Adding a Scroll Pager tool throws exception

Seveno Developer · Post by **Seveno Developer** » Mon Dec 19, 2016 11:49 pm

Hi,

I've reported a previous bug regarding scroll pager serialization issue (ID1395] http://bugs.teechart.net/show_bug.cgi?id=1395). Now that it has been fixed and for this I've just have upgraded to the latest build (4.1.2016.10261). I am able to open the previously saved charts with scroll pager but found that the the scroll pager tool is not working.

To reproduce, add a series and then add a scroll pager tool from the tools tab. Index out of range exception thrown.

Can we please get a quick solution to this? I have access to source for any modification required.

Regards,

Khaled

Hello Khaled,

Attached here:

a small project that references the latest public version of TeeChart.dll. When I run this project here, I get the following result:

do you get the same at your end? If not, could you please send me some code with which I can reproduce your problem at this end?

an update - I can see that there is, in fact, a couple of problems with ScrollPager serialization *at designtime*, one of which has been present for the last two releases and one of which is present in the last release. I am looking at it now and will get back to you when I have resolved the issues.

If you have the source code, within the ScrollPager.cs unit you can make these changes:

: change2.PNG (29.89 KiB) Viewed 15101 times

these should fix the designtime issues for you.

Hi Chris,

That has resolved the exception, but after the change in code the subchart is not scrollable at all. I can not change the selection/ boundary for the scrollable chart in design mode.

Hello,

I've made a number of changes to ScrollPager.cs, and although changing the boundaries with the mouse at designtime as one can at runtime is not possible (the boundaries can be changed using the Chart Editor, however), changes at designtime are now more accurately reflected at runtime. Possibly the easiest way to get these changes to you is by email - if you could give me your email I can sent this modified unit to you.
