Please let me to explain how we handle any feedback provided by our customers. When a client reports a bug or a feature that is not currently available in the Telerik UI for WinForms suite, the support engineer that is currently handling the ticket, logs a public feedback item on behalf of the customer in our feedback portal: https://feedback.telerik.com/winforms 

Then, when we prioritize the issues/features that our users report, we are taking into consideration the following key points:
- Is the reported issue a show-stopper;
- Does the reported issue have a work-around;
- What is the severity and nature of the issue (for example – memory leak issue, performance issue, functionality issue, styling issue);
- How many users have reported the issue / How many users have voted for a feedback item.

Since there is a suggested solution in my previous reply for the file dialogs and there are other issues/features which require more urgent attention, I can't give you an exact time frame when this item will be addressed. However, we will do our best to introduce the desired functionality as soon as possible. If more customers vote for it, we will increase its priority.

Have you tried the previously suggested solution in your project? Does it achieve the behavior you need?

If you need any further assistance please don't hesitate to contact me.

I have also updated your Telerik points.

Currently, the possible solution that I can suggest is to manually set the ExplorerControl.CurrentDirectoryPath property according to the pasted path in the breadcrumb:

        public RadForm1()
        {
            InitializeComponent();

            this.radOpenFileDialog1.OpenFileDialogForm.ExplorerControl.PathNavigationBreadCrumb.BreadCrumbElement.TextBoxEditorElement.TextBoxItem.PreviewKeyDown += TextBoxItem_PreviewKeyDown;
            this.radOpenFileDialog1.ShowDialog();
        }

        private void TextBoxItem_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)
        {
            if (e.KeyData == Keys.Enter)
            {
                string path = this.radOpenFileDialog1.OpenFileDialogForm.ExplorerControl.PathNavigationBreadCrumb.BreadCrumbElement.TextBoxEditorElement.Text;
                if (Directory.Exists(path))
                {
                    this.radOpenFileDialog1.OpenFileDialogForm.ExplorerControl.CurrentDirectoryPath = path;
                }
            }
        }

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
