I'm trying to make it to where when I highlight a TreeNode, it displays the every one of it's ChildNode.Text into a Textbox, but if the highlighted node has no children, it simply displays the Node.Text of the node that is highlighted into the TextBox...
Here's an easier explanation just in case:
Dim ParentNode As TreeNode = TreeView.Nodes.Add("Parent")
Dim ChildNode As TreeNode = ParentNode.Nodes.Add("Child")
If ANodeIsClicked Then
If TheClickedNode = HasChildNodes Then
Textbox1.Text = ClickedNode.Children.Text
Else If TheClickedNode = HasNoChildren Then
Textbox1.Text = ClickedNode.Text
End If
End If
End If
I have a tree view with a parent node. parent node will have 2 or more child nodes and the nodes data will come from a access database table. if I select any one of the child node with the mouse it will display the SUM of the child node's data in a label control below the tree view control. the access datable table might look like this [code]...
I want to do like the picture. Select a child node and it displays the sum of the titleid associated with it in a Label Control. I add my project here so that you can take a look at, what I am trying to do.
I have a richtextbox, when I leave it for example to go to another panel where I want to manipulate the selected text I can no longer see the selected text. Is there a way to make it still show the highlight?
I have a datagridview and in the _CellValidating event I am checking a cell to make sure it is filled in. If it is not, I want to stop editing, display a msgbox, and highlight the particular cell. Here is my code :
If e.ColumnIndex = 2 Then If e.FormattedValue = "" Then If Me.dgvFish.IsCurrentCellDirty Then MsgBox("Sample Number is a required field.")
[code]....
For some reason, I can't get the cell's backcolor to be filled in.
I have a form1 with a splitcontainer. I have put a button on the left panel, whenever user click the button, form2 will be displayed in the right panel.The question now is, i am not allowed to highlight the textbox in form2 with mouse. But i still can use the keyboard to highlight.
1) Replace textbox with richtextbox
2) set formborderstyle to Windows.Forms.FormBorderStyle.None.
Im working with MDI parent/child objects. when closing the child objects i need the child to check to see if it is the last child object before closing. i couldn't find anything on google, maybe im searching for the wrong thing.
I have a dataset that is being generated from an XML file.
This dataset has two tables (User and UserSecurity) - that is related because they both have the same primary key. [i know, the tables should probably be combined, but this is the data that I have to work with][code]...
I have a vb.net application that uses ShowDialog() to open child screens.
Long story short, I had issues with focusing the control if I opened IE on top of my program without minimizing the program. Once I reactivated my program and closed a child window, IE would show again instead of my program. I fixed this by setting the owner of my form.
Now I have another issue. After setting the owner, the parent (text) name of my form is now being shown at the top of the application when a child screen is open instead of the parent name. How can I fix this to show only the child's text form name when a child screen is open?
I'm trying to add a treenode to a listbox... say the TreeNode is named "Blue", when I add it to the listbox with Listbox.Items.Instert the output it gives me is "TreeNode: Blue"... How do I do this without having it bind the "TreeNode:" part to the output?
I'm writing a bit of code that I want to populate a TreeView, which it does quite successfully, but I also want to put a Dictionary in the Tag of each Level 1 child node. Once the Tag has been set to the Dictionary, is there any way I can modify the dictionary, without redeclaring the Tag.For Each verse In Verses
Dim _verse = verse.ToString.Trim Dim _node As TreeNode = New TreeNode(_verse.Split(vbNewLine).First & "...") _node.ToolTipText = _verse[code]...
I need to grab the TreeNode that's selected when someone right-clicks on it. The TreeView.selectedNode() returns the top-most node, and disregards the child nodes.
I'm confused regarding the MS examples for inheriting a treenode. I have created the following class to allow an addtion description field on the treenode:-
I have some code that allows me to drag a treenode into a listbox and then drag it back into the treeview as needed. When I drag a node out of the treeview, the node is removed from the treeview. When I drag it back, I need the node to be inserted into the same parent node/position it came from. I think I can save the node's FullPath property before removing it from the tree, then decipher it again when I re-add it but am looking for a cleaner way
I start with VB 2010 since a short time.I need to check in a Treeview if a node has children or not.In VB 6 there was the property clildren that allow to understand this.
