Hide AllThe BandedList data region is a collection of free-form bands. By default, it is composed of three bands: a header, a footer and a detail band. Bound report controls in the detail band repeat for every row of data. The header and footer rows render once at the beginning and end of the BandedList, respectively, and are a good place for titles and grand totals.
Click inside each band to reveal its properties in the Properties window, or click the four-way arrow to select the entire data region and reveal its properties. Properties for this data region include the following.
Band Properties
| Property | Description |
|---|---|
| CanGrow | Change to True to allow the data region to grow vertically to accommodate data. |
| CanShrink | Change to True to allow the data region to shrink if there is not enough data to fill it. |
| KeepTogether | Change to True to have ActiveReports attempt to keep all of the data in the band together on one page. |
| PageBreakAtEnd | Change to True to insert a page break after rendering all of the data in the band. |
| PageBreakAtStart | Change to True to insert a page break before rendering any of the data in the band. |
| RepeatOnNewPage | With header and footer bands, repeats the band on every page when the related details span multiple pages. |
BandedList Properties
| Property | Description |
|---|---|
| DataSetName | Select the dataset to use in the data region. |
| KeepTogether | Change to True to have ActiveReports attempt to keep all of the data in the data region together on one page. |
| NewSection | Change to True to render the data region in a new section. |
| OverflowName | Select the name of the OverflowPlaceHolder control in which to render data that exceeds the allowed space for the data region on the first page of the report. |
You can add group header and group footer bands. Report controls in these bands repeat once for each group instance. You can also nest groups, plus, in RDL reports, you can nest other data regions in any header or footer band. Grouping in the BandedList is similar to grouping in the Table data region. You can provide a grouping expression for each group, and also sort the groups.
 |
Caution: You cannot sort the detail data in a BandedList, so any sorting of this type must be done at the query level. |
BandedList Dialog
Properties for the BandedList data region are available in the BandedList dialog. To open it, with the BandedList selected on the report, under the Properties Window, click the Property dialog link.
The BandedList dialog lets you set properties on the data region with the following pages.
 |
Note: You can click <Expression...> in many of these properties to open the Expression Editor where you can create an expression to determine the value. |
General
Name: Enter a name for the banded list that is unique within the report.
Tooltip: Enter the value or expression you want to appear when a user hovers the cursor over the banded list in the viewer at run time.
Dataset name: Select a dataset to associate with the banded list. The combo box is populated with all of the datasets in the report's dataset collection.
Has own page numbering: Select to indicate whether this banded list is in its own section with regards to pagination.
Page Breaks: Select any of the following options to apply to each instance of the banded list.
- Insert a page break before this banded list
- Insert a page break after this banded list
- Fit banded list on a single page if possible
Header and Footer: Select any of the following options.
- Repeat header band on each page
- Repeat footer band on each page
Visibility
By default, the banded list is visible when the report runs, but you can hide it, hide it only when certain conditions are met, or toggle its visibility with another report control.
Initial visibility
- Visible: The banded list is visible when the report runs.
- Hidden: The banded list is hidden when the report runs.
- Expression: Use an expression with a Boolean result to decide whether the BandedList is visible. True for hidden, False for visible.
Visibility can be toggled by another report control: Select this check box to display a toggle image next to another report control. This enables the drop-down box below where you can specify the report control that toggles the visibility of the BandedList. The user can click the toggle item to show or hide this BandedList.
Navigation
Document map label: Enter an expression to use as a label to represent this item in the table of contents (document map).
Bookmark ID: Enter an expression to use as a locator for this BandedList. You will then be able to provide a bookmark link to this item from another report control using a Jump to bookmark action.
Groups
Click the plus sign button to add a new group to the BandedList, and delete them using the X button. Once you add one or more groups, you can reorder them using the arrow buttons, and set up information for each group on the following tabs.
General
Name: Enter a name for the group that is unique within the report. This property cannot be set until after a Group on expression is supplied.
Group on: Enter an expression to use for grouping the data.
Document map label: Enter an expression to use as a label to represent this item in the table of contents (document map).
Parent group: For use in recursive hierarchies. Enter an expression to use as the parent group.
Filters
You need to provide three values to add a new filter to the collection: Expression, Operator, and Value.
Expression: Enter the expression to use for evaluating whether data should be included in the group.
Operator: Select from the following operators to decide how to compare the expression to the left with the value to the right.
- Equal Only choose data for which the value on the left is equal to the value on the right.
- Like Only choose data for which the value on the left is similar to the value on the right.
For more information on using the Like operator, see the MSDN Web site. - NotEqual Only choose data for which the value on the left is not equal to the value on the right.
- GreaterThan Only choose data for which the value on the left is greater than the value on the right.
- GreaterThanOrEqual Only choose data for which the value on the left is greater than or equal to the value on the right.
- LessThan Only choose data for which the value on the left is less than the value on the right.
- LessThanOrEqual Only choose data for which the value on the left is less than or equal to the value on the right.
- TopN Only choose items from the value on the left which are the top number specified in the value on the right.
- BottomN Only choose items from the value on the left which are the bottom number specified in the value on the right.

- BottomPercent Only choose items from the value on the left which are the bottom percent specified in the value on the right.
- In Only choose items from the value on the left which are in the array of values specified on the right.
Selecting this operator enables the Values list at the bottom. - Between Only choose items from the value on the left which fall between the pair of values you specify on the right. Selecting this operator enables two Value boxes instead of one.
Value: Enter a value to compare with the expression on the left based on the selected operator. For multiple values used with the Between operator, the lower two value boxes are enabled.
Values: When you choose the In operator, you can enter as many values as you need in this list.
