Saving/Restore group collapse state

[Loy Chan]

With the GridSettingsPersister class, I can save the group by expression and it works great.

In addition, I have a situation where the user wants to save the collapse state of some of the groups. Is this possible?

For example, the user will:

1. Group the list by 'project status'
2. Collapse specific groups (i.e. Pending, Cancelled)
3. Go into the details screen (i.e. another page so I store the gird settings here)
4. Go back to the list (where I need to restore the grid settings)

At step 4, all the specific groups that have been collapse are now back to their un-collapsed state.

Thoughts?

Thanks,

Loy.

Hello,

 You can access the GridGroupHeaderItems of the grid and save their expanded / collapsed state:

var groupHeaderItems = RadGrid1.MasterTableView.GetItems(GridItemType.GroupHeader).Cast<GridGroupHeaderItem>();
        foreach (var groupItem in groupHeaderItems)
        {
            var expanded = groupItem.Expanded;
        }

All the best,
