Category Navigation & Expanding all nodes

Hi all,

Is there a way to configure/mod the left nav category control/code to ALWAYS expand to show sub categories?

Regards,

No not out of the box.  You will need write some custom code to complete this.  

A quick and dirty way is to use a asp.net treeview control.

Thanks,
Matthew

Thanks Matthew!

Customization it is then I guess...

I had to do something similar and found this post.  I was going to implement my own control and thought about our good old friend - recursion.  It's already being use in CreateChildMenu, but only to populate the selected Category.

Therefore, my simple solution was to modify the signature of CreateChildMenu to include a boolean parameter (at the end): true - bring back all Categories; false - brind back only the selected (clicked) Category and its children.  Note. I recommend you set the boolean parameter from a setting stored in the db.

Here's the solution:

Path: Modules
Control: CategoryNavigation.ascx
Code File: CategoryNavigation.ascx.cs

Methods changed:

CreateMenu

Modified CreateChildMenu call to include true\false setting, e.g. CreateChildMenu(breadCrumb, 0, currentCategory, true);

CreateChildMenu

Modified signature to:

protected void CreateChildMenu(CategoryCollection breadCrumb, int rootCategoryID, Category currentCategory, int level, bool showAllCategories)

Wrapped up 'for' loop:

                if (showAllCategories)
                {
                    // Show All Categories and their children
                    CreateChildMenu(breadCrumb, category.CategoryID, currentCategory, level,showAllCategories);
                }
                else
                {
                    // Show only Selected Category children
                    for (int i = 0; i <= breadCrumb.Count - 1; i++)
                        if (breadCrumb[i].CategoryID == category.CategoryID)
                            CreateChildMenu(breadCrumb, category.CategoryID, currentCategory, level, showAllCategories);
                }

That was an easy fix - too easy?  I hope it helps someone.

not woking for me i need more help if you can
thank you

Hi,

What is the problem/error that you are receiving? If you post a snippet of your code then that would help.

Cheers

Thanks webie, the code works for me. Thank you.

put the code the webie provided after the below code in file then it should work.

link.HyperLink.Text = Server.HtmlEncode(catName);
if (padding > 0)
  link.LiLeftMargin = padding.ToString();

Thanks again webie.

Thank you Webie for posting this.  I was able to add it to my code, tweak it a little and it worked just fine.

Thanks again, Steffany