I built a treenode to be populated from my network drives, from this treeview I would like to populate another treeview to show the files when the first one is selected. For example, if the user were to click on the c:TestFolder then the second treeview would show the TestFolder, all sub folders and files.
Below is my code: Imports System Imports System.IO Public Class F_Treeview_Demo Public IsSomethingChecked As Boolean = False Private fbIgnoreClick As Boolean = False [Code] .....
i have a prob that i have a gridview on the parent window. when i open a child window using showmodaldialog, i enter some data in the textboxes. now when i close my child window i want to display the text entered by me in the grid. i want to know how can i access the grid in child window
I extended treeview, treenode, and nodetype so I could have custom nodes. Certain nodes have image buttons on them allowing them to add a child node or delete the node. I can't handle any of the events from my buttons.Public Class ContentTreeView Inherits TreeView Public Event OnAddChild(ByVal sender As Object, ByVal e As EventArgs) Public Event OnDelete(ByVal sender As Object, ByVal e As EventArgs)
I want to do a form that can let user manual add in or delete tree node.When they add in, they can set the name and file path.Then it will store in oracle database.Each time my form run it will go through my database then execute all node from there.
I dunno this can work or not..I want to do a form that can let user manual add in or delete tree node.When they add in, they can set the name and file path.
It seems that Visual Studio is using a older verion of the System.Windows.Forms DLL.
When I instantiate a instance of the TreeNode object it doesn't have the "value" property. Right now my version of Sytem.Windows.Forms is listed as 2.0.0.0 and it's being pulled from the Microsoft.NETFrameworkv2.0.50727 folder.
I've installed all of the current .NET framework service packs....
Is there something else that I need to do so that the I load the most current version of this object?
So I have a TreeView that starts off empty. Sequence of events is as follows: Add a new root node. Code makes the label edit box pop up immediately, and I give it a name. Add a new subnode to that root node. Add a new root node, after the first one. The label edit box pops up, and I give it a name.
The second root node takes on its new name, but so does the subnode added in step #2. Now, it's not really the subnode's text; if I examine that TreeNode in the debugger, it has the proper text for a subnode. But that text that was entered into the root node sticks around through expanding and collapsing its parent node, until something else happens and I need to rebuild the tree.
I'm building the tree in kind of an odd way - removing all root nodes from the parent, all child nodes from the root, updating all the tags and text, creating new nodes, then re-adding the nodes to their parents - but I've checked, and the proper text is being associated with the proper node. The TreeNode that is showing the wrong text has only ever modeled the one object, never had anything else in its Text property, and has its text set back to the right value ("untitled action") right before being re-added to its parent node.
All I can think of for a culprit is the code for the label editing box, which is based on an MSDN sample: Private Sub EditSelectedCategoryName() If Not ActionList.SelectedNode.IsEditing Then ActionList.LabelEdit = True ActionList.SelectedNode.BeginEdit() [Code] .....
EditSelectedCategoryName is called by a context menu item's Click event, right after the new root node is added and made the selected node. The DisplayName setter in the AfterLabelEdit event handler is what triggers another chain of events that rebuilds the tree. So am I screwing up some internal structure of the TreeView by altering its contents in the AfterLabelEdit event?
I have a recursive function wich objective is scan an structure and represent that structure with treenodes. Inside my function depends the structure I'll have to create another treenode inside my treenode or just create a node. My problem is that I don't know how to remember my treenode position when I have to call my function again.
If strTop.TextString.ToUpper = "DMN" Then gcTreeno.Nodes.Add("Node") Else Dim perf As New TreeNode gcTreeno.Nodes.Add(perf) End If
if i would like to write next time a node into perf, how i could do it?
Items in the child node seem to replicate themselves everytime when expanded from a collapsed state. I think the problem is that the memory needs to be cleared before I expand.[code]...
