We are pleased to introduce checkbox selection support in our 2019 Volume 3 release for both the WPF and UWP DataGrid. This feature will help you select or deselect rows by interacting with checkboxes in a column.
In this blog, we are going to see how to use a checkbox selector column in a data grid.
You can add a checkbox selector column to the DataGrid like any other column, and place this selector column anywhere in columns collection. You can use this selector column unbound, i.e. there is no need to have the property definition in the underlying ItemsSource.
<syncfusion:SfDataGrid x:Name="dataGrid"
AutoGenerateColumns="False"
SelectionMode="Multiple"
ItemsSource="{Binding Orders}">
<syncfusion:SfDataGrid.Columns>
<syncfusion:GridCheckBoxSelectorColumn MappingName="SelectorColumn"
Width="30"/>
</syncfusion:SfDataGrid.Columns>
</syncfusion:SfDataGrid>
Select all the rows by interacting with the checkbox in the column header.
You can get the checked items through the DataGrid.SelectedItems property as selection and checkboxes are synchronized together.
In the WPF platform, you can customize the style of the checkboxes in record cells through the CellStyle property and the checkbox in the header through the HeaderStyle property.
The following example shows how to customize the checkboxes in record cells.
<syncfusion:SfDataGrid x:Name="dataGrid"
AutoGenerateColumns="False"
ItemsSource="{Binding Orders}">
<syncfusion:SfDataGrid.Columns>
<syncfusion:GridCheckBoxSelectorColumn MappingName="SelectorColumn"
Width="30">
<syncfusion:GridCheckBoxSelectorColumn.CellStyle>
<Style TargetType="syncfusion:GridCell">
<Style.Resources>
<Style TargetType="CheckBox">
<Setter Property="BorderBrush" Value="Red"/>
</Style>
</Style.Resources>
</Style>
</syncfusion:GridCheckBoxSelectorColumn.CellStyle>
</syncfusion:GridCheckBoxSelectorColumn>
</syncfusion:SfDataGrid.Columns>
</syncfusion:SfDataGrid>
In the UWP platform, you can customize the checkbox feature by customizing its ControlTemplate.
