Hello Darren.

We have updated this Knowledge base article, since previously it works for first level pages only.

To achieve requested functionality, please do following (in <project folder>/CMSWebParts/General/languageselectionwithflags.ascx.cs file):

Under “foreach (DataRow dr in ds.Tables[0].Rows)” in SetupControl() method please add:

/////////
string YourDomainName = "http://www.mydomain.com/"; //Please change to requested domain name. Must be ended by slash "/"!
string YourHomePageAspxFileName = "default.aspx"; // This is default value, please do not change
/////////

Then please change this piece of code:
if (this.ShowCultureNames)
{
// original code
}
else
{
// original code
}

Like:

if (this.ShowCultureNames)
{
ltlHyperlinks.Text += "<a href=\"" + YourDomainName + YourHomePageAspxFileName + "?lang=" + dr["CultureCode"].ToString() + "\">";
ltlHyperlinks.Text += dr["CultureShortName"].ToString();

// Set surrounding div css class
selectionClass = "languageSelectionWithCultures";
}
else
{
ltlHyperlinks.Text += "<a href=\"" + YourDomainName + YourHomePageAspxFileName + "?lang=" + dr["CultureCode"].ToString() + "\">";

// Set surrounding div css class
selectionClass = "languageSelection";
}

Now it works for all pages.

Best Regards,
Radek Macalik
