问题参考：
下面是Insus.NET实现演示：
CObj.cs代码：
View Code using System; using System.Collections.Generic; using System.Linq; using System.Web; /// <summary> /// Summary description for CObj /// </summary> namespace Insus.NET { public class CObj { private int _Nbr; private int _Val; public int Nbr { get { return _Nbr; } set { _Nbr = value; } } public int Val { get { return _Val; } set { _Val = value; } } public CObj() { // // TODO: Add constructor logic here // } } }
GridView代码：
View Code < asp:GridView ID ="GridView1" runat ="server" AutoGenerateColumns ="false" Width ="230px" OnRowCreated ="GridView1_RowCreated" > < Columns > < asp:TemplateField > < HeaderTemplate > key </ HeaderTemplate > < ItemTemplate > <% # Eval ( " Nbr " ) %> </ ItemTemplate > </ asp:TemplateField > < asp:TemplateField > < HeaderTemplate > Value </ HeaderTemplate > < ItemTemplate > < asp:Label ID ="LabelVal" runat ="server" Text ='<%# Eval("Val") % >'> </ asp:Label > </ ItemTemplate > </ asp:TemplateField > < asp:TemplateField > < HeaderTemplate > operator </ HeaderTemplate > < ItemTemplate > < asp:Button ID ="ButtonAdd" runat ="server" Text ="+" /> < asp:Button ID ="ButtonSubtract" runat ="server" Text ="-" /> </ ItemTemplate > </ asp:TemplateField > </ Columns > </ asp:GridView >
引用 using Insus.NET;
xxx.aspx.cs代码：
View Code protected void Page_Load( object sender, EventArgs e) { if (!IsPostBack) { Data_Binding(); } } private void Data_Binding() { List<CObj> MyObj = new List<CObj>(); CObj o = new CObj(); o.Nbr = 1; o.Val = 100; MyObj.Add(o); this.GridView1.DataSource = MyObj; this.GridView1.DataBind(); } protected void GridView1_RowCreated( object sender, GridViewRowEventArgs e) { if (e.Row.RowType != DataControlRowType.DataRow) return; if (e.Row.FindControl( " ButtonAdd ") != null) { var ButtonAdd = e.Row.FindControl( " ButtonAdd ") as Button; ButtonAdd.Click += ButtonAdd_Click; } if (e.Row.FindControl( " ButtonSubtract ") != null) { var ButtonSubtract = e.Row.FindControl( " ButtonSubtract ") as Button; ButtonSubtract.Click += ButtonSubtract_Click; } } private void ButtonAdd_Click( object sender, EventArgs e) { var button = sender as Button; GridViewRow gvr = (GridViewRow)button.Parent.Parent; var Label = (Label) this.GridView1.Rows[gvr.RowIndex].FindControl( " LabelVal "); int v = Convert.ToInt32(Label.Text); Label.Text = (v + 1).ToString(); } private void ButtonSubtract_Click( object sender, EventArgs e) { var button = sender as Button; GridViewRow gvr = (GridViewRow)button.Parent.Parent; var Label = (Label) this.GridView1.Rows[gvr.RowIndex].FindControl( " LabelVal "); int v = Convert.ToInt32(Label.Text); Label.Text = (v - 1).ToString(); }
于 11：46分，Insus.NET添加二笔记录，分别测试每一行效果：
