Bind Tristate Checkbox

Question

Hello,I have a model with a nullable bool property. I would like to bind this property to a tri-state CheckBoxAdv, so I set the TriState property to true.Next step I bind my property to BoolValue property of the CheckBoxAdv.The problem is that the BoolValue property is false when my model property is null (I think it should be null in indeterminate state). This is a bug? If not, how can I bind my nullable property to the tristate CheckBoxAdv?Thank you!BR, SZL

Hi SZL,Since BoolValue is not a nullable bool, it will not accept the null value. You can use IntValue to bind with the integer value where 1 represents checked, 0 represents unchecked and -1 represents intermediate.

We will check and update you in two business days regarding binding the bool value to the CheckBoxAdv.Regards,Gokul T
