[Solved] RadOpenFileDialog select initial file

[Luigi]

Hi,
I open a RadOpenFileDialog  setting FileName with the full path of an existing file.
In the edit box in the low part of dialog I can see the path, and, if I click ok I get the file selected.
But in the list of files the path is not selected (the folder is also correctly set).

How can I select correctly the file and automatic scroll the view in order to see the seelction

Thank you
Luigi

Hello Luigi,

The RadFileDialogs component does not provide this functionality out of the box, however, it can be achieved with a bit of custom logic.

More specifically, you could subscribe to the Loaded event of the RadOpenFileDialog instance and retrieve the FileBrowserListBox element via the ChildrenOfType extension method. Then, check if its items contain a file that matches the one that is set on the FileName property of RadOpenFileDialog. If there is, retrieve it and set it to the SelectedItem property of the FileBrowserListBox element.

The following code snippet showcases this suggestion's implementation:

private void OpenFileDialog_Loaded(object sender, RoutedEventArgs e)
{
	RadOpenFileDialog openFileDialog = (RadOpenFileDialog)sender;

	FileBrowserListBox fileBrowserListBox = openFileDialog.ChildrenOfType<FileBrowserListBox>().FirstOrDefault();

	if (fileBrowserListBox != null)
	{
		FileSystemInfoWrapper selectedFileSystemInfoWrapper = fileBrowserListBox.ItemsSource
			.Cast<FileSystemInfoWrapper>()
			.Where(x => openFileDialog.FileName.Contains(x.Name))
			.FirstOrDefault();

		if (selectedFileSystemInfoWrapper != null)
		{
			fileBrowserListBox.SelectedItem = selectedFileSystemInfoWrapper;
		}
	}
}

With this being said, I attached a sample project for you to test, which contains this suggestion's implementation.
