Making A ScrollBar Go To Selected Record In TreeView ASP.Net
Feb 26, 2010
I have a treeview control that gets populated at runtime with a pyramid of employee names. I put the css scrollbar on the view by putting overflow: auto" in the tag where the treeview is located. The users are now asking me to to have the scrollbar go down in the treeview where a treeview item is selected.How do I make a scroll bar to go to a place where the treeview has been selected?[code]
I 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 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.
I 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.
So with the stock Textbox, I set the Scrollbars property to Vertical. This is great if the text in my box never changes; I can scroll up and down while the box sits still. If I'm running a background operation that logs output to the box though, the scrollbar resets itself to the top every time I append text to the box.
I know I can set the Textbox.Selection property (or use the Select method) to reposition the carat in the textbox, make note of that position in a variable, then append text, reset the carat, and use the ScrollToCarat method to reposition the scrollbar where it belongs. That's a really (ridiculously) long way around. Anybody know if there's another/better way of holding the scrollbar position, short of actually building a custom control (or using a Textbox and a separate Scrollbar)? It never hurts to try. In a worst case scenario, you'll learn from it.
I have a treeview with four levels; parent, child, grandchild, great-grandchild. My selectednode is at the grandchild level. What I'm trying to do is to create a new "Treeview" at the grandchild - NO, I dont wnat to create a new node to the "selectednode" (grandchild). So it should be somelike 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"
[URL] for example...when i click the folder in the TreeView, the ListView will display all the items in the folder....but how to write the coding
coding for TreeView Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load GetFolders(Nothing, "c:users", TreeView1) End Sub
for 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)
for example...when i click the folder in the TreeView, the ListView will display all the items in the folder....but how to write the codingcoding for TreeView
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load GetFolders(Nothing, "c:users", TreeView1)
The TreeView control in my application was working fine until i added *small* icons, now whenever i try to open a node the selected node and the one above flickers...
I have a treeview and if I click on another control the hightlight disappears so I set the HideSelection to false and now the highlight row changes to a really light gray. Is there a way to have it still as dark blue. The reason being is because the user is clicking on a row in a grid and dropping it on the treeview and I need it to be clear that it will add it to the selected node which needs to be clear.
If you have a saved string or value in your database. How can you open this that it is selected in a treeview? i mean when you click for example a commandbutton (Open my data)
I have a treeview on this page of which each node has and Id and value. on selected node change event, I want to change the text of repeater selected node. I am writing code like this:
Protected Sub TreeView1_SelectedNodeChanged(sender As Object, e As System.EventArgs) Handles TreeView1.SelectedNodeChanged Dim EmployeeRepeater As Repeater = CType(Me.Form.Controls(1).FindControl("Repeater1"), Repeater) Dim EmployeeRepeaterItem As RepeaterItem
[code]....
But It is not chagging MyLabel text. How to fix it ? Both treeview and repeater are populated in !Page.Ispostback 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 am trying to make an address book and need help. I am in the middle of making a search function for the program and I've got that working fine. What I would like to do is take the row that is selected from the search results and make that the selected entry for the main form. To explain what I mean I will include pics..
This is the form I'm having problems with. As you can see I've created a tab interface which is working. There are five text boxes on it which are binded to the Staff table in the database. When the tab is changed, the binding is changed to a new field. However, unfortunately, when a new record is selected, the data bindings do not update, and instead, the first record is always being used. We suspect the problem may be coming from the fact that there is code to unbind from the text box and rebind it again. This is the code I'm talking about...
Private Sub TabCheck() If TabState = 1 Then pnlTabs.BackgroundImage = My.Resources.tabs1 txtBox1.Visible = True txtBox2.Visible = True [Code] .....

I'm currently developing a application in VB.Net 2008. I'm using the DataGridView to display my data on the form and I have stored all the records in MS SQL. I have a EDIT button on the module and I need to know how can I populate a selected record into the textboxes from the DataGridView to be edited.
