更新面板gridview asp.net C＃

Question

你能帮我吗 当我单击ID 1,2 ....时，从查询字符串中获取ID，然后在另一张表中的id_proba上显示那些来自查询字符串的ID相等的名称。 可以，告诉我。 现在我喜欢单击GridView1中的ID 1,2 ..以仅刷新gridview 2而不是所有页面。 需要gridview才能放入Ajax更新面板。 我将gridview2放在“更新”面板中，但不知道该用什么写代码？

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
    DataKeyNames="id" DataSourceID="SqlDataSource1" CellPadding="4"

Answer 1

要通过单击GridView1刷新更新面板，可以在GirdView1的链接中添加一个javascript onclick处理程序。
在此事件处理程序中，您可以通过调用__doPostBack刷新更新面板。 您可以使用jQuery将事件处理程序添加到网格中的所有标签，如下所示：

<script>
   $(function() {
         $("#<%=GridView1.ClientID%> a").bind('click', function() {
             refreshUpdatePanel();
          });
   });

  function refreshUpdatePanel()
  {
    __doPostBack('UpdatePanel1', '');
  }
</script>

Answer 2

如果您的网格不太大，请将它们放在同一更新面板中。
这样，你就不必编写任何代码来获得GridView2在点击更新GridView1 。

像这样：

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
       <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
            DataKeyNames="id" DataSourceID="SqlDataSource1" CellPadding="4" 
            ForeColor="#333333" GridLines="None" 
            onselectedindexchanged="GridView1_SelectedIndexChanged">
            <AlternatingRowStyle BackColor="White" />
            <Columns>
                <asp:CommandField ShowSelectButton="True" />
                <asp:BoundField DataField="name" HeaderText="name" SortExpression="name" />

                <asp:HyperLinkField 
          DataTextField="id" 
          DataTextFormatString=" {0}" 
          DataNavigateUrlFields="id" HeaderText="id"
          DataNavigateUrlFormatString="WebForm1.aspx?ID={0}"   />
            </Columns>
            <EditRowStyle BackColor="#2461BF" />
            <FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
            <HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
            <PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
            <RowStyle BackColor="#EFF3FB" />
            <SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
            <SortedAscendingCellStyle BackColor="#F5F7FB" />
            <SortedAscendingHeaderStyle BackColor="#6D95E1" />
            <SortedDescendingCellStyle BackColor="#E9EBEF" />
            <SortedDescendingHeaderStyle BackColor="#4870BE" />
        </asp:GridView>

        <br />
        <asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="False" 
            DataSourceID="SqlDataSource2">
            <Columns>
                <asp:BoundField DataField="id_proba" HeaderText="id_proba" 
                    SortExpression="id_proba" />
                <asp:BoundField DataField="name" HeaderText="name" SortExpression="name" />
            </Columns>
        </asp:GridView>
        <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
        <asp:SqlDataSource ID="SqlDataSource2" runat="server" 
            ConnectionString="<%$ ConnectionStrings:ProbaConnectionString %>" 
            SelectCommand="SELECT [id_proba], [name] FROM [proba3] WHERE ([id_proba] = @id_proba)">
            <SelectParameters>
                <asp:QueryStringParameter Name="id_proba" QueryStringField="ID" Type="Int32" />
            </SelectParameters>
        </asp:SqlDataSource>
    </ContentTemplate>
</asp:UpdatePanel>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:ProbaConnectionString %>" 
    DeleteCommand="DELETE FROM [Proba1] WHERE [id] = @id" 
    InsertCommand="INSERT INTO [Proba1] ([name]) VALUES (@name)" 
    SelectCommand="SELECT [name], [id] FROM [Proba1]" 
    UpdateCommand="UPDATE [Proba1] SET [name] = @name WHERE [id] = @id">
    <DeleteParameters>
        <asp:Parameter Name="id" Type="Int32" />
    </DeleteParameters>
    <InsertParameters>
        <asp:Parameter Name="name" Type="String" />
    </InsertParameters>
    <UpdateParameters>
        <asp:Parameter Name="name" Type="String" />
        <asp:Parameter Name="id" Type="Int32" />
    </UpdateParameters>
</asp:SqlDataSource>
