View 2 RepliesIm working on a project that has an explorer like treeview control. The control works great. What I need it to do though is once it gets to the end of the folders and sees a valid text file i want the text file to open into the textbox I have placed next to it while still opening anything that is not a plain text file the way it normally would. The code I have now is below and works to open the application or file with its corresponding program but I cant get the text file to populate the textbox.
[Code]...
A second issue im having trouble with is after the file has been opened in the textbox i want a button to send the text to a webpage form that is in the app. Its an actual webpage that I have embedded into the app. with the webrowser control. Its a simple textbox on the webpage. So basically I need to double click the file on the treeview that opens the file into the textbox(editor) I have made then with a single click of the button select all/copy then paste it into the box on the webpage all within the same application.
I have a file open that I can use to manually open a text file in the textbox that works great. I have tried to manipulate that to the treeview with no success. I have the button to select all and copy. Now if I can just get the text file to open on double click from the treeview and the send to the webpage control and my app is complete. Well almost Im working on a spellcheck feature for it but that's just extra functionality id like to add.

I have a function to rename a TreeView Node to a TextBox text.. When the user clicks a button with a little icon on it, a new Node is created. It is called Graphic_(0,1,2 ect.) So it changes the number to the TreeView Node count.
E.g
Graphic_0
Graphic_1
ect.
But, the user can also Delete the nodes and Rename them..
Sooo... the problem is, that if the user renames a previous Node, and calls it Graphic_ and then the NEXT number to occur, 2 Nodes will be the same, and I don't want that.
E.g
Graphic_0
Graphic_1
Graphic_4 <<<< User renames to up coming node number..
Graphic_3
So what I want is to prevent 2 Nodes being the same.. how do I change the UPCOMING Node name to the missed out Node, in our example: Graphic_2.
i want to give focus to a textbox after a node is selected in treeview and also keep selected node higlighted?

i have a treeview say TV1 and another Treeview Say TV2.. Now TV1 Contains all nodes for user rights. and i want to add to tv2 only selected nodes.Like TV1 is
Node 1
....Child of Node 1 (Level 2)
.........Child of Child of Node 1 (Level 3)
what i want is that when i select Level3 Node it should chek TV2 for the parent of this node. if parent exist it should add the node under the same parent. if parent does not exist it should check for Level 1 Node and if it exist it should add Level 2 Node and then Level 3 Node. Otherwise it should add Level 1 , Level 2 and then Level 3 Nodes in order.
I have a class, let's call MyClass. In this class, I have a TreeView property let's call myTreeView..In my code, I populate the Nodes of this TreeView so I can use it later on.Then, when it's time to actualy use it, I haven't been able to take all the nodes from myClass and put them in a Tree View Control on my form.[code]The weird thing is that when debugging, the TreeView in MyClass is well populated with the proper values and in the loop, newNode isn't empty, there's actually something but for some reason it's not showing anything.

View 1 RepliesIs it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?

View 12 RepliesThe TreeView uses in its underlying implementation the TreeNodeCollection. The TreeNodeCollection in almost every overload of the add method asks for a key.It also implements indexOfKey and ContainsKey yet there appears to be no way to determine the key of a node from the node itself or from any of the events you would typically use such as TreeView_AfterSelect().
Am I correct or is there in fact someway to retrieve the key from a node or event which I have overlooked? And assuming I am correct. Why on earth was it implemented in such a way? The only thing I could think of was that perhaps TreeNodeCollection.Key is deprecated? But I see no mention of this...
PS: I am aware of the TreeNode.Tag property and how it can be used to the same effect.

I'm working with a TreeView in a VB.NET to C# conversion project. I have this VB.NET WinForms code
Dim Arguments1 As String = path & "" & fs & " ls " & TreeView1.Nodes(ccc).Name
and I need the C# code. I got this far
string args = path + "\" + fs + " ls" + ...
I would assume it would be
.Items[ccc]
but there is not name attribute in that
I have been looking for a some working code for the last couple of days to set up a treeview in my WPF app to display some database data. I use VB as i am much more confident in it - which drastically limited the code examples out there. More examples i found used manually entered data to populate each node versus a database which was little help. I finally found some code which bound the each node to a query and related the query via a DataRelation. Great this should work perfect!
The example used the Northwind database so I changed it to my database and plugged in the queries. To my shock the treeview populated fine except.... all the data is invisible.
Here is the code:
Imports MySql.Data.MySqlClient
Imports System.Data
Imports System.ComponentModel
[code]....
and here what i end up with the data seems to be there but you can't see it.PS there may be some confusion as to the objects. I went back tried to keep as close to the original code as possible when i discovered the problem only replacing the queries with my own - the original code used "Categories" and "Products" where as I "use Distributors" and "Titles"

The parent nodes are populated through the table "tblINLOGNAAM" The childnodes are populated by "qryINLOGNAAM_GEBRUIKER_DR" When I click the parentnode I don't want anything to happen.But when I click a childnode I would like the ID of that name (wich is stored in the table "qryINLOGNAAM_GEBRUIKER_DR" with the name "Gebruiker_ID") to show so I can make a master detail relation with a datagridview.My problem is that I cannot get the gebruiker_id from the table "qryINLOGNAAM_GEBRUIKER_DR" when I click the childnode.
