autocomplete

[Doug Finke]

I am using a textbox for XPath Expressions. When I type in //MarketState/MarketKey[Instrument1] I get the following stacktrace. See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box. ************** Exception Text ************** System.Data.ConstraintException: Column ''Column0'' is constrained to be unique. Value ''//MarketState/MarketKey[Instrument2]'' is already present. at System.Data.DataTable.InsertRow(DataRow row, Int32 proposedID, Int32 pos) at System.Data.DataRowCollection.Add(DataRow row) at Syncfusion.Windows.Forms.Tools.AutoComplete.AddHistoryItem(String newItemText, Int32 imageIndexValue) at Syncfusion.Windows.Forms.Tools.AutoComplete.AddHistoryItem(String newItem) at Syncfusion.Windows.Forms.Tools.AutoComplete.AddItemOnValidate(Control editControl) at Syncfusion.Windows.Forms.Tools.AutoComplete.HandleControlValidated(Object sender, EventArgs e) at System.EventHandler.Invoke(Object sender, EventArgs e) at System.Windows.Forms.Control.OnValidated(EventArgs e) at System.Windows.Forms.Control.NotifyValidated() at System.Windows.Forms.ContainerControl.ValidateThroughAncestor(Control ancestorControl) ************** Loaded Assemblies ************** mscorlib Assembly Version: 1.0.3300.0 Win32 Version: 1.0.3705.288 CodeBase: file:///c:/windows/microsoft.net/framework/v1.0.3705/mscorlib.dll ---------------------------------------- XPathEval_CS Assembly Version: 1.0.1547.38414 Win32 Version: 1.0.1547.38414 CodeBase: file:///C:/MS%20Press%20Books/XMLProgNET/Chap06/XPathEvaluator/C%23/XPathEval_CS/bin/Debug/XPathEval_CS.exe ---------------------------------------- System.Windows.Forms Assembly Version: 1.0.3300.0 Win32 Version: 1.0.3705.288 CodeBase: file:///c:/windows/assembly/gac/system.windows.forms/1.0.3300.0__b77a5c561934e089/system.windows.forms.dll ---------------------------------------- System Assembly Version: 1.0.3300.0 Win32 Version: 1.0.3705.288 CodeBase: file:///c:/windows/assembly/gac/system/1.0.3300.0__b77a5c561934e089/system.dll ---------------------------------------- System.Drawing Assembly Version: 1.0.3300.0 Win32 Version: 1.0.3705.288 CodeBase: file:///c:/windows/assembly/gac/system.drawing/1.0.3300.0__b03f5f7f11d50a3a/system.drawing.dll ---------------------------------------- Syncfusion.Tools Assembly Version: 2.0.3.0 Win32 Version: 2.0.3.0 CodeBase: file:///c:/windows/assembly/gac/syncfusion.tools/2.0.3.0__3d67ed1f87d44c89/syncfusion.tools.dll ---------------------------------------- Syncfusion.Shared Assembly Version: 2.0.3.0 Win32 Version: 2.0.3.0 CodeBase: file:///c:/windows/assembly/gac/syncfusion.shared/2.0.3.0__3d67ed1f87d44c89/syncfusion.shared.dll ---------------------------------------- System.Data Assembly Version: 1.0.3300.0 Win32 Version: 1.0.3705.288 CodeBase: file:///c:/windows/assembly/gac/system.data/1.0.3300.0__b77a5c561934e089/system.data.dll ---------------------------------------- System.Xml Assembly Version: 1.0.3300.0 Win32 Version: 1.0.3705.288 CodeBase: file:///c:/windows/assembly/gac/system.xml/1.0.3300.0__b77a5c561934e089/system.xml.dll ---------------------------------------- System.Runtime.Serialization.Formatters.Soap Assembly Version: 1.0.3300.0 Win32 Version: 1.0.3705.288 CodeBase: file:///c:/windows/assembly/gac/system.runtime.serialization.formatters.soap/1.0.3300.0__b03f5f7f11d50a3a/system.runtime.serialization.formatters.soap.dll ---------------------------------------- ************** JIT Debugging ************** To enable just in time (JIT) debugging, the config file for this application or machine (machine.config) must have the jitDebugging value set in the system.windows.forms section.

Hi Doug,

Thanks for bringing this to our attention. I have tested for this issue and seen that the AutoComplete does cause a crash in the above scenario. The development team has been notified in this regard, and we will try our best to fix it at the earliest. We appreciate your feedback, and thanks for choosing Syncfusion products.
