如何更新以前的gridview行onrowdatabound

Question

如果sVal包含當前行的「字段名稱」，我需要更新上一行的單元格4以添加按鈕單擊事件。

protected void gv_RowDataBound(object sender, GridViewRowEventArgs e) 
{ 
    if (e.Row.RowType == DataControlRowType.DataRow) 
    { 
     string sVal = e.Row.Cells[2].Text; 
     if (sVal.Contains("Field Name")) 
     { 
      // update cell[4] of previous row with button click event 

      e.Row.Cells[2].BackColor = System.Drawing.Color.WhiteSmoke; 
      e.Row.Cells[2].Font.Bold = true; 

      e.Row.Cells[3].BackColor = System.Drawing.Color.WhiteSmoke; 
      e.Row.Cells[3].Font.Bold = true; 

      e.Row.Cells[4].BackColor = System.Drawing.Color.WhiteSmoke; 
      e.Row.Cells[4].Font.Bold = true; 

     } 
    }

    if (sVal.Contains("Field Name")) 
    {

     e.Row.Cells[2].BackColor = System.Drawing.Color.WhiteSmoke; 
     e.Row.Cells[2].Font.Bold = true; 

     e.Row.Cells[3].BackColor = System.Drawing.Color.WhiteSmoke; 
     e.Row.Cells[3].Font.Bold = true; 

     e.Row.Cells[4].BackColor = System.Drawing.Color.WhiteSmoke; 
     e.Row.Cells[4].Font.Bold = true;
