Hide extra column for hierarchy indicator

[Pawel]

Hello

I have grid something like in picture gridview.png (attach files) and I am loading data to it depending which action will be triggered by application user.

I know there are two cases:

• none of loading data have childrens 
• all or some of loading data have childrens

For first case gridview.HierarchyChildTemplate must be equal to null and ChildTableDefinitions should be empty (Count = 0).
For second case I load DataTemplate for gridView.HierarchyChildTemplate and I add adequate GridViewTableDefinition. But when I am dealing again with first case I do:

gridview.HierarchyChildTemplate = null<br>
ChildTableDefinitions.Clear()

and extra column for hierarchy indicator stays and it should be gone.

Hi,

I checked the attached image and I can see there is just one column for the hierarchy.
Would you please point me (mark clearly) where on the picture I can observe the issue?

Attached image is just a example of similar grid which I have in my application. Problem is when sometimes I want to load data with hierarchy structure and sometimes I won't. When I do

gridview.HierarchyChildTemplate = null<br>
ChildTableDefinitions.Clear()

extra column for hierarchy indicator doesn't disappear.

Do you want me to prepare a sample application?

Hello Pawel,

It would be indeed very helpful if you can provide a sample application illustrating the issue. Having your exact setup I will be able to advise further.

You can take a look at this blog post for a reference on how to isolate an issue.
