Hi,

I just spent approximately 4 hours wondering why a report I was creating kept inserting pagebreaks after a row group in a crosstab even though I had set GroupKeepTogether=False. I discovered that some old parent row group that I had since deleted was still visible (but greyed out) via the report explorer even though you couldn't see it in the group explorer. This deleted parent row group had its GroupKeepTogether set to True and it was still having an effect on the report layout even though I had deleted the group long since. Why is this happening? It's quite unintuitive and confusing that deleted groups don't seem to be truly deleted and can still have effects on the report.

follow up: Is there any way for me to "clean up" the groups in the report explorer view without having to recreate the entire crosstab from scratch? There does not seem to be an option to delete them. I had some trouble creating the desired layout so I ended up creating and deleting lots of groups so it looks like a total mess and apparently can also have unintended side effects.

Hello,

We are not aware of such issues with the groups and I have not been able to reproduce the problem. 

How do you delete the groups? Do you just delete the rows? The best way to get rid of table/crosstab/list groups is through the Group Explorer. When clicking on a group, a menu will open, and if you choose Delete Group you will be presented with the option to delete the group only or to delete the group and the rows and columns with it. Deleting the group and the rows is the most secure way to be sure that the group is gone for good.

Since the product version is not mentioned here, If what I am saying does not apply on your end, please make sure that you have updated to the latest version and try again.

Thank you for using Telerik Reporting!

Hi,

Please find attached my reproduction of this behavior. As you can see the crosstab has only one row group in the group explorer which has its PageBreak property set to None. However, in the report explorer you can see a greyed out row group I deleted with PageBreak=After which results in page breaks being inserted even though the group was supposedly deleted. In order to reproduce this it appears that you have to first delete the column only and then delete the group and you are left with a grey "ghost group" in the report explorer. If I delete both at once this does not seem to happen. I'm on version 15.0.21.120

Thank you for the provided report.

Indeed, there is a rowGroup group in the report explorer affecting the layout that is not visible in the crosstab's group explorer.

I have created a bug report on your behalf and have attached this sample report as an example of the issue. I also cast your vote for it to increase its priority and also to ensure that you will receive a notification when the problem is fixed - Deleted groups still show up in report explorer and affect layout.

Thank you for using Telerik Reporting!
