Im new to Telerik, and this been bugging me for a while now.

Hope someone out there can help me.

Hi Joachim Karlsson,

I guess that RadGridView remains in edit mode. Could you please try to add additional "Save" column?

<telerik:GridViewColumn>
                        <telerik:GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <telerik:RadButton Content="Save" Command="telerikGrid:RadGridViewCommands.CommitEdit" />
                            </DataTemplate>
                        </telerik:GridViewColumn.CellTemplate>
                    </telerik:GridViewColumn>

After edit is complete click on a Save button, and let me know how it works.

All the best,
