DataGridCheckBoxColumn IsReadOnly="True" is ignored

[Eterance]

Describe the bug

When using ui:DataGrid, even if IsReadOnly="True" is set for DataGridCheckBoxColumn, the checkbox can still be changed.

To Reproduce

1. Use ui:DataGrid, add DataGrid.Columns, add DataGridCheckBoxColumn, and set a data source for DataGrid.
2. Set property IsReadOnly="True" to DataGridCheckBoxColumn.
3. Run the app.
4. You can see that the checkbox inside DataGridCheckBoxColumn can still be modified to change its checked state.

Expected behavior

While IsReadOnly="True", the checkbox inside DataGridCheckBoxColumn should be ReadOnly.

Additional context

It seems there is a potential solution available at: https://stackoverflow.com/a/37584805
Currently, I am using the following workaround to bypass this bug.
First, add the following style in the resources:

<Style x:Key="DataGridCheckBoxColumnStyle" BasedOn="{StaticResource DataGridCheckBoxElementDefaultStyle}" TargetType="{x:Type CheckBox}">
    <Setter Property="IsHitTestVisible" Value="False"/>
</Style>

Then apply the style to the DataGridCheckBoxColumn:

<DataGridCheckBoxColumn ElementStyle="{StaticResource DataGridCheckBoxColumnStyle}" />

The drawback is that the checkbox requires two clicks to be modified.

This is still an issue on version 4.0.1 and I'm unable to get the above workaround to work.

While waiting for a fix to be merged here, note that the base style had its name change to DefaultDataGridCheckBoxElementStyle.

It has been fixed, merged and released in version 4.2.1.
