錯誤在GridView控件

Question

發現控制我的GridView其對數據綁定我需要HID Image控件，所以我做了這個代碼，但錯誤apear（rowIndex位置的網格視圖dosenot containe認定中），當我試圖找到控制

C＃代碼：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) 
    { 
     Img = GridView1.Rows[e.RowIndex].FindControl("Logo") as Image ; 

     using (SqlConnection con = Connection.GetConnection()) 
     { 
      string Sql = "Select Logo From Model where Id=@Id"; 
      SqlCommand com = new SqlCommand(Sql, con); 
      com.Parameters.Add(Parameter.NewInt("@Id", DDLModel.SelectedValue)); 
      com.CommandType = CommandType.Text; 
      SqlDataReader dr = com.ExecuteReader(); 
      if (dr.Read()) 
      { 
       string Img2 = dr["Logo"].ToString(); 
       if (Img2 == System.DBNull.Value.ToString()) 
       { 
        Img.Visible = false; 
       } 
      } 
     } 
    }

GridViewRowEventArgs包含行，所以你可以嘗試：

image = e.Row.FindControl("Logo") as Image;
