Any clues?

I'm trying to put a page break before a sub report. I've read in a few different spots that this can only be done with sections. I don't have any groupings and apparently the designer can only create groups and not additional detail sections. Any suggestions? Adding code is not a good solution for me since others who are not developers will be creating these reports.

How to show/hide text box controls at runtime. I am unable to do this...Please help me out

I downloaded & installed the latest Telerik Reporting (at the time this thread was posted), and also installed DevExpress 12.2.

I wanted to change my report service from DevExpress to Telerik's one but re-creating every single report from scratch in report designer is too time-consuming. I found some information about DevExpress converter but it was to use DevExpress 8.2.

My WebApp is based on asp.net MVC and published on Azure, I don't know if there is any work-around to have this task done and get it to work properly on Azure, and if there is one how could I do that? Really need help on this.

Pdf report is showing correct format of the dataset, but exporting to excel has too many hidden rows and columns. How to resolve this?

In my report, I have a group footer that contains subtotals for the group. I would like to ensure that it is always printed on the same page as the data in the group, rather than by itself on the following page.

There does not seem to be any option to accomplish this. Basically, what I want is a "keep with previous" option. If the group is printing toward the bottom of a page such that there will not be room for the totals, I would rather have the whole group (or part of it) moved to the next page than to have the totals appear alone at the top of the next page.

Is there any way to do this?

Rick.
