i want showing/hiding to sub-node of CollapsingRecordNode at Demo1 sample
here is base collapsingnode…
RootNode
+ A-ListGroup
AA-Node
AB-Node
+ B-ListGroup
BA-Node
BB-Node
+ C-ListGroup
CA-Node
CB-Node
if
RootNode.A-ListGroup.AA-Node.Visible = false;
and
RootNode.B-ListGroup.Visible = false;
Result is…
RootNode
+ A-ListGroup
AB-Node
After…
if
RootNode.A-ListGroup.AA-Node.Visible = true;
and
RootNode.B-ListGroup.Visible = true;
Result is originally collapsingrecordnode.
RootNode
+ A-ListGroup
AA-Node
AB-Node
+ B-ListGroup
BA-Node
BB-Node
+ C-ListGroup
CA-Node
CB-Node
Give me some idea.
thanks.
So… you are not collapsing, you’re hiding a sub-item with no way for the user to “show” it?
My guess is when you set the item (like AA-Node) to visible=false, it just creates a hole in the CollapsingRecordNode without collapsing it. is that right?
like below CollapsingRecordNode…
Root Node
+ A-ClassNode
AA-SubNode
AB-SubNode
AC-SubNode
+ B-ClassNode
BA-SubNode
BB-SubNode
if BA-SubNode and BB-SubNode is Visible = false,
i want to be automatically hide B-ClassNode.
after that
if BA-SubNode Visible = true,
i want to be automatically show B-ClassNode with BB-SubNode
is it possible?
If you set any CollapsingRecordNodeItem to visible=false, you have to then call CollapsingRecordNode.LayoutChildren(null) to property layout the node. Note if you expand and collapse the parent, the invisble Item will now be visible, as that’s how the whole expand/collapse thing works.
Hiding/showing the parent if all the children are hidden is something you're going to have to handle as you set the child's state.
Ultimately, I think you're working against the design of the node here. Since it already uses visibility for collapse and expand, throwing in extra things that play with visibility is going to lead... well, I'm not sure.
I think the better strategy is for you to actually remove BA-SubNode, etc if you don't want them to be a part of the heirarchy.
ok. thanks jake.
