c# – 无法找到按钮调用的方法

现在我的问题是我不明白表单是如何打开的.

这是在SuiviPlanFormation.aspx中创建按钮的位置

<asp:Button ID="btnComplete" runat ="server" Text ="B212"  
            CommandArgument ='<%# Eval("Code") %>' CommandName ="Select" 
            CssClass="button" 
            Enabled='<%# not Eval("Status").equals("green") %>'/>

这是单击B212按钮FormationForm.aspx时似乎打开的表单.代码显然是从Page_Load开始的.

我似乎无法弄清楚如何调用这种形式.有人可以赐教吗？
