Hi Sameer…

I have some sensitive data that I can’t publish openly on the blog. Though I am having trouble with Sorting a Column of an Advanced DataGrid that’s grouped by a different dataField key.

Would it be ok if you sent me an email and I’ll reply to you with the full source. (My email address is provided in this post).

Thanks

Also, all fixes and things I’ve been learning are being updated on my blog to help the community that also helps me.

Comment on GroupingCollection with improved performance by Sameer

HI Tom,
Copying ADG from Flex 4 to Flex 3.x wont work because some things are changed in Flex 4. You can search for and copy the usage of IGroupingCollection2 from Flex 4 ADG to Flex 3.x ADG.
Also, there are many bug fixes and performance improvements which have gone into Flex 3.x and Flex 4 both.

Interesting so can I try to copy ADG from Flex 4 into 3.x just the same? Since none of the grid components are true spark are they any more reliable? Seems like next to no work has been done to ADG in 3.x for over a year

As a new interface IGroupingCollection2 is introduced, there are some changes in the AdvancedDataGrid class to handle GroupingCollection2. That is why, GroupingCollection2 and Flex 4 AdvancedDataGrid works seamlessly.
But these changes are not present in the 3.4 AdvancedDataGrid and hence you have to do this workaround of setting the Grouping.label property to the same value as the column’s dataField.
You have to specify the same value for column’s dataField and Grouping.label property.

So this GroupLabel I’m aware of, but its interesting how with GC (1) I saw node labels and with GC2 I didn’t. I only had the expand/collapse arrows. And my group is pretty simple as I dont use Summary Rows.

All I used to have is:
groupField1.name = “someDataField”; // this is the label in my provider

Do I need to specify columnName in ADGColumn for this to work?

So, when the groups are made in GroupingCollection, the group node is stored as {GroupLabel:GROUP_NAME, …}
Now, by default the property is GroupLabel but you can change it by setting the Grouping.label property.
And yes this is present is GroupingCollection also.
The Class Grouping hasn’t changed.

Hi Tom,
You can set the Grouping.label property to the dataField of the grouped column. That way, you’ll not need a labelFunction.

Hi Sameer, I have found one bug in the sample..If innerGrid have more rows than outerGrid then some data will be clipped of innerGrid and it can not scrolls to its last row.

for testing:You can increase children of last row to 10 and make 8 rows in outerGrid.

Thanks
Sachin
