I am trying to put a series of comboboxes in a grid and then I bind them to a list. For some reason unknown to me when I click the open button on the combobox nothing happens. If I move a comobobox outside the grid it opens just fine. Can someone please tell me what I am doing wrong here. It has to be something stupid because I've used comoboxes before just fine.
Here is my xaml:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<GroupBox Header="Download Critera" Margin="70,30" Name="groupBox1" Grid.RowSpan="2">
<Grid Height="Auto" Name="grid1" Width="Auto" Margin="0" IsHitTestVisible="False">
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
<RowDefinition />
<RowDefinition />
<RowDefinition />
<RowDefinition />
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Row="1" Margin="10,5,5,5" Name="textBlock1" Text="A:" Foreground="Black" VerticalAlignment="Center" FontSize="14" FontWeight="Bold" />
<TextBlock Grid.Row="2" Margin="10,5,5,5" Name="textBlock2" Text="B:" Foreground="Black" VerticalAlignment="Center" FontWeight="Bold" />
<TextBlock Grid.Row="3" Margin="10,5,5,5" Name="textBlock3" Text="C:" Foreground="Black" VerticalAlignment="Center" FontWeight="Bold" />
<TextBlock Grid.Row="4" Margin="10,5,5,5" Name="textBlock4" Foreground="Black" Text="D:" VerticalAlignment="Center" FontWeight="Bold" />
<TextBlock Grid.Row="5" Margin="10,5,5,5" Name="textBlock5" Text="E:" Foreground="Black" TextAlignment="Left" VerticalAlignment="Center" FontWeight="Bold" />
<ComboBox x:Name="cb1"
Grid.Column="1" Grid.Row="1"
Margin="5" MaxDropDownHeight="100"
ItemsSource="{Binding Projects}"/>
<ComboBox x:Name="cb2"
Grid.Column="1" Grid.Row="2"
Margin="5" MaxDropDownHeight="100"
ItemsSource="{Binding Projects}"/>
<ComboBox x:Name="cb3"
Grid.Column="1" Grid.Row="3"
Margin="5" MaxDropDownHeight="100"
ItemsSource="{Binding Projects}"/>
<ComboBox x:Name="cb4"
Grid.Column="1" Grid.Row="4"
Margin="5" MaxDropDownHeight="100"
ItemsSource="{Binding Projects}"/>
<ComboBox x:Name="cb5"
Grid.Column="1" Grid.Row="5"
Margin="5" MaxDropDownHeight="100"
ItemsSource="{Binding Projects}"/>
</Grid>
</GroupBox>
