Problem with IsReadOnly and XamTextEditor
posted

 

I'm using the XamDataGrid to display notes for some projects in my application. For some users it shouldn't be possible to edit these notes. I therefore used FieldSettings to bind the IsReadOnly-property to a property in my ViewModel. The problem however, is, that the IsReadOnly-property only works on the XamComboEditor, and not the XamTextEditor.

 

XamComboEditor-field:

 

                    <igDP:Field Name="NoteType" Label="Type">

                        <igDP:Field.Settings>

                            <igDP:FieldSettings EditorType="{x:Type igEditors:XamComboEditor}">

                                <igDP:FieldSettings.EditorStyle>

                                    <Style TargetType="{x:Type igEditors:XamComboEditor}">

                                        <Setter Property="DataContext" Value="{Binding ElementName=layoutRoot, Path=DataContext}"/>

                                        <Setter Property="ItemsSource" Value="{Binding NoteTypes}" />

                                        <Setter Property="DisplayMemberPath" Value="Name" />

                                        <Setter Property="ValuePath" Value="NoteTypeId" />

                                        <Setter Property="IsReadOnly" Value="{Binding M.AccessReadOnly}" />

                                    </Style>

                                </igDP:FieldSettings.EditorStyle>

                            </igDP:FieldSettings>

                        </igDP:Field.Settings>

                    </igDP:Field>

 

 

XamTextEditor-field:

 

<igDP:Field Name="NoteText" Label="" Width="*">

                        <igDP:Field.Settings>

                            <igDP:FieldSettings EditorType="{x:Type igEditors:XamTextEditor}">

                                <igDP:FieldSettings.EditorStyle>

                                    <Style TargetType="{x:Type igEditors:XamTextEditor}">

                                        <Setter Property="IsReadOnly" Value="{Binding M.AccessReadOnly}" />

                                    </Style>

                                </igDP:FieldSettings.EditorStyle>

                            </igDP:FieldSettings>

                        </igDP:Field.Settings>

                    </igDP:Field>

The IsReadOnly-property works just fine if I set it to false in the XAML. But when I use databinding it doesn't...

    Hello Christian,

    Thank you for your post. I have been looking through it and the code you have provided and I suggest you change the Binding in the XamTextEditor to the following one:

    <Setter Property="IsReadOnly" Value="{Binding DataItem.M.AccessReadonly}" />

    Because the DataContext there is DataRecord. Please let me know if this helps you or you need further clarifications on this matter.

    Looking forward for your reply.
