I am using the following code to create single click checkbox in a wpf DataGrid.
<DataGridTemplateColumn Header="Select">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<CheckBox Margin="16,3,0,0" IsChecked="{Binding IsSelected, UpdateSourceTrigger=PropertyChanged}" />
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
This is the example output:
The checkbox is selected only if user clicks to the right of the checkbox. If the user clicks to the left of the checkbox, it is not selected. How to fix this? I want the checkbox to be selected if the user clicks anywhere on the cell where the checkbox is located.
CodePudding user response：
Create a custom template for the CheckBox or you could put it into a ToggleButton:
<DataGridTemplateColumn Header="Select">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<ToggleButton Margin="0" IsChecked="{Binding IsSelected, UpdateSourceTrigger=PropertyChanged}">
<ToggleButton.Template>
<ControlTemplate TargetType="ToggleButton">
<Grid Background="Transparent">
<ContentPresenter />
</Grid>
</ControlTemplate>
</ToggleButton.Template>
<CheckBox Margin="16,3,0,0" IsChecked="{Binding IsChecked,
RelativeSource={RelativeSource AncestorType=ToggleButton}}" />
</ToggleButton>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
CodePudding user response：
You could "just" make the checkbox bigger.
<DataGridTemplateColumn Header="Select">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Viewbox>
<CheckBox IsChecked="{Binding IsSelected, Mode=TwoWay}" />
</Viewbox>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
Or use something isn't a checkbox at all if selection of row drives it.
Eg
<DataGridTemplateColumn Header="Select">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Rectangle>
<Rectangle.Fill>
<VisualBrush>
<VisualBrush.Visual>
<Grid>
<Path Fill="Green" Data="{StaticResource Tick}">
<Path.Style>
<Style TargetType="Path">
<Style.Triggers>
<DataTrigger Binding="{Binding IsSelected, RelativeSource={RelativeSource AncestorType=DataGridRow}}" Value="False">
<Setter Property="Visibility" Value="Collapsed"/>
</DataTrigger>
</Style.Triggers>
</Style>
</Path.Style>
</Path>
<Path Fill="Red" Data="{StaticResource Cross}">
<Path.Style>
<Style TargetType="Path">
<Style.Triggers>
<DataTrigger Binding="{Binding IsSelected, RelativeSource={RelativeSource AncestorType=DataGridRow}}" Value="True">
<Setter Property="Visibility" Value="Collapsed"/>
</DataTrigger>
</Style.Triggers>
</Style>
</Path.Style>
</Path>
</Grid>
</VisualBrush.Visual>
</VisualBrush>
</Rectangle.Fill>
</Rectangle>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
Tick and cross are a bit big but:
