Not using Mode=TwoWay for DataGridTextColumns solves one version of the problem, however it seems that this problem can appear out of nowhere for other reasons as well. (Anyone who has a good explanation as of why not using Mode=TwoWay solves this in the first place is probably close to a solution to this problem) The … Read more
Please try that solution: <ListView> <ListView.View> <GridView> <GridViewColumn Header=”column1″ x:Name=”col1″/> <!–Column that shall resize: Width is set to the Actual Width of the helper field defined below–> <GridViewColumn Header=”column2″ Width=”{Binding ElementName=helperField, Path=ActualWidth}”/> </GridView> </ListView.View> Test Text </ListView> <!–This is the hidden helper Grid which does the resizing –> <Grid Visibility=”Hidden”> <Grid.ColumnDefinitions> <!–Width is bound to … Read more
I think Dave’s solution is a good one. However, one recommendation I’d make is to catch the PreviewMouseWheel event on the scrollviewer instead of on the datagrid. If you don’t, you might notice some minor differences based on whether you’re scrolling over the datagrid or the scroll bar itself. The reasoning is that the scrollviewer … Read more
figured out the XAML to get rid of selection style.. not ideal, but close enough.. <Style x:Key=”CellStyle” TargetType=”{x:Type DataGridCell}”> <Setter Property=”Foreground” Value=”Black” /> <Style.Triggers> <Trigger Property=”IsSelected” Value=”True”> <Setter Property=”Background” Value=”{x:Null}” /> <Setter Property=”BorderBrush” Value=”{x:Null}” /> </Trigger> </Style.Triggers> </Style>
Finally, this is what I ended up with for generically setting alternate row colors. <Style TargetType=”{x:Type DataGrid}”> <Setter Property=”Background” Value=”#FFF” /> <Setter Property=”AlternationCount” Value=”2″ /> </Style> <Style TargetType=”{x:Type DataGridRow}”> <Style.Triggers> <Trigger Property=”ItemsControl.AlternationIndex” Value=”0″> <Setter Property=”Background” Value=”#CCC”></Setter> </Trigger> <Trigger Property=”ItemsControl.AlternationIndex” Value=”1″> <Setter Property=”Background” Value=”#EEE”></Setter> </Trigger> </Style.Triggers> </Style>
You could set the BorderThickness for DataGridCell to 0 <DataGrid … SelectionUnit=”FullRow”> <DataGrid.CellStyle> <Style TargetType=”DataGridCell”> <Setter Property=”BorderThickness” Value=”0″/> <!– Update from comments. Remove the focus indication for the selected cell –> <Setter Property=”FocusVisualStyle” Value=”{x:Null}”/> </Style> </DataGrid.CellStyle> <!– … –> </DataGrid>
After ages of searching, I found a surprisingly simple way to do this that’s cleaner than the Got/LostFocus approach posted earlier: <DataGrid.Resources> <SolidColorBrush x:Key=”{x:Static SystemColors.InactiveSelectionHighlightBrushKey}” Color=”DarkGray”/> </DataGrid.Resources> This just sets the inactive background colour to DarkGray, leaving the active background colour to the default, but you can change that too using the SystemColors.HighlightBrushKey too of … Read more
The reason this doesn’t work is that the Label.Content property is of type Object, and Binding.StringFormat is only used when binding to a property of type String. What is happening is: The Binding is boxing your MaxLevelOfInvestment value and storing it the Label.Content property as a boxed decimal value. The Label control has a template … Read more
Pls, check if DataGridComboBoxColumn xaml below would work for you: <DataGridComboBoxColumn SelectedValueBinding=”{Binding CompanyID}” DisplayMemberPath=”Name” SelectedValuePath=”ID”> <DataGridComboBoxColumn.ElementStyle> <Style TargetType=”{x:Type ComboBox}”> <Setter Property=”ItemsSource” Value=”{Binding Path=DataContext.CompanyItems, RelativeSource={RelativeSource AncestorType={x:Type Window}}}” /> </Style> </DataGridComboBoxColumn.ElementStyle> <DataGridComboBoxColumn.EditingElementStyle> <Style TargetType=”{x:Type ComboBox}”> <Setter Property=”ItemsSource” Value=”{Binding Path=DataContext.CompanyItems, RelativeSource={RelativeSource AncestorType={x:Type Window}}}” /> </Style> </DataGridComboBoxColumn.EditingElementStyle> </DataGridComboBoxColumn> Here you can find another solution for the problem you’re facing: … Read more
Use a DataTrigger: <DataGrid ItemsSource=”{Binding YourItemsSource}”> <DataGrid.RowStyle> <Style TargetType=”DataGridRow”> <Style.Triggers> <DataTrigger Binding=”{Binding State}” Value=”State1″> <Setter Property=”Background” Value=”Red”></Setter> </DataTrigger> <DataTrigger Binding=”{Binding State}” Value=”State2″> <Setter Property=”Background” Value=”Green”></Setter> </DataTrigger> </Style.Triggers> </Style> </DataGrid.RowStyle> </DataGrid>
