A Guide to Smart Data Regions in C# .NET Reports

Smart Data Regions: From Fields to Useful Report Regions Fast

If you build reports for a living, you already know the loop:

• Add a dataset.

• Drag fields onto the designer.

• Realize the grouping is wrong.

• Swap fields around.

• Try a chart.

• Decide the chart needs different categories/series.

• Repeat.

It’s not hard, it’s just repetitive. Smart Data Regions in ActiveReports.NET v20 is aimed squarely at that workflow: get you to a solid first draft quickly, while keeping the designer fully in control the whole time.

The rest of this post walks through a sample report using a small JSON dataset you can drop into a sample project.

What 'Smart Data Regions' Does

Smart Data Regions generates common report regions like:

• Tables

• Tablix

• Charts

The key idea is simple:

1. You select the fields you want to work with.

2. ActiveReports generates multiple region suggestions (not a single guess) with a short description of what each option does.

3. You pick one, insert it, and then edit it like any other report region.

Think of it as “autocomplete for report layout,” not “AI takes over your report.”

The Dummy Dataset You Can Use (JSON)

This dataset models a basic SaaS scenario: support tickets with common fields you’d actually report on (category, priority, assignee, times, SLA, satisfaction).

It’s intentionally shaped so you can create meaningful regions such as the following quickly:

• trend by day

• breakdown by category/priority

• team performance

• SLA compliance

• satisfaction

You can embed this JSON in your sample project and bind it as a data source. For the DataSet’s JSON Path query, just use: $.tickets[*].

Walkthrough: Build a Sample Report With Smart Data Regions

This walkthrough assumes you’ve got a report designer open and a data source pointing at the JSON above (or your equivalent model). The exact clicks vary a bit depending on whether you’re using a standalone designer integration or embedding in your app, but the flow is the same.

1. Start with a dataset and pick a "report question" 

Let’s build a report that answers three questions:

1. What’s ticket volume over time?

2. What categories and priorities are driving the most work?

3. How is the team doing on response time and SLA?

That maps nicely to three regions: a chart, a breakdown table/tablix, and a KPI-style summary.

2. Generate a trend chart (created date + count)

Right-click on the dataset and pick “Add Data Display Control”, then select “Generate with AI”.

Select these fields:

• createdDate

• ticketId (or any field you can count)

Generate suggestions. You should see options that look like:

Pick the chart option that matches your intended granularity. Insert it.

What to check after insertion

• Make sure the date grouping is what you want. If you want “by day”, confirm it isn’t grouping by full timestamp.

• If your dataset spans a longer period, weekly/monthly grouping often reads better.

3. Generate a breakdown table (category + priority)

Select:

• category

• priority

• ticketId (count)

Generate suggestions. Good ones usually include:

• Grouped table by category with priority breakdown

• Tablix with categories as rows, priorities as columns, counts in cells

• Chart alternatives (stacked columns by priority)

If you want something that’s easy to scan and export, pick the tablix style (category rows, priority columns). Insert it. Here’s an example of the output from the tablix and chart above:

4: Generate a team performance region (assignee + response metrics)

Select:

• assignee

• firstResponseMinutes

• resolutionMinutes

• slaMet

Generate suggestions. You’ll likely see:

• Table grouped by assignee with averages (avg response, avg resolution)

• Table with SLA met rate by assignee (percentage)

• Chart options (bar chart of avg response time by assignee)

Pick a table suggestion that includes:

• average first response

• average resolution

• SLA met rate (or count met vs total)

Insert it.

What to Tweak

• Format minutes as something readable (hours).

• Include the Ticket IDs.

• Move grouped values and aggregates to group headers or footers.

• Styling.

After a couple minutes of tweaks:

What Makes This Useful in Practice

The biggest win isn’t that AI can create “a table.” You could do that in a minute anyway.

The win is that it gives you multiple sensible starting points quickly:

• table vs tablix vs chart

• different groupings

• different category/series mappings

• different aggregations

That matters because report design is usually exploratory. Stakeholders often don’t know what they want until they see a couple options.

With Smart Data Regions, you can:

• generate 4–6 viable layouts in a couple of minutes,

• pick one,

• then do the real work: labeling, formatting, business logic, parameters, and polish

Limitations and Expectations

Smart Data Regions is best at producing the “80% draft”:

• region structure

• reasonable grouping/aggregation

• chart/table choice exploration

It won’t know your business rules automatically. If your SLA logic is “Critical is 4 hours, High is 8 hours” you’ll still implement that. Same with parameterization, drill-through, subreports, and any domain-specific calculations.

That’s fine. The feature is meant to reduce repetitive layout iterations, not replace your reporting logic.

Opt-in Note (important for real projects)

All AI features in ActiveReports are entirely opt-in. Nothing is enabled by default, and your project will not contain AI functionality unless you explicitly add and configure it.

Wrap-up

If you want a quick way to explore report layouts without doing the drag-drop dance five times, Smart Data Regions lands in a pretty practical spot: fast suggestions, multiple options, and you’re still editing normal report regions at the end of it.
