将参数传递给C＃背后的代码

Question

We have looked and looked all over the internet but we were unable to find a solution. We have a linkbutton and we want to pass a parameter to the code behind. This is the code:

<% foreach (Academia.CourseEN curso in MyCourses) { %>
            <% string id = curso.Id.ToString(); %>
       <div class="col-xs-12 col-sm-5 col-md-5 col-lg-3">
          <div class="panel panel-warning">
            <div class="panel-heading"><%: curso.Title %></div>
            <div class="panel-body"><%: curso.Id %></div>
            <div class="panel-body"><%: curso.Description %></div>
            <div class="panel-body"><%: curso.Price %></div>
            <div class="panel-body"><%: curso.Category %></div>
            <div class="panel-body">
                <div class="col-md-offset-2 col-md-10">

                <asp:LinkButton ID="ENameLinkBtn" runat="server" Text="Button" CommandArgument='<%# Eval("id") %>' OnClick="DeleteCourse_Click" ></asp:LinkButton>

                </div>
            </div>
          </div>
        </div>
       <%} %>

The problem is that eval always returns an empty value, which is not the case as when we display the id it has a value. I post the code behind code as well:

LinkButton btn = (LinkButton)(sender);
string yourValue = btn.CommandArgument;
ErrorMessage.Text = yourValue;

I dont know what else to do or what else to try, anything would behighly appreciated. Thanks everyone.

You can create a javascript function DeleteCourse()

function DeleteCourse()
{
   var param = $("#ENameLinkBtn").val();
   $.ajax(
         url:"your web method",
         data: '"param":"' + param + '"'
         ....)
}

Then assign it to your button OnClick="DeleteCourse()"
