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?

Regards

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.

Hi Nam DongKyun ,


We have reviewed your query regarding the issue with entering Korean text in the forum. When typing Korean, the first character entered disappears, and the second character is inserted into the cell. Additionally, when typing a Korean sentence and pressing the space bar, the cursor position moves to the beginning of the text.

 

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.

Kindly refer the below code snippet.

 

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

Thank you for your response.

I tried your method and it works in edit mode, not cell mode.

Also, if I move the cursor to the cell to the right of the current cell, it will start from the first cell.

If there are characters in the cell where I moved, the cursor moves to the first character and then to the last character before moving to the next cell.

The grid I'm currently using uses two different grids.

One uses c1flexgrid and syncfusion gridcontrol.

c1flexgrid is a grid that when you press the Korean keyboard toggle key in cell mode and start typing, it immediately enters edit mode.

and it immediately enters the edit mode and does not miss any characters.

But syncfusion gridcontrol, when I press the Korean keyboard toggle key in cell mode, I get the

but the moment I press the keyboard, the characters I entered are displayed in the normal order.

are not entered into the cell in the normal order.

The original multilingual input processor is not working properly, so currently, gridcontrol is using the

gridcontrol is not currently being used.

If you think about the global environment, you need to modify the input system.

If there is another way, please suggest it.

Thank you. Have a nice day.

Hi  Nam DongKyun,

We have reviewed your query, and you mentioned that you are unable to enter Korean text using the IME keyboard in cell mode. However, we were unable to replicate the issue. We were able to enter Korean text successfully using the IME keyboard, which immediately entered edit mode, and the value was displayed in the cell. When we moved to the next cell by navigating to the right, it successfully transitioned to the next cell. Additionally, when pressing the keyboard, the normal order was displayed in the cell.

 

We suspect that the issue may be caused by enabling the UseRightToLeftCompatibleTextBox property, which could lead to this behavior. If this property is set to true, we recommend changing it to false.

 

We have provided a sample and video for your reference. Kindly review the sample and confirm whether you are still experiencing the same issue with the provided sample. If we have misunderstood your requirements, please provide any video references to help us investigate further.

No matter how much I test it, it continues to behave strangely.

Attach a video.

If you watch the video, you'll notice that when you switch from English to Korean

and start typing

GridControl shows a small box in the top left corner of the screen.

However, c1FlexGrid does not show a small box on the top left of the screen and goes straight into edit mode without any problems.

Have a nice day.

Thank you.

Hi Nam DongKyun,


We have analyzed the reported problem from our end. 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 is a system-level behavior in Windows and is not specific to WinForms. It appears by default when using an IME for Korean or other complex scripts.

This behavior is not observed when entering English text because the IME is primarily designed to assist with typing in languages like Korean, Chinese, and Japanese, where a single keypress can yield multiple character options. English uses a one-to-one mapping between keys and characters, so there is no need for character composition or selection, and the IME’s suggestion box does not appear.

In our case, when editing a cell using Korean input, the first keypress appears in the IME's "Finalize the String" box. Subsequent keypresses are typed directly into the cell’s textbox. However, the caret position behaves incorrectly, causing the input order to appear inconsistent (not flowing left to right as expected).

To resolve this issue, we recommend setting the ActivateCurrentCellBehavior property to SetCurrent. This ensures that when the current cell is navigated via keyboard input, it will enter an editable state automatically. Once this is set, Korean characters can be typed directly into the cell in the correct order.

Kindly refer the below code snippet.

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