HtmlPanel, How to scroll down programatically?

The quick answer is that you should try:
var scrollableElement = document.getElementById('scrollableElement');
scrollableElement.scrollIntoView();

In more detail:

1.Create a html file. Make sure that an element within it has the id set to “scrollableElement”. (or whatever id you want to use, doesn’t matter really)
2. In the Wisej designer, create a HtmlPanel from the toolbox. Set the HtmlSource to your HTML file.
3. In the Wisej designer, create a button from the toolbox. Add a Click event.
4. In the code for the Wisej page, you should have this:
public Page1()
{
InitializeComponent();
//When the htmlPanel is initialized, create a javascript function named Scroll.
htmlPanel1.InitScript = @"this.Scroll = function() {
var scrollableElement = document.getElementById('scrollableElement');
scrollableElement.scrollIntoView(); }";
}


private void button1_Click(object sender, EventArgs e)
{
//call the Scroll function
htmlPanel1.Call("Scroll");
}

The htmlPanel will scroll when the button is clicked.

I’ve attached a sample. Hope this helps!
