pyRevit WPF Form for Asking user for Multiple Paths

If you ever wanted to ask your users for multiple paths, you can use this custom WPF form.

EF-WPF Form

Here is the overview of the form that I will give you the code for.

It's simple, but yet very elegant to collect multiple paths. But also you can extend the functionality if you know how to work with WPF.

Happy Coding!

Folderstructure

To create WPF forms you need to create .xaml file and then use it inside of your python script.

Let's break them down one by one.

.XAML Script

Xaml - is the file format for WPF forms, which is used for designing front-end of the forms.

In this case you have to create a file FormFolderPaths.xaml in the same folder as yourscript.py, because I will be referencing the name of the file inside the python file.

Here is the code:

<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:av="http://schemas.microsoft.com/expression/blend/2008" 
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
        mc:Ignorable="av"
        Title="Folder Path Picker Form" 
        Height="400" Width="300">

    <StackPanel Margin="10">

        <!-- Title -->
        <TextBlock Text="Folder Path Picker Form" FontSize="18" FontWeight="Bold" HorizontalAlignment="Center" Margin="0,0,0,10"/>

        <!-- Description -->
        <TextBlock TextWrapping="Wrap">
            <Run Text="This form allows you to pick three different folder paths. "/>
            <LineBreak/>
            <Run Text="Click the buttons to select the folders."/>
        </TextBlock>

        <!-- Separator -->
        <Separator Margin="0,10,0,10"/>

        <!-- Folder Path 1 -->
        <DockPanel Margin="0,0,0,10">
            <Label Content="Folder Path 1:" Height="25" DockPanel.Dock="Left"/>
            <Button Content="Browse..." Height="25" Width="Auto" Margin="5,0,0,0" Click="BrowseFolder1_Click"/>
        </DockPanel>
        <TextBox x:Name="FolderPath1" Height="25" Width="Auto" Margin="0,0,0,10" IsReadOnly="True"/>

        <!-- Folder Path 2 -->
        <DockPanel Margin="0,0,0,10">
            <Label Content="Folder Path 2:" Height="25" DockPanel.Dock="Left"/>
            <Button Content="Browse..." Height="25" Width="Auto" Margin="5,0,0,0" Click="BrowseFolder2_Click"/>
        </DockPanel>
        <TextBox x:Name="FolderPath2" Height="25" Width="Auto" Margin="0,0,0,10" IsReadOnly="True"/>

        <!-- Folder Path 3 -->
        <DockPanel Margin="0,0,0,10">
            <Label Content="Folder Path 3:" Height="25" DockPanel.Dock="Left"/>
            <Button Content="Browse..." Height="25" Width="Auto" Margin="5,0,0,0" Click="BrowseFolder3_Click"/>
        </DockPanel>
        <TextBox x:Name="FolderPath3" Height="25" Width="Auto" Margin="0,0,0,10" IsReadOnly="True"/>

        <!-- Submit Button -->
        <Button Content="Submit" Width="75" Height="25" HorizontalAlignment="Center" Click="UIe_button_run"/>

    </StackPanel>
</Window>
