in my grid i set a group field, and it's wotking fine.
is it possible when i have only 1 row, not to show it's group, and only when i have more then 1 row, it'l group them?

Hi Shachar,

You would have to derive a class from GridGroup. In your derived classes you need to override IsChildVisible.

Something like this:

public override bool IsChildVisible(Element el)
{
if( this != null && this.FilteredRecords != null
&& this.FilteredRecords.Count <= 1 )
return false;
else
return base.IsChildVisible(el);// Otherwise default behavior:
}


Please refer to the attached sample for more details.

this example is'nt what i'm looking for because it makes all the rows that have only 1 row in there group to disappear.
what i want is that all the rows with more then 1 row inside the group will be grouped and the others, that dont have any "brothes" will be displaed but not in a group.
is it possible?

Hi Shachar,

Please try this code snippet in IsChildVisible override method and let me know if you are looking something different.

public override bool IsChildVisible(Element el)
{
if( this != null && this.FilteredRecords != null
&& this.FilteredRecords.Count <= 1 )
{
if( el.Kind == DisplayElementKind.Caption )
{
this.IsExpanded = true;
return false;
}
else if( el is GridRecordsDetails)
return true;
else
return false;
}
else
{
return base.IsChildVisible(el);// Otherwise default behavior:
}
}

Here is a modiifed sample.
