Question

我如何在运行时从其他表单的fragmentlayoutpanel中添加新按钮

   private void btnNotEkle_Click(object sender, EventArgs e)
    {
        YeniForm yeniForm = new YeniForm();
        Button btn = new Button();
        yeniForm.Controls.Add(btn);
    }

按钮不以JPYi形式存在。我应该在公共场所公开fraglayoutpanel吗？

Answer 1

使flawLayoutPanel成为public会暴露出实施细节，这是一种不好的做法。我建议将Button创建代码移至YeniForm中：

    public partial class YeniForm : Form {
      ...
      // Let's generalize the implementation and allow to create a control, 
      // not neccesary button
      public T CreateFlawControl<T>() where T : Control, new() {
        T result = new T() {
          Parent = flawLayoutPanel,  
        };

        //TODO : set Size, Location etc here

        return result; 
      }
    }

您可以将其用作

    private void btnNotEkle_Click(object sender, EventArgs e) {
       YeniForm yeniForm = new YeniForm();
       Button btn = yeniForm.CreateFlawControl<Button>();
       ... 
       // do not forget to show the form - yeniForm.Show() or yeniForm.ShowDialog()
    }

您可以在YeniForm中创建用于添加按钮/控件的方法，并以以下形式实现添加：

class YeniForm : Form
{
    ...
    public void AddButton(Button btn)
    {
        this.flowLayoutPanel1.Controls.Add(btn); // or whatever you need. Calc position for new control, add it to some kind of container (Panel/TableLayoutPanel etc)
    }
}

private void btnNotEkle_Click(object sender, EventArgs e)
{
    YeniForm yeniForm = new YeniForm();
    Button btn = new Button();
    yeniForm.AddButton(btn);
    ...
}
