Hi

I'm having a small problem with your excellent ItemViewer control..

I am adding a bunch of FileItems in code, but they all appear on top of each other until something happens to the control: e.g. I have a splitter bar between a TreeView and  ItemViewer and when I nudge that, the entries in the ItemView arrange themselves correctly.

Is there something I should be doing to force that on the initial load?

It's pretty straight forward:

   ivSources.Items.Clear();

            foreach (RSMainService.MetaSource s in list) {

                Liquid.FileItem item = new Liquid.FileItem();

                item.Text = s.sourceName;

                item.Tag = s;

                item.Name = s.accountName + "_" + s.sourceName;

                item.Icon = @"images/big_doc.png";

                ivSources.Items.Add(item);

            }

Thanks

Hi,

This a strange bug, you could try calling UpdateLayout() as this usually forces Silverlight to arrange its child elements.

Thanks!

I have the same problem.  I tried with UpdateLayout(), it does not work.

I see RenderSize and DesiredSize properties are having a value of (0, 0), but the ones I added through XAML are having (174, 54).  

Any workaround?

Thanks!

I had the same problem but a found the solution, do not use ivSources.Items

Here for your case :

ivSources.Clear();

foreach (RSMainService.MetaSource s in list)

{

        ivSources.Add(new Liquid.FileItem()

        {

                Text = s.sourceName,

                Tag = s,

                Name = s.accountName + "_" + s.sourceName,

                Icon = @"images/big_doc.png"

        });

}

And for better perfomance you can create a List at first

ivSources.Clear();

var lst = new List<Liquid.ItemViewerItem>();

foreach (RSMainService.MetaSource s in list)

{

        lst.Add(new Liquid.FileItem()

        {

                Text = s.sourceName,

                Tag = s,

                Name = s.accountName + "_" + s.sourceName,

                Icon = @"images/big_doc.png"

        });

}

ivSources.Add(lst);
