Best way to make a bound control readonly?

thegwill — Mon, 17 Sep 2007 08:58:04 GMT

I have a business object with a bound field that I display in a form. The field value is populated in code (as a default value for the BO) so the user should not be able to change it although they do need to see it

By defult, when editing, the control becomes enabled. I have remedied this by implementing the EditingStateChanged event on the BO instance on my form and explicitly setting the UI control.Enabled to false

Question is: this works but is there a better way to do this?

Larry is correct, you could do that. Another option is to make the property read-only. This will prevent the end-user from being able to modify that field as well. If this is a field that is pulled from the schema, you can assign this through the BO Mapper (it is a check box). If it is a custom property just assign it as read-only. The simplest option though may be Larry's suggestion if this is going to be a one time thing.

The easy way is to set the controls Enabled property = false and the IgnoreManagedReadOnlyState = true. This will prevent the control from being enabled when the bound object is being added or edited.
