Hi Telerik,

i am searching for the best approach to expand all items in a grid.

It is a 5 Level hierarchy with dynamically created columns, which should be set in editmode.

The ItemCreated and Databound Event have to be fired.

Do you have a simple way to do this?

Thanks for helping!

At the moment i set all items of the first level in editmode and expand the first level.
For expanding i use following code:
protected void RadGridHierarchy_PreRender(object sender, EventArgs e)
{
            if (_expandedItem != null && _expandedItem.Expanded)
            {
                if (_expandedItem.HasChildItems)
                {
                    foreach (GridTableView view in _expandedItem.ChildItem.NestedTableViews)
                    {
                        foreach (GridDataItem item in view.Items)
                        {
                            item.Edit = true;
                        }
                        view.Rebind();
                    }
                }
            }
 
            //Edit on all Items in Level 1
            for (int i = 0; i < RadGridHierarchy.MasterTableView.Items.Count; i++)
            {
                RadGridHierarchy.EditIndexes.Add(i);
                RadGridHierarchy.EditIndexes.Add(RadGridHierarchy.MasterTableView.Items[i].ItemIndex);
            }
}
 
 
protected void RadGridHierarchy_ItemCommand(object sender, GridCommandEventArgs e)
{
        if (e.CommandName == RadGrid.ExpandCollapseCommandName)
        {
                _expandedItem = (GridDataItem)e.Item;
                SaveGridValues();
 
                if (_expandedItem.Expanded)
                {
                    _expandedItem = null;
                }
        }
}

Hello Lars,

You can use the following property to expand all items:
<telerik:GridTableView ... HierarchyDefaultExpanded="true">
Or expand/collapse all in-built functionality:
http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/declarative-relations/defaultcs.aspx

For traversing the items and putting them on edit mode:
http://www.telerik.com/help/aspnet-ajax/grid-accessing-cells-and-rows.html

In case you are using In-Place:
http://www.telerik.com/help/aspnet-ajax/grid-put-all-items-in-edit-mode-no-additional-rebind.html
http://www.telerik.com/help/aspnet-ajax/grid-traversing-detail-tables-items-in-grid.html

Finally, I suggest you to check the new Batch edit feature provided by RadGrid:
http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/batch-editing/defaultcs.aspx

Hope this helps.
