HierarchicalTaxonField Control - Sitefinity - Front- & Back-End Development

Hello-

I'm using a HierarchicalTaxonField on a page and am trying to set the selected value for the control. I've tried via JavaScript and code behind without any success.

Here is the control definition on my page:

<sitefinity:HierarchicalTaxonField

ID="HierarchicalFieldControl"

runat="server"

DisplayMode="Write"

Expanded="true"

ExpandText="ClickToAddCategories"

ShowDoneSelectingButton="true"

AllowMultipleSelection="false"

TaxonomyId="E5CD6D69-1543-427b-AD62-688A99F5E7D4"

BindOnServer="true"

TaxonomyMetafieldName="Category"

WebServiceUrl="~/Sitefinity/Services/Taxonomies/HierarchicalTaxon.svc" />

Then via C# I've tried setting the value like this:

HierarchicalFieldControl.Value = categoryId;

That did not work, so I also tried setting it via JavaScript. The function is executed through Sys.Application.add_load, and the code to invoke the action looks like this:

hierarchicalFieldControl = $get('<%= HierarchicalFieldControl.ClientID%>');

hierarchicalFieldControl.control.set_value(categoryId.value);

And unfortunately that did not work either, but it did produce the following error:

"Guid should contain 32 digits with 4 dashes"

Which happened when the control attempted to perform a service call. I checked both instances of code to confirm the categoryId values were proper GUIDs and the were both formatted like this:

d8743bac-8dde-45e3-b51b-bc61ed5e0631

Any insight or suggestions would be appreciated.

Thanks,

-Thomas

Hello Thomas Weidman,

When BindOnServer is true the Value of this field is cast to TrackedList<Guid>, which in turn inherits from IList<T>, ICollection<T>, etc., so all you need to do is create a new instance of this class and add the GUIDs of the selected taxonomies to it.

I've run into this problem myself and still haven't found a solution. Setting the Value to a TrackedList of Guids does nothing.
