A common question in our office especially the newbie users.
Problem: You want to use the Properties palette to change a view property, but the property displays in gray, and you cannot change it.
Issue: The property may be controlled by a view template.
Solution: Do one of the following:
- Modify the assigned view template: On the Properties palette, click the value for View Template. In the Apply View Template dialog, under View Properties, change the value of the target view property, or clear Include so the view template no longer controls that property.
Important: The change to the view template affects all other views that are dependent on the template.
- Disassociate the view from the template: On the Properties palette, for View Template, select None.
The view is no longer linked to the template. The view retains its current properties, but future changes to the template will not affect the view.
- Assign a new template to the view: On the Properties palette, click the value for View Template. On the Apply View Template dialog, select another template that defines the target property as desired, or that does not define the property at all so you can define the property for each individual view.
