First of all, sorry for my late response. Alex, you are my hero! This solves the issue a "little bit". But to be honest, not completely.
Ok for documentation:
Now, in my MXAdvancedDataGridItemRenderer I use:
override public function set explicitWidth(value:Number):void
{
super.explicitWidth = value;
this.label.width = value;
}
With this function the height of the calculated ItemRenderer for printing is
correct. I think we have to update / change code the Default ItemRenderer which
are used for PrintDataGrid and PrintAdvancedDataGrid that the height is
calculated correct when someone is using only the Default ItemRenderer and
wordWrap="true" variableRowHeight="true" for the Print(Advanced)DataGrid. I
will test this, when my print works.
But there is still a print issue when I use colspan for some columns. I am
currently investigating this issue.
It seems that the every time the width and height of the columns (<mx:columns>)
will be calculated in the AdvancedDataGridBaseEx
measureHeightOfItemsUptoMaxHeight function, but rendererProviders for colspan
are not considered during this calculation. But I think during this calculation
we should look if there will be used maybe another ItemRenderer for colspan. So
if the Colspan-ItemRenderer is used, the Width and Height is of course not the
same as the height and width of the column-ItemRenderer. (I hope every body
understand what I mean. ;-) )
It's funny that I found this in the AdvancedDataGridBase.as Line 1600:
/**
* @private
* This grid just returns the column size,
* but could handle column spanning.
*/
mx_internal function getWidthOfItem(item:IListItemRenderer,
col:AdvancedDataGridColumn,
visibleColumnIndex:int):Number
{
return col.width;
}
Yea, I think this would definitively very helpful if this could handle column
spanning. ;-)
And a small issue when I print, the "pagebreak" of the PrintAdvacedDataGrid is
1 row "too early". When I look at my next page, the first row would perfectly
fit on the previous page. Ok, currently this doesn't bother me too much, but
this maybe can also be fixed.
Any help appreciated. Thanks
