Sharepoint Taxonomy Control in sandbox solution in sharepoint 2013

Question

Hi,
We have requirement  to bind termsets into taxonomy control  using sandbox solution in sharepoint 2013.
I cannot use webpart,and APP. Below code added in aspx page in module.
i cannot write any code as this sandbox solution.
<%@ Register Tagprefix="TaxonomyField" Namespace="Microsoft.SharePoint.Taxonomy" Assembly="Microsoft.SharePoint.Taxonomy, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c"
%>
 <TaxonomyField:TaxonomyWebTaggingControl ID="TWC" runat="server"  SspId="08d413ac-c81d-4232-b1df-c2da46f9b21a" TermSetId="06c93fa1-8a76-4637-9b87-5e612276c199"  AllowFillIn="true" IsMulti="false"
IsDisplayPickerButton="true"  Language="1033"  IsAddTerms="true" >
    </TaxonomyField:TaxonomyWebTaggingControl>
This is able to render the control, where as termsets are not being  displayed.
Please help on this.

I don't think hard coding SSPID and TermsetID is a good practice. Try to get the values through code and using unique names.
<Taxonomy:TaxonomyWebTaggingControl ID="TWC" IsDisplayPickerButton="true"
AllowFillIn="true" runat="server"
ShowTaxonomy(TWC, TaxonomyGroup, TermSetName);
public static void ShowTaxonomy(TaxonomyWebTaggingControl control, string taxonomyGroup, string termsetName)
SPContext context = SPContext.Current;
SPSite site = context.Site;
TaxonomySession tsession = new TaxonomySession(site);
TermStore ttermStore = tsession.TermStores["TermStore"];
Group tgroup = ttermStore.Groups[taxonomyGroup];
TermSet productsTermSet = tgroup.TermSets[termsetName];
control.SspId.Add(ttermStore.Id);
control.TermSetId.Add(productsTermSet.Id);
control.IsAddTerms = false;
control.AllowFillIn = false;
control.IsMulti = true;
control.IsIncludeUnavailable = false;
control.Language = 0;
if(termsetName==Constants.UserKeywordsTermSet)
control.AllowFillIn = true;
control.IsAddTerms = true;
