Thread: Entity Control nav

I am using the following line of code to list the categories and subcategories in my aspdnsf site.

Code:

<aspdnsf:EntityControl ID="ctrlEntityCategory" runat="server" Header="leftnav" EntityType="Category" MaxMenuSize="<%$ Tokens:AppConfigUSInt, MaxMenuSize %>" />

Does anyone know how I can limit the categories that show up in that list? I do not want one whole top-level category to ever show when the pages are loaded.

Limit based on what factor?

Currently, this will output the following:

Art
Projects

I want it to only show Art. It could be limited based on name or category ID. I just cannot find the sql query that pulls in the categories for this control.

In computer speak, how do you know you only want to show Art? Is it because it is the first entry? It starts with an A? Is less than 4 letters? I am looking up the code I used for filtering my categories, but if you just arbitrarily just want to show Art, why do you have the other category at all? You could just hide it or remove it.

I would like to limit based on SEName or CategoryID. CategoryID would probably be best. I have a ton more categories and just gave two as an example.

So you'd filter based on a query string then?

I have added the following to entitycontrol.cs so that I can do an if statement to show or hide categories based on what is passed.

Code:

private const string SHOW_CAT = "ShowCat"; // All = All Categories, Project = Projects, Cat = Categories no Projects

The code I modified is in ASPDNSFCore/ProductMappingLinkItem.vb. That file contains the logic by which items are selected from the database for presentation in the menu. I modified my code to limit to the 10 most populous manufacturers, but you can probably get information form the query string with little effort. Look at about line 460 in GetAllFirstLevel.

You could just use an XmlPackage to render these Categories, then you have complete control over what is displayed and what gets filtered.
