C# ASP.NET C使用ITemplate在代码端动态生成复选框触发
我想做一个里克特秤 问题1： 将创建在文本框中输入的列数。列的名称从1开始到给定的数字。单击使用itemplate创建的复选框不会触发 问题2： 假设我们没有费心去触发复选框。我怎样才能得到复选框？即使我使用for导航网格，也无法接收它 注意：保存选择后，必须执行更新和删除过程。在保存期间，它应该浏览网格并获得标记的复选框 SQL C:AddTemplateToGridView.cs WebForm1.aspx.cs WebForm1.aspx设计源代码C# ASP.NET C使用ITemplate在代码端动态生成复选框触发,c#,asp.net,gridview,datatable,datagrid,C#,Asp.net,Gridview,Datatable,Datagrid,我想做一个里克特秤 问题1： 将创建在文本框中输入的列数。列的名称从1开始到给定的数字。单击使用itemplate创建的复选框不会触发 问题2： 假设我们没有费心去触发复选框。我怎样才能得到复选框？即使我使用for导航网格，也无法接收它 注意：保存选择后，必须执行更新和删除过程。在保存期间，它应该浏览网格并获得标记的复选框 SQL C:AddTemplateToGridView.cs WebForm1.aspx.cs WebForm1.aspx设计源代码 public class AddTem
