XamCheckBox Editor in XamDataGrid toggling when clicking anywhere in cell

Hello.

I am using a XamCheckEditor as a field in a XamDataGrid. The current (what I assume to be default) behavior is that the checkbox is toggled no matter where in the cell I click. This is preventing me from being able to select multiple rows of checkboxes via Ctrl+Shift and using Ctrl+D to fill down. I am looking for a way to make the checkbox toggleable only when directly clicked on. Several suggestions online included setting the horizontal and vertical alignment and the FieldSettings.CellClickAction to “EnterEditModeIfAllowed”, but those were unsuccessful in my testing.

Thanks,

Casey

Hello Casey,

I have been investigating the behavior you are seeing in this case, but I am not seeing the behavior in which clicking anywhere in a cell toggles the XamCheckEditor within the XamDataGrid. On my end, it is necessary to click the actual checkbox portion of the editor to toggle the checked state.

I am attaching a sample project that demonstrates this behavior. Would it be possible for you to please modify this sample and send it back or provide some additional information about the configuration of your grid such that I can reproduce the behavior you are seeing?

Please let me know if you have any other questions or concerns on this matter.

Sincerely,

The issue happens because XamDataGrid enters edit mode on any cell click, which toggles the checkbox.

Stop auto toggle

<igDP:Field Name=”IsChecked”>
<igDP:Field.Settings>
<igDP:FieldSettings CellClickAction=”SelectCell”/>
</igDP:Field.Settings>
</igDP:Field>

Toggle only when checkbox is clicked

private void Grid_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
var dep = (DependencyObject)e.OriginalSource;

while (dep != null && !(dep is XamCheckEditor))
dep = VisualTreeHelper.GetParent(dep);

if (dep is XamCheckEditor editor)
{
editor.IsChecked = !(editor.IsChecked ?? false);
e.Handled = true;
}
}

Result

Click cell → no toggle
Click checkbox → toggle
Ctrl/Shift multi-select works
