RadGridView: KeyNotFoundException when copying cell value on filtered gridview with a single result

Steps to reproduce:

1. Please run the attached sample project

2. Filter grid so only one row is left

3.Copy the first cell with the content menu. The following error occurs:

************** Exception Text **************
System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.

Hello, Danny,

Thank you for reporting this. Currently, the possible solution that I can suggest is to set the SelectionMode property to CellSelect not at design time but at run time:

        public RadForm1()
        {
            InitializeComponent();

            radGridView1.EnableFiltering = true;
            radGridView1.ShowHeaderCellButtons = true;
            radGridView1.ShowFilteringRow = false;

            DataTable dt = new DataTable();
            dt.Columns.Add("Id", typeof(int));
            dt.Columns.Add("Description",typeof(string));
            for (int i = 0; i < 10; i++)
            {
                dt.Rows.Add(i,Guid.NewGuid().ToString());
            }
            radGridView1.DataSource = dt;

            this.radGridView1.MasterTemplate.SelectionMode = Telerik.WinControls.UI.GridViewSelectionMode.CellSelect;
        }

Please make sure that the property setting is commented in the Designer.cs file.
