Problem with checkbox binding in DetailsView

lvq684

Hi. I have a detailsview with a checkbox. This checkbox´s state should be determined from a ObjectDataSource which "fills" the detailsview. And, if the checkbox´s state is changed by the user, the ObjectDataSource´s UpdateMethod should of course save this new state. Problem is, that i dont know how to bind this checfield, since the 'Checked' attribute only takes true/false, and my data is in xml. Therefore i only have "true"/"false" data as strings. So how do i bind this checkbox state? And save the new state when the user changes it? Thanks alot!

what is the data type of your field you want to bind?

The data type is string. The field contains "false" or "true". And should be bound to the checkbox´ checked attribute which takes boolean. Thanks!

Try This

Checked='<%#(Eval("Field").ToString() == "true" ? true : false) %>'

Thanks alot! But it did not solve my problem. With this solution, i can DISPLAY the correct data (if the box are checked or not). But when the user updates the data (changes the checked state), the ObjectDataSource´s UpdateMethod sees the field as null. Is there a workaround on this? :)
