DevExpress XtraGrid 行雙擊事件的處理

要響應GridView的單擊或者雙擊事件，要設置GridView的OptionsBehavior.Editable＝false。如果為true,它是不會響應這這兩個事件的。 它本的的機制就是這樣，祥細說明請看： The   DoubleClick   event   occurs   when   the   end   user   double-clicks   within   a   view.   The   DoubleClick   event   does   not   occur   if   an   in-place   editor   is   activated   as   a   result   of   double-clicking   as   well   as   when   double-clicking   within   the   GridControl.EmbeddedNavigator.

 

       //雙擊行彈出nodeDetail信息 
        private void gridView1_MouseDown(object sender, MouseEventArgs e) 
        {  
            DevExpress.XtraGrid.Views.Grid.ViewInfo.GridHitInfo hInfo = gridView1.CalcHitInfo(new Point(e.X,e.Y));  
            if (e.Button == MouseButtons.Left && e.Clicks == 2) 
            {  
                //判斷光標是否在行范圍內  
                if (hInfo.InRow)  
                {  
                    //取得選定行信息  
                    string nodeName = gridView1.GetRowCellValue(gridView1.FocusedRowHandle, "nodeName").ToString(); 
                    //string nodeName = gridView1.GetRowCellValue(gridView1.GetSelectedRows()[0], "nodeName").ToString(); 
                    string sql = "select nodeDetail from treelist where nodeName = '" + nodeName + "'"; 
                    SqlCommand comm = new SqlCommand(sql, conn);  
                    try 
                    {  
                        conn.Open();  
                        MessageBox.Show(comm.ExecuteScalar().ToString(), "Detail"); 
                    }  
                    catch (Exception ex)  
                    {  
                        MessageBox.Show(ex.Message, "Error"); 
                    }  
                    finally 
                    {  
                        conn.Close();  
                    }  
                }  
            }  
        }
