We are using the DropTargetMarkerBrush to highlight when a user enters the droptarget but onsome machines the highlight is visual wrong.In the picture you can see the green highlight to the right when it should be to the left markeringthe box with dotted line.
Do you have any idea what could be wrong?
My team and I have done an initial investigation into this behavior you are seeing, and this doesn't seem like something that we have seen before. As such, I have a couple of questions for you on this matter. Would it be possible for you to please provide some information regarding the following?
1. By chance, are the machines where this issue exists touch-screen capable?
2. What is the specific version of Infragistics controls that you are using in this case? For example, if you are using 18.1, this number would look like 18.1.20181.XXXX and can be found on the properties of the DLLs that you are including.
3. Would it be possible for you to include a sample project that demonstrates the behavior you are seeing in this case?
Please let me know if you have any other questions or concerns on this matter.
Hello Andrew,Sorry for the delay but I have been waiting some answers from my customer.
We have made some investigations on different configurations but we haven't found any common issue.At the beginning we called it the "HP bug" because it was only found on HP machines. We now have found it on other machines both with an without touch-screen. At the moment we working with 17.2 but there are plans to upgrade to 18.2 as we have some other bugs.This work will probably be done later this summer.
As we are approaching our release, we have decided, for the moment, to remove the use of DropTargetMarkerBrush. We will try to add it again when we make the upgrade to 18.2.
It is interesting that this issue was originally only found on HP machines on your end, but as you are currently able to reproduce this behavior on other machines as well, both with and without a touch-screen, this eliminates this piece of the issue.
It is unfortunate that you have decided on a removal of the DropTargetMarkerBrush as a result of this issue, although to continue investigating into this behavior, I believe an isolated sample project demonstrating the behavior you are seeing will be necessary.
