View 8 RepliesI have a treeview control where I am dynamically selecting a node depending on user interaction. when a node is selected I want to be able to have the scrollbar go to the location of that selected node in the tree. The scrollbar is simply made by overflow:auto in the div tag where the treeview is located. Can someone give me some detailed code to accomplish this?

I have this code to select first node of TreeView. But when page loads the by default root node is other than first, I want to set the selected node as top most by default. Here is my code in page load but it's not working:
Dim nodes As TreeNodeCollection = TreeView1.Nodes
If nodes.Count > 0 Then
' Select the root node
TreeView1.SelectedNode = nodes(0)
End If
This gives the blue underline error on this line:TreeView1.SelectedNode = nodes(0)
The error is: "Selected Node Property is read Only"

View 4 Repliesfor some reason I have to click a node in a treeview twice for it to register as selected. I've checked with treenode.isselected() and treeview.selectednode() and with both two clicks is required to show the selected node (1 click continues showing the previously selected node as selected) while the visual highlight/selection works perfectly with 1 click. Any suggestions on what may be wrong/how it could be fixed? (The node selection code is in the nodeclick event)

I have been playing with, and researching, this all day and can't figure it out. I have a Windows Explorer style form with a TreeView and a ListView. I've populated the TreeView with directories and when a node is selected, the ListView fills with the contents of the directory associated with that node. No problem there, but I want to be able to select a directory in the ListView and automatically select the associated node in the TreeView, just like it works in Windows Explorer. All the information I've found online tells me how to populate the ListView from the TreeView, but I haven't found any good examples of how to populate the TreeView from the ListView.

1. 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 Want To Make One Scrollbar To Scroll Two Richtextboxes At Once
View 1 RepliesI have two panels, and I want them to both scroll horizontally with one scroll bar, but I only want one of them to scroll vertically. So if I have a large panel on autoscroll, it works fine for that panel, but I have another smaller panel above that, could I make the smaller panel scroll horizontally with the larger panel's horizontal scrollbar?

I am currently working on a VB.Net program where there are two parallel multiline text boxes like this.
----- -----
| | | |
| | | |

I would like that when one text box is scrolled, the other is scrolled as well. I was wondering if there was a Scroll event that could trigger the change the position of the scroll bar of the two text boxes.
i have a treeviev and listbox.i want to display the selected contents of treeview into the listbox.my code is working for file but not for folder. means i want, if the all contents of folder ABC(i.e all files) are selected then in listbox i want to show the only path of folder not the seperate path of each file.
View 1 RepliesI have a custom contro which inherits directly from Treeview. Is there any way to handle some event related to when the TreeView Scrollbar appears (it does this when the height of the stack of visible nodes exceeds the height of the control) or "disappears"?
I realize if could set up a function which checks the ItemHeight * Nodes.Count, and compares this to the control height. However, this seems clumsy. I have been exploring the object browser (and anylized TreeView with Reflector) and have not found what I am looking for. If there is a way to access the ScrollBar Property at ALL within TreeView, I have not found it.
I want to add key while adding node to the treeview but I don't see key property in the treenode. I am using following code
objAddSubFolders = New TreeNode
objAddSubFolders.Text = arrListDisplayFolders(intCountSubFolders)
objAddSubFolders.Name = arrListDisplayFolders(intCountSubFolders)
objParentNode.Nodes.Add(objAddSubFolders)
i want to add a node just above all removable drives from the thread I asked about in before. I decided that I don't want to have "C:" as a node, instead I just want my program to be the node. I've worked with this before but i can't figure it out without messing up what I already have.
View 6 RepliesAll my TreeView nodes have a unique ID for their Node Depth.
I want to set Checked=True on the TreeView Node which matches a certain value.
Currently I'm doing the following:Dim value As Integer = 57
For Each n As TreeNode In tvForces.Nodes
If n.Value = value Then n.Checked = True
Next
Is there a better way of finding the Node which I want to set as Checked=True rather than looping through each node?
I'm looking for something like:Dim value As Integer = 57
n.FindNodesByValue(value)(0).Checked = True
Is there anything like this that I can use?
