I want to add a column to my ggc that is a checkbox. I create the column and issued its UIElement to be of type "Checkbox" and I can see the graphic. However, when I mouseover the checkbox, my application terminates, and I get the following exception:

System.ArgumentException: Parameter is not valid.

Hi Patrick,

Thank you for your details.

I am afraid that I was not able to reproduce the exception. I have created a sample to test the issue and it is available in the

following link.

Please have a look at the above sample and if still the issue exists, could you please try reproducing it in the above sample or

send us the reproducing steps so that we could sort out the cause of the issue and provide you a solution?

Thank you for using Syncfusion Products.

Best Regards,
