MaskedTextBox.IsOverwriteMode MaskedTextBox.IsOverwriteMode MaskedTextBox.IsOverwriteMode MaskedTextBox.IsOverwriteMode Property

Definition

Gets a value that specifies whether new user input overwrites existing input.

public:
 property bool IsOverwriteMode { bool get(); };
[System.ComponentModel.Browsable(false)]
public bool IsOverwriteMode { get; }
member this.IsOverwriteMode : bool
Public ReadOnly Property IsOverwriteMode As Boolean

Property Value

true if MaskedTextBox will overwrite existing characters as the user enters new ones; false if MaskedTextBox will shift existing characters forward. The default is false.

Remarks

IsOverwriteMode takes into account both the value of the InsertKeyMode property and the state of the user's keyboard. If InsertKeyMode is set to either Insert or Overwrite, IsOverwriteMode will return false or true, respectively. If InsertKeyMode is set to Default, it will return the state of the INSERT key.

When IsOverwriteMode is false, MaskedTextBox will reject as invalid any character entry that would result in a violation anywhere in the mask. In explanation, if inserting a character would cause a character to be shifted over into a mask position where it would not be valid, the character insertion will be rejected.
