Hey All
Can the treeview control display a friendly name to the user and store a id as a value. ?
I mean i have list of customers to user i want to display the customers name and to the application when a user selects a customer i wish to pass the customers id to what ever code ive wrote ?
Unless I'm mistaken (but I don't believe so) Microsoft removed our beloved "Key" property. But for what you are wanting, I think you could use the "Tag" property off the node object.
When the user clicks a node, just pass the Tag property along.
That's exactly what I do - use the tag property.
have you got any good clean code examples of this ?
Ive got a private variable to the form
Private CustomerNode As New TreeNode
and in my onload event i have
CustomerNode.Text = strTitle
CustomerNode.Tag = currentRow("customerid")
TreeView1.Nodes.Add(CustomerNode)
this is contained within a loop of a dataset
For Each currentRow In mCustomerDs.Tables(0).Rows
next
In my data i will have customers with the same name but im getting this error
can not add or insert the item "MY CUSOTMERS NAME" in more than one place. you must first remove it from its current location or clone it; Parameter name Node ????
any ideas
Hi.
You just need to set the variable to a new instance of a treenode before adding it.
CustomerNode=New TreeNode
CustomerNode.Text = strTitle
CustomerNode.Tag = currentRow("customerid")
TreeView1.Nodes.Add(CustomerNode)
nice one pax i managed to work that out last night
however i seem to be getting duplicate entries for each node
it gets to the 3 or 4th one in the tree and then starts duplicating
im using the clear method but dosnt seem to do much
its as soon as the first db entry is null it does it
any ideas
hmmm...not to sure. Never actually tried that before but it sounds like there might be some thing going on with the loop it self.
I assume there's a While...End While or something of that nature.
Could it be that it skips a MoveNext for the recordset/dataset thus adding the same node twice?
