Mouse scroll not working in a scroll viewer with a wpf datagrid and additional UI elements
- by paladugu457
I am trying to figure out how to get the mouse scroll working on a wpf window with a scrollviewer and a datagrid within it. The WPF and C# code is below
<ScrollViewer HorizontalScrollBarVisibility="Disabled" VerticalScrollBarVisibility="Auto">
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid Grid.Row="0">
<Border Name="DataGridBorder" BorderThickness="2" Margin="1" CornerRadius="4" BorderBrush="#FF080757">
<dg:DataGrid AutoGenerateColumns="False" Name="ValuesDataGrid"
BorderThickness="0" CanUserResizeColumns="True" FontWeight="Bold" HorizontalScrollBarVisibility="Auto"
CanUserReorderColumns="False" IsReadOnly="True" IsTextSearchEnabled="True" AlternationCount="2"
SelectionMode="Extended" GridLinesVisibility="All"
HeadersVisibility="Column" CanUserAddRows="False" CanUserDeleteRows="False" CanUserResizeRows="False" CanUserSortColumns="False"
RowDetailsVisibilityMode="Collapsed" SelectedIndex="0"
RowStyle="{StaticResource CognitiDataGridRowStyle}"
>
<dg:DataGrid.Columns>
<dg:DataGridTemplateColumn Header="Title" >
<dg:DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" >
<TextBlock HorizontalAlignment="Left" VerticalAlignment="Center" Text="{Binding Path=Name}" FontWeight="Normal" />
</StackPanel>
</DataTemplate>
</dg:DataGridTemplateColumn.CellTemplate>
</dg:DataGridTemplateColumn>
</dg:DataGrid.Columns>
</dg:DataGrid>
</Border>
</Grid>
<Button Grid.Row="1" Height="90" >hello world</Button>
</Grid>
</ScrollViewer>
and the C# code is as follows
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
initialize();
}
public void initialize()
{
ObservableCollection<MyObject> testList = new ObservableCollection<MyObject>();
for (int i = 0; i < 20; i++)
{
MyObject my = new MyObject("jack " + i);
testList.Add(my);
}
ValuesDataGrid.ItemsSource = testList;
}
}
public class MyObject
{
public string Name { get; set; }
public MyObject(string name)
{
Name = name;
}
}
The problem i am facing is that when using the mouse to scroll, it works fine when it is over the button but as soon as i move the mouse pointer over the grid and try to scroll, nothing happens. I am able to move the scrollbar of the scrollviewer directly though. I am still a wpf novice so any help on how to get the mouse scroll to work over the datagrid would be appreciated. I am guessing there should be a pretty easy solution for this but I havent been able to figure it out
