Hidden Property (UltraGridRow)

Determines whether the object will be displayed. This property is not available at design-time.
Syntax
'Declaration
 
Public Overridable Property Hidden As Boolean
public virtual bool Hidden {get; set;}
Remarks

The Hidden property determines whether an object is visible. Hiding an object may have have effects that go beyond simply removing it from view. For example, hiding a band also hides all the rows in that band. Also, changing the Hidden property of an object affects all instances of that object. For example, a hidden column or row is hidden in all scrolling regions.

The bahavior of Hidden property with Row Filtering functionality has changed in UltaGrid Version 3.0. In previous version the Hidden property of a row returned false if the row was filtered out where as in Version 3.x the Hidden property will return the value it was set to regardless of whether the row is filtered out or not. Instead in Version 3.x IsFilteredOut property is added that indicates whether the row is filtered out or not. HiddenResolved behaves the same and takes into account whether the row is filtered out or not. Note though this only applies when the UltraGridOverride.RowFilterAction is set to HideFilteredOutRows.

Example
Following code illustrates how HiddenResolved property works. It takes into account various other factors besides what Hidden property is set to to determine whether a row is hidden or not. For example, if an ancestor of a row is collapsed or hidden, then the row would be hidden and HiddenResolved will return true regardless of the value of the row's Hidden property.
