View 2 Repliesflex example to select multiple row selection in datagrid
View 1 RepliesMy 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 RepliesI 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.

Back again with another Flex question. I have an XML structure like...

Now I got his displaying on my grid by saying dataProvider=XMLListCollection... What I want to do is on selection of a row, check if it has "Address" tag, if it has display the other grid, else hide the grid.
I 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:
<mx:DataGrid id="dg_trashContent" allowMultipleSelection="true"
verticalGridLines="true"
dataProvider="{trashDataProvider}"

I 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 1 RepliesI have a DataGrid and I set the DataProvider to my data. When my data changes the DataGrid loses the selected row and the scroll bar jumps back to the top. How do I maintain the selection and scroll position?
View 2 RepliesI'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?
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 have an array list of data which i am showing in spark data grid. once i select an idem and click on a button that i have linked with datagrid it adds a panel on screen. I want to disable this selection i-e to tell that this item panel have already been added. Any ideas how can i do that?
View 2 RepliesI 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. I was able to set the selectionColor just fine but the border is still the default light blue color. I need it to be yellow.
Anyone know where I can find this style or override this border that is being set when selection happens within the skin itself.
I have a DataGrid, and what I would like to do, is when a user clicks on a row to select it, check a certain condition, and if it's met prevent the row from getting selected and keep the old selection intact.
View 1 RepliesI have two datagrids which should do everything synchronic except the data entry. I already managed to make them scroll synchronic by using the scroll event.

View 1 RepliesI have a spark datagrid on a mobile application, I set the
interactionMode="touch"
and the dataGrid scrolling is good, I got some problems adding a selectionChange eventListener to it, because scrolling the dataGrid will automatically change the selection and instead simply scrolling it, the function binded will start...
How can I add the touch dalay before select the index, so if I scroll the grid the selection won't change, and it change only if I press the item without scrolling?
What event is called when you click on an editable field to edit it, and then click off of the field? in a datagrid using Flex 4? If I'm not making much sense I'm trying to make a datagrid where you can edit the fields and once you're done editing those fields the application calls an event listener which triggers a save method.

View 1 RepliesI'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 want to create a custom list in Flex for an interface prototype. The list is supposed to have an image and 3 text fields. This is what I have done so far, the control displayed is what I want. But, when I click on one of the items, the item does not appear (visually) to be selected. I was not sure how I would implement this.
Here is my code so far:

View 2 RepliesI 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?

I never realized that fl.getDocumentDOM().selection doesn't retain the selection order... <sniff>. I was hoping to build relationships based on the order. I guess I took if for granted that tools like Maya and Max store the selection buffer in order of what was selected.

View 2 RepliesFor 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

View 6 RepliesI want to disable (and look disabled) some rows in a spark datagrid. I found this answer to stop selection which is greatIn flex, is there a way to capture and optionally cancel a row selection event in a DataGrid?
But I want in addition to show that the particular row is not selectable. Ideally I want to have some sort of overlay but I am not sure if that is possible. My alternative solution is to change the text color to grey for the unselectable row. Looking at the datagrid renders they all seem to be column based. I looked at skinning potentially (overriding the alternating color property) but this just sets the background property and not the text color.
