IsValid Method (SuperEditBase)
Example 


Gets whether the contents of the control are valid.
Syntax
'Declaration
 
Public Overridable Function IsValid() As Boolean
'Usage
 
Dim instance As SuperEditBase
Dim value As Boolean
 
value = instance.IsValid()
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.

Example
privatevoidForm1_Load(objectsender,System.EventArgse)
{
control.Text="Hi";
control.InvalidOption=FarPoint.Win.InvalidOption.ShowData;
}

privatevoidcontrol_MouseDown(objectsender,System.Windows.Forms.MouseEventArgse)
{
boolbvalue;
bvalue=control.IsValid();
if(bvalue==false)
{
control.Value=500;
}
}
PrivateSubForm1_Load(ByValsenderAsSystem.Object,ByValeAsSystem.EventArgs)HandlesMyBase.Load
control.Text="Hi"
control.InvalidOption=FarPoint.Win.InvalidOption.ShowData
EndSub

PrivateSubcontrol_MouseDown(ByValsenderAsObject,ByValeAsSystem.Windows.Forms.MouseEventArgs)HandlesCurrency1.MouseDown
DimbvalueAsBoolean
