• winform 制定DataGridViewTextColumn列(更改DataGridView的Cell的状态很有用)


    先自定义一个类 继承DataGridViewTextBoxCell

    using System;
    using System.Collections.Generic;
    using System.Text;
    using System.Windows.Forms;
    using System.Drawing;
    
    namespace com.Threes.CustomControl
    {
        public class DataGridViewBooleanCell : DataGridViewTextBoxCell
        {
            protected override void Paint(Graphics graphics, Rectangle clipBounds, Rectangle cellBounds, int rowIndex,
                DataGridViewElementStates cellState, object value, object formattedValue, string errorText,
            DataGridViewCellStyle cellStyle, DataGridViewAdvancedBorderStyle advancedBorderStyle, DataGridViewPaintParts paintParts)
            {
                // Call the base class method to paint the default cell appearance.
                base.Paint(graphics, clipBounds, cellBounds, rowIndex, cellState, value, "", errorText, cellStyle, advancedBorderStyle, paintParts);
                
                if (value is Boolean)
                    if ((bool)value == true)
                    {
                        graphics.DrawString("Y", cellStyle.Font, new SolidBrush(Color.Blue), cellBounds.X, cellBounds.Y);
                    }
                    else
                    {
                        graphics.DrawString("N", cellStyle.Font, new SolidBrush(Color.Red), cellBounds.X, cellBounds.Y);
                    }
                else if (value is int)
                {
                    int v = (int)value;
                    if (v == 1)
                    {
                        graphics.DrawString("", cellStyle.Font, new SolidBrush(Color.Blue), cellBounds.X, cellBounds.Y);
                    }
                    else if (v == 0)
                    {
                        graphics.DrawString("", cellStyle.Font, new SolidBrush(Color.Red), cellBounds.X, cellBounds.Y);
                    }
                    else
                    {
                        graphics.DrawString("人妖", cellStyle.Font, new SolidBrush(Color.Green), cellBounds.X, cellBounds.Y);
                    }
                }
            }
    
        }
    
    }

    再自定义一个类 继承DataGridViewColumn

    using System;
    using System.Collections.Generic;
    using System.Text;
    using System.Windows.Forms;
    
    namespace com.Threes.CustomControl
    {
        public class DataGridViewBooleanColumn : DataGridViewColumn
        {
            public DataGridViewBooleanColumn()
            {
                this.CellTemplate = new DataGridViewBooleanCell();
            }
        }
    }
