排序/寻呼

Question

（这是另一个问题，因为我的原帖，我在一个问题中提出了太多问题）

让我先说明一下。我对ASP编码几乎全新。我正在研究一个需要我使用ASP而不是PHP的小方案项目。我一直在寻找过去2天的解决方案，并尝试了很多东西，但似乎无法使用我的代码。我已经成为这个网站的一部分，所以我知道它是如何工作的。我不会在这里询问我是否已经有一段时间没有尝试过这样做了。我在这里学到了大量有关SQL的信息，所以我希望对ASP也这样做。

问题：

排序/寻呼

我知道我需要OnPageIndexChanging="GridView1_PageIndexChanging" OnSorting="GridView1_Sorting"和Code Behind使其适用于我的设置，否则我得到：“GridView'GridView1'触发事件排序，但未处理。”错误。我找到的任何解决方案，我都无法在我的代码中运行。

GridView1：

<asp:TextBox ID="TextBox1" runat="server" Width="265px" Height="22px" CssClass="myBox"></asp:TextBox>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Search Fields" CssClass="myButton" />
<asp:GridView ID="GridView1" OnPageIndexChanging="GridView1_PageIndexChanging" OnSorting="GridView1_Sorting" runat="server" AutoGenerateColumns="true" CellPadding="4" EnableModelValidation="True" EnableTheming="True" ForeColor="#333333" GridLines="None" Width="100%" style="margin-top: 0px; text-align: center;" AllowPaging="True" AllowSorting="True" >
    <AlternatingRowStyle BackColor="White" ForeColor="#284775" />
    <EditRowStyle BackColor="#999999" />
    <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
    <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
    <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
    <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
    <SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
</asp:GridView>

Code Behind（DB名称和密码取出）：

SqlConnection vid = new SqlConnection("Data Source=ENF;Initial Catalog=***Database Name***;Persist Security Info=True;User ID=sa;Password=***Password***");
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
    {
        GridView1.DataSource = GetData();
        GridView1.DataBind();
    }
}

protected void Button1_Click(object sender, EventArgs e)
{
    String str = "SELECT ab.NAME as [Customer] ,ISNULL(ab.TELEPHONE1,'') as [Phone #] ,ISNULL(pb.NAME,'') as [Product] ,ISNULL(aeb.NEW_PRODUCTVERSION,'') as [Version] ,CASE WHEN ab.STATUSCODE = 1 THEN 'Active' ELSE 'Inactive' END as [Status] ,ISNULL('Sal : ' + c.SALUTATION + ' / ','') + ISNULL('Title : ' + c.JOBTITLE + ' / ','') + ISNULL(a.PRIMARYCONTACTIDNAME,'') as [Primary Contact] ,ISNULL(c.TELEPHONE1,'') as [Contact Phone] FROM ACCOUNTBASE ab LEFT JOIN ACCOUNTEXTENSIONBASE aeb on ab.ACCOUNTID = aeb.ACCOUNTID LEFT JOIN PRODUCTBASE pb on aeb.NEW_PRIMARYPRODUCTID = pb.PRODUCTID LEFT JOIN ACCOUNT a on ab.ACCOUNTID = a.ACCOUNTID LEFT JOIN CONTACT c on a.PRIMARYCONTACTID = c.CONTACTID WHERE ((ab.NAME LIKE '%' + @search + '%') OR (aeb.NEW_PRODUCTVERSION LIKE '%' + @search + '%') OR (pb.NAME LIKE '%' + @search + '%') OR (a.PRIMARYCONTACTIDNAME LIKE '%' + @search + '%')) ORDER BY ab.NAME";
    SqlCommand xp = new SqlCommand(str, vid);
    xp.Parameters.Add("@search", SqlDbType.NVarChar).Value = TextBox1.Text;

    vid.Open();
    xp.ExecuteNonQuery();
    SqlDataAdapter da = new SqlDataAdapter();
    da.SelectCommand = xp;
    DataSet ds = new DataSet();
    da.Fill(ds, "Name");
    GridView1.DataSource = ds;
    GridView1.DataBind();

    vid.Close();
}

其他GetData（）

private DataSet GetData()
{
    String str = "SELECT ab.NAME as [Customer] ,ISNULL(ab.TELEPHONE1,'') as [Phone #] ,ISNULL(pb.NAME,'') as [Product] ,ISNULL(aeb.NEW_PRODUCTVERSION,'') as [Version] ,CASE WHEN ab.STATUSCODE = 1 THEN 'Active' ELSE 'Inactive' END as [Status] ,ISNULL('Sal : ' + c.SALUTATION + ' / ','') + ISNULL('Title : ' + c.JOBTITLE + ' / ','') + ISNULL(a.PRIMARYCONTACTIDNAME,'') as [Primary Contact] ,ISNULL(c.TELEPHONE1,'') as [Contact Phone] FROM ACCOUNTBASE ab LEFT JOIN ACCOUNTEXTENSIONBASE aeb on ab.ACCOUNTID = aeb.ACCOUNTID LEFT JOIN PRODUCTBASE pb on aeb.NEW_PRIMARYPRODUCTID = pb.PRODUCTID LEFT JOIN ACCOUNT a on ab.ACCOUNTID = a.ACCOUNTID LEFT JOIN CONTACT c on a.PRIMARYCONTACTID = c.CONTACTID WHERE ((ab.NAME LIKE '%' + @search + '%') OR (aeb.NEW_PRODUCTVERSION LIKE '%' + @search + '%') OR (pb.NAME LIKE '%' + @search + '%') OR (a.PRIMARYCONTACTIDNAME LIKE '%' + @search + '%')) ORDER BY ab.NAME";
    SqlCommand xp = new SqlCommand(str, vid);
    xp.Parameters.Add("@search", SqlDbType.NVarChar).Value = TextBox1.Text;

    vid.Open();
    xp.ExecuteNonQuery();
    SqlDataAdapter da = new SqlDataAdapter();
    da.SelectCommand = xp;
    DataSet ds = new DataSet();
    da.Fill(ds, "Name");
    vid.Close();

    return ds;
}

将此添加到Code Behind：

protected void GridView1_PageIndexChanging(object sender, EventArgs e)

{ }

protected void GridView1_Sorting（object sender，GridViewSortEventArgs e） { }

现在，当点击列名称或分页页面时，它只是闪烁页面，没有任何反应。

Answer 1

您必须实施Sorting事件

<asp:GridView OnSorting="GridView1_Sorting" />

protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)
{ 
    //sort the data
}

Answer 2

在我将以下行添加到页面aspx.cs文件后，错误消失了：

protected void GridView1_PageIndexChanging(object sender, EventArgs e)
 {
 }

 protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)
 {
 }

在GridView上进行分页/排序
