我是否可以像dropdownlist那样绑定文本框，这意味着在dropdownlist中，我们可以设置datatextfield以显示文本，而datavaluefield可以将值插入数据库. 我必须使用文本框，我已经向文本框添加了自动完成ajax工具包扩展程序.我只显示学生姓名，但单击按钮后，我必须在数据库中插入学生的SID，而不是学生姓名.我在Google上搜索谷歌，他们告诉我使用自动填充扩展程序的OnClientItemSelected.

Can I bind textbox like dropdownlist means in dropdownlist we can set datatextfield to show text and datavaluefield to insert value into database. I have to do using textbox,I have added Autocomplete ajax toolkit extender to textbox. I am showing only Student Names but on click of button i have to insert SID of student not student name into the database.I search google they tell me use OnClientItemSelected of Autocomplete extender.How can i do any idea regarding this.

[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()] public static string[] Getdata(string prefixText, int count, string contextKey) { strSQL = "SELECT SID,Student_Name FROM Student_Master WHERE Student_Name Like '" + prefixText + "%'"; DataTable dataTablePatient_Master = null; dataTablePatient_Master = objSqlDbComm.ExecuteDatasetQuery(strSQL).Tables[0]; List<String> list = new List<String>(); foreach(DataRow dr in dataTablePatient_Master.Rows) { list.Add(dr["Student_Name"].ToString()); } return list.ToArray(); }

<asp:TextBox ID="txtStudentName" AutoCompleteType="Disabled" CssClass="csstextbox" runat="server"></asp:TextBox> <asp:AutoCompleteExtender ID="txtStudentName_AutoCompleteExtender" runat="server" ServiceMethod="Getdata" OnClientItemSelected="OnItemSelected" CompletionListCssClass="cssautocompletetextbox" MinimumPrefixLength="1" CompletionInterval="1000" EnableCaching="true" CompletionSetCount="1" TargetControlID="txtStudentName" UseContextKey="True"> </asp:AutoCompleteExtender>
