Default grouping in RadGridView

[DANIIl]

Hi!

 I use GridView for displaying objects such as:

 class Detail {

     string Name

     string Value

     string DetailGroup

}

 I create collection and bound GridView ItemsSource to it. In gridView i create 3 columns for each property. Then i start my application I want to the default group was by DetailGroup property. I use GroupingDescriptor, but i don't understand, how can i connect it with My DetailGroupColumn or how to bing it to the Collection property (DetailGroup).

 Will be grateful for help, I hope somebody had such problem.

Hello,

You can group on the DetailGroup Member. You can also check the documentation on Grouping for further details.

As to the second part of the question, would you like to populate the column bound to DetailGroup to another collection? Maybe something like GridViewComboBoxColumn?

You can also check the topic on Defining Columns.

Dimitrina, thanks for the help. I want set default grouping. In attach files i showed it! In figure i showed, what i want, then i started my application. This grouping must be default.

Hi,

You can indeed specify the Member you wish to be grouped on. In addition, when the user drags the column header to the group panel in order to group data, you can subscribe for RadGridView.Grouping event and introduce some modifications to the default case.
