Currency TextBox crashing

When deleting a character from the Currency TextBox an unhandled exception occurs: Method: App.MainForm - Void Main() Message: Unhandled Exception System.ArgumentException: String cannot be of zero length. Parameter name: oldValue at System.Text.StringBuilder.Replace(String oldValue, String newValue, Int32 startIndex, Int32 count) at System.Text.StringBuilder.Replace(String oldValue, String newValue) at Syncfusion.Windows.Forms.Tools.CurrencyTextBox.IsDataPosition(String formattedText, Int32 position) at Syncfusion.Windows.Forms.Tools.NumberTextBoxBase.HandleDeleteKey() at Syncfusion.Windows.Forms.Tools.NumberTextBoxBase.Delete() at Syncfusion.Windows.Forms.Tools.NumberTextBoxBase.HandleMenuDeleteClick(Object sender, EventArgs ea) at System.Windows.Forms.MenuItem.OnClick(EventArgs e) at System.Windows.Forms.MenuItem.ShortcutClick() at System.Windows.Forms.Menu.ProcessCmdKey(Message& msg, Keys keyData) at System.Windows.Forms.Control.ProcessCmdKey(Message& msg, Keys keyData) at System.Windows.Forms.Control.PreProcessMessage(Message& msg) at System.Windows.Forms.ThreadContext.System.Windows.Forms.UnsafeNativeMethods+IMsoComponent.FPreTranslateMessage(MSG& msg) at System.Windows.Forms.ComponentManager.System.Windows.Forms.UnsafeNativeMethods+IMsoComponentManager.FPushMessageLoop(Int32 dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run(Form mainForm) at App.MainForm.Main() in c:\..path..\mainform.cs:line 798 How do I prevent this from happening? It only seems to happen when I click in the cell and then delete a single character. I also have ValidateValue / NumberRequired set to true. This is v.2.1.0.9.

Hi Frances, This is a know issue with version 2.1 but it has been fixed in the latest version. Please create a Direc-Trac incident to receive the download instructions for Version 3.0. Thanks.
