Question

Pretty new to ASP.NET and trying to figure out how to have the code just echo the information it fetched.

<ul class="accordion">
    <% foreach (var cat in Model.Categories.Where(x=>x.ParentId==null).OrderBy(x=>x.DisplayOrder).ThenBy(x=>x.CategoryName)) { %>
        <li style="height: auto; min-height:30px;">
            <%= Html.ActionLink(cat.CategoryName, "Index", "Products", new { id=cat.UniqueName, area="" }, null)%>

            <%if(cat.SubCategories.Count>0) {%>
                <ul class="sub-menu" style="font-size:.8em; padding-left:20px;">
                    <% foreach (var c in cat.SubCategories) { %>
                        <li><%= Html.ActionLink(c.CategoryName, "Index", "Products", new { id=c.UniqueName, area="" }, null)%></li>
                    <% } %>
                </ul>
            <%}%>
        </li>
    <%} %>
</ul>

Currently I know it has to do with <%= Html.ActionLink(cat.CategoryName, "Index", "Products", new { id=cat.UniqueName, area="" }, null)%> that line but not sure how to make it pass the information. Might be a stupid question but Google definitely did not help when searching for this answer.

Thanks.

Answer 1

Here is a brief overview of some of the commands:

 <%= Html.ActionLink(cat.CategoryName, "Index", "Products", new { id=cat.UniqueName, area="" }, null)%>

Will create:

 <a href="products/index/{UniqueName}">{CategoryName}</a>

Which can also be constructued as:

 <a href="<%= Url.Action("Index", "Products", new { id=cat.UniqueName, area="" })%>"><%: cat.CategoryName%></a>

Which will also create:

 <a href="products/index/{UniqueName}">{CategoryName}</a>

So, you can output just the name or ID using:

 <%: cat.CategoryName %>

OR

 <%= cat.CategoryName %>

<%= is “Response.Write” and “<%:” Is Response.Write with HTML Encode
