Hello,
I have a hierarchical grid with one checkbox column "selected" that is updatable. When I click the checkbox and immediately after press the "+" button to expand the grid, the changes to the checkboxis are not saved and dissapears.
Please see screenshot in attachment.
Please advice how I can influence the behaviour of this.
Kind regards,Michael
Hello Michael,
Thank you for posting in our community!
I have created and attached a sample which represents the desired behavior. In this scenario multiple row selection is enabled both for the parent and for the child grids.
Feel free to use and modify the sample. If you need any further assistance please let me know. If so, in order to investigate further I will need a sample representing the specificities of your case.
Hello Dimka,
Unfortunately your example doesn't cover the problem.
The problem is unrelated to the subrows being selected or not. The problem is that when checking the box in the top row and then pressing the expand button, the box that was just selected is not saved and is unselected again.
In attachment you will find an example. Follow these steps to simulate the problem:* Start the application* click the checkbox in the first row (Name = George) * press the "+" expand button on the same row
As you can see now the checkbox of the first row is no longer checked.The same behaviour happends when i select the checkbox and then press in the "group by"-area.The changes are only saved if I click on the word "george" for example.
Hope that will explain my problem better.
Kind regards,
Michael
I have tested the sample you have provided. The reason for the behavior observed is that when a cell data is updated it in needed the current cell focus to be changed before another event is fired. In this scenario when the expand sign is clicked the expand event is triggered but the focus is still on the cell containing the checkbox. As a result data is lost and the new check box state is not saved. A possible approach is implementing the built-in RowSelection feature with checkboxes enabled. In order to use this feature it is also needed the Selection feature to be added. I have inserted code snippet for your reference bellow:
model.Features.Add(new GridSelection());
model.Features.Add(new GridRowSelectors() {
EnableCheckBoxes = true,
EnableRowNumbering = false,
}
I have also attached a modified version of the sample you have provided. The custom checkbox column is removed in it the built-in one is used instead.
Feel free to use the sample and modify it. If any further questions arise don’t hesitate to contact me again.
Thank you for the sample. I can confirm that this works as expected in the current case of "just selecting rows".However, the problem remains that while editing rows and doing the actions described, that the changes done by the user are not changed and discarded.
I think this should be considered as a bug and should be solved in a future release.
IgniteUI provides a solution for cases when more than one cells in a row is needed. When a row is edited a pop-up with “Done”, “Cancel” buttons is displayed and user may confirm the changes by pressing “Done”. That ensures that changes are submitted correctly.
Thank you for your feedback!
If you have any further questions don’t hesitate to contact me again.
Thanks for the information.
I hope that in the future a solution will be provided for cases where only one cell in a row is needing updating.
