1個窗體上的多個DataGridViews

Question

我有一個顯示DataGridView的簡單窗體;我想在同一個表單的第一個下面顯示第二個DataGridView對象。

但是當我運行代碼時，它只顯示第一個。當通過調試器運行時，表單列出它有兩個datagridviews鏈接到它。

System.Windows.Forms.Form form 
      = new System.Windows.Forms.Form(); 
     form.Size = new System.Drawing.Size(450, 400); 
     form.Text = "Form"; 

     DataGridView dg = new DataGridView(); 
     dg.AllowUserToAddRows = false; 
     dg.AllowUserToDeleteRows = false; 
     dg.AllowUserToOrderColumns = true; 
     dg.Dock = System.Windows.Forms.DockStyle.Fill; 
     dg.Location = new System.Drawing.Point(0, 0); 
     dg.ReadOnly = true; 
     dg.TabIndex = 0; 
     dg.DataSource = dt; 
     dg.Parent = form; 



     DataGridView dgHangers = new DataGridView(); 
     dgHangers.AllowUserToAddRows = false; 
     dgHangers.AllowUserToDeleteRows = false; 
     dgHangers.AllowUserToOrderColumns = true; 
     dgHangers.Dock = System.Windows.Forms.DockStyle.Fill; 
// attempting get the bottom of the first DataGridView() so the second will display below. 
     dgHangers.Location = new System.Drawing.Point(0, dg.DisplayRectangle.Bottom); 
     dgHangers.ReadOnly = true; 
     dgHangers.TabIndex = 1; 
     dgHangers.DataSource = hangerTable; 
     dgHangers.Parent = form; 



     form.ShowDialog(); 

形式：

Answer 1

第一：與System.Windows.Forms.DockStyle.Fill;你無法看到同時創建DataGrid後， 因此，測試沒有這行你的兩個的dataGridView。

或者你可以使用第一：dg.Dock = System.Windows.Forms.DockStyle.Top;

和第二：dg.Dock = System.Windows.Forms.DockStyle.Bottom;

alsoo您可以使用form.Controls.Add(dg);代替dg.Parent = form;
