Hello,

I'm currently using a RadSyntaxEditor for user text inputs. The problem I'm facing happens when a user tries to write anything using an Asian IME, for example the Japanese IME with Hiragana input. Instead of having a predictive text dropdown open at the point of the caret, it opens a little input box in the corner of the screen and the predictive text dropdown opens at that position.

Is there a way to have the predictive text dropdown open at the position of the caret in the SyntaxEditor?

For reference, I have reproduced the issue in the Telerik UI for WPF SDK Samples Browser, the "Custom Language Highlighting" demo and attached the screenshot of the observed behaviour.

Any help would be appreciated, thank you.

Hello Felix,

IME input is still not supported in our SyntaxEditor control. Th origin of this issues is that the Caret element in the editor is a Control and to have IME opening close to it, the Caret should have characteristics or inherit from TextBox. Plus some issues with IME selection with mouse/keyboard and selection of full width symbols need to be addressed in order to provide full support for this feature. That is why I logged a feature request on your behalf in our feedback portal:
