Hide group summary row | Infragistics Forums

Hi NLPatrick,

From looking at your code I can't see anything that catches my eye. I assume you have some more stuff in code behind but without knowing that I can't replicate your grid exactly. I do however have an idea you can try that will let you hide the summary rows. Modify your SummaryRowCellStyle to include the following setter:

<Setter Property="Template">
<Setter.Value>
  <ControlTemplate TargetType="igPrim:SummaryRowCellControl">
   <Grid Loaded="Grid_Loaded">
    <VisualStateManager.VisualStateGroups>
     <VisualStateGroup x:Name="CommonStates">
      <VisualState x:Name="Normal" />
      <VisualState x:Name="MouseOver"/>
      <VisualState x:Name="Alternate" />
     </VisualStateGroup>
     <VisualStateGroup x:Name="SelectedStates">
      <VisualState x:Name="NotSelected"/>
      <VisualState x:Name="Selected"/>
     </VisualStateGroup>
     <VisualStateGroup x:Name="ActiveStates">
      <VisualState x:Name="InActive" />
      <VisualState x:Name="Active">
       <Storyboard >
        <ObjectAnimationUsingKeyFrames BeginTime="00:00:00" Duration="00:00:00" Storyboard.TargetName="ActiveRect" Storyboard.TargetProperty="Visibility">
         <DiscreteObjectKeyFrame KeyTime="00:00:00">
          <DiscreteObjectKeyFrame.Value>
           <Visibility>Visible</Visibility>
          </DiscreteObjectKeyFrame.Value>
         </DiscreteObjectKeyFrame>
        </ObjectAnimationUsingKeyFrames>
       </Storyboard>
      </VisualState>
     </VisualStateGroup>
     <VisualStateGroup x:Name="FixedStates">
      <VisualState x:Name="Fixed"/>
      <VisualState x:Name="Unfixed"/>
     </VisualStateGroup>
    </VisualStateManager.VisualStateGroups>
    <Border x:Name="AddNewRowElem" Background="{TemplateBinding Background}" BorderThickness="{TemplateBinding BorderThickness}" BorderBrush="{TemplateBinding BorderBrush}">
     <Rectangle Height="1" VerticalAlignment="Top" Fill="#7FFFFFFF"/>
    </Border>
    <Rectangle Fill="Transparent" Stroke="{StaticResource CellItemSelectedBorderBrush}" StrokeThickness="1" x:Name="ActiveRect" Visibility="Collapsed"></Rectangle>
    <StackPanel x:Name="SummaryDisplay" HorizontalAlignment="Right" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Margin="{TemplateBinding Padding}"/>
   </Grid>
  </ControlTemplate>
</Setter.Value>
</Setter>

This will basically re-template the SummaryRowCellControl and add a Loaded event handler to it so we have a place to execute some code. The code to execute would look something like below.

private void Grid_Loaded(object sender, RoutedEventArgs e)
{
Grid grid = sender as Grid;
SummaryRowCellControl summaryRowCellControl = VisualTreeHelper.GetParent(grid) as SummaryRowCellControl;
CellsPanel cellPanel = VisualTreeHelper.GetParent(summaryRowCellControl) as CellsPanel;
cellPanel.Height = 0;
}

This will hide the summary row. Let me know if you have any questions on this.
