Forms :: Find A Method Of Looping Through A Listbox And Retrieving The Index Number And Values?
Mar 24, 2010I need to find a method of looping through a listbox and retrieving the index number and values - quite straightforward in asp, but turning out to be something of a nightmare in winforms!Here is the scenario - The user can add values in a textbox, that are in turn added to a DataTable that gives it a unique ID and a row number, this is then bound to the listbox. The user can then move the items up or down the list by adjusting the row number in the datatable and rebinding to the listbox..
The problem that I am hitting is when the user needs to delete an item -the first part is easy - delete from the DataTable and rebind to the listbox. The bit where I hit the proverbial brick wall is needing to loop through the listbox rows and getting both the index number and the ValueMember - that way I can change the row numbers in the DataTable based on the index number against the ID number.

Treeview - Check All Child Nodes On Checking Parent Node?
Jul 6, 2011I was wondering how I would go about placing a check in the checkboxes for each child node of a parent node in a TreeView control, if I was to check the parent node.
For example:
Parent 1Child 1
Child 2
Child 3
If I was to check "Parent 1" how would I be able to make that event place a checkbox beside all of the child nodes of "Parent 1"? (Child1, 2, and 3.)
XML Node Search Jump - Xml Reader Reads All Child Nodes
Dec 16, 2009[Code] my problem is if i search the class node with the name attribute of value "IT MAJEL 03", the xml reader reads through the first class which is "IT MAJEL 04" and read all of its child nodes(which i think is very awkward. why continue reading to its child nodes if the class name you're looking does not even match). is there another way to actually jump the reader of the xml node to the next xml node of the same level?
I mean if I search the class named "IT MAJEL 03", the reader should jump to the next same level element it does not match the query. It should skip reading the "IT Majel 04" child nodes. what I want to achieve here is I want to save nanoseconds of computing.

View 3 RepliesAsp.net - Find TreeView Node By Value?
Sep 15, 2011All 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?
