Hi,

I've created a new ComboBoxAdv, with AllowNewText set to false and a datasource: comboBoxAdv1.DataSource = new string[] { "123", "456", "789" };

When I move the cursor to the first position of the combobox and press backspace, an exception is thrown. How do I avoid this?

System.NullReferenceException was unhandled
Message="Object reference not set to an instance of an object."
Source="Syncfusion.Shared.Base"
StackTrace:
at Syncfusion.Windows.Forms.Tools.ComboBoxBase.FindItem(String prefix, Boolean select, Int32 start, Boolean ignoreCase)
at Syncfusion.Windows.Forms.Tools.ComboBoxBaseDataBound.PerformShowPopUpAfterDel(String strAfterDel)
...

Regards,
Mattias
