如何在使用LinqDataSource過濾（動態）之後刷新GridView？

Question

<asp:GridView ID="GridView2" runat="server" AllowPaging="True" 
    AllowSorting="True" AutoGenerateColumns="False" DataSourceID="LinqDataSource1"> 
    <Columns> 
     <asp:BoundField DataField="UserName" HeaderText="User Name" ReadOnly="True" 
      SortExpression="UserName" /> 
     <asp:BoundField DataField="FullName" HeaderText="Full Name" ReadOnly="True" 
      SortExpression="FullName" /> 
     <asp:BoundField DataField="Email" HeaderText="Email" ReadOnly="True" 
      SortExpression="Email" /> 
     <asp:BoundField DataField="LastLoginDate" HeaderText="Last Login" ReadOnly="True" 
      SortExpression="LastLoginDate" DataFormatString="{0:dd MMMM yyyy}"/> 
     <asp:HyperLinkField Text="Edit" DataNavigateUrlFields="UserId" DataNavigateUrlFormatString="~/Pages/UsersMaintenance/CreateEditUser.aspx?UserId={0}" /> 
    </Columns> 
</asp:GridView> 

<asp:LinqDataSource ID="LinqDataSource1" runat="server" ContextTypeName="MyDataContextDataContext" onselecting="LinqDataSource_Selecting"> 
     <WhereParameters> 
      <asp:Parameter Name="Subject" /> 
     </WhereParameters> 
</asp:LinqDataSource> 

public void LinqDataSource1_Selecting(object sender, LinqDataSourceSelectEventArgs e) 
     { 
       this.LinqDataSource1.WhereParameters["Subject"].DefaultValue = this.txtSubject.Text; 
       e.Result = reporterRepo.GetInquiries(); 

Answer 1

我的GridView控件在UpdatePanel的這就是爲什麼它不刷新gridview的

<asp:UpdatePanel.... 

Answer 2

請嘗試使用此功能，或者修改該功能，直到它有效。如果我是正確的我之前做過這樣的事：

public void LinqDataSource1_Selecting(object sender, LinqDataSourceSelectEventArgs e) 
{ 
    this.LinqDataSource1.WhereParameters["Subject"].DefaultValue = this.txtSubject.Text; 
    GridView2.DataBind(); 
    e.Cancel = true; 
}
