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);
}
}

using Telerik.WinControls.UI;
using Telerik.WinForms.Controls.SyntaxEditor.Taggers;
using Telerik.WinForms.SyntaxEditor.Core.Text;
namespace P3CMS.Components
{
internal static class MemoDialog
{
public static string ShowDialog(string text, string caption, int maxLength = 0,
bool ro = false, bool spellcheck = true, bool sqlSyntaxHighlight = false)
{
var originalText = text;
var memoDialogForm = new RadForm
{
Width = 500,
Height = 700,
FormBorderStyle = FormBorderStyle.Sizable,
Text = caption,
StartPosition = FormStartPosition.CenterScreen
};
var textBox = new RadTextBox
{
Left = 50,
Top = 40,
Width = 400,
Dock = DockStyle.Fill,
Multiline = true,
AcceptsReturn = true,
Text = text,
ScrollBars = ScrollBars.Both,
MaxLength = maxLength,
ReadOnly = ro
};
var textDocument = new TextDocument(text);
var radSyntaxEditor = new RadSyntaxEditor
{
Left = 50,
Top = 40,
Width = 400,
Dock = DockStyle.Fill,
Document = textDocument
};
var tagger = new SqlTagger(radSyntaxEditor.SyntaxEditorElement);
radSyntaxEditor.TaggersRegistry.RegisterTagger(tagger);
var checker = new RadSpellChecker { AutoSpellCheckControl = textBox };
if (!spellcheck)
checker.AutoSpellCheckControl = null;
var bottomPanel = new RadPanel { Height = 60, Dock = DockStyle.Bottom };
var confirmation = new RadButton
{ Text = @"Ok", Left = 50, Width = 100, Top = 8, DialogResult = DialogResult.OK };
var cancel = new RadButton
{ Text = @"Cancel", Left = 200, Width = 100, Top = 8, DialogResult = DialogResult.Cancel };
confirmation.Click += (sender, e) => { memoDialogForm.Close(); };
if (sqlSyntaxHighlight)
memoDialogForm.Controls.Add(radSyntaxEditor);
else
memoDialogForm.Controls.Add(textBox);
memoDialogForm.Controls.Add(bottomPanel);
bottomPanel.Controls.Add(confirmation);
bottomPanel.Controls.Add(cancel);
memoDialogForm.AcceptButton = confirmation;
memoDialogForm.CancelButton = cancel;
if (!sqlSyntaxHighlight)
textBox.Select(0, 0);
return memoDialogForm.ShowDialog() == DialogResult.OK
? sqlSyntaxHighlight ? textDocument.CurrentSnapshot.GetText() : textBox.Text
: originalText;
}
}
}
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.
