- Sort by multiple columns when you click in the column header
- Use the
property to specify a function to apply styles to rows and columns of the control
- Use an expandable navigation tree in a column to control the visible rows of the control
- Collect multiple columns under a single column heading
- Span multiple columns with an item renderer and use multiple item renderers in the same column
Working in a combination of these features to create something new was fun. I wanted to create a summary row for a group, but I didn’t want any of the tree structure to be shown. More like a divider between my grouped data. Here’s the basic example:
I started out with just a simple ADG that grouped by a column. Grouped data is flat data that you arrange in a hierarchy for display.
To group data, you specify one or more data fields that collect the data into the hierarchy using the GroupingCollection class as the dataProvider for the ADG. The
method applies the settings of the GroupingCollection class to the data. You must call this method any time you modify the GroupingCollection class. Since I was calling a groupingFunction to group my data, I call
on initialize of the ADG.
By default, GroupLabel is the field name for the data items added to the flat data to create the hierarchy. We’ll use this for our summary row divider.
That gave me a tree structure in the display. Next I added a renderProvider
I’m going to go ahead an post this up, I should be able to complete the rest of the description later.
