Glossary Item Box

Gets whether the contents of the control are valid.

Syntax

Visual Basic (Declaration) 
Public Overridable Function IsValid() As Boolean
Visual Basic (Usage)Copy Code
Dim instance As SuperEditBase
Dim value As Boolean
 
value = instance.IsValid()
C# 
public virtual bool IsValid()

Return Value

true if the contents of the control are valid; false otherwise

Remarks

Use this method to check whether the contents of a control are valid. If the method returns true, the contents are valid.

Usually, when the InvalidOption property is set to InvalidOption.ClearData, the IsValid property returns true because the invalid data has been cleared.

privatevoidForm1_Load(objectsender,System.EventArgse)
