[Solved] Group Header Agregates and Slideout Functionality

[Laura]

I'm working with the Silverlight RadGridView control and looking to complete a project that has 3 levels of aggregate roll-ups (Department, Project, Cost).  On the project and the price levels, I intend to include a cell that contains an image with a "slide-out" menu with various pieces of functionality.  The cost row is the basis of the grid.  It is divided into costs for the 12 fiscal periods in a month.  These each of these aggregate cost values need to be rolled up to the Project and Department level.  

I've looked into using nested grids and grouping, but each seem to have their issues.

Nested Grids:
Nested Grids do not allow the columns to line up.  Therefore, it will be difficult to line up the aggregates for each of the fiscal periods.

Grouping:
Grouping appears to only allow for "Group Footers".  I was hoping to have all the Grouping details appear in the Grouping Section or, at a minimum, a "Group Header".

I've attached an image that gives a rough idea of my POC.  I'm simply asking the forum for what they feel is the best approach for some of these ideas.

Any help would be greatly appreciated.  Thanks!

I currently have the fly-out menu working by setting MouseEventHandlers on certain cells on the grid RowLoaded event.  Does anyone have any suggestions for the grouping?  I am considering replicating the grouping manually by adding my own +/- images hiding/showing the rows manually.  Is this an acceptable solution or is there some way to leverage the existing telerik grouping functionality?  I can set the curGridViewRow.Visibility = System.Windows.Visibility.Collapsed but it doesn't cause the grid to refresh and consume the whitespace.

Once again, any direction would be appreciated.

Thanks,
~Keith

Hello Laura,

You can put different information in the Group Headers as well. Please check this online demo and group by Date for example.

The RadGridView provides methods to expand or collapse a group, namely ExpandGroup(IGroup) and CollapseGroup(IGroup).

IGroup groupToExpand = this.clubsGrid.Items.Groups[1] as IGroup;

this.clubsGrid.ExpandGroup(groupToExpand);

Hope this helps.

Best wishes,

I see that different information can be included in the headers.  However, can the columns be displayed and can images be included so I can have "fly-out" functionality on the image?
Thanks,
