Property Value

A Type that represents the data type of the value displayed in an AutoGeneratedField object. The default isString.

Use the DataType property to specify the data type of the values displayed in an AutoGeneratedField object. The data type determines what type of control is rendered in an AutoGeneratedField object to display the value. For example, a check box control is displayed when the type is Boolean.

The following example demonstrates how to use the DataType property to specify the data type of the field values when programmatically creating an AutoGeneratedField object in a custom control that derives from the DetailsView control.

            // Set the properties of the AutoGeneratedField using
            // the values from the AutoGeneratedFieldProperties 
            // object contained in the fieldProperties parameter.
