Hi Angie,
thanks for your reply! :)
your given code example (that I already know) is JavaScript and it's the same like my code. To use this within Lightswitch (Client: Browser, Server: IIS) we have to use the Eval function. For this we put in into a one single line code to make it more
readable. But also the following full code doesn't work:
var csvContent='TestConent';var blob = new window.Blob([csvContent],{type: 'text/csv;charset=utf-8;'});window.navigator.msSaveOrOpenBlob(blob, 'Test.txt')
Using this within in the Eval function ...
Dispatchers.Main.BeginInvoke(Function()
HtmlPage.Window.Eval("var csvContent='TestConent';var blob = new window.Blob([csvContent],{type: 'text/csv;charset=utf-8;'});window.navigator.msSaveOrOpenBlob(blob, 'Test.txt')")
End Function)
... Ends with the same error.
What is the Problem?
Maybe there is another way to create and download a file within Lightswitch ....
Can you help?
