flowlayout控制不斷增加在winforms中的錯誤方向的控制

Question

我有一個在winforms中的flowlayout控件，我已經設置其流向爲TopDown，但它始終從左到右添加控件，自動滾動也設置爲true。

flowLayoutPanel1.Controls.Clear();  
Label labelInput = new Label(); 
ListBox listBoxNewInput = new ListBox(); 

//Initialize label's property 
labelInput.Text = " #" + Convert.ToInt32(sequence); 
labelInput.AutoSize = true; 

//Initialize textBoxes Property 
listBoxNewInput.HorizontalScrollbar = false; 

listBoxNewInput.Items.Add(efforts); 
//Add the newly created text box to the list of input text boxes 
inputTextBoxesList.Add(listBoxNewInput); 

//Add the labels and text box to the form 
flowLayoutPanel1.FlowDirection = FlowDirection.TopDown; 
flowLayoutPanel1.Controls.Add(labelInput); 
flowLayoutPanel1.FlowDirection = FlowDirection.TopDown; 
flowLayoutPanel1.Controls.Add(listBoxNewInput); 

Answer 1

設置flowLayoutPanel1的WrapContents屬性false，它不會允許移動右側的控制，如果他們不適合。爲了能夠滾動剪輯的內容，你可以AutoScroll屬性設置爲true

下面是代碼：

flowLayoutPanel1.FlowDirection = FlowDirection.TopDown; 
flowLayoutPanel1.WrapContents = false; 
flowLayoutPanel1.AutoScroll = true; 
flowLayoutPanel1.Controls.Add(labelInput); 
flowLayoutPanel1.Controls.Add(listBoxNewInput);
