Winform控件重写

Winform控件重写

因为最近的项目中越来越多的遇到了比较特殊的一些控件，有时候我们自己封装一下可能更加方便我们的使用，下面是我们项目中用到的，简单做一个记录。

TextBox控件重写

主要的控制代码都在WndProc中

只能输入数字，包括小数

  public class FloatNumTextBox : TextBox
     {
         protected override void WndProc(ref Message m)
         {
             int WM_CHAR = 0x0102;
             if (m.Msg == WM_CHAR)
             {
                 if (((char)m.WParam >= '') && ((char)m.WParam <= '') ||
                 (int)m.WParam == (int)Keys.Back || (int)m.WParam == (int)Keys.Delete)
                 {
                     base.WndProc(ref m);
                 }
             }
             else
             {
                 base.WndProc(ref m);
             }
         }
     }

只能输入整数

 public class IntNumTextBox :TextBox
     {
         protected override void WndProc(ref Message m)
         {
             int WM_CHAR = 0x0102;
             if (m.Msg == WM_CHAR)
             {
                 if (((char)m.WParam >= '') && ((char)m.WParam <= '') ||
                 (int)m.WParam == (int)Keys.Back)
                 {
                     base.WndProc(ref m);
                 }
             }
             else
             {
                 base.WndProc(ref m);
             }
         }
     }

DataGridFView重写

DataGridView的主要代码是因为有很多的样式不需要再重新设置了，这样可以只修改一处，即可修改整个项目中的所有DataGridView样式的显示，主要的代码起始都是在构造函数中完成

  public class MydataGridview :DataGridView
     {
         public MydataGridview():base()
         {
             System.Windows.Forms.DataGridViewCellStyle dataGridViewCellStyle1 = new System.Windows.Forms.DataGridViewCellStyle();
             System.Windows.Forms.DataGridViewCellStyle dataGridViewCellStyle2 = new System.Windows.Forms.DataGridViewCellStyle();
             System.Windows.Forms.DataGridViewCellStyle dataGridViewCellStyle3 = new System.Windows.Forms.DataGridViewCellStyle();
             this.AutoGenerateColumns = false;
             this.AllowUserToAddRows = false;
             this.AllowUserToDeleteRows = false;
             this.AllowUserToResizeColumns = false;
             this.AllowUserToResizeRows = false;
             dataGridViewCellStyle1.BackColor = System.Drawing.Color.FromArgb(((int)(((byte)()))), ((int)(((byte)()))), ((int)(((byte)()))));
             this.AlternatingRowsDefaultCellStyle = dataGridViewCellStyle1;
             this.AutoSizeColumnsMode = System.Windows.Forms.DataGridViewAutoSizeColumnsMode.Fill;
             this.BackgroundColor = System.Drawing.Color.White;
             this.BorderStyle = System.Windows.Forms.BorderStyle.Fixed3D;
             this.ColumnHeadersBorderStyle = System.Windows.Forms.DataGridViewHeaderBorderStyle.Single;
             dataGridViewCellStyle2.Alignment = System.Windows.Forms.DataGridViewContentAlignment.MiddleCenter;
             dataGridViewCellStyle2.BackColor = System.Drawing.Color.FromArgb(((int)(((byte)()))), ((int)(((byte)()))), ((int)(((byte)()))));
             dataGridViewCellStyle2.Font = new System.Drawing.Font("宋体", 9F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)()));
             dataGridViewCellStyle2.ForeColor = System.Drawing.Color.Navy;
             dataGridViewCellStyle2.SelectionBackColor = System.Drawing.SystemColors.Highlight;
             dataGridViewCellStyle2.SelectionForeColor = System.Drawing.SystemColors.HighlightText;
             this.ColumnHeadersDefaultCellStyle = dataGridViewCellStyle2;
             this.ColumnHeadersHeight = ;
             this.ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.DisableResizing;
             dataGridViewCellStyle3.Alignment = System.Windows.Forms.DataGridViewContentAlignment.MiddleLeft;
             dataGridViewCellStyle3.BackColor = System.Drawing.SystemColors.Window;
             dataGridViewCellStyle3.Font = new System.Drawing.Font("宋体", 9F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)()));
             dataGridViewCellStyle3.ForeColor = System.Drawing.SystemColors.ControlText;
             dataGridViewCellStyle3.SelectionBackColor = System.Drawing.Color.FromArgb(((int)(((byte)()))), ((int)(((byte)()))), ((int)(((byte)()))));
             dataGridViewCellStyle3.SelectionForeColor = System.Drawing.SystemColors.ControlText;
             dataGridViewCellStyle3.WrapMode = System.Windows.Forms.DataGridViewTriState.False;
             this.DefaultCellStyle = dataGridViewCellStyle3;
             this.EnableHeadersVisualStyles = false;
             this.GridColor = System.Drawing.Color.FromArgb(((int)(((byte)()))), ((int)(((byte)()))), ((int)(((byte)()))));
             this.Location = new System.Drawing.Point(, );

             this.RowHeadersVisible = false;
             this.RowTemplate.Height = ;
             this.SelectionMode = System.Windows.Forms.DataGridViewSelectionMode.FullRowSelect;
             this.Size = new System.Drawing.Size(, );

         }
     }
