namespace:  Microsoft.SharePoint.WebControls
Assembly:  Microsoft.SharePoint (in Microsoft.SharePoint.dll)

Syntax

Public Overridable Property DisplayTemplateName As String
    Get
    Set

Dim instance As BaseFieldControl
Dim value As String

value = instance.DisplayTemplateName

instance.DisplayTemplateName = value
public virtual string DisplayTemplateName { get; set; }

Property Value

Type: System.String
A String that names a rendering template.

Remarks

For most field controls, this property is null because rendering in Display mode is easier when it is configured with a RenderPattern in the field definition. But if your field is sufficiently complex or requires special data access or processing before its value can be rendered, using an ITemplate might be preferable.

With the default implementation, the default value of DisplayTemplateName is a null reference (Nothing in Visual Basic). If it is set to a non-null value and DisplayTemplate has not been explicitly set, DisplayTemplate returns the ITemplate that is named by DisplayTemplateName. But if DisplayTemplatehas been set, its default getter ignores the value of DisplayTemplateName.

Notes to Inheritors

With their default implementations, it is possible for DisplayTemplate to be set to a template other than the one that is named by DisplayTemplateName. Hence, with the default implementations, when your code sets DisplayTemplate, it should also set DisplayTemplateName to the name of the same ITemplate. Similarly, when your code sets DisplayTemplateName, it should also set DisplayTemplate to the same ITemplate. If you do not enforce logical consistency in this way and the two properties have inconsistent values at render time, DisplayTemplate determines the template that is used for rendering the field.

If you decide to use a template for rendering in Display mode, you can have your override of the getter of ControlTemplate return DisplayTemplate when the control mode is Display. Alternatively, your override of CreateChildControls can set TemplateName to DisplayTemplateName when the control mode is Display.
