あなたは実際のコードを提供していないので、この他の質問に基づいて必要なことを達成する方法の例をまとめました.
もう 1 つの質問は、単純にサーバーのドライブ C にあるファイルを取得し、それらをグリッド内で作成時間の降順でグループ化します。リピーターのマークアップは次のとおりです。
<asp:HiddenField ID="dataGroups" runat="server" />
<asp:Repeater ID="rpt" runat="server" OnItemDataBound="rpt_RowDataBound" >
<ItemTemplate>
<!-- Bind to your specific properties i.e. Invoice #, file type, etc. -->
<table id="tableItem" runat="server">
<tr>
<td style="width: 200px;">
<asp:Label ID="lblName" runat="server" Text='<%#Eval("Name") %>'></asp:Label>
</td>
<td style="width: 200px;">
<asp:Label ID="lblDirName" runat="server" Text='<%#Eval("DirectoryName") %>'></asp:Label>
</td>
<td style="width: 200px;">
<asp:Label ID="lblCreationTime" runat="server" Text='<%#Eval("CreationTime") %>'></asp:Label>
</td>
<td style="50px">
<asp:Button ID="btnAction" runat="server" Text="Hit me" OnClick="btnAction_Click"/>
</td>
</tr>
</table>
</ItemTemplate>
</asp:Repeater>
OnRowDataBoundイベントのコード ビハインドは次のとおりです。それがあなたが使用するものであるため、C＃で書かれています：
private int month = -1;
private int year = -1;
protected void rpt_RowDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
//Binding to FileInfo objects.
//Since we are grouping by CreationTime we need to check if it's time to create a new "group"
//Is current month and year different from the value previously stored on the month and year variables?
if (month != (e.Item.DataItem as FileInfo).CreationTime.Month || year != (e.Item.DataItem as FileInfo).CreationTime.Year)
{
month = (e.Item.DataItem as FileInfo).CreationTime.Month;
year = (e.Item.DataItem as FileInfo).CreationTime.Year;
//append the current group to the hidden variable "dataGroups" which will tell us quickly how many groups we have in total
dataGroups.Value += (e.Item.DataItem as FileInfo).CreationTime.ToString("yyyMM") + ",";
}
//for every row; "stamp it" with this attribute since we'll use it on the client side with jQuery
(e.Item.FindControl("tableItem") as HtmlTable).Attributes.Add("data-group", (e.Item.DataItem as FileInfo).CreationTime.ToString("yyyMM"));
}
}
今度はクライアント側です。折りたたみ可能なパネルを作成するには、jQuery マジックを実行する必要があります。
<link href="css/flick/jquery-ui-1.8.22.custom.css" rel="stylesheet" type="text/css" />
<script src="js/jquery-1.7.2.min.js" type="text/javascript"></script>
<script src="js/jquery-ui-1.8.22.custom.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
//asp hidden element containing the list of groups separated by commas.
//Check code behind of RowDataBound to see where is this populated
var dataGroups = $('#<%=dataGroups.ClientID%>').val().split(',');
for (var i = 0; i < dataGroups.length; i++) {
//split() doesn't have an option to ignore empty strings so we'll just ignore it
if (dataGroups[i] != '') {
//select all table elements with the data-group value matching the
//current group we are iterating over and enclose them all
//inside a div; effectively creating a "group"
$('table').filter(function (inputs) {
return $(this).data('group') == dataGroups[i];
}).wrapAll("<div class='accordion'>");
}
}
var accordions = $('.accordion');
//now, for every div enclosing the groups, create a Handle that will work as the element that
//collapses or expands the group
$(accordions).wrapInner("<div>").prepend('<h3><a href="#">Handle</a></h3>');
//Now replace the word "Handle" above for the actual group number/name or what have you
for (var i = 0; i < accordions.length; i++) {
$(accordions[i]).find('h3 a').text("Group " + $(accordions[i]).find('table:first').data('group'));
}
//finally call jQuery.accordion to create the accordions on every group
$('.accordion').accordion({ collapsible: true, autoHeight: false });
});
</script>
さて、これらのコード行はこれを生成します:
