    {
        RadPropertyStore vInfoStore = new RadPropertyStore();
        DataTable dt = Global.www.GetVirtualMachine(uid);
        PropertyStoreItem v_nm = new PropertyStoreItem(typeof(string), "Name", dt.Rows[0]["v_nm"],
                        "Name", "INFO");
        vInfoStore.Add(v_nm);
     
        return vInfoStore;
    }
     
    private void radListView1_SelectedIndexChanged(object sender, EventArgs e)
    {
                ListViewDataItem item = radListView1.SelectedItem;
                string uid = item["uid2"].ToString();

    Hello,

    Thanks for writing.

    This is a known issue of RadPropertyGrid which we will address in the upcoming release (Q2 2012). To work around it, you should modify your code as follows:
    private void radListView1_SelectedIndexChanged(object sender, EventArgs e)
    {
      ListViewDataItem item = radListView1.SelectedItem;
      string uid = item["uid2"].ToString();
      
      this.radPropertyGrid1.SelectedObject = null;
      this.radPropertyGrid1.SelectedObject = CreatePropertyStore(uid);
    }

    I hope this will help. If you need further assistance, I would be glad to provide it.

    Hi,

    Thank you for writing us back.

    Indeed, the provided code is not working properly when using our latest release - Q1 2012 SP1. As my colleague said, the issue will be addressed in our next release - Q2 2012. 

    You can solve the issue by adding a call to the ListSource.Clear method. Here is a sample:
    grid.SelectedObject = null;
    grid.PropertyGridElement.PropertyTableElement.ListSource.Clear();
    grid.SelectedObject = CreatePropertyStore("test");

    I hope this helps.
     
    All the best,
