binding to the opposite of a boolean

[Tops Software]

Hello,
This should be easy but I am struggling to find a solution. 

I have a radgrid with a custom edit form template I want to show one of the fields based on the opposite of a boolean field.
Something like this:

<tr id="trCloseDate" runat="server" visible='<%# Bind(!"j") %>'>

I dont think this would ultimately work though as I would need the user to be able to toggle at will. Something in the code behind would work better I think.

I have tried to do this in the code behind, using the onCheckChanged event but am running into issues as I cant find a way to get the tr control as it is not rendered yet, I believe, since it is later in the table.

Another weird side issue is that the checkbox is not showing the correct check if I use the changed event.

Thank you for your time.

Hello,

Please try with the below code snippet.

Visible='<%# Eval("j") == false ? true: false %>'

OR

Visible='<%# Convert.ToBoolean(Eval("j")) ? false: true %>'

Let me know if any concern.

Thanks,
