One thing that lacks in the SilverLight is the DataSet. If Infragistics could add a DataSet as it has done it in the other components, there will be a huge help for developers!
Here are some of the features that make the DataSet (and family) very usefull:
1.) The dynamic columns of datatable. Meaning, I can add, edit, delete columns. Also, I can choose the column's data type.
2.) The rowfilter of dataview
3.) I can sort the dataview very easily.
I will add more later
I am using a Silverlight implementation of DataSet (and family) from your competition. With your permission, I will post the name of the product here. But I like the UI component of Infragistics better.
James:
Can you describe your scenario more? What features of DataSet do you find useful?
