Good afternoon.
I have an WPF application with a grid consisting of two rows and two columns, containing players.
My problem is that I would change at runtime the layout of the grid. Such as leaving only one row and one column or two rows with a column...
From the code behind, I haven´t the ability to access or the colspan rowSpan ...
It is possible to do this functionality with the grid? or there is another control that allows me to change the arrangement of the players at runtime?
Thank you very much in advance
<Grid Name="MainGrid">
<Grid.RowDefinitions >
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions >
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<dbf:DbfPlayerUserControl x:Name="player1" Grid.Column="0" Grid.Row="0" ></dbf:DbfPlayerUserControl>
<dbf:DbfPlayerUserControl x:Name="player2" Grid.Column="1" Grid.Row="0" ></dbf:DbfPlayerUserControl>
<dbf:DbfPlayerUserControl x:Name="player3" Grid.Column="0" Grid.Row="1" ></dbf:DbfPlayerUserControl>
<dbf:DbfPlayerUserControl x:Name="player4" Grid.Column="1" Grid.Row="1" ></dbf:DbfPlayerUserControl>
</Grid>

You mean something like:
player1.SetValue(Grid.ColumnProperty,1);
|
|
|
|
|
myGrid.SetValue(Grid.RowSpanProperty, intSpan);
The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

I think it might be a solution

Infragistics provides some files that help export a datagrid to excel.

MSDN has an article[^].

Hi

Do you know where to find opensource projects in silverlight or wpf please?
Thanks
|
|
|
|
|
Ooh. Let's see. Codeplex. Code Project. Google Code. Source Forge.
|
|
|
|

I think opensource refers to projects which are free for anyone to download and use.
I have been searching for such a project i.e. a complete project which can I can go through to understand and learn...
I have searched already in the sites you mentioned but I have not found a complete project. The ones I have found are all to do with single controls in each project.
Thanks anyway, I will continue searching...

The awesome Karl Shifflett produced a great sample called BBQ Shack[^]. There is so much to learn in there.

Hello!
I'm testing WPF Toolkit DataGrid to display 2000-5000 rows.
I try to apply my control template for WPF Toolkit DataGrid.
VirtualizingStackPanel.IsVirtualizing set in True.
<Style x:Key="{x:Type DataGrid}" TargetType="{x:Type DataGrid}">
<Setter Property="MinRowHeight" Value="20"/>
<Setter Property="BorderThickness" Value="1" />
<Setter Property="SelectionUnit" Value="FullRow"/>
<Setter Property="IsReadOnly" Value="False"/>
<Setter Property="ScrollViewer.CanContentScroll" Value="True"/>
<Setter Property="ScrollViewer.IsDeferredScrollingEnabled" Value="True"/>
<Setter Property="VirtualizingStackPanel.IsVirtualizing" Value="True"/>
<Setter Property="VirtualizingStackPanel.VirtualizationMode" Value="Recycling"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DataGrid}">
<Border Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"
SnapsToDevicePixels="True"
Padding="{TemplateBinding Padding}">
<ScrollViewer Focusable="false" x:Name="DG_ScrollViewer">
<ScrollViewer.Template>
<ControlTemplate TargetType="{x:Type ScrollViewer}">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Button Command="{x:Static DataGrid.SelectAllCommand}" Width="{Binding RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}, Path=CellsPanelHorizontalOffset}" Focusable="false" Visibility="{Binding RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}, Path=HeadersVisibility, Converter={x:Static DataGrid.HeadersVisibilityConverter}, ConverterParameter={x:Static DataGridHeadersVisibility.All}}" />
<DataGridColumnHeadersPresenter Grid.Column="1" Name="PART_ColumnHeadersPresenter" Visibility="{Binding RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}, Path=HeadersVisibility, Converter={x:Static DataGrid.HeadersVisibilityConverter}, ConverterParameter={x:Static DataGridHeadersVisibility.Column}}"/>
<ScrollContentPresenter x:Name="PART_ScrollContentPresenter" Grid.Row="1" Grid.ColumnSpan="2" CanContentScroll="{TemplateBinding CanContentScroll}" />
<ScrollBar Grid.Row="0" Grid.RowSpan="2" Grid.Column="2" x:Name="PART_VerticalScrollBar"
Orientation="Vertical"
Maximum="{TemplateBinding ScrollableHeight}"
ViewportSize="{TemplateBinding ViewportHeight}"
Value="{Binding Path=VerticalOffset, RelativeSource={RelativeSource TemplatedParent}, Mode=OneWay}"
Visibility="{TemplateBinding ComputedVerticalScrollBarVisibility}">
</ScrollBar>
<Grid Grid.Row="2" Grid.Column="1">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="{Binding RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}, Path=NonFrozenColumnsViewportHorizontalOffset}"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<ScrollBar Grid.Column="1"
Name="PART_HorizontalScrollBar"
Orientation="Horizontal"
Maximum="{TemplateBinding ScrollableWidth}"
ViewportSize="{TemplateBinding ViewportWidth}"
Value="{Binding Path=HorizontalOffset, RelativeSource={RelativeSource TemplatedParent}, Mode=OneWay}"
Visibility="{TemplateBinding ComputedHorizontalScrollBarVisibility}"/>
</Grid>
</Grid>
</ControlTemplate>
</ScrollViewer.Template>
<ItemsPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" />
</ScrollViewer>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsGrouping" Value="True">
<Setter Property="ScrollViewer.CanContentScroll" Value="False"/>
</Trigger>
</Style.Triggers>
</Style>
But I need to set ItemsPresenter into some control(Border , Grid or Decorator etc.):
...
</ControlTemplate>
</ScrollViewer.Template>
<Border>
<ItemsPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" />
</Border>
</ScrollViewer>
...
In this case, virtualization doesn't work, in spite of "VirtualizingStackPanel.IsVirtualizing = True".
Do you know some way that solve this problem?
Thanks.

Just as I suspected,

You have to set the CanContentScroll to true if you want to use Virtualization.
You can also set the ItemsPanel of DataGrid to VirtualizingStackPanel.

I tried to set ItemsPresenter ScrollViewer.CanContentScroll = "True"... but there's no effect.
All properties used for virtualization are correct.
But if attach for application with Snoop, you can see all 2000 row controls.
DataGrid ItemsPanel is inheritor of VirtualizingStackPanel :
public class DataGridRowsPresenter : VirtualizingStackPanel
{
...
}
I think this is some limitation of wpf virtualization like grouping may be..

Yes that's also true. Good that you pointed it out.
Here is an article by Bea Stollnitz : http://bea.stollnitz.com/blog/?p=338[^].
Check its Limitations section where she has described that :
When using data binding’s “Grouping” feature, there is no support for UI virtualization.
That explains why virtualization is not working.
