To set the start location of FolderBrowserDialog in C# and VB.NET you can use the following snippet.
To do so, simply set the SelectedPath Value to the path you want.
MyFolderBrowserDialog.SelectedPath = @"C:\Test";
MyFolderBrowserDialog.SelectedPath = "C:\Test"
To get the current URL in jQuery you can use the following snippet.
$(location).attr('href');
To reload a page in Javascript you can use the location.reload method.
location.reload();
for more informations see Location reload() Method
To do a HTTP redirect using Javascript or jQuery you can use the window.location.href or the window.location.replace property.
window.location.replace("http://codesnippets.fesslersoft.de");
window.location.href = "http://codesnippets.fesslersoft.de";
you should use replace if you want to create a http redirect and href if you want to simulate a click.
You can also do this in jQuery but i personally prefer the methods shown above because there is no need to use jQuery for a http redirect.
var newUrl = "http://codesnippets.fesslersoft.de";
$(location).attr('href',newUrl);
