[英]Add Dynamic cotrol to aspx Page
I want to add checkbox in table heads dynamically,I have created their ids dynamically but how to print it on Aspx Page ??? 我想在表头中动态添加复选框,我已经动态创建了它们的ID,但是如何在Aspx页面上打印呢?
<table border="1">
<thead>
<%string j = " Check"; %>
<%for (int i = 0; i < 10;i++ )
{%>
<th style="padding:2px; width:500px;">Table Head<br /><br />
<%
CheckBox chk = new CheckBox();
chk.ID = i + j;
chk.Text = "I am "+ i+j;
%>
<%=chk %>
</th>
<%} %>
</thead>
</table>
<input type="checkbox" id='<%=i%>' name="allcheck">
Use ASP.NET Web Form, please use HTML tags more, not like this :) 使用ASP.NET Web窗体,请更多使用HTML标记,而不是这样:)
CheckBox chk = new CheckBox();
chk.ID = i + j;
chk.Text = "I am "+ i+j;
example: aspx page: 示例:aspx页面:
<input type="hidden" id="userid" value='<%=userid>'/>
<input type="checkbox" id='<%=i%>' name="allcheck" /> with for
js code with jquery: 带有jQuery的js代码:
function delete()
var id_array = new Array();
$('input[name="allcheck"]:checked').each(function () {
id_array.push($(this).attr('id'));
});
var idstr = id_array.join(',');
$.ajax({
method:"POST",
url: "services/delete",
data: {
userid: $("#userid").val(), ids: idstr
}
})
with ashx: 使用ashx:
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
context.Response.Cache.SetNoStore();
string userid = "";
string ids = "";
try
{
string userid = context.Request.QueryString["userid"];
string ids = context.Request.QueryString["ids"];
//then do your things
}
catch (Exception)
{
throw;
}
}
Hopefully it can help you to deal with your problem. 希望它可以帮助您解决问题。
Front end 前端
<body>
<form id="form1" runat="server">
<table>
<thead id="test" runat="server">
</thead>
</table>
</form>
</body>
Back end 后端
protected void Page_Load(object sender, EventArgs e)
{
CheckBox cb = new CheckBox();
cb.ID="****";
test.Controls.Add(cb);
}
If you are using ASPX page then use simply any control like GirdView
or DataList
or Repeater
. 如果您使用的是ASPX页面,则只需使用GirdView
或DataList
或Repeater
类的任何控件GirdView
。
In that you put your checkbox
, it will create dynamic ID Automatically
and you can easily find that control on your back end coding.. 在您的checkbox
,它将自动创建dynamic ID Automatically
并且您可以在后端编码中轻松找到该控件。
For example check below links. 例如,检查以下链接。
