<UrlAction Url="~remoteAppUrl/Pages/Default.aspx?{StandardTokens}&amp;SPListItemId={ItemId}&amp;SPListId={ListId}&amp;SPItemUrl={ItemUrl}" />

and its working fine, but when I am using

Microsoft.SharePoint.Client.UserCustomAction _customAction = web.UserCustomActions.Add();
_customAction.RegistrationType = UserCustomActionRegistrationType.ContentType;
_customAction.RegistrationId = _guidOfCreatedCT;
_customAction.Location = "EditControlBlock";
_customAction.Sequence = 450;
_customAction.Title = "TEST";
string rrr =AppRelativeVirtualPath.ToString();
_customAction.Url = "~remoteAppUrl/Pages/Default.aspx?{StandardTokens}&SPListItemId={ItemId}&SPListId={ListId}&SPItemUrl={ItemUrl}";
_customAction.Update();
clientContext.ExecuteQuery();

this url is not working. I dont know how to format this one, I tried everything and still any ideas. Someone can help me ?

Answer 1

You only need & to replace & in any XML structure, but you don't need to use & in the code behind...

Answer 2

Simply try using http:// or https:// in front of your custom url. Otherwise SharePoint will think that the action url is within SharePoint and so it will automatically generate a site relative url.
