I have a client who needs a database to display products.He would like to have the product attributes in the rows headers and new records added to the columns. I have a collection of a class that would contain the products and am binding it as a data source. however all I can get is the attributes to show up in the columns and the records to show up in the rows.

View 2 RepliesI bring data in from an access database using a sql query and then assign the data to a datagrid view. When i try to delete data from the table, it is removed from the datagrid, but the change is not showing up in the actual table.As a second question, is there a way to tag the specific row and send that back to the actual database for deletion? The way i have it set now, i think would delete all instances where digit, day, and office match, instead of just the selected record.

i have datagridview populated with stock code, name and description.And i have docked my datagridview to the bottom. so whenever the form is resized, the bottom section will be occupied completely with the datagridview.But i want to display one extra empty column and multiple empty rows to completely fill in the datagridview.The extra empty column width will be adjusted to the right end side of datagridview.And the no of empty rows will be generated based on how many is required to fill up to the bottomSo that i can create datagridview with full column and row even though some columns or rows are empty.

View 4 RepliesI'm fairly new to VB.net and WPF (and programming in general), so please bear with me. I'm attempting to write a useful database app for my business as a learning project. I did a draft in WinForms, referring to the (very good) Murach book, but am now trying to re-write it with a WPF UI and cleaner code.
I think I understand the basics of WPF binding, but am tearing my hair out trying to find a simple way of binding to parent details - which I would have thought was a very basic scenario, but I can't find anything on it. For example, let's say I havea 'Customers' table with CustomerID, Name, various contact details and then foreign keys CityID and GroupID;
[Code]...
And then just moving to the first record (as there will only be one). Is this a normal method of looking up a customer? I could also use this method by getting the foreign keys from my customer row and filling the different tables in the dataset all using parameterised queries, then just binding to each table separately - but again, seems very messy.
I'me getting real dumb with this one....I have this class:
Public Class whatever
Public id as string
Public name as string
public date as string
end class
Wich I use with this code:
dim personlist as new arraylist
dim person as new whatever
person.id="1"[code].....
and then i repeat so that i can fill my arraylist with all the information that I want to show in my gridview.The problem is this:
gridview1.datasource = personlist
gridview1.databind()
When executing, I get an error saying :
The data source for GridView with id 'gdpersonlist' did not have any properties or attributes from which to generate columns. Ensure that your data source has content.

I am novice in WPF. I have a wpftoolkit datagrid where i am using a combo box as datagridcombox column. I am using a observable collection of Codes for binding the combo box. Below is the collection and its class...
#Region "Class & Coll"
Public Class CodesColl
Inherits ObservableCollection(Of Codes)

Unable to display the codes in dropdown. Somehow i manged to do so but it disappears after loosing focus from the combobox. Unable to retrive the description on its selection change as , i am unable to find the event too.
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'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 an ArrayList that are separated by the pipe:
