How to collapse/expand groups in code

[Konrad Sikorski]

Hi,

I have application which contains only RadGridView. Items in this grid are grouped by one of entity property. I would like to remember which group is collapsed and when application will be run again, automatically collapse these rows. In other words I want to remember last application state.

Thank you for any suggestions.

Hello,

 You could use the ExpandGroup method of the RadGridView to expand the saved group.

To use ExpandGroup I need to check which group is Expanded. I can use gridControl.Items.Groups but this objects don't have property IsExpanded. How can I do that?

Items.Groups[index] returns object, so you need to cast it to IGroup.

 If you wanted to expand a group you'd do:

grid.ExpandGroup((IGroup)grid.Items.Groups[0]);​

grid.ExpandGroup((IGroup)grid.Items.Groups[0]);​
