Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

[TemplateContainerAttribute(typeof(IDataItemContainer), BindingDirection.TwoWay)] 
public virtual ITemplate InsertItemTemplate { get; set; }
/** @property */
public ITemplate get_InsertItemTemplate ()

/** @property */
public void set_InsertItemTemplate (ITemplate value)

public function get InsertItemTemplate () : ITemplate

public function set InsertItemTemplate (value : ITemplate)

Not applicable.

Property Value

A System.Web.UI.ITemplate-implemented object that contains the template for displaying an item in insert mode in a TemplateField. The default is a null reference (Nothing in Visual Basic), which indicates that this property is not set.

Use the InsertItemTemplate property to specify the custom content displayed for an item in insert mode in a TemplateField object. Define the content by creating a template that specifies how the item in insert mode is rendered.

To specify a template, first place opening and closing <InsertItemTemplate> tags between the opening and closing tags of the <TemplateField> element. Next, add the custom content between the opening and closing <InsertItemTemplate> tags. The content can be as simple as plain text or more complex (embedding other controls in the template, for example).

To programmatically access a control defined in a template, first determine which TableCell object in the data-bound control contains the control. Next, use the Controls collection of the TableCell object to access the control. You can also use the FindControl method of the TableCell object to find the control, if the control has an ID property specified.

NoteNote:

Not all data-bound controls support this template This template is supported only by data-bound controls that allow you to insert a record, such as the DetailsView control.

The following code example demonstrates how to use the InsertItemTemplate property to create a custom template for an item in insert mode in a TemplateField field row in a DetailsView control. The template displays a DropDownList control that allows the user to select a value from a predefined list.
