Flex :: Get The Value Of A ComboBox That Is In A DataGrid?
Oct 6, 2009
I have a data grid that has ComboBoxes in two of its columns.
What I need to do is get the values of those bombo boxes when a user highlights the row of the grid NOT when the user uses the comboBox. I understand how to pull the values out once the change handler is invoked on the comboBox, but I'm not seeing a way to get at the comboBoxes that belong to the currently highlighted gridRow.
I'm sure it's really straight forward, but I'm just not able to find any reference on how it's done.
I have a DataGrid with a ComboBox as an ItemRenderer for one of my columns. When the user selects a row, I want to get the ComboBox's selected value for the selected row.
EDIT: I should have mentioned that the dataField2_Array property in myData is actually an Array is the dataProvider for the ComboBox. Each object in myData could have completely different values in that Array so the ComboBox in each row of the DataGrid could have completely different options to pick from.Some sample code:
How can I filter a datagrid based on the value in the combo box? Can anyone show me some good examples on it?
In my application, I already filter a datagrid based on the text entered by the user. I check if the entered string matches the column entry of the datagrid and if a match is found,the filterFunction on the dataprovider is called.
searchCriteria is the comboBox,where I have the items, "ALL","HIGH"...I have two rows with value "high" and I get the Alert "yes" for two times only.. But in the data grid all the four rows are displayed.
I use this arrayCollection to populate a Flex 3 Datagrid. I'd also like to use this arrayCollection to populate a comboBox with the Name node.
In the arrayCollection, I've got the Name listed twice. I've got two rows in the Datagrid.
If I set the ComboBox's labelfield to Name, then the Name will be listed twice in the ComboBox menu. Is there a way to use this arrayCollection and have each Name listed only once in the comboBox?
I can always make another loop and array collection for the Name, but I was wondering if there were a better way.
var i:uint; for (i=0; i<myArray.length; i++){ myDGArray = [
I know AS3Commons-collection framework is a good one, but it can't use in ComboBox, recently.I try to use LinkedSet data structure to retrieve and store data in ComboBox, any one can help me?
I'm trying to update a combobox/datagrid sorter that came from flex3 to a flex4 version but I keep getting an error that my newbie brain is not processing. The error is "1067: Implicit coercion of a value of type Array to an unrelated type mx.collections:IList."
I 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.
I want the comboBox to be placed in one of the columns of the datagrid header.The datagrid should be filtered according to the value selected in the comboBox.e.
I have a data grid with an Combobox itemRenderer in it. What I have is a grid with a person id and person name (more stuff in grid but I am struggling with this). In the person name column I have an combobox with all the people on then system's names and id's. What I want to do is when I select a person in the combobox I want the combobox to populate the person name fields (which it does) but I also want to pull out the person id from the combobox and populate the person id column in the data grid as well.
I have a very strange problem in a Flex 3.4 Datagrid. One of the columns is a ComboBox - I have my own custom renderer for the ComboBox. I use it to select my data and then make a "save" to the db. Upon return the comboBox loses its value. Even stranger is that when I scroll the datagrid area to the left (by moving scrollbar right) - the values in the ComboBox change!! When I scroll the datagrid right (by moving the scrollbar left) - the values in the ComboBox don't change.
recently, I research for the collection framework, and find LinkedSet(AS3Commons collection framework,it is a good opensource framework) written in ActionScript, but it can't use as dataProvider in ComboBox or DataGrid, because only implements ICollectionView can use as dataProvider. So I want to try if a class implements ICollectionView can work or not. I know Flex has build-in class implements ICollectionView, but I only want to define a class not use build-in class. The class as simple as possible.(can work is enough)
I am trying to put a combobox inside a datagrid. I managed to get it this far:
[URL]
Shown in that image is my combobox, populated with data. The problem is that if I set the selectedIndex of the combobox to whatever value is in the corresponding cell, the user can no longer change the value of the combobox. What I mean is, you click on the combobox, a list appears to select from, but you can not select any item in that list.
