Property Value

Type: System.Web.UI.ITemplate

A System.Web.UI.ITemplate-implemented object that contains the template for displaying an item in edit mode in a TemplateField. The default is null, which indicates that this property is not set.

Use the EditItemTemplate property to specify the custom content displayed for an item that is in edit mode in a TemplateField object. Define the content by creating a template that specifies how an item in edit mode is rendered. The EditItemTemplate property usually contains input controls for the user to modify a value in a data source.

To specify a template, first place opening and closing <EditItemTemplate> tags between the opening and closing tags of the <TemplateField> element. Next, add the custom content between the opening and closing <EditItemTemplate> 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.

The following code example demonstrates how to use the EditItemTemplate property to create a custom template for an item in edit mode in a TemplateField field column of a GridView control. The template contains validation server controls to prevent a user from leaving a value field empty.
