The GridView and DetailsView) to display the value of a Boolean data field in a check box. The object is displayed differently depending on the data-bound control in which it is used. For example, the GridView control displays a object as a column, while the DetailsView control displays it as a row.class is used by data-bound controls (such as
A check box is disabled (read-only) until the data-bound control displays a record that contains the check box in edit mode. For more information on how to put a record into edit mode, see the documentation for the parent control that contains theobject.
To specify the field to display in a DataField property with the field's name.object, set the
Because a check box can display only a selected or an unselected state, a Parse.object can be bound only to a field with a Boolean data type or a string that can be parsed by
You can display a caption next to each check box by setting the Text property. A object is hidden in a data-bound control when the Visible property is set to false. To prevent the value of a field from being modified in edit mode, set the ReadOnly property to true. In data-bound controls that support inserting records (such as the DetailsView control), you can hide a object in insert mode by setting the InsertVisible property to false.
You can customize the header and footer sections of a HeaderText or FooterText properties, respectively. Instead of displaying text in the header section, you can display an image by setting the HeaderImageUrl property. The header section can be hidden in the object by setting the ShowHeader property to false.object. To display a caption in the header or footer sections, set the
Some data-bound controls (such as the GridView control) can show or hide only the entire header section of the control. These data-bound controls do not support the ShowHeader property for an individual bound field. To show or hide the entire header section of a data-bound control (if available), use the control's ShowHeader property.
You also can customize the appearance of theobject (font color, background color, and so on) by setting the style properties for the different parts of the field. The following table lists the different style properties.
The style settings for the child Web server controls of theobject.
The style settings for the footer section of theobject.
The style settings for the header section of theobject.
The style settings for the data items in theobject.
