C# Winform控件自适应窗体大小:方法1(推荐)

参考链接:https://www.cnblogs.com/PER10/p/11541568.html

需求:当窗体尺寸动态改变时,窗体中的各种控件(包括Panel以及Panel中的子控件)可以动态调节自身大小,以适应窗体内容比例。

 

方法:

 

第一步,新建一个类,代码如下:

class Resize     {         private Form _form;          public Resize(Form form)         {             int count = form.Controls.Count * 2 + 2;             float[] factor = new float[count];             int i = 0;             factor[i++] = form.Size.Width;             factor[i++] = form.Size.Height;             foreach (Control ctrl in form.Controls)             {                 factor[i++] = ctrl.Location.X / (float)form.Size.Width;                 factor[i++] = ctrl.Location.Y / (float)form.Size.Height;                 ctrl.Tag = ctrl.Size;             }             form.Tag = factor;             this._form = form;         }          public void Form1_Resize(object sender, EventArgs e)         {             float[] scale = (float[])this._form.Tag;             int i = 2;             foreach (Control ctrl in this._form.Controls) //panel的长宽增长到一个固定的值就不会再增长了,原因:Panel的宽和高上限是65535像素(https://blog.csdn.net/dufangfeilong/article/details/41805073?utm_source=blogxgwz5)             {                 ctrl.Left = (int)(this._form.Size.Width * scale[i++]);                 ctrl.Top = (int)(this._form.Size.Height * scale[i++]);                 ctrl.Width = (int)(this._form.Size.Width / (float)scale[0] * ((Size)ctrl.Tag).Width);                 ctrl.Height = (int)(this._form.Size.Height / (float)scale[1] * ((Size)ctrl.Tag).Height);             }         }     }     第二步,在Form的初始化函数中使用这个类:     public Form_StockCount()         {             InitializeComponent();               this.SizeChanged += new Resize(this).Form1_Resize;  //窗口自适应代码          } 

  

C# Winform窗体和控件自适应大小:方法2

1.在项目中创建类AutoSizeForm

                    c.Height = (int)(ctrHeight0 * hScale);//                     ctrlNo++;//累加序号                     //**放在这里,是先缩放控件本身,后缩放控件的子控件                     if (c.Controls.Count > 0)                         AutoScaleControl(c, wScale, hScale);//窗体内其余控件还可能嵌套控件(比如panel),要单独抽出,因为要递归调用                      if (ctl is DataGridView)                     {                         DataGridView dgv = ctl as DataGridView;                         Cursor.Current = Cursors.WaitCursor;                          int widths = 0;                         for (int i = 0; i < dgv.Columns.Count; i++)                         {                             dgv.AutoResizeColumn(i, DataGridViewAutoSizeColumnMode.AllCells);  // 自动调整列宽                               widths += dgv.Columns[i].Width;   // 计算调整列后单元列的宽度和                                                }                         if (widths >= ctl.Size.Width)  // 如果调整列的宽度大于设定列宽                               dgv.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.DisplayedCells;  // 调整列的模式 自动                           else                             dgv.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill;  // 如果小于 则填充                            Cursor.Current = Cursors.Default;                     }                 }               }         }     }     2.在要自适应大小的Form中自定义全局类对象  AutoResizeForm asc = new AutoResizeForm();  3.在要自适应大小的Form的load事件和SizeChange事件中执行对象方法  private void WidgetAutoResizeForm_Load(object sender, EventArgs e)         {             asc.controllInitializeSize(this);         }          private void WidgetAutoResizeForm_SizeChanged(object sender, EventArgs e)         {             asc.controlAutoSize(this);         }         From窗体代码:      using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms;  namespace CSharpFormApplication {     public partial class WidgetAutoResizeForm : Form     {         AutoResizeForm asc = new AutoResizeForm();         public WidgetAutoResizeForm()         {             InitializeComponent();         }          private void WidgetAutoResizeForm_Load(object sender, EventArgs e)         {             asc.controllInitializeSize(this);         }          private void WidgetAutoResizeForm_SizeChanged(object sender, EventArgs e)         {             asc.controlAutoSize(this);         }     } }    https://www.cnblogs.com/AmatVictorialCuram/p/5066670.html
