編寫搜索功能的一點點體會

還是之前的系統（說是說項目管理系統，不過說是計劃管理系統可能更容易理解吧，呵呵），需要有查詢功能。要做查詢，最主要是用戶需要查哪些信息，再寫SQL語句啦，不然就要做無用啦。

還有一點要注意麼，就是能用列表表示出來的，就儘量用列表表示出來，儘量減少用戶的輸入量，呵呵。

又來貼代碼了，嘻嘻

查詢頁面asp頁面，查詢條件--狀態、級別、分類、負責人都是用dropdownlist控件直接綁定數據庫的信息（像這些信息，基本都是一樣的，在系統中也是要多次用到，最好就用一個參數表把信息存在數據庫中）

實現根據關鍵字/關鍵字+列表（or的關係，選中列表的信息都會顯示出來）/列表（同樣的，也是or的關係）/全部信息（沒有輸入，也沒有選擇列表項）

.cs代碼：

public void bind() { //級別dropdownlist綁定數據 string sqlProMngLev = "select * from tbProMngPara where ParaName='級別'"; SqlDataAdapter daProMngLev = new SqlDataAdapter(sqlProMngLev, con); DataSet dsProMngLev = new DataSet(); con.Open(); daProMngLev.Fill(dsProMngLev); DdlProLevel.DataSource = dsProMngLev; DdlProLevel.DataTextField = "ParaDtl"; DdlProLevel.DataValueField = "ParaId"; DdlProLevel.DataBind(); DdlProLevel.Items.Insert(0, "請選擇");//添加“請選擇一項” con.Close(); //分類dropdownlist綁定數據 string sqlProMngSort = "select * from tbProMngPara where ParaName='分類'"; SqlDataAdapter daProMngSort = new SqlDataAdapter(sqlProMngSort, con); DataSet dsProMngSort = new DataSet(); con.Open(); daProMngSort.Fill(dsProMngSort); DdlProSort.DataSource = dsProMngSort; DdlProSort.DataTextField = "ParaDtl"; DdlProSort.DataValueField = "ParaId"; DdlProSort.DataBind(); DdlProSort.Items.Insert(0, "請選擇"); con.Close(); //狀態dropdownlist綁定數據 string sqlProMngSt = "select * from tbProMngPara where ParaName='狀態'"; SqlDataAdapter daProMngSt = new SqlDataAdapter(sqlProMngSt, con); DataSet dsProMngSt = new DataSet(); con.Open(); daProMngSt.Fill(dsProMngSt); DdlProState.DataSource = dsProMngSt; DdlProState.DataTextField = "ParaDtl"; DdlProState.DataValueField = "ParaId"; DdlProState.DataBind(); DdlProState.Items.Insert(0, "請選擇"); con.Close(); //負責人dropdownlist綁定數據 string sqlProMngDirector = "select * from tbProMngPara where ParaName='負責人'"; SqlDataAdapter daProMngDirector = new SqlDataAdapter(sqlProMngDirector, con); DataSet dsProMngDirector = new DataSet(); con.Open(); daProMngDirector.Fill(dsProMngDirector); DdlProDirector.DataSource = dsProMngDirector; DdlProDirector.DataTextField = "ParaDtl"; DdlProDirector.DataValueField = "ParaId"; DdlProDirector.DataBind(); DdlProDirector.Items.Insert(0, "請選擇"); con.Close();

查詢結果顯示在另一個頁面中，顯示每一個項目下的信息，若沒有查找到，就會顯示提示信息。
