Release R3 2020 (LIB 2020.2.713)

I'm trying to use the new RadSyntaxEditor in a popup editor and I'm having issues and questions. I'm using it in a component built in code that is used to edit a SQL Query from a grid cell double click. It seems to work except when I press enter to insert a new line it does not do that, instead the default form button is fired to close the form. Note that I can launch the form to either show a multi-line textbox or a RadSyntaxEditor depending on the input parameters. It works perfectly with the textbox. The issue is with the RadSyntaxEditor 

I also have the following questions:

I cannot find any documentation on loading text into the RadSyntaxEditor is my code correct for this?

I cannot find any documentation regarding the Document property - where do I find that?

I cannot find anything on how to get the text out of the RadSyntaxEditor when I'm done. Is my code correct on this?

Here are my code snippets:


        private void GvMrgLtr_CellDoubleClick(object sender, EventArgs e)
        {
            var m = MethodBase.GetCurrentMethod();
            try
            {
                if (sender is HostedTextBoxBase sndr)
                    sndr.Text = MemoDialog.ShowDialog(sndr.Text, "Edit", 0, false, false, true);
            }
            catch (Exception ex)
            {
                MessageBox.Show($@"{m.Name} : {ex}");
                Log.Error(ex, m.Name);
            }
        }

Release R1 2020 SP1

RadSyntaxEditor allows the end-users to select a part of the text and drag the selection to a new position.

Currently, there is no public API that allows you to control whether the drag operation should start, on what target line you are dragging over (and whether you can drop on it) and when you drop the selection.

Add ability to disable horizontal scrollbar and enable word wrapping - fixed width of editor and if the word cannot fit - it is moved to next line.
