Hi Everyone,
I was following this Demo and run into a problem. In the Web User Control(ascx) page, I need to Evaluate the CheckBox when editing a record. When I click on Edit, it work great but when I click on "Add new record", I'm getting this error:
Error: Sys.WebForms.PageRequestManagerServerErrorException: Specified cast is not valid.
This is coming from the Checked function. Below is my coding.
Can someone help me so ignore the Checked function when I try to insert a record or modify the above Checked code?

I feel so stupid for not thinking of this before but I figure out the answer. I just want to post it in case someone else run into this issue.
Checked='<%# DataBinder.Eval(DataItem, "ReadOnly") == DBNull.Value ? false : Convert.ToBoolean(DataBinder.Eval(DataItem, "ReadOnly")) %>'
