我在文本框上有一個(gè)自動(dòng)填充擴(kuò)展器,它將記錄顯示為數(shù)據(jù)庫(kù)中的列表,但是我點(diǎn)擊了texbox并開(kāi)始輸入任何內(nèi)容.我的HTML代碼是

Enabled="True" TargetControlID="TextBox1" ServicePath="~/WebService.asmx"

ServiceMethod="GetCompletionList"

MinimumPrefixLength="2"

CompletionInterval="1000"

EnableCaching="true"

CompletionSetCount="20"

DelimiterCharacters=";, :"

ShowOnlyCurrentWordInCompletionListItem="true" >
