I had a similar question for DatagridComboboxColumn but that shown me how to use the .itemsource to bind to an array outside of the datagrid. I am having a problem trying to bind to the collection that the datagrid is bound to at runtime.I have included a working test program for how I am approaching this.
Class MainWindow
Dim ServerInfoArray As List(Of ServerInfo) = New List(Of ServerInfo)
Private Sub GetInfo(ByVal list As List(Of String))
[code]....
I can get all Strings and Boolean to bind.I do not know how I can bind this DataGridComboBoxColumn to the list of attached on the property. I cannot use XAML as I need to do this at runtime.

I have a datagrid in my vb.net 4.0 wpf project. I have seen many examples in XAML on how to bind a DataGridComboBoxColumn however I need to do this in code as I have auto-generating columns. I switch the datagridbinding source to multiple data sets. Inside some of these custom classes are a couple lists. I can get text and checkboxes to auto-generate correctly. When it comes across my array (I have tried many different kinds) I just see a textboxcolumn with the words (Collection) in it.
For instance - One screen I am grabbing system information on WMI calls. One of the calls returns all IP addresses on the server (We can have up to 8 IP addresses) I do not want a column per IP address. I would like to include a list of those into the datagrid so you can drop down and see them.
Sample Code
Imports System.Collections.ObjectModel
Class MainWindow
Dim ServerInfoArray As ObservableCollection(Of ServerInfo) = New ObservableCollection(Of ServerInfo)
[code]....

I'm trying to bind a dataset to a datagrid. I've found many examples online... all look similar to below. My problem is that the bind seems to work, but nothing shows on the datagrid. It's blank. Both rowcounts in the message boxes display the correct number of rows for both the dataset and datagrid. Does something need to be initialized in the datagrid properties?

I'm using a the WPF DataGrid from the wpf toolkit and a TimePicker from AvalonControlsLibrary to insert a collection of TimeSpans. My problem is that bindings are not working inside the DataGrid, and I have no clue of why this isn't working.Here is my setup:
I have the following XAML:
<Window x:Class="TestMainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:wpf="http://schemas.microsoft.com/wpf/2008/toolkit" xmlns:a="http://schemas.AvalonControls/AvalonControlsLibrary/Controls" SizeToContent="WidthAndHeight" MinHeight="250" MinWidth="300">
<Grid>
[code].....
EDIT 1: I forgot to mention that the binding to SelectedTime TimeSpan works as expected. The problem are the bindings inside the DataGrid.

I have the following datagrid:
<asp:DataGrid runat="server" ID="gastosReembolsables" ShowFooter="True" AutoGenerateColumns="False">
<AlternatingItemStyle CssClass="DATAitem2"></AlternatingItemStyle>
<ItemStyle CssClass="DATAitem1"></ItemStyle>
<HeaderStyle CssClass="DATAheader"></HeaderStyle>
<FooterStyle CssClass="DATAitem1"></FooterStyle>
<Columns>
[Code]...
all bindings work except the ones in the validation controls for the itemtemplate of the last column (they are passed as text to the web page). Why is this happening? is it even possible to do what I'm trying to do?

I have a datagridview bound to a datatable. I want replace one of the cells with a combo box and bind that combobox to one of the columns in the datatable. I have been able to replace the cell OK but currently have two issues I have not been able to resolve.
1. When I add items to the drop down (items.add ("Yes")...) they don't appear in the drop down box.
2. I can't figure out the syntax to bind a particular column in my datatable to the newColumn(combobox) in the datagridview.
dbConnection = New OleDbConnection
cmdCommand = New OleDbCommand

I'm having trouble with some Silverlight functionality. My goal is to get some data from the database and display it in my grid. Sounds simple, however, there are 7 columns that are always going to be there.
The rest of the columns depends on the account. There could be 2 (called Actions) associated with a certain account, compared to another account that could have 5, and the action names can be completely different.
I have successfully been able to return a list of all the possible actions for the given account, and then adding the columns to the grid in the code bihind(VB), and I can bind my data to the grid for all the columns that are already known. The way I store the item's actions, is a Property of type List. My problem is finding a way to iterate through the actions list of the Item object in order to bind those actions to the grid.

I have a datagridview that is populated using an oledbconnection:
Private Sub FileSpecs_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim cn As OleDbConnection = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & My.Settings.DBLocation & ";")Dim cmd As OleDbCommand = New OleDbCommand("SELECT specFieldno AS [Field No],specFieldName AS [Field Name], specFieldType FROM fileSpecs WHERE ClientNo='" & ClientSetup.clientNo.Text & "' AND direction=" & ClientSetup.fileDir, cn)
[Code]...
The problem I now face is that the 'index' value of the combobox item for each row is in the field specFieldType which is populated into the datagrid.I need to be able to set the value of the ComboBox for each row when the form is opened, and also be able to save the index value of each row selection if any changes are made/saved.

I use objectbinding to display client data in a datagridview. The datagridview also contains a counry-column allowing the user to choose the country of the client.Unfortunately, databinding of comboboxcolumn does not seem to work if an own business class is used. Using a simple collection instead works well.Copy the sample code into a new windows project and the programm runs fine. Then comment and uncomment the two lines with "XXX" and the code will fail. Why and does anybody know how to make the sample code work by using the business object class(variable named "newClientListVariable" in the sample)? [code]

I started programming in VBA, then graduated to VB6, and I am now using VB.NET 2008 Express.I have read, in the various posts, that I should keep Option Explicit and Option Strict both on, in order that I use correct VB.NET code and not VB6.I am trying to do that but am totally confused with the results of one of my programmes that was running perfectly with Option Strict off, but now advises:Option Strict On disallows late binding. To me it appears that I am using early binding, but to be honest I am not clear on the binding situation. I have checked through a number of google items, and a number of this Forum's items without seeing the light.[code]
