Hi Roi,

I can replicate your issue here. However this problem appear because it has create the object at client side when showing for the first time. You could change the size value by changing its Window after it has the Window value. Here's the code:

function WebButton1_OnClientClick(controlId, parameter) {
    var WebDialogBox1 = ISGetObject("WebDialogBox1");
    if (WebDialogBox1.Window == null) {
        WebDialogBox1.Height = "200px";
        WebDialogBox1.Width = "400px";
    }
    else {
        WebDialogBox1.Window.ResizeTo("400px", "200px");
    }
    WebDialogBox1.ShowDialog();
    return true;
}

When initialize the Window attribute will be null so the height and width will refer to WebDialogBox' Height and Width and it will refer to window object when it has been initialized. Hope this helps.

Bernard Hi, 

Fantastic! Works like charm!

Though I think that should have been done automatically, just by calling ShowDialog(); 

BTW, where can I find full client side API's for all controls?

Hi Roi,

Yes, I think it should have done automatically just by using ShowDialog(). But I think there is some API that our user inherit from our WebDesktop that cause us to search a different level object for rendering different size on WebDialogBox. However, I will add you suggestion to our developer team so they can consider this scenario in the future. For your information, you can see all of our client side API reference on our Documentation in Client Side Reference section. Hope this helps.

Bernard
