1、
现在这里查找是否有您的班级：<br />
学校名称：<asp:DropDownList ID="ddlxuexiao" runat="server" DataSourceID="sqldsCollege"
DataTextField="college" DataValueField="college" Width="250px" AutoPostBack="True" OnSelectedIndexChanged="ddlxuexiao_SelectedIndexChanged">
</asp:DropDownList>
<br />
入学年份：<asp:DropDownList ID="ddlnian" runat="server" DataSourceID="sqldsComeYear"
DataTextField="comeyear" DataValueField="comeyear">
</asp:DropDownList>
<br />
<asp:Button ID="btnListClassName" runat="server" Text="列出学校" OnClick="btnListClassName_Click" /><div id="listclass" runat ="server"></div><br />
<div id="memberClass"></div><asp:SqlDataSource ID="sqldsComeYear" runat="server" ConnectionString="<%$ ConnectionStrings:dsn %>"
SelectCommand="SELECT [comeyear] FROM [tbanji] WHERE ([college] = @college)">
<SelectParameters>
<asp:ControlParameter ControlID="ddlxuexiao" Name="college" PropertyName="SelectedValue"
Type="String" />
</SelectParameters>
</asp:SqlDataSource>
<asp:SqlDataSource ID="sqldsCollege" runat="server" ConnectionString="<%$ ConnectionStrings:dsn %>"
SelectCommand="select distinct college from tbanji"></asp:SqlDataSource>
<br />
<br />
2、如果没有列出您的班级，请创建班级：<br />
学校名称：<asp:DropDownList ID="ddlCollege" runat="server" DataSourceID="sqldsCollege" DataTextField="college"
DataValueField="college" Width="262px">
<asp:ListItem>其它</asp:ListItem>
</asp:DropDownList>
<br />
或手动输入：<asp:TextBox ID="tbCollege" runat="server" Width="172px"></asp:TextBox>
<br />
入学年份：<asp:TextBox ID="tbComeYear" runat="server" Width="62px"></asp:TextBox><br />
班级名称：<asp:TextBox ID="tbClassname" runat="server" Width="186px"></asp:TextBox><br />
<br />
<asp:Button ID="btnAddClassName" runat="server" OnClick="btnAddClassName_Click" Text="添加班级" /></div>
</form>
</body>
