flowlayout控件不断在winform中以错误的方向添加控件

Question

我在winforms中有一个flowlayout控件，我已将其流向设置为TopDown，但它不断从左到右添加控件，autoscroll也设置为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

将 flowLayoutPanel1 的 WrapContents 属性设置为 false，如果这些控件不合适，则不允许将其移动到右侧。为了能够滚动剪辑的内容，您可以将 AutoScroll 属性设置为 true

以下是代码：

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