Hi,

in this thread (Bindig to a Dictionary) you gave an example on how to use an object containing a dictionary as data source for a gridview. I adjusted this example for a current project and it worked very well.

In particular,
 - I add not only Objects of Type String but also of Type DateTime and Double to the Dictionaries "Attributes" in class LayerData
- further I set as DataType String, Double or DataTime for each GridViewDataColumn in the grid

These extensions allowed me to do convenient formatting of the output. Further I could implement sorting by writting my on code in an EventHandler of the Sorting event.

Now, where I am stuck is grouping. Whenever I drag a group header onto the grouping panel I get an exception.

Could you please provide me with a hint how custom grouping could be done in this case?

Thanks,
Stefan

Hello Stefan,

Please open a support ticket and attach me your project. I will try to enable grouping for it .
In generally I can not give you a descent hint without seing your code.
However there is a new property in later versions  of RadGridView  - GroupMemberPath of the column. It may be helpful in your case.

All the best,
