Issue with newrow and tab

[Thomas]

Hi,

When I do the following actions:
1. Add a new row 
2. Start to edit a cell
3. Start to tab to the next cell
then I get the following error message:

Hi,

I've tried this using our latest binaries (Q3 SP2) however the grid worked fine - please check the attached application. Can you verify if you have our latest service pack?

Sincerely yours,

Hi,
:
I build the project with the following configuration
telerik: 2009.3.1322.35
.net 4.0 beta 2

The gridview looks as follows:

  <rad:RadGridView Grid.Row="0"
                            Name="GridView1"
                            AutoGenerateColumns="False"
                            ValidationMode="Row"
                            ShowGroupPanel="False"
                            ColumnsWidthMode="Fill"
                            AddingNewDataItem="GridView1_AddingNewDataItem"
                            RowEditEnded="GridView1_RowEditEnded"
                            RowValidating="GridView1_RowValidating"
                            ShowInsertRow="True"
                            CanUserDeleteRows="True"
                            CanUserInsertRows="{Binding hasPermission, ElementName=root}"
                            ActionOnLostFocus="CommitEdit" MaxHeight="500" Width="400">
                    <rad:RadGridView.Columns>
                        <rad:GridViewDataColumn Header="Naam"
                                                DataMemberBinding="{Binding Naam}"
                                                IsReadOnly="{Binding hasNoPermission, ElementName=root}" />
                        <rad:GridViewDataColumn Header="Sommeerbaar"
                                                DataMemberBinding="{Binding IsSommeerBaar}"
                                                IsReadOnly="{Binding hasNoPermission, ElementName=root}" />

                    </rad:RadGridView.Columns>
                </rad:RadGridView>

Hello Thomas,

In your snippet I saw a hook for the RadGridView.AddingNewDataItem event, so I guessed that you are using a collection that does not implement INotifyPropertyChanged interface as RadGridView.ItemsSource. I've managed to reproduce just the same exception with the described scenario. This issue is already fixed and will be available with today's latest internal build. Please give it a try and let me know how it works on your side.

P.S. I've updated your Telerik points according to your report.

Kind regards,
