Hello

I am setting a flag that is evaluated in ItemCheckedChanging. At times I need to stop an item from being checked. I have tried e.Cancel but it does not seem to work. In addition I looked for a property that contained previous checked state property but did not find anything.

I would like to be able to keep an item from being checked on a per item base.

Any suggestions?

Thank You

Hi Kem,

Thank you for writing.

I have tested the described scenario and on my end I can successfully prevent an item from being checked by setting the Cancel property of the arguments in the ItemCheckedChanging event to true. Additionally, from the event arguments you can access the Item and from there its CheckedState, where you can see its state before it gets changed. Alternatively in the ItemCheckedChanged you can get the changed value from the same property.

Please have a look at my project and see how it works. Let me know if I can be of further assistance.
