    Hi,

    It looks like our FeedViewPort class is not designed for using in user control.

    Well, you could apply the following change to FeedGrid.cs, then rebuild solution and re-test. But I'm not sure it will work.

    The FeedGrid.cs location is
    <SVN folder>\Ext.Net.Examples\Examples\Combination_Samp les\Applications\Feed_Viewer\Classes\UI\FeedGrid.c s

    Change to apply
    private void BuildStore()
{
    this.store = new Store
    {
        ID = "TopicStore",
        IDMode = IDMode.Explicit, //added
        AutoLoad = false,
        
        //here is the same code
    };

    this.Controls.Add(this.store);
}
    One change - the following code
    IDMode = IDMode.Explicit,
    is added.

    Hi,

    FeedViewPort is not designed for reusing.

    1. ViewPort cannot be placed inside another panel. You have to change ViewPort by panel or container
    2. If you place user control to ContentControls then wrap user control markup by FitLayout
    3. Move all store to inner Store collection of respective data controls (for example, grid.Store.Add(new Store{...})).
    4. Set IDMode="Static" for FeedViewPort
    5. FeedViewPort is not designed for rendering because all ids are rendered to js script class. When you rerender control ids will be different (if you did not define it explictly)

    So, the most easy way is using AutoLoad with IFrame mode and load the page with FeedViewPort to DesktopWindow
