Actionscript 3 :: Limit Flex Spark DataGrid ItemRenderer Data To Column

Feb 27, 2012

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.

Flex :: Flash - DataGrid Column Width: One Column To Rule Them All?

Nov 16, 2010

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.

ActionScript 3.0 :: Load Array Into DataGrid Column?

How can I do that easily? I was thinking of having a array with numbers [1, 2, 3, 4, 5]. But I suspect it is possible to do something like for...myDataGrid.row[i].rowNumber = i;

Flex :: Select A Column In Its Datagrid?

Sep 30, 2009

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?

Flex :: Datagrid Tab To Checkbox Column

Apr 15, 2012

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?

Flex :: How To Access Column For Particular Row In DataGrid

Apr 8, 2011

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.

Flex :: DataGrid Column Width Is Not Set Properly?

Jan 4, 2011

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.
