How to avoid an InvalidOperationException when clicking AddNewRow while AllowEditing property is disabled for GridCheckBoxColumn in WPF DataGrid?

In WPF DataGrid (SfDataGrid), an InvalidOperationException will occur when attempting to add a new row for GridCheckBoxColumn while the AllowEditing property is false. This issue arises because the property bound to the GridCheckBoxColumn is read-only and provides only a getter.

The AddNewRow process is typically handled within the checkbox click event. This event depends on the IsHitTestVisible property. When IsHitTestVisible is set to false, the event is not triggered. This behavior is consistent with the framework's default handling of checkbox, which is influenced by the IsReadOnly property.

To prevent the exception, the IsReadOnly property should be set to true for the GridCheckBoxColumn. This configuration avoids triggering an InvalidOperationException during the process of inserting a new row with read only property.

<syncfusion:SfDataGrid x:Name="dataGrid"   
                       ItemsSource="{Binding Orders}" 
                       AutoGenerateColumns="False"
                       AddNewRowPosition="FixedTop"
                       AllowEditing="False">
    <syncfusion:SfDataGrid.Columns>
        <syncfusion:GridNumericColumn MappingName="OrderID" 
                                      HeaderText="Order ID"/>
        <syncfusion:GridTextColumn MappingName="CustomerName" 
                                   HeaderText="Customer Name"/>
        <syncfusion:GridTextColumn MappingName="Country" 
                                   HeaderText="Country"/>
        <syncfusion:GridCheckBoxColumn MappingName="Status"
                                       HeaderText="Status"
                                       IsReadOnly="True"/>
    </syncfusion:SfDataGrid.Columns>
</syncfusion:SfDataGrid>
