我一直在寻找解决方案以在模式上显示gridview。 gridview正确显示,没有错误,问题在于它的参数。我意识到gridview是运行任何javascript之前的进程。但是我需要它在单击模式按钮时显示。此按钮将数据更改为模态,并且应更改sqldatasource的参数,这也会更改gridview内容。
这是我的JavaScript
$(document).ready(function () {
$('#exampleModal').on('show.bs.modal', function (event) {
var button = $(event.relatedTarget) //Button that triggered the modal
var ckpt = button.data('whatever')
var clss = button.data('dtclass')
var modal = $(this)
modal.find('.modal-title').text(clss)
modal.find('.modal-title2').text(ckpt)
document.getElementById('ContentPlaceHolder1_lblckpt').innerText = clss;
})})
这是客户代码
<td><button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-dtclass="I010" data-whatever="Diameter">Go!</button></td>
<td><button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-dtclass="I030" data-whatever="Thickness">Go!</button></td>
这是我使用gridview的模式
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog modal-lg" role="document">
<div class="modal-content">
<div class="modal-header">
<p id="exampleModalLabel" style="font-size:22px;">Checkpoint :<asp:Label ID="txtckpt1" runat="server" class="form-control-label modal-title" style="font-size:22px;"></asp:Label> ~ <label id="txtckpt2" runat="server" class="form-control-label modal-title2" style="font-size:22px;"></label></p>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<div class="form-group">
<label for="txtequi" class="form-control-label">Equipment</label>
<table>
<tr>
<td colspan="2">
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" BorderStyle="Solid" BorderWidth="1px" ShowHeaderWhenEmpty="true"

<SelectParameters>
<asp:ControlParameter DefaultValue="" ControlID="lblckpt" Name="lblckpt" PropertyName="Text" Type="String" />
</SelectParameters>
</asp:SqlDataSource>
</td>
</tr>
</table>
</div>
<div class="form-group">
<label for="txtckpt" class="form-control-label">LI Class</label>

如您所见,模态打开后(使用javascript),我将值设置为 lblckpt 标签。然后将sqldatasource参数链接到 lblckpt ,以便可以显示gridview数据。我的项目中没有错误,此外,我尝试对参数进行硬编码,并且该参数可以正常工作。请给我建议或解决方案。

如果有人有使用gridview的解决方案,请告诉我。现在,我找到了使用AJAX aspx的解决方案。这是我正在使用的代码。我喜欢它,因为它具有更好的性能,而且无需刷新整个页面就可以获取实时数据。
以下是javascript
function AddTableEqui(clss){
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function () {
document.getElementById("div1").innerHTML = xhr.responseText;
}
xhr.open("GET", "GetEqui.aspx?clss=" + clss, true);
xhr.send(null);
}
然后,我在GetEqui.aspx中编码我的表,并使用 response.write()
返回所有html标记。
