Hello,
We would like to use SyntaxEditor by providing our own programming language definition. It would be great to have the ability to feed SyntaxEditor with a language definition file. This file could be use an EBNF-like format to provide syntax coloration.
Thanks & regards,
I do have some feedback on this component. I love it, but of course there are some areas where improvement can be made. For instance, in the screenshot below, I have highlighted some words where improvement can be made.
- ‘1,2,3,5’ – Literals in SSMS are Red
- ‘ER – 100% OF MEDICARE’ – OF is highlighted in Blue. It is contained in a literal and shouldn’t be highlighted
- ISNULL – Is a function and should be highlighted in Blue
- typing from right to left
- proper selection, navigation between RTL chars
- proper insert, delete, cut, copy, paste operations (modifications) sign
We want to have the option to replace texts only in a selected part of the document.
Use Notepad++ as a reference to check this feature.
When using XML Tagger, XML Folding tagger with XML text document, the folding tagger freezes the UI while typing.
Generally in Visual Studio, the XML Folding tagger is processed in background while in SyntaxEditor this is done on the UI thread.
Several optimization options might be applied:
- process xml folding in background
- process folding similar to process search while typing - a period of inactivity time is needed to invalidate the search / folding
- caching - if the edit does not change the folding configuration, no processing and redrawing of folding is required
- some parts for extracting tooltip content and folded content should be optimized
--Install Bopomofo or Quick input method (Traditional Chinese).
--Open the Telerik SyntaxEditor in a WPF application.
--In any text input field, enter an Alt code (e.g., Alt+0160 for a non-breaking space).
--Attempt to type any Chinese characters immediately after entering the Alt code.
Current Behavior:
-Bopomofo IME:
-- The user cannot type any Chinese characters after entering an Alt code.
-- Switching the language (e.g., pressing Shift) allows English input, but Chinese input remains blocked.
Quick IME:
-The input method automatically switches to English after entering an Alt code.
-The language indicator still shows Chinese, but characters typed are in English.
T-o resume Chinese input, the user must click another text field, alt-tab to another window, then return.
Expected Behavior:
-Users should be able to continue typing Chinese characters after entering Alt codes without needing to manually switch inputs.
-The IME state should remain consistent, allowing uninterrupted input.
The position of the popup representing the IntelliPrompt is wrong when shown on the monitor with the higher DPI scale, in a setup with two monitors with different DPI settings. For example, if one monitor has 100% DPI scale and the other 125%, the position of the popup will be wrong when the app is on the 125% monitor.
To work this around, use the Caret visual as the PlacementTarget for the popup and set its offsets to 0 after it is shown.
private void RadSyntaxEditor_PreviewKeyDown(object sender, System.Windows.Input.KeyEventArgs e)
{
if (KeyboardModifiers.IsControlDown && e.Key == Key.Space)
{
e.Handled = true;
var editor = (RadSyntaxEditor)sender;
CaretPosition startPosition = new CaretPosition(editor.CaretPosition);
CaretPosition endPosition = new CaretPosition(editor.CaretPosition);
editor.IntelliPrompts.CompletionListWindow.Show(startPosition, endPosition);
editor.IntelliPrompts.CompletionListWindow.HorizontalOffset = 0;
editor.IntelliPrompts.CompletionListWindow.VerticalOffset = 0;
}
}
private void RadSyntaxEditor_Loaded(object sender, System.Windows.RoutedEventArgs e)
{
var editor = (RadSyntaxEditor)sender;
var caret = editor.FindChildByType<Telerik.Windows.Controls.SyntaxEditor.UI.Caret>();
editor.IntelliPrompts.CompletionListWindow.PlacementTarget = caret;
editor.IntelliPrompts.CompletionListWindow.Placement = System.Windows.Controls.Primitives.PlacementMode.Bottom;
}
