DataGridColumnStyle.EnterNullValue Method

  • Reference

Definition

Namespace:
System.Windows.Forms
Assembly:
System.Windows.Forms.dll

Enters a Value into the column.

protected public:
 virtual void EnterNullValue();
protected internal virtual void EnterNullValue ();
abstract member EnterNullValue : unit -> unit
override this.EnterNullValue : unit -> unit
Protected Friend Overridable Sub EnterNullValue ()

Examples

The following code example shows a possible override of the EnterNullValue method.

Overrides Protected Sub EnterNullValue()
   ' Enter the NullText value into a hosted TextBox control.
   Me.TextBox.Text = Me.NullText
End Sub

Remarks

This method is called when the user presses ALT+0 to allow a column to enter the appropriate null value. For example, when called on a DataGridTextBoxColumn, the appropriate NullText value is inserted into the column.

The EnterNullValue has no default behavior. When inheriting from DataGridColumnStyle, override the method to enter null in a column.
