Hi Rajesh,
The Caption of the the "None" category groups can be hidden by creating a custom GroupinEngine and overriding the IsChildVisible method. Check for the group category in the override method when the element is a Caption, if it is empty then returning false will hide the Caption for the null category groups . Below is a code snippet
public override bool IsChildVisible(Element el)
{
if (el is CaptionSection)
{
if(el.ParentGroup.Category.ToString() != "None" )
return true;
else
return false;
}
else if (el is DetailsSection)
{
if (el.ParentGroup.Category.ToString() == "None")
return true;
else
return el.ParentGroup.IsExpanded;
}
else
return el.ParentGroup.IsExpanded;
}
Here is a sample.
