Single/Update edit button for whole TreeList

[Gijo]

I have a TreeList that displays data in a hierarchy and has got three columns and one of the column is editable. I want to have a single edit/update button on the top the TreeList (rather than havong edit/update button for each row), clicking on which will make the Entire TreeList editable and updatable.  Any help Appreciated. Thanks in Advance.

I figured it out and turned to be simple.

1. Set AllowMultiItemEdit= "true"
2  I put a button on top of the grid an in the Click event, loop thru and set item.Edit = true; 

 

    foreach (TreeListDataItem item in RadTreeList1.Items)

 

    {

        item.Edit =

true;

 

    }

Please let me know if the same can be accomplished without looping.
