ActionScript 2.0 :: Get The Selected Index In A Datagrid?
Jan 18, 2007
How do you get the selected index in a datagrid, thats it
by the way the actual situation is that I'm tryin to show the data of a selected row in a datagrid, when a row is selected the current slide is set as invisible and the message_view slide is made visible and the data is shown in a text box. e.g.
I am performing a find operation in a datagrid on one of the columns. After I find the row containing the item, I make that as the selected index row, which highlights it. But now I also want to scroll the datagrid down or up (if the item is out of screen scope) to show that selected item automatically on this find operation.
I want the selectedIndex to remain the same. So, if I delete item 2, the next in the list should be selected. The problem is that if I delete item 2, item 3 will be selected and I have no idea why.
Is there any way to disable a few columns for a particular row in flex datagrid?
I have a datagrid with about 10 or more columns, say for example a few column names are: Item Id, Item Name, Item Status and VerifiedState. Initially I want the column Verified State to be disabled.
Now When the value of the column, Item Status is Review Passed for a particular row, I want the column VerifiedState to be enabled and editable. Is that possible in Flex datagrid.
In the following working example the list's selected index is supposed to reset to 0 whenever the text box changes. However, for some odd reason every other keystroke the selected item disappears and then reappears at the subsequent keystroke.
I have a combobox that displays a list of items from an array (we'll call this Array1). Of course, an item can be selected, and the user is displayed a small output describing the item that was selected.
I created another array that contains the URL for items in the above array, Array1. How can I get the index value of a selected item from Array1? Here is the code I used:

For example, if I selecte FontsForFlash, Flash outputs Fonts for Flash in the Output Window. How can I display the array position of Fonts for Flash instead of the name Fonts for Flash?
I have an application where I'm trying to update the String for a Label's text property, based on the tab which user has the mouse over. I've constructed a simple example displaying how I would process the eventHandler function if I was going to use the selectedIndex property, however it's the tab that has mouse focus, which may or may not be the selectedItem, that I'd like to reference and I haven't been able to figure out a way to do it.
So here is the example: <s:Label id="descriptionLabel" /> <s:TabBar id="audioTB" dataProvider="{audioVS}" mouseOver="audioTB_mouseOverHandler(event)" rollOut="audioTB_rollOutHandler(event)" /> [Code] .....
I have a mx Tab navigator and added several childs...I can use selectedindex(int) to open/select the respective (int) tab but How do I know the value of a selected/open tab?
I change an item in Spark List. The item then moves to a different index in the list since I keep the List's dataProvider sorted. However, the selectedIndex stays where the item used to be. I want the List's selectedIndex to still be on the item that changed.
How do i delete the selected row in datagrid, and how can i change the selection color. at present it turns blue, i want it be red on selection, and then on some button click want to delete the selected row.
selected rows (by mouse click) are not highlighted when i click once. but they highlights when i click twice. Maybe i'm not registering correctly the event ?
... and when i remove the event - evryting is work perfect.
here is the selectRow function
Code: private function selectRow(e:MouseEvent):void { if(e.target is CellRenderer) { // do something } }
Is it possible to dynamically show row index for DataGrid rows ?
I have a static ArrayCollection which is set to be DataGrid's data provider and I would like to always have row numbering for each populated row (e.g. in a column called "#").
I have a small flex datagrid. The dataProvider is an xmlList. I have two columns, userList and user permissions. The user permissions column as checkboxes. The values for the checkbox are stored as 0 and 1 in mySQL. While returning it from PHP, I am converting them to true or false. Its returning the values correctly to the frontend.
But inside the itemrenderer, the checkbox is not being set to true or false. Either everything is true or everything is false.

How can I correctly set the value of the checkboxes from the DB values?
I have a datagrid which is getting values from a XML file (getting this xml file from database using PHP and HTTP request in flex). i have created a checkbox in every row in data grid. and here is my requirement:i want to select tow or three check-box and would like to get all the values form that particular ROWs in some form , prefered arraycollection (such that i can pass this array directly to a bar chart) .. can some one help me as i am new to flex .[code]...
I have a cs3(AS3) datagrid component and I'm tracking which row the user has selected by using ListEvent.ITEM_CLICK to listen for a selection and then event.rowIndex in the handler function and using this index no to select data from the array which was used with the dataProvider. The problem is this. If the user re-sorts the rows using the column headers, this resets the rowIndex (ie the first entry is always row 0) and so this no longer relates back to my array. Is there a way to directly access some or all of the data in the row the user selects?
How should I go about matching the selected row of a sorted DataGrid to its source data row within its associated data provider?
For example, once a user sorts a DataGrid by clicking on one of the column headers, the target.selectedIndex from the CHANGE event (generated next time a row is selected) represents the index of the sorted row and not the index of the data as supplied by the data provider. Is there a simple way to map the index of the user selection back to the index of the original data?
Does not want to work for me. Tracing the expression in debug it is returning "XMLList (@11e55e8d1)".
The datasource is an XMLListCollection. tracing the expression myDataGid.selectedItem I can see the studentID node and it has a value.
I see that starting with Flex 4.5, Adobe recommends that we use the spark.components.DataGrid class as an alternative to the mx:dataGrid which I am not at all familiar with or where to start to learn. I have this mx:dataGrid all setup and otherwise working and would prefer not to have to learn something new.
I have a requirement to show an arrow mark when a row is selected in datagrid as shown in the attached picture.The selected line should show an arrow style instead of normal line.
i have datagrid and i want that when i click on my EmpName column popopmanager must be display and when i click on other columns it shouldnt display.and i want also edit mode in every column when i click opn it.
Using a standard Flex DataGrid, is there an easy way to determine the grid row index given the data object or index of the data object in the data provider? On the flip side, is there a way to get the index of an object in the data provider based on the DataGrid row index?
I have a datagrid that loads content from a database. Once the data has been loaded I have a function that has selectedIndex=0; Right after that I call another function that tries to display the selected item across a couple of labels. The problem is nothing loads in the labels unless I run the functions twice. I'm guessing its some sort of data race problem where the item hasn't been selected by the time the function that displays the items in labels runs. How can I get the item to be selected before the next function runs.
I am trying to use the same custom renderer for all the columns in a spark DataGrid. I need to know the dataField or columnIndex based on which I can change state in my custom itemrenderer.
Earlier in mx:DataGrid, this can be achieved by extending the MXDataGridItemRenderer which implements IDropInListItemRenderer and hence dataGridListData property is available.
But using the spark DataGrid, I am extending the GridItemRenderer which DOES NOT implement the IDropInListItemRenderer and hence unable to access dataGridListData property. I have tried to write an action script class extending GridItemRenderer and implementing dataGridListData but flex throws an error in the set function of this variable.
