Unable to access controls inside RadPropertyGrid

[Georg]

In my code-behind for the following XAML fragment, I would like to do "MyTextBox.Focus()", but MyTextBox is not accessible. Is there a way I can access it?

 

    <Grid>
        <telerik:RadPropertyGrid Item="{Binding}"
                                 RenderMode="Flat"
                                 AutoGeneratePropertyDefinitions="False"
                                 DescriptionPanelVisibility="Collapsed"
                                 SearchBoxVisibility="Collapsed"
                                 SortAndGroupButtonsVisibility="Collapsed"
                                 FieldIndicatorVisibility="Collapsed"
                                 Loaded="RadPropertyGrid_Loaded"
                                 LabelColumnWidth="150">
            <telerik:RadPropertyGrid.PropertyDefinitions>
                <telerik:PropertyDefinition DisplayName="Text"
                                            GroupName="Text Properties"
                                            OrderIndex="0">
                    <telerik:PropertyDefinition.EditorTemplate>
                        <DataTemplate>
                            <TextBox x:Name="MyTextBox"
                                     TextWrapping="Wrap"
                                     AcceptsReturn="True"
                                     AcceptsTab="True"
                                     Height="60"
                                     VerticalContentAlignment="Top"
                                     Text="{Binding Text, UpdateSourceTrigger=PropertyChanged}"/>
                        </DataTemplate>
                    </telerik:PropertyDefinition.EditorTemplate>
                </telerik:PropertyDefinition>
            </telerik:RadPropertyGrid.PropertyDefinitions>
        </telerik:RadPropertyGrid>
    </Grid>

I no longer need this functionality, although I'm still curious about it.

Hello Georg,

There is no out-of-the-box approach for accessing the TextBox, as it is within a DataTemplate. A possible approach would be to traverse the visual tree as discussed in the Find a WPF element inside DataTemplate in code-behind StackOverflow thread. I would not, however, recommend using such an approach. I would also like to clarify, that this is not specific for the UI for WPF RadPropertyGrid, but for the usage of DataTemplates in the framework in general.

Which argument must be sent to the function FindVisualChild because when I send the propertydefinition it make an error that property definition is not visual

[Martin Ivanov]

Hello Ali,

The FindVisualChild method accepts a UI element. In this case, that is the RadPropertyGrid control. If you decide to use this approach (getting the DataTemplate element using code), I would recommend you to try the Telerik visual tree helper methods. You can read more about this in the UI for WPF help documentation.
