大家好我有一個grid view其中我使用AJAX update panel。我將從Database的項目綁定到網格視圖，以便當用戶點擊Download這是可用我想要download該文件並提示用戶保存或取消。我寫的所有，當我用了更新面板，我能夠提示該文件，但與更新面板相同的代碼沒有給我我所需要的輸出運行它相關的代碼..無法輸出文件，當我點擊下載網格視圖
我的設計

這是我在Row command事件
if (e.CommandName == "DOWNLOAD")
{
StringBuilder sb = new StringBuilder();
String strConnString = System.Configuration.ConfigurationSettings.AppSettings.Get("ConnectionString");
string FileName = string.Empty;
FileName = "venkat.txt";
string strPath1 = Server.MapPath("AchTemplates") + "\\" + "venkat.txt";
int id1 = 0;
//string strLine = string.Empty;
// string[] lines = null;
MySqlConnection cnn = new MySqlConnection(strConnString);
cnn.Open();
GridViewRow row = (GridViewRow)((Control)e.CommandSource).Parent.Parent;
//Label l = (Label)grdACH.Rows[row.RowIndex].Cells[1].FindControl("Label1");
//Label l = (Label)grdACH.Rows[row.RowIndex].Cells[1].FindControl("lblid");
//strid = ((Label)grdACH.Rows[row.RowIndex].FindControl("lblid")).Text.ToString();
//id = Convert.ToInt16(l.Text);
string strid = ((Label)GridView1.Rows[row.RowIndex].FindControl("Label1")).Text.ToString();
id1 = Convert.ToInt16(strid);
string selectSQL = "Select File_Data from tblachmaster where ID IN (" + id1 + ")";
MySqlCommand cmd2 = new MySqlCommand(selectSQL, cnn);
// cmd1.Parameters.Add("@_id", SqlDbType.Int).Value = id;
//DataTable dt1 = GetData1(cmd1);
DataSet oDataSet = new DataSet();
MySqlDataAdapter oAdapter = new MySqlDataAdapter();
// oCmd.Parameters.AddWithValue("_FedTaxID", FedTaxID);
oAdapter.SelectCommand = cmd2;
oAdapter.Fill(oDataSet);
DataTable dt1 = oDataSet.Tables[0];
//string[] readText = File.ReadAllLines(strPath);
if (dt1 != null)
{
for (int i = 0; i < dt1.Rows.Count; i++)
{
Byte[] bytes = (Byte[])dt1.Rows[i]["File_Data"];
string text = Encoding.UTF8.GetString(bytes);
//lines = Regex.Split(text, "\r\n");
// sb.Append(lines.ToString());
sb.Append(text.ToString());
// strLine = convertArrayToString(lines);
}
}
File.WriteAllText(strPath1, sb.ToString());
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment;filename=genACH(CCD).txt");
Response.Charset = "";
Response.ContentType = "application/text";
Response.Output.Write(strPath1);
Response.Flush();
Response.End();
}
代碼，但我不能解僱一個我需要的任何一個可以幫助我
您將無法使用UpdatePanel與下載請求一起使用，如果您通過回發到服務器來下載文件。 UpdatePanel會搞砸了...... –
那麼我怎麼能達到這個按我的要求 – Dotnet
刪除UpdatePanel，或添加觸發器只回應某些事件 –
