FileName Property

[David]

This seems like it would be a common issue but I have not been able to find a reference in either the documentation or forums. I have a class that I want to edit using the RadPropertyGrid and one of the public properties is a string that contains a file path. I want to use the OpenFileDialog (or equivalent) to edit this property. Any help would be appreciated...

Thanks

Hello,

 Please excuse us for the delayed answer. Basically, RadPropertyGrid does not have such default editor, but you can easily customize it. Here is an article that illustrates how to assign your own editors to the fields. I guess that you need some button which displays OpenFIleDialog when gets clicked. Please, do not hesitate to ask for additional assistance in case it is needed.

I've tried many property grids in my days, and most of them have this functionality. Why not implement it for Q2?

I should have replied a while ago. Turns out this is really easy using a template (I used a template selector since I had a number of other properties that I wanted custom editors for as well. The XAML is:

<Grid.Resources>
    <local:PropertyGridTemplateSelector x:Key="dataTemplateSelector">
        <local:PropertyGridTemplateSelector.FilenamePropertyTemplate>
            <DataTemplate>
                <Grid>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition/>
                        <ColumnDefinition Width="Auto"/>
                    </Grid.ColumnDefinitions>
                    <TextBox Text="{Binding FilePath}" Grid.Column="0"/>
                    <Button Content="..." Width="25" Height="25" Grid.Column="1" Click="SelectFileClick"/>
                </Grid>
            </DataTemplate>
        </local:PropertyGridTemplateSelector.FilenamePropertyTemplate>
        <!-- More templates here -->
    </local:PropertyGridTemplateSelector>
</Grid.Resources>

Obviously the SelectFileClick handler displays the OpenFileDialog...

Ah, thanks a lot!!

Do I have to specify a data template for all data types? Ideally, I would inherit Telerik's implementation and add support for certain Filename properties.

Hello Guys,

@David, Thank you for posting this sample code.
@Kristoffer, our current policy towards RadPropertyGrid is to make it easily customizable, so that clients can adapt it for their custom needs. We have default editors for the most common types and we implement such for the most popular feature request, but we have never had considerable demand for filename editor. We will consider it for the future releases, in case it gains popularity.
