问题描述
大家好，最近开始学习asp.net，并且已经遇到了自己无法决定的问题.我需要创建一个GridView任意数字，该GridView从数据库输出信息并建议对其进行编辑(编辑"按钮).当我单击编辑"按钮时，代码崩溃，并显示错误"GridView" ctl02"触发了未处理的事件RowEditing."当我创建一个静态控件时，一切正常，但是我需要动态生成控件.
Hi all, recently started learning asp.net and already have a problem that can''t myself decide. I need to create arbitrary number a GridView which output information from DataBase and propose editing it ("edit" button). Code crashed when I click in button "edit" with that error "The GridView ''ctl02'' fired event RowEditing which wasn''t handled." When I create one static control everything is working fine, but I need dynamically generate controls.
public partial class _Default : System.Web.UI.Page
{
private SqlConnection Conn;
GridView Grid;
override protected void OnInit(EventArgs e)
{
Conn = new SqlConnection(
ConfigurationManager.ConnectionStrings["MyDBConnectionString"].ConnectionString
);
Conn.Open();
Grid = new GridView();
Grid.AutoGenerateColumns = false;
CommandField Command = new CommandField();
Command.ShowEditButton = true;
Grid.Columns.Add(Command);
BoundField Boundf = new BoundField();
Boundf.DataField = "FamilyName";
Grid.Columns.Add(Boundf);
SqlDataSource DataSource = new SqlDataSource(
ConfigurationManager.ConnectionStrings["MyDBConnectionString"].ConnectionString,
"SEL ECT FamilyName FR OM Samples");
Grid.DataSource = DataSource;
Grid.DataBind();
this.Form.Controls.Add(this.Grid);
}
protected void Page_Load(object sender, EventArgs e)
{
this.DataBind();
}
此代码可以正常工作
