Hi,

I'd like to know what is the criteria for items' vertical placement when the timeline item source is organized by groups. In my current scenario I would not like to have any group with a height greater than the rest. I thought, from observations, that this situation only occurred when the items' period overlapped, but apparently that is not all there is to it.

Also, in case I do have items with overlapping periods in the same group, is there a way to order them vertically? I'm attaching a picture to better describe my question: in this case, the second group occupies a larger area because one of its items got placed in a different height! Thanks in advance.

Regards,
Takeshi

Oh, while I'm at it: is there a way to remove the [+] sign beside the group description?! Thanks again!

Hello Takeshi,

The criteria for placing any item in a different row from the previous one is the overlapping. If the RadTimeline control detects that two items are overlapping (even with fraction of the second) it will place one of the items on different row. This criteria does not change when there is grouping.

Regarding your question about controlling the positioning of the items, the answer is yes. You can define custom row index generator class. In it you will be able to define custom logic based on which the items will be positioned. You can take a look at our online demo to see a sample implementation.

Regarding the requirement to hide the "+" sign of the groups, you can achieve this by setting the GroupExpandMode property of the RadTimeline to None. This will prevent the groups from collapsing and remove the sign.

I hope this information is helpful.
