C# - File Dialog
private void SetupFilePicker()
{
    filePicker.PlaceholderText = "Choose a document...";
    filePicker.IsReadOnly = true; // Force use of button
    
                // Set folder icon
    filePicker.ButtonImageIdle = Properties.Resources.folder_icon;
    
    filePicker.ButtonClick += (s, e) => 
    {
                using (var dialog = new OpenFileDialog())
        {
                if (dialog.ShowDialog() == DialogResult.OK)
            {
                filePicker.TextContent = dialog.FileName;
            }
        }
    };
}

Example 2: Folder Selection

Using the picker for directory paths.

C# - Folder Dialog
private void SetupFolderPicker()
{
    folderPicker.PlaceholderText = "Select destination folder";
    
    folderPicker.ButtonClick += (s, e) => 
    {
                using (var fbd = new FolderBrowserDialog())
        {
                if (fbd.ShowDialog() == DialogResult.OK)
            {
                folderPicker.TextContent = fbd.SelectedPath;
            }
        }
    };
}

Example 3: Material Style

Applying a modern material design look.

    picker.PickerStyle = SiticoneFilePickerStyle.Material;
    picker.BorderColor = Color.Gray;
    picker.FocusBorderColor = Color.DeepSkyBlue;
    
                // Remove background for true material feel
    picker.BackgroundColor = Color.WhiteSmoke;

Example 4: Read-Only Display

Using the control to display a path that cannot be changed.

C# - Read Only
private void ShowOutputPath(string path)
{
    outputPicker.TextContent = path;
    outputPicker.IsReadOnly = true;
    
                // Customize disabled/readonly look
    outputPicker.DisabledColors.BackgroundColor = Color.White;
    outputPicker.DisabledColors.TextColor = Color.DarkSlateGray;
    
                // Hide button since it's read-only
    outputPicker.ButtonSize = 0; 
}
