DataGridViewCellStyle.IsDataSourceNullValueDefault Property

Gets a value indicating whether the DataSourceNullValue property has been set.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

[BrowsableAttribute(false)]
public bool IsDataSourceNullValueDefault { get; }

Property Value

Type: System.Boolean
true if the value of the DataSourceNullValue property is the default value; otherwise, false.

Use this property to determine whether the DataSourceNullValue property has been explicitly set without having to store its default value for comparison. This is useful because the DataSourceNullValue property has a non-empty default value, unlike most other DataGridViewCellStyle properties, which have default values such as null, Empty, or NotSet.
