摘要:UpdatePanel 匯出到 Excel 按鈕的問題
一般用匯出的按鈕 放在UpdatePanel 會出現這樣的錯誤
但是 只要在UpdatePanel 設定一下 把按鈕 設定成postback 就可以了
我匯出xls的程式
01 
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
02
Response.Clear()
03 Response.AddHeader("content-disposition", "attachment;filename=1.xls")
04 Response.Charset = "utf-8"
05 Response.ContentType = "application/vnd.ms-excel" 'xls"
06 Dim stringWrite As System.IO.StringWriter = New System.IO.StringWriter
07 Dim htmlWrite As System.Web.UI.HtmlTextWriter = New HtmlTextWriter(stringWrite)
08 Dim strstyle As String
09 Me.GridView1.RenderControl(htmlWrite) strstyle = "<style>.xlString { mso-number-format:Text; } </style>"
10 Response.Write(strstyle)
11 Response.Write(stringWrite.ToString)
12 Response.End()
