I have a TreeView in my application,while page loaded TreeNodes Id are Unique.But while me to use for RenderControl Method TreeNodes Id are not unique. Why TreeNodes Id are not Unique?

Is GUID (globally unique identifier) really unique, or it can be duplicate.
System.Guid.NewGuid().ToString()
I've managed to render TreeView using custom made Hierarchical Datasource based on Linq queries on self referencing table. Rendered output looks well but... Every Node in NodeCollection has the same index = 0. Therefore when I click on any collapse button - the whole tree Collapses. In generated html every node has the same id = MainContent_TreeView1n0 I suppose n0 should increment to n1 n2 n3 and so on.
View 5 RepliesThis thread is basically a continuation from my last post. I have a website that uses a TreeView Control. Each TreeNode represents a virtual directory and I wish for the user to be able to create a new Node/Virtual Directory. This site is for family photos. Each family member has their own node with a Child Node called "Albums". Within this "Albums" node, a family member can have as many Nodes/Virtual Directory as they want with each Node/Virtual Directory containing images.Each Virtual Directory path is stored in a Database. So essentially, I'm trying to create my own photo album. My question is....how do I allow a user to create a new Node/Virtual Directory (they don't know that a VD is being created...only a Node).

I have a nested masterpage and in the childpage of the second master I have a treeview. Now I want to change appearence of the nodes in it (like the color), and I´m not able to do that. It doesn´t say anywhere if there´s a section of the css stylesheet that´s being applied.
Is there any way i can make all the nodes of the treeview checked by default other than looping through the nodes and setting each node property Checked=true; I dont want to unnecassary loop through the node collection to set each node property. There should be easy way of doing this by setting simple property for the entire treeview. Oh i am using the RadTreeView, I dont have the

View 1 RepliesI have this code:
Code:
Dim obj1 As New TreeNode
obj1.Value = 1
obj1.Text = "Level" & obj1.Value
Dim obj2 As New TreeNode
obj2.Value = 2
obj2.Text = "Level" & obj2.Value
[Code]...
Can I somehow create a function that creates the nodes instead of I need to make Dim ... each time? If I have 300 nodes this is not a good solution.
I have tried something like this but it doesn't work:
Code:
Function CreateObj(ByVal no As Integer, ByVal name As String, ByVal obj As TreeNode) As TreeNode
obj.Text = "Level" & no
obj.Value = no
treeview1.Nodes.Add(obj)
Return obj
End Function

View 4 RepliesThis form includes some textboxes for user input. Each user will have a different amount of input to provide and there's no way to predict how many textboxes to create at design time. I have a button for adding a new textbox. The click event is here below (I chose to limit random to 10 just for my testing):
[Code]....
This creates the same textbox over and over again with a different ID. I need it to add a new textbox with each click.
I want to generate a unique random number everytime a user submits a form. As the form is submited the data of the form should be placed in a database and a unique random number should be generated so that the user can later use this unique random number to reterieve his details from the database that refer to his unique random id. The unique random number should be atleast 9 digits long.
View 5 RepliesI have a webform that writes respondent info to a sql data base. I want to send a email campaign and use a unique identifier so that if
1. joe clicks on his link http://www.test1.aspx?209
2. tim clicks on his link http://www.test1.aspx?603
that when they click the form submit the data gets written into the correct row where 209 and 603 are their respondent numbers already in the data base. This is my first attempt using c# and I couldn't find anything in my books about it.
I have an easy problem for the experts here...been a few years since my last development work. I have an appl that will track complaints. When an administrator logs in, they go to the main admin.page. From there, they can create a new complaint record-here is where i'm stuck and am looking for a better way. When the admin loads the create.aspx page. i need a way go generate a unique number that i can insert into the db. What is the best way to generate the number...i don't care whether it's numerical or combo, just unique and durning postback the number does not change...the number will be given out as a reference back to the complaint... This seems pretty standard but I can't think of a way that will not duplicate numbers and am looking for best practice with low
View 3 RepliesMy requirement is when user clicks Add button, the textbox value must be added to listbox. The following code works well
[Code]....
But i don't want the user to add same text multiple times. The listbox items(Text) must be unique.
The below is from the watch window in vs2010.

I use a form variable to sore USER_ID and pass it in various sub and function at the same page.
Is form variable unique for each user? That is, if more than one user open this page at same time, will app cause problem?
I have a UserControl (basically a custom menu) that has some properties on it that I store in the view state. My pages may have multiple instances of this control, so to keep the values unique in the ViewState I concat my names with the control's UniqueId. However, when the properties are set the UniqueId does not exist yet, it returns the control's ID, in the case below, mnuFormNote. So then later when they are read it doesn't return the correct value because later the UniqueID is set so it attempts to read from a different ViewState location.
So, my question is am I doing something wrong or just missing something? If not, is there a way around this?
[Code]....
So when the page loads, and ShowEvents is set to False the property set actually does this: ViewState("mnuFormNoteShowEvents") = False. But later, when I attempt to Get the ShowEvents value it is doing this: ViewState("ctl00$ctl00$mstrContent$iepointMasterContent$dlForms$ctl00$dlStudentForms$ctl00$mnuFormNoteShowEvents"), which is nothing, so it returns the default of True. I need this value to be unique.
