How to add a child node to a specific node in treeview?
Say i have "Item1" in treeview already, How do i add "SubItem1" to "Item1" as it's child node?
I know its probably really simple, but i tried lots of stuff, i just cant get it working.
Basically, it refuses to find the node when the root node contains an attribute.

When I do xml.SelectNodes("DataSet") with the xmlns in the root tag, it finds no nodes. If I remove the xmlns attribute, it works fine.How can I make it work while leaving the attribute?
Finding the level of the particular xml using a node value in .Net Experts ! This is my sample Xml.This is a tree structure and T->T.1,T.2->T.2.2,TA->TA.1 - this is the tree strucutre. I know the value of tag . ie 1232,1343.. etc.Using this ID how can I find that 1343 is coming under 1232. or 1490 is under 1090 which is again under 1232.Expected output : if i pass 1490 then I need to know 1490,1090,1232 etc (from that nodeto the top node).I am using .net 2.0
<Abc>
<A>
<Name>T</Name>

I have a TreeView that I am using for display purposes only. I don't want the user to be able to select any of the nodes. Setting the enabled property of the form to False doesn't suffice since it changes the entire look of the nodes.
I tried canceling the select action in the BeforeExpand event. It kind of works. It selects, then de-selects the item. I'm going to play around with other events to see

View 10 Replies1. I need to be able to store the STR MG INT and SPD somewhere when they create an item and make sure it is assigned to that item, and since I allow them to create unlimited item, I need this way to be dynamic (as in create variables as needed).
2. I need to find some way to make sure the user has selected an item name in the treeview (not type or main node).For example, they need to click Hockey Mask and then click the equip item button for it to work?
I'm trying to change the background color of a node that is being hovered over while the user is dragging items from a list box.I've gotten both functions to work separately, but while the user is dragging, the NodeMouseHover event does not fire. Is there a way to do both?
vb Private Sub trvNavigation_DragEnter(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles trvNavigation.DragEnter
If Me.CanMove(e) Then
e.Effect = DragDropEffects.Copy

Note: CanMove() is a function I made that verifies the dragged data. Nothing else. And I will change "Color.Blue" to a system color later.
I have an application where I'm allowing the user to edit the text of a treeview node. Is it possible to "lock" portions of the node's text to keep it from being edited?
For instance, if the text is "BK01" originally, can I keep the user from editing the "BK" prefix?
I currently validate the user's input when they are finished editing, but I'd like to keep them from entering incorrect information to begin with.

View 1 RepliesI have the following XML
<xml>
<ObsCont xCampo="field1">
<xTexto>example1</xTexto>
</ObsCont>
[code]....
Is there a way to get the content of "xTexto" inside the ObsCont that has "field2" value for the attribute xCampo using DataSet?It would be desireable to have a single liner like the following:
DataSet ds = new DataSet();
ds.ReadXml(StrArquivoProc);
ds.Tables["xml"].Rows[0]["field"].ToString();
//field == "information"
If I use the same method I'm not specifying that I want the one with the desired attribute.
