Get the row index via a treeListCommandEventArgs

[David]

Hi,

I was wondering how can I get the index of row in the UpdateCommand events of a TreeList. In a RadGrid, it would be like this :

Guid uniqueIdentifer= Guid.Parse((RadGrid1.Items[e.Item.ItemIndex] as GridDataItem)["UniqueIdentifier"].Text);

But if doesn't work with a treeList. In fact, the proprety e.Item.ItemIndex doesn't seem to exist. So, I look around to found something, but I had no luck. So, may someone tell me how to retrieve the index of the selected row via a updateCommand.

Thank you

Hello David,

This depends on the EditMode you are using. If using InPlace edit mode, the e.Item property in the event handler refers to the TreeListDataItem that is in edit mode. In this case you can cast e.Item to TreeListDataItem and get its DisplayIndex:

((TreeListDataItem)e.Item).DisplayIndex

In fact, if you need to access the data item with this approach, it is already there - e.Item is your data item.

The other approach is if you are using EditForms or PopUp edit mode. In this case, your edited item is of type TreeListEditFormItem and its .ParentItem property gives you the respective data item and its DisplayIndex:

((TreeListEditFormItem)e.Item).ParentItem
