Flex :: Keep Selection After Refresh In Datagrid?
Jun 6, 2011My datagrid is filled with data from an Oracle database. The datagrid refreshes after 1 min. After that, I lose the selected item. I want to avoid that. Consider that it's quite possible that there is new data after refresh, so the selected index may no longer appear in the datagrid after a refresh.

View 1 RepliesActionscript 3 :: Flex - Selection In Flex Datagrid Does Not Pass The ValueObject To SelectionChangeHandler Function
Aug 11, 2011I have a TabNavigator, and each tab is a Module. One of the modules is labelled Units and the full code of the module is posted in this post. There are several problems:
1) Forms are not populated with data from the datagrid selection.
2) Selecting a row and clicking delete gives the very-common error: TypeError: Error #1009: Cannot access a property or method of a null object reference.
A trace on the valueObject unit within the selectionChangeHandler function gives NULL. Why? Note: In other modules (other tabs of the TabNavigator), I have DropDownLists populated with units. This means that the valueObject Unit is defined in the other modules. However, valueObjects should be private to modules, and not shared.

Flex :: Selecting Row On Selection Of CheckBox In Datagrid
Jan 5, 2010I have a datagrid with 5 columns. The first column has checkboxs and rest four columns have data from the dataProvider.
I have two relating issues: First: I want the row to get selected when I click on a checkbox, or if i click on multiple checkboxes, every row should stay selected in the datagrid for whose checkbox is selected.
Second: If a row or multiple rows are selected, the corresponding checkbox should get selected too.
My code is given below:

Flex :: Blue Selection Of Datagrid Row Programmatically?
Jan 28, 2010I have a question I came up with 3 days ago about how to do the blue underlining of a datagrid row programmatically. I thought to have found the solution, with just adding the column and row Indexes to the datagrids editedItemPosition Property.It turned out, that this is just practical if you want to be able to edit the grids row right away. But what if I just want to underline it with the blue color?Additionally how to detect that a list based Item got this kind of selection? es there a event to detect that? whats the name of this kind of selection?

View 2 RepliesActionScript :: Flex - Keep Selection When Refreshing Datagrid
Oct 20, 2010I'm working on my first ever AIR application with flashbuilder - just so you know. I've bound a mx:DataGrid component to a DataProvider which is a mx:HTTPService fetching an xml file with items. To keep the data up to data I'm polling the webservice on a given interval.
My problem is that I loose the currently selected item in my DataGrid when the data is updated. I've tried to save the DataGrid.selectedIndex and set when the data is updated, but I'm not sure when to do it?! The closest I've come is to restore the index when the updateComplete event of DataGrid is fired. This works, but the selection first fades away and then fades in - not updated soon enough. So what is the best way to keep the selection? (only one selected item at a time) And as a side question: is there a convenient way to only update the data when it has actually changed?
Flex :: Combobox Selection Inside Datagrid?
Mar 1, 2011I have a datagrid.In this datagrid I have a combobox item editor. This datagrid also has multiple columns where a user inputs numbers in each column. These numbers are then calculated by formula where the sum is posted in the "total" column. In this combobox there are two options for the user to choose from and each option has a different formula for calculating the inputted numbers. What I want is for when a user chooses "option 1" one formula is used to do the calculation, when "option 2" is chosen by the user then formula two is used to the calculation.Here's an example:
Combobox Option 1 (formula 1) is chosen by user = (Column2 - Column1) x column3 = "total" column
Combobox Option 2 (formula 2) is chosen by user = (Column1 - Column2) x column3 ="total" column
I realize you would use a conditional such as "if else" statement, but im just not sure how to do it. I've been trying to implement this for a while with no success.

Jun 29, 2011I have a custom skin applied to a Flex 4 spark datagrid. One really annoying issue I am having is finding the ability to override or change the selected row border color.

Anyone know where I can find this style or override this border that is being set when selection happens within the skin itself.

View 1 RepliesFlex :: Find Out Deselected Item In Spark List With Multiple Selection
Aug 3, 2010In a spark list I could use the change event to find out which item has been selected or deselected. The dispatched IndexChangeEvent object has the properties newIndex and oldIndex holding this information.
But with multiple selection allowed this doesn't work anymore because newIndex and oldIndex could refer to indices of still selected elements.
A solution would be to copy the selectedIndices vector to another variable and compare this variable with selectedIndices after a change in selection, but this seems to be somewhat complex.
Does anyone know if there is an easy way two get the index/item a user is deselecting while other elements are still selected?
Flex :: AdvancedDataGrid Multiple Cell Selection Highlight Not Fully Clearing
Sep 23, 2010I've two problems, the second of which is only an issue because it's a possible way to fix the first! I'm developing a Flex 4.1 application, using a Spark theme: I can't change these; Halo isn't an option. It's providing the facility to fill multiple-selected cells of an AdvancedDataGrid with a single character, from a single keypress. So the user selects their cells using the Shift key, hits H (for example) and sees all the cells update with H, without using an itemEditor but via grid keyDown events instead. Then they click somewhere else and the selection should clear.
However the visible selection isn't fully cleared and the newly coloured cells won't all change from their selected colour. Underneath I can verify that the selection has cleared: mygrid.selectedCells is empty. All behaviour afterwards points to some kind of display glitch with the grid: The cells aren't selected any more but they look like they are.

View 1 RepliesActionScript 3.0 :: ComboBox Selection To Update A DataGrid?
Nov 6, 2010I'am trying to create a Flex Application where users can select courses from a combo box based on the department that offers the course. The combo box has an XML variable as its data provider and has the different departments listed. When a user selects the department from the combo box the courses offered for that department should automatically update (show up) in the data grid under their respective columns. What it needs to do is retrieve the XML for the selected department and then set the data provider for the srcgrid accordingly. I am having a lot of trouble with things displaying correctly in the data grid. The course should be under Course ID, course name under Name, etc...
