Remarks

Sometimes the user may enter an empty string for a field value when updating or inserting records. Use the ImageField.ConvertEmptyStringToNull property to specify whether an empty string value is automatically converted to null when the data field is updated in the data source

Note:

The System.Web.UI.WebControls.ImageField class displays null as empty strings by default. To display a different value, set the ImageField.NullDisplayText property.
