Actionscript 3 :: Delete Multiple Rows (using Named Parameters) In Adobe AIR
Jan 31, 2011I am trying to delete multiple rows in the sqlite table in my Adobe AIR app (runtime 2.5).
Here is the statement, using the "IN" operator:
"DELETE FROM mylist WHERE tdId IN (tdId1, tdId2, tdId3, ...)";
Where tdId1, tdId2, etc. will be determined at runtime based on which row(s) the user chooses to delete. The user can delete arbitrary number of rows.
I've tried something like:
//delete statement text
"DELETE FROM mylist WHERE tdId IN :tdId";
//delete statement parameters: take 1.
[Code].....
It would seem too much of trouble to chain these deletes with a callback. So I guess I am using my last resort: building the sql at runtime. Conclusion: Cached statements can't be used in these kind of situations...
Flex :: Calculate The Sum Of A Datagrid's Rows?
Jun 6, 2010I have this datagrid which has columns with a NumericStepper as an itemEditor where the user can change the number of items he wants to buy. How can I calculate the sum of all cells when the user updates datagrid's values?
EDIT 1
My datagrid is about colors and sizes of a product. The columns are generated dynamically from this function
private function getColumn(dataField:String, headerText:String,editable:Boolean) : DataGridColumn
{
var column:DataGridColumn = new DataGridColumn(dataField);
[Code]....
the row.size28 is generated dynamically. So it could be row.size29,row.size30 etc.
How can I loop through all my cells without knowing their data.property?
Flex :: Order Of Rows In A Datagrid?
Jun 26, 2010I have a datagrid and it lists several rows as
seqno | NAME | COMPANY
1 | BOB | D&T
2 | Jenny | M&Y
3 | Jane | D&T
It is possible to have buttons as [MOVE UP] and [MOVE DOWN] so that when I select a row in a datagrid and press one of those button that the order changes and the seqno updates accordingly.
Meaning if I select Jane and press the [MOVE UP] button, the new order would be;
seqno | NAME | COMPANY
1 | BOB | D&T
2 | Jane | D&T
3 | Jenny | M&Y

View 8 RepliesFlex :: Swapping Columns And Rows Of DataGrid Possible?
Jul 22, 2009I have a 1 row, many column flex datagrid. I would like to turn the dataGrid on its side, so that the column headers become a single column running down and v.v. Is there a way to do that in the DataGrid? Or am I stuck manipulating the data presented to the grid?
I have an object like:
x=y
b=u
o=p
u=e
w=p
And I'd like a control that is visually similar to that. Currently the datagrid displays the object as:
x b o u w
y u p e p
Which is too horizontal for my case.

Flex :: DataGrid - Allow Headers For Different Groups Of Rows
Oct 27, 2009I am trying to extend the DataGrid to allow headers for different groups of rows. However, I cannot figure out which method to extend from DataGrid that would allow me to accomplish this. I do not want the headers to be included in the dataProvider, only the rows. I want to specify indexes to insert the headers at using a property of the custom datagrid.
Here is a quick photoshop showing what I am trying to do:

Php :: Displaying Rows - Extracted From A Database - One By One In A DataGrid
Oct 29, 2009I have a table (session) in a database which has almost 72,000 rows. I extract those rows with the help php+mysql but when the result is returned to the HTTPService, i need to wait for some 32 seconds before the all the rows start appearing in the DataGrid at once.
Question Is there any way by which DataGrid may start displaying data one by one while the application may extract next rows in parallel. Or that the DataGrid may show data in chunks of hundreds. Like when application starts, it may show first 400 enteries in DataGrid, then the next 400 hundred are extracted until all the 72,000 rows are extracted? Or can i involve threading such that one thread may be responsible for displaying data in datagrid while the other, executing in parallel may be responsible for extracting next data from database?

Flex :: DataGrid - How To Color Empy Rows
Jan 4, 2010My problem is that empy rows (if there are more rows that dataSource items then there are empy rows) look identical to rows binded to dataSource items which are empy (see the difference?). The only way to know the difference is to hover over them with the mouse, and if they are empty there's no color change, otherwise there's the blue background of the selection.. I want to change the color or in some way hide empty rows, those that are not bound to a dataSource item.

View 1 RepliesActionScript 3.0 :: DataGrid Locked Rows Background Color?
Sep 18, 2009I've got a reporting system that uses Flex Visualization charts for the GUI. The first row of a report is the header and the second is a summary row that sums all the data in that column for the data rows. The summary row is locked so that when you scroll down it stays at the top. In Flex 2.X I was able to change the background color of this locked summary row by overriding drawRowBackground and setting the color for the row with index 0. I upgraded to Flex 3.4 and now this no longer works. It appears to iterate over lockedRows separate from other rows, so drawRowBackground is called with a row index of 0 twice and the first data row ends up getting colored.
How are you supposed to change the background color of lockedRows in 3.4, or am I misusing this component and there is another way to achieve my goal here?
edit: mods I think maybe I misunderstood the name of this forum and this post actually belongs under ActionScript 3.
Flex :: Making Advanced DataGrid Height Of Rows?
Nov 17, 2009I have an ADG along with some other components in a VBox. The number of rows of items in the ADG is variable. I want the height of the ADG to be however tall it needs to be to show all the rows without scrolling. This is because I want the containing VBox to handle all the scrolling. The reason being, is because sometimes there is a horizontal scroll bar on the VBox, in this case you have to scroll all the way to the right to reveal the scroll bar for the ADG before you can scroll the ADG.

May 20, 2010I have a flex datagrid with 3 columns. The first column contains the image name(unique key). The other two columns have username and size details. I want to split the username into lastname, firstname, address and some other stuff. Can we have multiple rows in the grid for one image? Tried multi-line, it works but we need to keep adding spaces and its cumbersome. Since each row in the flex datagrid is represented by one index in the XMLList which is enumerated, is there a way to have more than one row assigned to one image and shown in the grid? something like this.
