I have a spark datagrid with selectionMode="multipleRows".
I have three columns in the datagrid. I don't want the row selection to happen when the user's click falls on the third column of a row.
The row selection should happen only when one of the first two columns is clicked. How do I achieve this? There is a selectionChanging event for the datagrid, but the GridSelectionEvent object received in the handler does not seem to provide any information about the column on which the click happened.
I've got a DataGrid in my mobile application (I know, I know but there's currently not other solution for this), that numeric values. Depending on the value of a cell, the text gets colored. My big issue is that this doesn't work very for more than about 5 rows of data. I reckon the issue is that the set text function (in which I format the color) can't keep up with the amount of cell changes and formats the text based on the last updated cell of the row.I thought about a column item renderer so that the renderer only gets the value for that column, and not the whole data of the row.
Just for reference, this is my current item renderer (again, this works fine for few rows, for 5+ of fast changing data, this doesn't work any more, cells get formatted even though their data hasn't changed).[code]I just double-checked and have to revert my previous statement. A single row works fine, the second row already messes up the color formatting though. It seems as if the datagrid somehow throws together the values. Doing the color formatting in the set data method shows the exact same effect;[code]My assumption about the grid messing up the ItemRenderer's data seems to be correct.A simple trace in the set data method (trace("old: " + _oldVal + "new : " + value[column.dataField]);) revealed that somehow, values of the next grid row (in case there are 2) get used as well as _oldVal gets the old value of the next row.
I have a spark DataGrid component with several columns and I want to have my application default to descending order on the first column in the DataGrid. I would like to use the built-in default sort that occurs when clicking the top header once. I have no need to sort the ArrayCollection I'm working with or change what the comparators are.I also want any user-generated sorting such as clicking on a different column's header to override the default sorting.
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.

I have a Flex 4, mx:DataGrid with the following (pertinent) properties set:
width="100%"horizontalScrollPolicy="off"
I have the minWidth set on all of the DataGridColumns and the width set on one of them. If I simply maximize/minimize the display (in browser or stand-alone flash player) of the application, the columns scale up and down nicely. But if you grab the edge of the application and drag it to make it bigger, only one column grows really big. When you drag the size down again, the one column remains big, but all of the other columns get squished way down.
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);
In my flex app I store the widths and visiblility of columns in an xml file. When the app loads it reads from the xml file and sets he columns values as applicable:
In a flex datagrid, by default clicking on column headers does sorting. I want it such that if a user clicks a column header the entire column is selected. I have the datagrid listening for the HEADER_RELEASE event so I know when the column header is clicked.
How can I have the column and header appear highlighted similar to how a row is highlighted when selected?
Context: I have a data grid where the following has been implemented. tabbing through each column in a single row and creating a new row when tabbing from the last column. The last column in my datagrid is now a checkbox. I set the 'editable' to false as shown below (since we don't want editable text to be shown when user clicks on/tabs to checkbox.
Problem: When I tab through the columns of a given row, I cannot tab to the checkbox column and therefore cannot use the space bar to toggle between checked/unchecked. The user is forced to use the mouse to toggle the check box. Question: How do I let user tab to the checkbox column, and press spacebar to toggle between checked and unchecked?
We have a Datagrid:[code]where practiceJoinRequestThicks is an ArrayCollection of PracticeJoinRequestThick object.The PracticeJoinRequestThick has an Practice Object.Practice has an arraycollection "PracticeContactAddresses" which is an arraycollection of PracticeContactAddress object and Practice ContactAddress object has Address object which has the field city:String.Now when I try to display the City, it does not work.
I have defined the datagrid as followsmx:DataGrid id="dg" width="100%" height="100%" >n the part i am trying to get the details from the database and setting the dataProvider for the DataGrid as follows.
var arrayContent:ArrayCollection = new ArrayCollection(); for(var i:int=0;i<assetClassDetails.length;i++) {
I am stuck in a problem working on Flex datagrid, in an AIR application. How can I access a specific row in datagrid in Flex. I am not talking about the selectedItem or any particular record of dataProvider of datagrid. What exactly I want to do is I am showing some files data (name, description etc.) on a datagrid, and the data of these files comes from an array which is the dataProvider of the datagrid. Now when these files are being uploaded one by one to the server (using a webservice), I want to show a ProgressBar on, say, "Progress" column in the datagrid. How can I access this column for a particular row in datagrid i.e. current file being uploaded.
Tried col.setStyle('percentWidth',20) //doesn't work col.setStyle('percentWidth',0.2)//doesn't work && col.percentWidth //doesnt compile Where col is one of the columns in a datagrid.
I'm loading some images from a database using a PHP script through CodeIgniter, but when I try to add an event handler to do some stuff with these images, Flex compiler is showing me an error:1180: Call to a possibly undefined method cloneCar.Why I can not add an event handler in this context?
I wanted to ask if there is a possibility to have both strings and radiobuttons in one column depending on the value of another column perhaps|column1 | column 2 | |r | radiobutton||s | string |If there is an r in column 1 in column2 should appear a radiobutton, otherwise column 2 just shows a string.
I have an array like the following one public var sal:Array=[ {empNo:1001, sal:1000, exp:400}, {empNo:1002, sal:3000, exp:240}, {empNo:1003, sal:1000, exp:452}, {empNo:1004, sal:5000, exp:348}, ...... {empNo:1550, sal:2000, exp:330}, ];
I need to show data using a 3 row flex data grid where the first row will display empNo, the second row will display corresponding salary(field sal), and the third row will display Expenditure (field exp).
I have a column in a data grid that has the values of "Monday", "Tuesday" etc, as varchars, and I wanted to know, how do i sort the column to be in the correct order. Doing a normal sort doesnt work obviously, as the days are not alphabetically ordered naturally (Wed after Thurs). I am assuming some sort of itemrenderer, but anyone got a snippet of code to illustrate how this would work?
In flex, I have a datagrid with 22 columns. I initially display all the columns. The width of each column right is uniform. Now when i change the visiblity of a few columns, the width of each column varies. How do i maintain a uniform column width for each column whether or not there are any invisible columns? how do i get the count of number of visible columns. the ColumnCount property returns total number of columns and not the number of visible ones.
Is it possible to call the function by using the datagrid column item?I want to call the function while the user click the particular column item in the datagrid?
In the below example I has called the OptimizeDataGrid method on Button Click event to resize the Column according to the data. whereas on the First Time of the Button Click event It called the function whereas the Datagrdi Column width alone is not set properly.whereas on second time it is working properly.For Eg : In the below statement the text value is coming as 55 and widthPadding is comes as 25. but the sum of these two value is not in the dg.columns[col].width.
dg.columns[col].width = text + widthPadding;
But the same is working on the second time of the Button click event.
