gridview控件使用的困惑，求解

错误原因：CS1061：’GridView的’不包含定义为’BottomPagerRow’，并没有扩展方法“BottomPagerRow可以找到接受的第一个参数类型的GridView’（是否缺少using指令或程序集引用？）你要做翻页效果 不用这么麻烦的 。

不能操作gridview里的控件

Button mybtn = gridview1.FindControl(“button1“) as Button;mybtn引用的就是gridview1中的button1了在每行绑定的时候都要找一次《asp:gridview OnItemDataBound=“rpter_itemDataBound“ ... /》protected void rpter_itemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e) {Button mybtn = gridview1.FindControl(“button1“) as Button;操作mybtn}

asp.net中gridview控件无法实现编辑功能！

我用这种方法实现修改功能 你可以参考一下 我感觉你的DATABIND用的好像不对protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { tianjia(); bind(); }} protected void grid1_PageIndexChanging(object sender, GridViewPageEventArgs e) { grid1.PageIndex = e.NewPageIndex; bind(); } protected void grid1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e) { this.grid1.EditIndex = -1; bind(); } protected void grid1_RowUpdating(object sender, GridViewUpdateEventArgs e) { string name = ((TextBox)this.grid1.Rows.Cells.Controls).Text.ToString(); deletetea(classesnumber); } public void updatetea( string name, string field,string price, string classes, string classesnumber) { SqlConnection cn = new SqlConnection(“Data Source=(local);database=TEA; Integrated Security = True“); SqlCommand cmd = new SqlCommand(“update tea set name=’“ + name + “’,field=’“ + field + “’,price=’“ +price + “’,classes=’“ +classes + “’,classesnumber=’“+ classesnumber+“’ where classesnumber=’“ +classesnumber+ “’“, cn); //无法实现数据更新 cn.Open(); cmd.ExecuteNonQuery(); cn.Close(); bind(); } public void deletetea(string classesnumber) { SqlConnection cn = new SqlConnection(“Data Source=(local);database=TEA; Integrated Security = True“); SqlCommand cmd = new SqlCommand(“delete from tea where classesnumber=’“ + classesnumber + “’“, cn); cn.Open(); cmd.ExecuteNonQuery(); cn.Close(); }protected void grid1_RowEditing(object sender, GridViewEditEventArgs e) { this.grid1.EditIndex = e.NewEditIndex; bind(); } protected void bind() { SqlConnection connection = new SqlConnection(“Data Source=(local);database=TEA; Integrated Security = True“); string sql = String.Format(“Select * From Tea“); connection.Open(); SqlDataAdapter adapter = new SqlDataAdapter(sql, connection); DataSet dataset = new DataSet(); adapter.Fill(dataset); grid1.DataSource = dataset.Tables; grid1.DataKeyNames = new string { “classesnumber“ }; grid1.DataBind(); connection.Close(); } public void tianjia() { BoundField a = new BoundField(); a.DataField = “name“; a.HeaderText = “姓名“; BoundField b = new BoundField(); b.DataField = “field“; b.HeaderText = “地域“; BoundField c = new BoundField(); c.DataField = “price“; c.HeaderText = “价格“; BoundField d = new BoundField(); d.DataField = “classes“; d.HeaderText = “级别“; BoundField e = new BoundField(); e.DataField = “classesnumber“; e.HeaderText = “编号“; CommandField f = new CommandField(); f.HeaderText = ““; f.ShowEditButton = true; grid1.Columns.Add(a); grid1.Columns.Add(b); grid1.Columns.Add(c); grid1.Columns.Add(d); grid1.Columns.Add(e); grid1.Columns.Add(f); }

asp.net2.0 关于gridview控件的使用

用模板《asp:TemplateField HeaderText=“内容“》《ItemTemplate》 《asp:Lable runat=“server“ ID=“lblContent“ 》《/asp:HyperLink》《/ItemTemplate》《/asp:TemplateField》然后在DataBounded实际中，判断内容字数，超过字数的用substring方法截取部分，然后加上...，没有超过的，全部显示，就不加...了。

GridView控件显示的问题

e.Row.Cells就是所谓的数据格子哈 从0开始萦引string bookCase = e.Row.Cells.Text.ToString();//获得书架编号 这个就代表你GridView中第16列的数据字段你点GridView 列 中不是有个 DataField项么 这里面填数据库中相应的字段哈 它不就在GridView中出现相应的列么 这时候你就想要哪列的数据就数就行了哈 不明白的可以再M我……
