Please refer to the attached sample project and follow the steps illustrated on the attached gif file.

Workaround: subscribe to the CellBeginEdit event and focus the grid:

public partial class UserControl1 : UserControl
{
    public UserControl1()
    {
        InitializeComponent();
        this.radGridView1.CellBeginEdit += radGridView1_CellBeginEdit;

To reproduce:

1. Add a UserControl and drop a RadGridView in it.
2. Use the following code:

public partial class UserControl1 : UserControl
{
    public UserControl1()
    {
        InitializeComponent();
        ColumnGroupsViewDefinition view = new ColumnGroupsViewDefinition();
       
      this.radGridView1.ViewDefinition = view;
        
        view.ColumnGroups.Add(new GridViewColumnGroup("Group"));
        view.ColumnGroups[0].Rows.Add(new GridViewColumnGroupRow() );
        GridViewTextBoxColumn col = new GridViewTextBoxColumn("Col1");
        this.radGridView1.Columns.Add(col);
        view.ColumnGroups[0].Rows[0].ColumnNames.Add("Col1");           
    }
}

3. Drag the UserControl from the Toolbox to the form.

Workaround: set the ViewDefinition property after all columns are added.

The GridViewNewRowInfo is in modified state when the DefaultValuesNeeded event is used. This causes the UserAddingRow event to be fired.

Workaround: 
void radGridView1_DefaultValuesNeeded(object sender, GridViewRowEventArgs e)
{
    e.Row.Cells["SearchType"].Value = "BI";
 
    FieldInfo fieldInfo = typeof(GridViewRowInfo).GetField("state", BindingFlags.NonPublic | BindingFlags.Instance);
    BitVector32 state = (BitVector32)fieldInfo.GetValue(e.Row);
    state[2] = false;
    fieldInfo.SetValue(e.Row, state);
 
    e.Row.InvalidateRow();

If you refresh an object set property of entity context, the RadGridView is not updated. 

The sample code below does not work:

this.radGridView1.DataSource = entities.Countries;

int maxId = (from c in entities.Countries
                         orderby c.Id descending
                         select c.Id).First();

            Country country = new Country();
            country.Id = maxId + 1;
            country.Name = Path.GetRandomFileName();
            entities.Countries.AddObject(country);
            entities.SaveChanges(System.Data.Objects.SaveOptions.AcceptAllChangesAfterSave);

            entities.Refresh(System.Data.Objects.RefreshMode.StoreWins, entities.Countries);

Steps to reproduce:
1. Place a grid on a form and add several columns.
2. Set a ColumnGroupsViewDefinition to the grid and resize the columns so the horizontal scroll bar appears.
3. Add a button and on its click call the PrintPreview method of the grid.

You will see that the horizontal scroll bar of the grid will disappear.

Workaround:workaround it by increasing and decreasing the width of a single column with 1 pixel right after you call the Print method of the print document.

document.Print()
  grid.Columns(0).Width += 1
  grid.Columns(0).Width -= 1

To reproduce:
- Add CommandColumn to the grid
- Observe the size of the button in the newrow row

Workaround:
- Add some padding in the cell formating event

 void radGridView1_CellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)
        {
            GridViewNewRowInfo row = e.Row as GridViewNewRowInfo;
           
            GridCommandCellElement cell = e.CellElement as GridCommandCellElement;

            if (row != null && cell != null)
            {                
                cell.CommandButton.SetDefaultValueOverride(RadItem.MarginProperty, new System.Windows.Forms.Padding(0,0,1,0));
            }

1. Create a new project with RadGridView and setup hierarchy.
2. Run the project.
3. Select the "add new row" and click Escape key to leave edit mode.
4. Press Tab several times. You will see that the current cell is indistinguishable.

I have a form with a RadGridView that's bound to an list of Custom Objects. Each custom object has a property that is also a list of custom objects of a different class. I added a child template to the main grid for this property and created a relation between the two. Everything displays nicely and I can add new rows to the main grid. However, when I attempt to add a new row to one of the child grids, the row does not get added.
