C# windows程序中,如果实现DataGrid单行双击事件? C# Form中,如何让鼠标实现单行双击事件,而双击DataGrid头等地方不触发事件? 请给出程序示例,谢谢! 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 直接给你代码吧 namespace DataGridDoubleClick { using System; using System.Drawing; using System.Collections; using System.ComponentModel; using System.Windows.Forms; using System.Data; public class Form1 : System.Windows.Forms.Form { private System.Windows.Forms.DataGrid dataGrid1; private DataSet myDataSet; DateTime gridMouseDownTime; private System.Windows.Forms.Label label1; private System.ComponentModel.Container components = null; public Form1() { InitializeComponent(); gridMouseDownTime = DateTime.Now; SetUp(); } private void SetUp() { // 用2个Table和1和Relation创建DataSet MakeDataSet(); // 数据绑定 dataGrid1.SetDataBinding(myDataSet, "Customers"); //添加样式 AddCustomDataTableStyle(); } private void MakeDataSet() { // 创建DataSet. myDataSet = new DataSet("myDataSet"); // 创建2个DataTables.
