Populating grid in C# 3.5

Question

Yesterday i installed C# 3.5 and today when read topic here of "Accessing Google Spreadsheets with C# using Google Data API", and decided to try it out.

So i decided to write a example, that: 1) get data feed of first Worksheet of first Spreadsheet, that name contains string segment that user inserted 2) fill grid with data

Well i got to part, fill 2 dimensional array or lists of list with spreadsheet value data. I am stuck at finding a control to put data into, and dynamically generating it, as i don't know rows or columns of worksheet beforehand.

My intuition says, i could just change List> with Dataset, and start trying out different controls, that IntelliSense throws at me. I am aware that i should read a book first, but i was to impatient not try it out first.

Xaml

<DockPanel Background="LightSteelBlue">

    <!-- Standard input -->
    <DockPanel DockPanel.Dock="Top" Margin="5">
        <TextBlock Margin="10,0,5,0" VerticalAlignment="Center">Username:</TextBlock>
        <TextBox x:Name="username" Width="120" Padding="5,0,5,0" Text="username@gmail.com" />
        <TextBlock Margin="10,0,5,0" VerticalAlignment="Center">Password:</TextBlock>
        <TextBox x:Name="password" Width="120" Padding="5,0,5,0" Text="password" />
        <TextBlock Margin="10,0,5,0" VerticalAlignment="Center">Workbook:</TextBlock>
        <TextBox x:Name="workbookname" Width="120" Padding="5,0,5,0" Text="name" />
        <Button x:Name="getData" Margin="5,0,0,0" Padding="5,0,5,0" Content="Get _Data" Click="getData_Click" />
    </DockPanel>

    <!-- Grid display -->
    <ListBox Name="lb2"/>

</DockPanel>

Answer 1

I've used this from the WPFToolkit:

<my:DataGrid Margin="0,29,0,0" Name="dataGridView" xmlns:my="http://schemas.microsoft.com/wpf/2008/toolkit" AlternatingRowBackground="AliceBlue" ItemsSource="{Binding Path=.}" CanUserResizeRows="False" ClipboardCopyMode="IncludeHeader" IsReadOnly="True" IsTabStop="True" AutoGeneratedColumns="dataGridView_AutoGeneratedColumns" />

With some code behind to populate it:

private DataTable dataTable;

public Constructor()
{
    ....
    this.dataTable = new DataTable();

    dataGridView.DataContext = dataTable;
    ....
}
