写在c的datagridview中的行标题＃

Question

你能告诉我如何将行号写入c＃中的datagridview的行标题，就像在Excel中一样。
谢谢。

Answer 1

你可以试试这个;

void Gridview1_RowDataBound(Object sender, GridViewRowEventArgs e) 
    { 
    e.Row.Header = (e.Row.GetIndex()).ToString(); 
    } 

编辑：为Gridview首先代码，DataGridView

using System; 
using System.Collections.Generic; 
using System.Text; 
using System.Windows.Forms; 
using System.Drawing; 

namespace DataGridView2 
{ 

    class DataGridView2 : DataGridView 
    { 

     protected override void OnRowPostPaint(DataGridViewRowPostPaintEventArgs e) 
     { 
      base.OnRowPostPaint(e); 

      // get the row number in leading zero format, 
      // where the width of the number = the width of the maximum number 
      int RowNumWidth = this.RowCount.ToString().Length; 
      StringBuilder RowNumber = new StringBuilder(RowNumWidth); 
      RowNumber.Append(e.RowIndex + 1); 
      while (RowNumber.Length < RowNumWidth) 
       RowNumber.Insert(0, "0"); 

      // get the size of the row number string 
      SizeF Sz = e.Graphics.MeasureString(RowNumber.ToString(), this.Font); 

      // adjust the width of the column that contains the row header cells 
      if (this.RowHeadersWidth < (int)(Sz.Width + 20)) 
       this.RowHeadersWidth = (int)(Sz.Width + 20); 

      // draw the row number 
      e.Graphics.DrawString(
       RowNumber.ToString(), 
       this.Font, 
       SystemBrushes.ControlText, 
       e.RowBounds.Location.X + 15, 
       e.RowBounds.Location.Y + ((e.RowBounds.Height - Sz.Height)/2)); 
     } 
    } 
}
