Subject: [flexcoders] datagrid
height
Hey guysI am trying something and
getting a strange behavior. I get an array of objects from the database
that becomes the data provider for my datagrid. I know the length of my
data provider thanks to the myDataGrid.dataProvider.length method and I figure
I could multiply that number by some arbitrary number of pixels to ensure that
however many items are in my data provider, thats how many rows are
visible in my datagrid on the screenso the datagrid is never scrollable.
Im using a method that sets thedataprovider
of the datagrid, myDataGrid.dataProvider = data; and then Im calling
myDataGrid.setSize(Stage.width 35, myDataGrid.dataProvider.length *
25);
The Stage.width 35 compensatesfor
some other things on the screen to look proportionate and the
myDataGrid.dataProvider.length * 25 is just guesstimating that each row in the
datagrid component is about 25 pixels high. Well the first time I tried
this, 25 was too large of a number so I adjusted it to 22, which seemed to work
but still left me with a little extra bit of a final row visible. Well
that was livable. Then I get a result set back that only had 2 items in
it, instead of the 5 I had been testing this whole thing with and now only one
row was visble and you have to scroll down to see the second row, so I
increased the 22 to 30 and that fixed it for that but now if I call the
original result set with the 5 items, I can see a row and a half extra blank
rows. Is there a better way to dynamically show the number of rows based
on the number of items in the data provider? I wish there was a size
attribute like there is with the HTML select list component where if its
a list you can say I want x-number of rows visible. I just dont
ever want the user to have to scroll within the datagridis there an
easier way to do this?
Thanks!
