AllowEdit only at new Rows
posted

Hi,

i would like to customize a colum of my Grid. If i set AllowEdit in the FieldSettings the whole colum is ReadOnly. 

I would like to allow Edit for new Rows but not for existing ones. So i tried to trigger the EditModeStarting event for the colum but the Code doesn't execute.

Here is the Code for the Colum and its Resources:

                  <Style x:Key="FahrzeugartFieldStyle" TargetType="{x:Type igDE:XamComboEditor}">
                    <EventSetter Event="EditModeStarting" Handler="FZArtSelectedItemChanged"/>
                    <Setter Property="ValuePath" Value="FA_ID" />
                    <Setter Property="DisplayMemberPath" Value="FA_Bezeichnung" />
                    <Setter Property="ItemsSource" Value="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=src:BASE},Path=_CRM.FAHRZEUG_ART, Mode=OneWay}" />
                </Style>

 

                        <igDP:Field Name="FZ_FA_ID" Label="Fahrzeugart" Width="120">
                            <igDP:Field.Settings>
                                <igDP:FieldSettings EditorStyle="{StaticResource FahrzeugartFieldStyle}" />
                            </igDP:Field.Settings>
                        </igDP:Field>

Thank you for your support.

    Thank you for your support. The second answer worked fine for me. Here ist the Code I triggered my requierys with:

     

            private void dg_Fahrzeug_EditModeStarting(object sender, Infragistics.Windows.DataPresenter.Events.EditModeStartingEventArgs e)
            {
                    if(e.Cell.Field.Name == "FZ_FA_ID")
                    {
                        if (e.Cell.Record.IsAddRecord == false)
                        {
                            e.Cancel = true;
                        }
                    }
            }
