我有一個Search.aspx頁面文本框和按鈕。 postback是Results.aspx它有一個GridView。 Sql查詢的工作原理與QueryDesigner一樣。Click Event Event For Cross Page PostBack
理論上，僞搜索應該通過在文本框中輸入一個值並點擊按鈕來完成。當我輸入一個值並單擊時，Results.aspx頁面打開，但爲空。
在Search.aspx click事件無非是：
protected void Button2_Click(object sender, EventArgs e){}
此設置的確在Web項目的工作，但是，將無法在Web站點，這這是。看起來，點擊事件不起作用，因爲沒有將該值提交到Results.aspx頁面。我沒有找到可以正常工作的點擊事件。我將不勝感激任何幫助。
編輯：SQL查詢很複雜，但正如我所說的，它在查詢設計器中輸入值時工作正常。我確實爲.cs添加了「命名空間」作爲網站，而不是Web項目，通常沒有命名空間。

可以顯示一些代碼？任何錯誤等？ – christiandev
感謝您的努力。代碼在上面。我沒有收到任何錯誤消息，只是目標頁面上的空白頁面。具有或不具有「命名空間」的結果相同。 – user1830924
請顯示您的Search.aspx的完整標記。必須有一些更多的標記，否則它將不能像驗證一樣工作，或者你確定在Search.aspx中只使用了這麼多的標記？ –
