gridview中的" "问题解决,碰到这个问题是在从excel导入数据过来时碰到的,导了一堆的 比较麻烦;

方法一:
如果gridview的boundfield是固定的,只要把每个datafield的htmlencode属性设为"False"
方法二: 使用Replace函数 Strings.Replace(TableCell.Text, " ", "")

 方法三:
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)

 {  

  //// Get the currently selected row using the SelectedRow property.  
GridViewRow row = GridView1.SelectedRow;   
// Load data from selected row into textboxes 
if (row.Cells[1].Text.Trim() != " ")  

   {        txtEditCust_ID.Text = row.Cells[1].Text.Trim();    }
}

方法四: 循环检查
  //将 替换成空值         

    for (int i = 0; i < gdvList.Rows.Count; i++)     

        {

                for (int j = 0; j < gdvList.Rows[i].Cells.Count; j++)    

             {                  

   if (gdvList.Rows[i].Cells[j].Text == " ")        

             {                    

     gdvList.Rows[i].Cells[j].Text = "";                     }   

              }          

   }
