MMF2 - Datagrid Bugs

I have found two major bugs with the Datagrid Object.

1. If you create datagrid with a number of lines so that the vertical scrollbar is displayed you will notice that if you click and drag up and down everything is fine. However, if you click on the scroll up arrow or the scroll down arrow it will:

a. as you scoll the header line near the arrow will not continue to display correctly. It will be partly blank.

b. you will be forced to click on an empty area of the screen to stop scrolling and allow you to reselect the drag bar again or the other arrow.

c. cause the application to hang.

2. The scrollbars do not seem to update correctly if the datagrid in design view is changed. They will remain on when they should be off if you resize the datagrid.

It would be nice if someone could correct these problems. I am going to have to cover up the up arrow and down arrow so users are forced to only select the drag bar else the application hangs up and does not display correctly.

Could someone fix these problems and release a new version?

Could someone verify this for me?

Create a datagrid with five columns.
Add 300 lines. Try using the drag bar to move up and down.
Now click on the up arrow to scroll.

Let me know if it causes problems.

Thanks

I also have these problems in my project, plus these:

Datagrid is very useful, anyway. It would be great to have this fixed, though.

Thanks for the reports I will make sure Francois knows about this thread so he can look into it when he gets some free time.

It appears some of these issue seem to occur over time. At first the datagrids seemed to work correctly but then problems began to happen.

I created some of the datagrids using the clone feature. I have also coded to to create rows using "add row". I don't know if these actions contributes to the problems but it would be great if Fancois could look into the datagrid component.

I wish there was a way for him to hook into my system so he could see the screens and what happens.

Thanks Jeff.

While I was beta testing some software, I used to record all the mistakes / bugs that were hard to explain with screen-recording software, the programmers just loved it. Of course this takes lots of time, especially if you want to do it properly - just throwing an idea out.

Here is a picture showing how the bugs effect the datagrid:

In this picture if you click on the up arrow you MUST click on the yellow area to cause it to lose focus to be able to click on the datagrid drag bar or down arrow. Then if you do click in the drag handle of the scroll bar you see the heading goes white.

Also notice that the column sizes all change to a fixed size that cause problems with the headings being cut off on the left and right size. Prior to adding the rows the columns were set correctly and no changes in code tell the datagrid to alter column widths. It appears that when a new row is added the column widths are reset???

I have also tried to repeat this error using the datagrid with 10 columns and 300 rows. The above datagrid has 300 rows. But I have not been able to get the error the repeat. So it appears to happen over time. I have also noticed that the datagrid will no longer fully respond to design-time edit changes were it did at first. Other datagrids in the application also show similar problems.

The link to your picture is not working.

Slashes were backwards for a start:

Are you seeing the smaller picture in the post?
I'll check the link.

Another problem with Datagrid is you are not allowed to set the heading for cell 0,0 like you can for cell 0,1 0,2 etc... You can only do it in code. You should be able to set a column heading in the edit dialog for cell 0,0.

UH...I works on my side. Dynasoft are you able to see it?
