I have a hashtable that stores sports players: key = jersey number, value = an array of information...and what I am trying to do is put this information into combobox (but only showing a certain array elements), so for example say this was the information stored in the hashtable:
(key,{value})
"01",{"john smith","125lbs","qb"}
"02",{"john doe","205lbs","rb"}
so what I have done is created an arraylist that will store the items in the combobox.but my problem happends when I try to loop through the array from the hashtable values.
(playerlisting is the hashtable)
Dim playerlist As New ArrayList
[code]....
The above works, however since it's a foreach loop I cannot specify which array indexes I want to add onto the "listitem" string.
Dim arr As Array = CType(item.Value, Array)
For i = 0 To arr.Length - 1
listitem += arr(i) & " "
Next
But, when I try a simple forloop instead I get a "late binding" error with the 3rd line. Even when I cast the arr(i) as a string I get the error. What needs to be changed?

I am trying to create a basic webpage that will check a column of a database table to see if a "UPC Code" is taken already, to prevent duplicate use. I'm fairly new at .NET programming, but have built asp pages before. I'm just stumped :/
I have a textbox that a user can type in a number. The page successfully checks to see if the textbox is blank and reports the error, and if there is a value, it's supposed to bind that textbox number to a gridview to see which Item# it's associated with. But for some reason, my code is not binding the value of the textbox to the gridview.
Code:
<%@ Page Title="Home Page" Language="vb" MasterPageFile="~/Site.Master" AutoEventWireup="false"
CodeBehind="Default.aspx.vb" Inherits="UPC_Checker._Default" %>
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
</asp:Content>

I have a DataGridView that is bound to a BindingSource. Below this are a group of textboxes that are associated with each column in the DGV. I tried to bind the textboxes to the BindingSource but realized their was no DataSource property for the textboxes. How can I bind them?

I have the following code where I'm trying to bind a datarow to a textbox.
Me.TierNameText.DataBindings.Add("Text", Me.m_TierRecord, "tier_name") Problem is, when the form is displayed no text is shown in the textbox.
This code runs before I call the form's ShowDialog method. I stepped through the code to make sure the datarow has data, and indeed it does.
I rarely use databinding but thought I'd try it this time.

I have been searching for an answer for this for almost a week now, and I can't seem to find a way to do this. I would think it is a relatively simple thing...
I have a ListView, and one GridViewColumn contains TextBox items. I want to put a Label right underneath the ListView, and fill it with the sum of the items in all the TextBoxes. Whenever someone changes a value in any of the TextBoxes, the sum should change, too.[code]...

I am running Windows 7 and have an application that has a textbox bound to a Property in a Custom Class that Implements IEnumerable.When I call Raise Event to update the textbox it will only work the first time.However, the application works on every other OS I have tested on (XP, Vista). Also if my custom class does not implement IEnumerable it works correctly.Is this a bug? Am I doing something wrongform with a textbox and a button. The Textbox is bound to the Total Property in the class.

Im having some wierd behavior on a bound form in vb.net 2008. I have setup a client form, with another tab that has contacts for that client. the contacts tab has a binding navigator at the bottom, so the user can move amongst the contacts. all fields on that form are bound to a bindingsource called bsContact, using a table adapter called "ContactTableAdapter"
if i have a contact already saved, and want to modify the contact info, the form binding doesn't seem to recognize that i have changed the value of a textbox on that contact.i would think that if a textbox is bound to a bindingsource, then if the value of that textbox changes, the bindingsource would know about it, but it doesn't. The dataset.HasChanges returns false, and my save wont happen. (see code)so, when i hit the movenext on the bindingnavigator, it changes to record 2...i change a value on a textbox...i hit the save button on my form....no update will happen.
Update: I noticed that if i am on the tab with the multiple contacts, and i change a textbox on the form, then i MOVE TO ANOTHER RECORD, then the dataset recognizes that there was a change, and the update happens. Why doesn't the textbox immediately notify the dataset that a change is happening?

I have one DataGridView named dgv.dgv is pretty much a plain gridview. No bounded data. No columns added. It's basically empty.I also have one DataTable named dt.I add rows and columns manually into dt.
dt.Columns.Add(New DataColumn("TexBox", GetType(String)))
dr = dt.NewRow()
dr("TextBox") = String.Empty
dt.Rows.Add(dr)
I then simply set dgv datasource into dt.
dgv.DataSource = dt
dgv.Refresh()
I then set the value for this particular cell.
dgv.Item(0,0).Value = "xxx"
Now when I run and execute all those commands. I happen to retrieve the gridview with that value indeed. The "xxx" cell appeared and currently it's uneditable.What I want to achieve is:Allow this "xxx" cell to be editable. Preferrably if it can be inserted into a TextBox control inside the cell.

I Have a question about binding (pageID + PermissionID) to a checkbox/ checkboxlist, without using a textbox or any other tool. The thing is, i'm working on something just for exploration is it possible to have multiple checkboxes all bind to a different pageID but all have same permission. (lets say the permission is view-only) So when some checks a checkbox with ID 1, ,5,9,19,56 he gets view permission to those pages. when he uncheckes then they get deleted.

I need to bind a textblock.text property to a single element in an observable collection, or array element, and have the text update using the INotifyPropertyChanged or INotifyCollectionChanged, whichever is best.
Most examples describe ways to bind listboxes or other list views to entire collections, but my application needs to update several textblocks on a screen depending on notification of a change in one or more elements of an array.
textblock1.Text = MyArray(0)...
textblock2.Text = MyArray(1)...
textblock3.Text = MyArray(2)...
textblock4.Text = MyArray(3)...
Is it possible to bind a single textblock to a single array element? Is it possible to get notification of the proper type that will update one or more of the textblocks if any assigned element changes?

I am binding a textbox's text value setting to my a variable in my configuration file. I only consider the input from this textbox to be valid if it's an integer number bigger than 1. Right now what I was doing is letting the user write whatever he wanted in the box, and I'd only let him save the settings after calling a validation function. The problem seems to be that my binding variable in the Settings class seems to be being updated as soon as the textbox is being edited, and that's a behaviour i'd like to skip. How can I do this?
