  • Drag and Drop grouping in Datagrid

    0 comments  /  posted by  Silverlight Show  on  Apr 26, 2010 (2 months ago)
    In this post at Lee's corner you can find out something more about drag and drop grouping in Datagrid.

    Most 3rd party components have a datagrid where you can a drag column header to the area above the grid to group the data. Here is one way to do the same with a regular datagrid.

    David Anson demonstrates how to simply and flexibly create a grouped list of items by using IValueConverter.

    A customer recently asked how to implement a simple "grouped ListBox" experience in Silverlight (now available in desktop, mobile, and extra crispy flavor!), so I dashed off this sample to show one way that's pretty easy to work with.

  • Grouping Data in a Silverlight DataGrid

    In this post Tim Heuer discusses DataGrid grouping.

     In Silverlight 3 you have access to PagedCollectionView (add a reference to System.Windows.Data to get it).  This is a view that enables you to add sort and group descriptors.  In my initial loading code I instantiate a new PagedCollectionView passing in my List<Person> as the enumerable type.

    Karl Shifflett is ready with the next sample in the WPF Sample Applications Series. This sample is the result of the question “how can I do multi-level grouping?” and provides a brief description of the problem, the solution and full source code.

    WPF provides the CollectionViewSource for codeless sorting and grouping of data.  The SortDescriptions and GroupDescriptions collections can be modified at runtime if desired.  The SortDescription provides the ability to set the sort direction as I’ve done for the Sales.

    In this article Harsh Bardhan explores how to group data from a static datasource. He then connects to database and shows how to group the data from the database.

    While using the DataGrid in Silverlight 2, a common requirement was to group similar records (For e.g. group all records of particular city together). We got a similar mail from one of our visitors Rachida, who wanted to know how to group data in the Silverlight DataGrid. Well in Silverlight 3 DataGrid, this feature has been added and now we can group records with ease.

    What is a Pivot table/grid? According to Wikipedia it is a data summarization tool found in spreadsheet applications. Still when I was a child I learned that people understand the best when they see an example.

    Consider you have a table that contains the nutrition of given food, say a pizza:

    Group Name Quantity
    Carbohydrates Total carbohydrates 27.3
    Carbohydrates Total disaccharides 5.7
    Carbohydrates Total polysaccharides 21.6
    Minerals Calcium 147
    Minerals Phosphorus 150
    Minerals Potassium 201
    Minerals Copper 0.13
    Minerals Magnesium 19
    Minerals Sodium 582
    Minerals Selenium 4
    Minerals Total iron 0.7
    Minerals Zinc 1.07
    Vitamins Beta-carotene 173.8
    Vitamins Nicotinic 1.5
    Vitamins Total vitamin B6 0.127
    Vitamins Total vitamin D 0.3
    Vitamins Total vitamin E 2.1
    Vitamins Vitamin B1 0.1
    Vitamins Vitamin B12 0.59
    Vitamins Vitamin B2 0.16
    Vitamins Vitamin C 10

    In the data above you see that every nutrition is contained in a specific Group - 3 groups and 21 nutrition in total.
