Screen jump – slight flickering

[hurricaneParticipant]

Hi There,

I am facing a problem when implementing jqxgrid. Problem is , when we do copy and paste on any cell then screen flickering we can see on that grid. It feels like focus is being lost and restored once event is completed. This is happening on the demo example which is listed on the website as well : http://www.jqwidgets.com/jquery-widgets-demo/demos/jqxgrid/#demos/jqxgrid/defaultfunctionality.htm

One thing to notice here, If I open this example from the demo list then only I am seeing this behavior. Opening this example using view in new window will not give this problem.

jqx version : 4.4.0
Diff browser versions:
Chrome : 59.0.3071.115
Mozilla : 54.0.1

Please confirm if this is very specific behavior because of any version mismatch or it is existing one. Kindly suggest a way to get away with this problem.

Regards.

Hello hurricane,

I do not see this problem occurring in our latest release v4.5.3.
Consider updating your project, the problem should be fixed then.

Hi Peter,

Sorry for the misunderstanding here! I am still experiencing this problem on the given demo list. I am using version 4.4.0 for my development , but the demo similar problem I am seeing on given demo list examples. I hope demo list examples are referring to v4.5.3.

Steps I have followed :
1. Opened : http://www.jqwidgets.com/jquery-widgets-demo/demos/jqxgrid/index.htm#demos/jqxgrid/
2. From left side option selected Default functionality
3. I am doing copy/paste on demo grid.

Hi Stanislav, Peter

We are experiencing problem with this issue more frequently since we are dealing with copy/paste functionality more often with the grids. Can you please update if there is any scope of this issue being considered for upcoming jqx release? if not soon, We would appreciate your guidance with providing temporary fix to this.

Regards.

Hello hurricane,

When we tested it, we saw that this issue mainly occurs when you have only selected the cell, it didn’t occur when you have started editing the cell.
Maybe you could try changing the editmode to click. If it works as you intended to, keep it until a fix comes out.

Best Regards,
Stanislav

Hi Stanislav,

I see that solution work only when I have to copy data to specific cell in editmode. Whereas, I am having a situation where data is getting copied from excel to the grid. It seems I may not be able to fit the solution which you are mentioning for this use case.

Let me know if you have any other thoughts.

Regards.

Hi Stanislav,

Also, I would like to register on more issue happening with the cut/paste functionality.

Steps I have followed :
1. Opened : http://www.jqwidgets.com/jquery-widgets-demo/demos/jqxgrid/index.htm#demos/jqxgrid/
2. From left side option selected Default functionality
3. Do copy the description written on the top of the grid. for example copy this to the clipboard (ctrl+c),
This demo illustrates the basic functionality of the Grid plugin. The jQWidgets Grid plugin offers rich support for interacting with data, including paging, grouping and sorting.

4. Now, Select first cell from the first column (i.e Chai (Product)). Do ctrl +x (cut).
5. select Chang from the second row and do ctrl+v (paste).
6. I am seeing that instead of result from 4th point , it is copying data of 3rd point.

Please update if you need more information.

Regards.

Hello hurricane,

Thank you for reporting the second issue as well.
You can take a look at our Data Binding examples. There are some examples of how to load from different sources.

Thanks Stanislav for your inputs. I got a situation where some of my data coming from database and rest of them I needed to copy it from excel or somewhere else. So far, I have used only single type of source binding to the grid. Not mix of (excel & database). Let me know if I am overlooking any of the examples here.

If you don’t mind me asking , Do you have any plans of considering these issues for upcoming releases ?

Regards.
