Korean typing input in winforms gridcontrol.

[Nam DongKyun]

Hello.

I am suffering from Korean typing input in winforms gridcontrol.

When I input Korean by keyboard typing, it behaves abnormally.

In winforms gridcontrol, inputting English by keyboard typing works fine.

/// Abnormal behavior when entering Korean ///

- When entering Korean, the first character entered disappears and the second character is entered into the cell.

- When typing a Korean sentence and entering the space bar, the cursor position moves to the beginning.

/// Normal behavior when typing in Hangul ///

- If you press the shortcut key F2 at the position of the cell you want to enter and type Hangul, it works normally.

  However, what I want is to enter the input textbox in the grid without pressing F2.

  What I want is for the BrowseOnly property to be True, and when I start typing in Korean, I don't have to press F2.

I want to enter the Korean input mode in the grid's text input box window directly, just like when typing English.

Is there any solution?

Hi Nam DongKyun,

We regret for the inconvenience we caused.

We have analyzed the reported issue from our end and have determined that the reported scenario is not a problem, but rather a default behavior of the system. When entering Korean characters in a cell, a small popup may appear to provide character suggestions that can be selected from. This popup is known as an "Input Method Editor" (IME) "Finalize the String" box.

The "Finalize the String" box, which is typically part of the Input Method Editor (IME) user interface when typing in Korean or other complex scripts, is a system-level behavior in Windows, not something specific to WinForms. It appears by default when you use an IME for Korean input.

The reason we don't see a "Finalize the String" box when entering English text is because the Input Method Editor (IME) is primarily designed to assist with inputting complex characters in languages like Korean, Chinese, and Japanese, where a single keypress can result in multiple character options. In contrast, the English language primarily uses a one-to-one mapping between keys and characters. This means that pressing a key typically results in a single character being entered, and there is no need for character composition or selection. Therefore, the IME's "Finalize the String" box is not activated when typing in English because there are no complex character compositions to suggest or select.

In our case, when we edit the cell using Korean keys, the first typed key value is placed in the IME "Finalize the String" box. Then the followed keys were typed in the cell textbox, but the order of the caret position is wrong, so typed key values are not in the flow of left to right. You can resolve this problem by setting the ActivateCurrentCellBehaviour as SetCurrent. This means that when the current cell is moved through keys, the current cell will be navigated and in an editable state. Now we can be able to type the Korean letters directly. For your reference, attached the sample.

Kindly refer the below code snippet.

gridControl1.ActivateCurrentCellBehavior = Syncfusion.Windows.Forms.Grid.GridCellActivateAction.SetCurrent;

We hope this helps. Please let us know, if need any further assistance.

Thank you for your quick response.

If I write the code as you informed me, the

it will always change to edit mode wherever the cursor is positioned.

What I want to implement is that if I receive an input event while not in edit mode, I will get a

I want to keep the IME status of Korean or other non-English language as it is.

I want to change a cell in the current grid to edit mode.

Is there any other way to do this?

Is this a basic problem with the Windows input system?

Is it too complicated to hook(?) the IME state in the Windows keyboard input processing, so I have to use the above method?

I ask because I'm not very good at programming hardware systems.

I am using the syncfusion component well.

Thanks.

Best regards.
