过滤LINQ导致ASP.NET Web窗体与分页

Question

我试图筛选GridView控件的内容，但是我在这个过程中得到一些关闭的行为：

的ASP页面样子的内容这样的：

<form id="form1" runat="server"> 

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> 
<asp:Button ID="button1" runat="server" onclick="button1_Click" Text="Submit" /> 
<asp:GridView ID="GridView1" AllowPaging="true" PageSize="8" 
AutoGenerateColumns="false" runat="server" 
OnPageIndexChanging="GridView1_PageIndexChanging"> 

<Columns> 
    <asp:BoundField HeaderText="ID" DataField="ID" /> 
    <asp:BoundField HeaderText="Client Name" DataField="Client_Name" /> 
    <asp:BoundField HeaderText="Project" DataField="Project_Name" /> 
    <asp:BoundField HeaderText="Uploaded By" DataField="Uploaded_By" /> 
</Columns> 

</asp:GridView> 
</form> 

而且隐藏文件中的代码：

public partial class Sample1 : System.Web.UI.Page 
{ 
    protected void Page_Load(object sender, EventArgs e) 
    { 
    if (!this.Page.IsPostBack) 
    { 
     SourceDataContext db = new SourceDataContext(); 

     GridView1.DataSource = from q in db.Cust 
           orderby q.ID 
           select q; 
     GridView1.DataBind(); 
    } 
} 

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) 
{ 
    GridView1.PageIndex = e.NewPageIndex; 
} 

protected void button1_Click(object sender, EventArgs e) 
{ 
    string client = TextBox1.Text; 

    SourceDataContext db = new SourceDataContext(); 

    GridView1.DataSource = from q in db.Cust 
          where q.Client_Name == client 
          orderby q.ID 
          select q; 
    GridView1.DataBind(); 

    //reset page index to 0 
    GridView1.PageIndex = 0; 
} 
} 

筛选部分作品，不过分页没有。此外，该分页需要该页面被点击两次以供选择。

谢谢。

试试吧。 保存此代码的功能让命名BindGrid

private void BindGrid() 
{ 
SourceDataContext db = new SourceDataContext(); 

    GridView1.DataSource = from q in db.Cust 
          orderby q.ID 
          select q; 
    GridView1.DataBind(); 
} 
// Create this method in your code behind 

和assinging新的索引到你的网格视图后assinging新的索引

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) 
{ 
    GridView1.PageIndex = e.NewPageIndex; 
    BindGrid(); 
}