I've been stuck in the last step when trying to embed a ComboBox into a DataGrid through AS3.0( I am not yet a fan of Flex, so pls don't bother).Now you can click on the combobox embeded in the datagrid and have the dropdown list as normal, but the content of the cell always remain the same(the first itemlabel of the ComboBox)Here is the code:
1. Firstly in the Main Frames: import fl.controls.listClasses.CellRenderer; import fl.controls.DataGrid;
I need to put a combobox in a column of a datagrid. The user just need to select a value from the existing combox items.I know I need to use a custom cellrenderer. Please see my current attempt below.This attempt successfully inserts a combobox into the datagrid, BUT without any data in the combobox. In fact, when I click on the combobox in the datagrid, it is the same as a normal combobox on the stage without a dataProvider. In other words, it doesn't even open.Thus, I need to know how to modify my cellrenderer to correctly add the data to the combo and accept changes made by the user when selecting a value from the combobox.[code]
The following code is the cell renderer for for a ComboBox in a DataGridColumn. It works fine when setting the comboBox's data in the constructor. There's a problem using the red code below. If the DataGrid row is not already selected the dropdown list appears but is empty.Any ideas? If the row is not already selected, the selectedItem is being set causing a STATE invalidation after the list a created. I'm not sure how to prevent this.
I'm trying to set a specific list item in a mx combobox to have a custom item renderer, the problem is that I cannot do this via mxml, it needs to be done via actionscript at a later stage, eg: combobox gets created, combobox gets populated, user does other tasks, combobox needs to set one or more items in the combobox to have icons (via item renderer)..
I can do this via the onChange event, but it only applies the icon when the combobox is opened and there is a slight delay so you can see the icon being added.
I am trying to populate a datagrid based on a value selected from a combobox. The data comes from a xml file, which looks something like this,[code]The user can list data in the datagrid based on either "media" and "region." For example, the user should be able to choose "Europe" from the combobox and list "only" media having "Europe" in the region tags. In this case, if the user chooses "Europe" from the Combobox only one listing (rammstein) will be seen in the Datagrid.However, it doesn't work. I get a blank datagrid. Loading data into the datagrid is not the problem, because if I just use a straight For loop with no conditions I fill the datagrid no problem. The problem comes up when I try to control what data get listed in the datagrid based on selected value in the combobox.[code]
I'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...

I m using FLASH CS3, I used Datagrid and Combobox component from components panel, and simply add some data inside in that. setupComboBox(); function setupComboBox():void { cb.setSize(200, 22); cb.prompt = "Select a Credit Card"; cb.addItem( { label: "MasterCard", data:1 } ); [Code] ..... It seems working fine. My problem is, I want two different type of skining of two different component (DataGrid & Combobox). in the same fla. E.g if datagrid have gray color skin type and combobox have black color skin type.
URL...In this demo I have a Datagrid populated from a php script.I also have a ComboBox embeded in the datagrid. In this example I am reading the ComboBox data from an array within a ComboBox CellRenderer.The question I am posing is how to dynamically populate the embedded ComboBox's from a php script with data retrieved from a mySQL table.
I've added an eventListener to the COLLECTION_CHANGE event that is fired when the grid is finished resorting the items in its dataProvider, after the user clicks on a column header:MyType (myDataGrid.dataProvider).addEventListener(CollectionEvent.COLLECTION_CHANGE,onDataGridResort);
I am working on a problem since a week soon, but I still couldn't make it work as expected. I have a DataGrid which has HBox with a CheckBox an a Label as itemRenderer (see Code below). When I tap in to the Cell the standard itemEditor pops up and lets you enter the content of the label. Thats the standard behavior. I works fine except for 2 problems:
If I enter to much text, the horizontal srollbar pops up, and the cell is filled with that scrollbar. As you see I tried to set the horizontalScrollPolicy to off, but that doesnt work at all... I tried to do that for all the different elements, but the failure is still existent. When I have filled more than one row, there is an other mistake happening. If I tap on a row, the datagrid selects the one below that row. That's only if one line is already selected. If I tap outside the datagrid and then, tap at any row the itemEditor of the right row will show up... Is there anything now wright in the setup of my set data method?
Both have single columns. Selecting one item from Divsions datagrid should display members of that Division in the Members datagrid. But following code has some problem and Members of a particular division do not show up when respective Divsion is clicked.
Following are some snippets of the related code. Hope someone can spot an error in it.
For poor performance reasons, the DataGrid will cache checkboxes and reuse them for different rows. If you have 50 rows, it won't create 50 checkboxes. It will create as many checkboxes at are visible, plus a few more for padding, and then reuse them as you scroll. This is why you need to explicitly manage their state. How can improve it ? How can fixed checkbox value ? i used checkbox like below But checkbox doesnot remembering the values
I am attempting to style the headers in a flex datagrid and I keep getting the warning:
Type DataGrid in CSS selector 'DataGrid' must be qualified with a namespace
What does this mean? I have gone through a bunch of tutorials and none of them have worked. It seems like changing a the colors in a datagrid should be relatively simple.
