... This solution fails in a situation where searched node's grand parent is collapsed but its childrens are expanded. ...

Please check out the snippet of JS function below.

function FindNextNode()
{
    var tv = ISGetObject("WebTreeView1");
    var searchText = document.getElementById("txtSearch").value;
    if(searchText != "")
    {
        var node = tv.FindNextNodeByText(searchText);
        if (node != null)
        {                
            //node.Select();
            node.ExpandHierarchyAndSelect();
            node.GetElement().scrollIntoView();                
        }
        else
            alert("The search text can't be found");
    }
    else
        alert("Please fill in the search text");
}

I use this JS function to search WebTreeViewNode by text. ExpandHierarchyAndSelect() is called instead of invoking the Select() method. This method, ExpandHierarchyAndSelect(), will expands and selects nodes in a hierarchy.

After hierarchy is expanded and node get selected, invoke scrollIntoView() to scrolls the selected node element into the visible area of the browser window.

This should helps.

I created a simple sample of WebCombo with OnShowDropDown client-side event. Each time OnShowDropDown JS function is invoked, it will update dvLog div element and displays: "OnShowDropDown invoked".

OnShowDropDown client-side event of WebCombo specifies the client-side function to be invoked when the result box of a combo is being shown. It will be invoked when:

• DropDown arrow is clicked.
• Load more data arrow

I enclosed the sample as attachment. Could you please evaluate the sample on your end and let me know if the OnShowDropDown keep invoked until you close the application or not?

Sorry for the delay in sending this.

Here is what I created based on your scenario: JavaScript function is be used to create and show WebDesktopWindow. The WebDesktopWindow will load an image and use iFrame as its ContentMode. The snippet is as follow:

function AddWindow()
{
    var dm = ISGetDesktopManager();
    var wnd = dm.GetWindow("wndAboutDM");

    if (wnd == null)
    {
        wnd = new WebDesktopWindow();
        wnd.Name = "wndHTMLPage";
        wnd.ContentURL = "../Images/coverflow_images/timesquare.jpg";
        wnd.ContentMode = "UseIFrame";
        wnd.AllowMinimize = "No";
        wnd.AllowMaximize = "No";

        dm.Windows.Add(wnd);
        wnd.Show();
    }
    else
    {
        wnd.Activate();
    }
}

Next, in order to get the dimension of the image (ContentURL of WebDesktopWindow), the image will be appended to a dummy element.

function ResizeWebDesktopWindow(imgSrc, wnd)
{
    var element = document.getElementById("dummyElement");
    var elem = document.createElement("img");

    elem.src = imgSrc;
    elem.setAttribute("style", "visibility: collapse;");
    elem.addEventListener('load', function ()
    {
        var imgWidth = this.naturalWidth;
        var imgHeight = this.naturalHeight;
        wnd.ResizeTo(imgWidth, imgHeight);
               
    });

    element.appendChild(elem);
}

As you may see, the WebDesktopWindow is now resized based on the size of its content. In this simple case, is an image. Call ResizeWebDesktopWindow function after invoking Show() method, so the AddWindow() function will look like below after modified:

function AddWindow()
{
    var dm = ISGetDesktopManager();
    var wnd = dm.GetWindow("wndAboutDM");

    if (wnd == null)
    {
        wnd = new WebDesktopWindow();
        wnd.Text = "HTML Page";
        wnd.Name = "wndHTMLPage";
        wnd.ControlBoxImage = "is_webdesktop-16.gif";
        wnd.ContentURL = "../Images/coverflow_images/timesquare.jpg";
        wnd.ContentMode = "UseIFrame";
        wnd.AllowMinimize = "No";
        wnd.AllowMaximize = "No";
               
        dm.Windows.Add(wnd);
        wnd.Show();
        ResizeWebDesktopWindow("http://mywebsite/Images/coverflow_images/timesquare.jpg", wnd)
    }
    else
    {
        wnd.Activate();
    }

}

Hope this helps.

Hello Thomas,

Could you please perform the following and re-test the reported problem?

1. Close all Visual Studio and Xamarin Studio
2. Removes packages folder from the sample project.
3. Removes bin and obj folders from the Android and Core projects.
4. Connect the test device to development PC.
5. Uninstall the sample app using "adb uninstall" command. In this case: "adb uninstall MyInventory.Android.Material".
6. Using text editor software, manually update Crosslight NuGet package to Crosslight 5.0.5000.638.
7. Open sample project in Visual Studio or Xamarin Studio.
8. Restore NuGet packages.
9. Re-test the issue.

Look forward to hearing back from you.
