How to set all nodes checked = false, on a treeview

[Just Me]

I need to set all nodes on a treeview so that checked=0

Is there a good way to do that?


Thanks

Assuming that you mean after all the nodes have been added, you would have
to do a recursive read of all the nodes and set them to checked = false. I
am sure if you google you will find the recursive code for getting all the
nodes , (I do have a routine to do that but searching for it has not worked
to find that).

If you want to set them to checked = false when you load them, then you must
create a node and set it to unchecked and then add it as you would normally
do.

Here's a little something that ought to get you started....

HTH
Kejpa
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click

Dim oNode As TreeNode

For Each oNode In TreeView1.Nodes

oNode.Checked = CheckState.Checked

ToggleNodeCheck(oNode, CheckState.Checked)

Next

End Sub

Private Sub ToggleNodeCheck(ByVal Node As TreeNode, ByVal State As
CheckState)

Dim oSubNode As TreeNode

For Each oSubNode In Node.Nodes

oSubNode.Checked = State

ToggleNodeCheck(oSubNode, State)

Next

End Sub
