Xml :: DataGrid ItemRenderer Error - Button Appear Only On Certain Rows Of The Column

Aug 25, 2011

I am populating 3 columns of my datagrid using a simple XML file. The last column is supposed to be an itemrenderer, basically a Button. However the button should appear only on certain rows of the 3rd column of the datagrid depending on the value from the XML file, which is either "true" or "false". So basically I want to set the Visible property of the button in the itemrenderer to true or false.

Flex :: Creating Multiple ItemRenderer For DataGrid Column

Aug 25, 2009

I actually wanted to create an itemrenderer which will contain below code :
<mx:HBox xmlns:mx="[URL]" width="0" height="0" >
<mx:Label text="{data.xval}" />
<mx:Spacer width="100%" />
<mx:Image source="edit.gif" width="16" toolTip="Edit" />
</mx:HBox>

Now when I click on the image datgrid column should be editable, for that I am using a textinput as an itemeditor. Now I also want to highlight all those cell for this datagrid column which are having data more than 8 characters. I am able to do this separately using 2 different itemrenderers. But I want to get this all together. Can we have multiple itemrenderer for any datagrid column?

Flex :: ItemRenderer Doesn't Resize With DataGrid Column

Mar 7, 2012

I have an item renderer tied to an mx:DataGrid column. The renderer used to be inline with the column, but I've moved it out to its own file so I can reuse it across multiple tables.

The problem is that now the renderer doesn't resize (grow/shrink) when the column is resized. So if the user makes the column very small, the contents displayed by the renderer just eat up space and show up over top other columns

Code for Item Renderer:

<?xml version="1.0" encoding="utf-8"?>
<s:MXDataGridItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"

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 :: ItemRenderer Shows Through ItemEditor On AdvancedDataGrid

Apr 5, 2011

When not editing the cell, it shows a centered date as plain text. When editing, it shows a DateField editor. The second example is exactly the same as far as I can tell, other than the fact that it is an AdvancedDataGridColumn. Using that code with an AdvancedDataGrid, when I go into edit mode I can see the text from the normal item renderer behind the DateField editor (between the text input and calendar icon).

Example 1:

<mx:DataGridColumn id="endColumn"
dataField="endDate"
headerText="End"

Actionscript 3 :: Get Column Index In Custom Itemrenderer For Spark Datagrid

Jan 16, 2012

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.

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.

Flex :: DataGrid With Variable Custom ItemEditor On A DataGridColumn?

Flex :: DataGrid Lines Showing Through ItemEditor - Opaque?

Sep 18, 2010

I have a datagrid column as follows:
<mx:DataGridColumn
headerText="Description"
dataField="description"
editable="true"
editorXOffset="2" editorYOffset="2"
editorHeightOffset="20" editorWidthOffset="60"
itemEditor="com.jono.controls.DgItemEditor"
wordWrap="true"
/>

And a very simple DgItemEditor:
<?xml version="1.0" encoding="utf-8"?>
<mx:TextArea xmlns:mx="[URL]" wordWrap="true" backgroundColor="#FFFFFF" backgroundAlpha="1">
</mx:TextArea>

Basically, this allows for a small 'popup' when the user edits a cell in the datagrid, allowing for more space to type. The problem that I am having is that the datagrid gridlines show through the itemeditor - i.e. the itemeditor is transparent. Is there any way that I can force it to be opaque?

Flex :: Scrollbars In Dropdownlist Inside DataGrid ItemEditor Not Working

Aug 17, 2010

I have a DropDownList inside the itemEditor of my DataGrid. There are enough items in the DropDownList to justify scrollbars. You can see the scrollbars, and the mousewheel works fine. If you move the mouse over the scrollbars, they'll change appearance fine (mouseover is working). If you click on them, the DropDownList closes as if you'd clicked elsewhere in the data grid.

I've been experimenting with custom skins hoping to find a way to trap the mouse event, but have been unsuccessful.

FWIW, this is Flex4, as an AIR app.

Flex :: Improve Datagrid Performance When Using Itemrenderer With In Datagrid?

Jul 31, 2009

For 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

Flex :: Datagrid With RadioButtonGroup Itemrenderer

Aug 12, 2009

I have an AC with several questions and assoicated answers. These must be shown in a DG, and the idea is that the rows and colums of the DG are bound to the AC. For example, if the answer to question1 is Yes, the Yes-button must be true, and both the others must be false (as in normal radiobuttongroup behaviour). But when I change a button by clicking it, the actions datafield of the AC should change accordingly. Am I clear enough here?

It is ment for dynamic questionnaires.

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?
