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.
flex 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 dataGrid in Flex to which data is added dynamically using dataGrid1.dataProvider=myArrayCollection;The DataGrid is non-editable and defined in mxml as [code]The data in myArrayCollection definitely does not contain duplicates.I am not able to select any row except the last.This occurs when I overlay the AIR 3 SDK on my copy of Flex
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.

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 want to display an image instead of Color in item Selection and Hovering(mouse over) in Flex DataGrid. how i can do it ?
View 2 RepliesI 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. My question is now how to select a item of a datagrid only programmatically, and how to get the mouseover effect and underlining the corresponding row with a bright blue color?
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?
the selection indicator isn't shown at the text input fieldis there any solution for this problem ?i am using flash builder 4.5 + flex in Android mobile Application

View 1 RepliesI am trying to display content of xmllistcollection in different fields in my datagrid however unless I use an itemrenderer the value is not displaying in the grid. The xmllistcollection is populated from a webservice call. Inside my item renderer i use a custom namesspace to retrieve contents from the xmllistcollection
value.ns::firstName
However if I try something like
dataField = "ns::firstName"
In the datagrid without using an item renderer I get no data output.

View 1 RepliesI have a number of thumbnail images (8K ish in length), stored in a sqlite database, encoded as base64 strings.
I would like to retrieve these images and present them into a datagrid (along with some other information from the DB)
The retrieval of information from the database works, but I cannot quite "see" how to connect the decoded result from the database to the datagrid, to display the images.
Below is some code, where I show (to simplify things) a simply DGrid and want to use the dataprovider to point to the select from the DB[code]...
I have an AdvanceDataGrid. How can I show the total of each column at the bottom. I am able to calculate the total, and tried displaying them on labels below each column by giving width as column width. But they are not getting aligned properly below each column.[code]Is there a way by which I can assign total to the grid itself instead of using seperate labels below.

View 1 RepliesI used HTTPService POST method to call a php file that returns me an xml type of result like
<user>
<name>jones</name>

This result is obtained after the php files queries a database. The database contain other information too like (height, gender, education and address)Now i have a DataGrid (having two columns: NAME and AGE) and a Form below the DataGrid. I have displayed the above mentioned xml data in the DataGrid using the dataprovider="{userRequest.lastResult.User}" attribute.
I now want to use the itemclick=itemClickEvent(event) so that when a user click on a row of the DataGrid other information related to the clicked row like (height, gender, education etc) may appear in the form which is placed below the DataGrid in the GUI. For now my itemClickEvent, look like:
private function itemClickEvent(event:ListEvent):void
{
clickRow.text=String(event.rowIndex);

I am trying to display a list of items in a datagrid from a XMLList.
<Series no="1">
<file>
<filenum>1</epnum>
<prodnum>4V01</prodnum>
[code]...
My current code allows me to retrieve every Series into an XMLList and then i have a nesteddatagrid class that allows me to do things like.
<classes:NestedDataGrid width="100%" height="100%" id="gridFiles" dataProvider="{filesList}" >
<classes:columns>
<mx:DataGridColumn headerText="Season" dataField="@no" width="60"/>
[code]...
However this displays the datagrid with two rows, the first row has 1 in the Series column and then the two files crammed into the second cell in the same row. The second row is the same but has the number 2 in the Series column and the two series #2 files crammed into the cell next to it.If i do not use the nested data class i can pull the files using Series.file instead and all 4 of the files list correctly, however i do not get the Series number for each...
On my flex (flash builder 4) DataGrid - DataGridColumn , I have set a custom itemRenderer
itemRenderer="myComponents.EncounterDGItemRenderer".
My renderer is a Label
public class EncounterDGItemRenderer extends Label
I found that my tooltips (datatips) stopped working once I started using this custom renderer. I also found that I can set the tooltip on the label in the
override protected function updateDisplayList
by setting:
toolTip=data['addedDate'];
This works find, however the problem is I need to choose a different data field based on the column. I was hoping for something similar to how a DataGridColumn labelFunction works - where I have access to "column.headerText" or "column.dataField". However I only have access to the underlying data object, not the name of what is being displayed (unless I am missing something).
Is there a way in a data grid item renderer to know what the column header text is, or do you have a different approach?
I have an AdvancedDataGrid that uses HierarchicalData to display data in a tree format. For one of the columns, I'm using an AdvancedDataGridRendererProvider to conditionally display an image if certain conditions are met. I'm currently using the ToolTipManager to display additional information if the user mouses over the image.Here's what I would like to do:Instead of showing the toolTip when the user places their mouse over the image, I would like to automatically display the toolTip whenever the image is visible in the AdvancedDataGrid. If the user scrolls through the AdvancedDataGrid, the toolTip should move and follow along with its image accordingly.
Sample AdvancedDataGrid:
<mx:AdvancedDataGrid id="myAdvancedDataGrid"
displayItemsExpanded="true"
