如何在C＃中调整窗体的大小以包含其控件？

Question

I am new to C# and I am using windows forms.

As shown in screenshot I have Form1 which has flowLayoutPanel1 and ButtonCancel .

When Form1 loads, number of buttons are added into the flowLayoutPanel1 (the number of buttons is changing and it is not fixed).

 private void Form1_Load(object sender, EventArgs e)
    {
        for (int i = 0; i <= 1; i++)
            {

            Button btn = new Button();
            btn.Name = i.ToString();  
            btn.Width = 104;
            btn.Height = 63;
            btn.FlatStyle = FlatStyle.Popup;              
            flowLayoutPanel1.Controls.Add(btn);

            }
 }

Problem:

The problem is that there is a gap that I want to remove, to do that I have to reduce Form1 Height according to the number of the added buttons but I do not know how to resize Form1 Height based on the number of added buttons .

For example, if 2 buttons are added I want Form1 to shrink to fit the 2 buttons and if 8 buttons are added I want Form1 to expand to fit the 8 buttons without leaving gap.

Is there any Form property allows Form1 to expand and shrink according to the number of added buttons ?

Thank you

Answer 1

The following should work

• Put a TableLayoutPanel with one column and two rows on the Form
• Set the Dock -property of the TableLayoutPanel to Fill
• Set the Size-Type of the first row of the TableLayoutPanel to Percent -> 100%
• Set the Size-Type of the second row of the TableLayoutPanel to Absolute -> 63 Pixel
• Put the FlowLayoutPanel inside the first row
• Put the Cancel- Button inside the second row
• Set the AutoSize -property of Form , TableLayoutPanel and FlowLayoutPanel to True
• Set the AutoSizeMode -property of Form , TableLayoutPanel and FlowLayoutPanel to GrowAndShrink
