按钮单击事件后 DataTable 不渲染 Gridview

问题描述

在创建页面时，一切正常，但是当我单击按钮以显示所选行时，我的网格视图不会呈现为数据表.我需要做什么来解决这个问题或我做错了什么?

In my page when it's creating, everything is working fine but when I am clicking on the button to show the selected row, then my grid view is not rendering as a datatable. What I need to do to fix this or what I am doing wrong?

我的脚本:

<script type="text/javascript">
        $(function () {
            $('[id*=gvTest]').prepend($("<thead></thead>").append($(this).find("tr:first"))).DataTable({
                "responsive": true,
                "sPaginationType": "full_numbers",
                
                 
            });
        });
        $(document).ready(function () {

            var table = $('#gvTest').DataTable();
            $('#gvTest tbody').on( 'click', 'tr', function () {
            $(this).toggleClass('selected');
            });
              
      
            $('#btnRead').click(function () {
           var ids = $.map(table.rows('.selected').data(), function (item) {
               return item[0]
                 });               
            });
           
    } );
    </script>

我的网格:

<asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager>
   <asp:UpdatePanel ID="updatePanel" runat="server">
     <ContentTemplate>

     <asp:GridView  ID="gvTest" Width="100%" runat="server"  AutoGenerateColumns="False" >
      <Columns>
           <asp:BoundField  DataField="PatientID"  HeaderText="Patient ID" >
           </asp:BoundField>
           <asp:BoundField  DataField="PatientName"  HeaderText="PatientName" >
           </asp:BoundField>
           <asp:BoundField  DataField="Age"  HeaderText="Age" >
           </asp:BoundField>
           <asp:BoundField  HeaderText="Sex" DataField="Sex"  >
           </asp:BoundField>
           <asp:BoundField  HeaderText="Mod" DataField="Modality"  >                                 
      </Columns>
    </asp:GridView>
</ContentTemplate>
</asp:UpdatePanel>

当我的页面被创建时:

一切正常，但是当我点击一个按钮时，就会发生这种情况:

Everything is working fine, but when I click a button then this happens:

推荐答案

在使用了很多其他代码后，我没有得到合适的解决方案，所以我在页面加载时使用了它，它工作正常

after using a lots of others code i did'nt get a proper solution so i used this on my page load and its working fine

gvTest.UseAccessibleHeader = true;
//adds <thead> and <tbody> elements
gvTest.HeaderRow.TableSection =
TableRowSection.TableHeader;
