Question

我正在尝试搜索我的webgrid上的数据但是当我从下拉菜单中选择或键入textBox时，数据会消失。

我已关注此链接：http://www.mikesdotnetting.com/article/180/displaying-search-results-in-a-webgrid。

代码如下。请帮助。

@{
    Layout = "~/_SiteLayout.cshtml";
    Page.Title = "Payment Schedule";
    var db = Database.Open("GroupCashFlow");
    var query = "SELECT DISTINCT Company FROM PaymentSchedule ORDER BY Company";
    var companies = db.Query(query);
    query = "SELECT *  FROM dbo.PaymentSchedule where Account like @0 and Company like @1"; 
    var account = "%" + Request["account"] + "%";
    var company = "%" + Request["company"] + "%";
    var data = db.Query(query, account,company);
    var columns = new[]{"Date","Company","Account", "Payee","Section","Category","Product","Currency","Amount","FX","USD","Comments"};
    var grid = new WebGrid(data,columnNames: columns,rowsPerPage: 20);
}

修复 - 我改变了这一部分：

 account: <input type="text" name="company" value="@Request["account"]" />

要：

 account: <input type="text" name="account" value="@Request["account"]" />
