Getting "JavaScript runtime error: Sys.ArgumentUndefinedException: Value cannot be undefined.
Parameter name: type"
same code worked with:
VS2005, framework 2, Ajaxcontroltoolkit v1.0.10920
generates error with:
VS2010, Framework 4.0, Ajaxcontroltoolkit v 4.1.7.1213
<asp:AutoCompleteExtender runat="server" ID="aceBadge" ServiceMethod="GetBadgeList" ServicePath="~/SysManagerSvc.asmx"
MinimumPrefixLength="2" TargetControlID="txtByBadge" CompletionInterval="1000" CompletionSetCount="20" Enabled="true" UseContextKey="false" />
Is there a missing property declaration that is mandatory?
Comments: Please upgrade to the latest version of AJAX Control Toolkit v15.1. If the problem remains, feel free to post a new issue.
