Flex :: DataGrid List Is Highlighting
Jan 10, 2011
By default, whenever you rollOver/mouseOver (not sure of the difference) an item in a Datagrid or a List, that item is highlighted with the component's rollOverColor.I'm just wondering if there's any way to do that programmatically. I haven't been able to find much help on the issue. For example,suppose I have two DataGrids.When I rollOver an item in the first DataGrid, I want to highlight the corresponding index in the second one as well.Basically, as if two separate cursors were rollOver'ing two separate DataGrids.

I want to create a custom list in Flex for an interface prototype. The list is supposed to have an image and 3 text fields. This is what I have done so far, the control displayed is what I want. But, when I click on one of the items, the item does not appear (visually) to be selected. I was not sure how I would implement this.
Here is my code so far:
<s:List width="400" height="220"
dataProvider="{arrColl}"
alternatingItemColors="[#EEEEEE, white]">
<s:itemRenderer>

We are rewriting our multiscreen game from Flex Project to ActionScript Mobile Project (root object is flash.display.Sprite and not spark.components.Application). Aim is to increase performance on tablets and have better overview what exactly is going on, what listeners are added and so. (I just don't trust Flex in this.). Do you know any alternative for DropDownList and/or DataGrid? I can't use MinimalComps, because there are little options to customize.

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...

I want to get rid of the typical Flex roll-over color in list-based components, and to display my own style of roll-over rendering. Setting useRollOver to 'false' is not an option, since disabling that will also make the List.isItemHighlighted() function to always return false. My custom renderer relies on that function. Can it be so hard? Is there no way of setting that roll-over color to transparent? Is there some other way for my renderer to figure out if an item is highlighted?

I'm using drag and drop on a DataGrid to reorder items. However, when the user holds down Ctrl he can initiate a drag Copy operation. How can I disable copying altogether? (not just cancel the drop, but also prevent Ctrl + drag from showing the (+) icon)

I'm trying to implement solr hit highlighting using a flex client. There are lots of examples out there to do high lighting in client side writing logic to do this, but couldn't find proper solution to tag them from back end (eg. some words<pretexttag>keyword<posttexttag>some words) so that it automatically highlight with results.

I am working on a problem since a week soon, but I still couldn't make it work as expected. I have a DataGrid which has HBox with a CheckBox an a Label as itemRenderer (see Code below). When I tap in to the Cell the standard itemEditor pops up and lets you enter the content of the label. Thats the standard behavior. I works fine except for 2 problems:
If I enter to much text, the horizontal srollbar pops up, and the cell is filled with that scrollbar. As you see I tried to set the horizontalScrollPolicy to off, but that doesnt work at all... I tried to do that for all the different elements, but the failure is still existent. When I have filled more than one row, there is an other mistake happening. If I tap on a row, the datagrid selects the one below that row. That's only if one line is already selected. If I tap outside the datagrid and then, tap at any row the itemEditor of the right row will show up... Is there anything now wright in the setup of my set data method?
package components
{
import mx.containers.HBox;
import mx.controls.CheckBox;

I have two datagrids:
- Division
- Members
Both have single columns. Selecting one item from Divsions datagrid should display members of that Division in the Members datagrid. But following code has some problem and Members of a particular division do not show up when respective Divsion is clicked.
Following are some snippets of the related code. Hope someone can spot an error in it.

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

Here is a snip from within my code:
[Code]...
The 'recommendations' dataProvider is an ArrayCollection of String, which are generally sentences about as long as this one. By setting the variableRowHeight and wordWrap properties as shown, if a sentence is too long to fit on a single line, everything works fine- the row expands and the messages show on two lines, or occasionally three.
The space allocated for this panel within the entire canvas means if the total text size of 'recommendations' exceeds six lines, I need for the entire list scroll. This is also working just fine. The trouble is when using the mouse wheel to do the scrolling- Flex scrolls both the entire list and the single item where the mouse is hovering. Often this results in only the second half of a sentence being visible. Non-programmer friends I have asked to look at this noticed this, and tell me it as a problem. If a user does not notice the dual scrolling, and sees only a fragment of a sentence, it will be perceived as an error in the application.

I'm trying to animate a list as I delete the top row. All the examples I can find use itemsChangeEffect to bind to the effect, but this property exists only in MX lists, not spark lists.
Any idea how I can get the same effect done in Spark Lists?
I'm trying to remove the top most item in the list with a slight fade out effect before the rest of the items move up to replace the gap.

The traditional way to assign an icon would be to use the icon field of the item renderer,which reads the value of "icon" property in your data, for example:
listData.addItem({label: "Logout", icon: "com.classpth.DefualtThemeLogoutIconClass"});
But i want the DefualtThemeLogoutIconClass to changed to another class: ightThemeLogoutIconClass when the theme is changed.The only way to do this would be to use a style declaration containing a classReference to the icon, and change its the value in each of the CSS files of the various themes.The question is, is there any way to assign this style to an icon in a List, something as easy as intuitive as list[0].getIcon().setStyle("styleName");

I am attempting to style the headers in a flex datagrid and I keep getting the warning:
Type DataGrid in CSS selector 'DataGrid' must be qualified with a namespace
What does this mean? I have gone through a bunch of tutorials and none of them have worked. It seems like changing a the colors in a datagrid should be relatively simple.
Here is a code sample:
<mx:Style>
.headerCustomStyle

fontWeight: "bold";

in Flex I have something like that: [code]and dg is ALWAYS pointing at DataGrid (even if dg1 has name DataGrid_test and dg2 = DataGrid_test2) and finally action is made on my first DataGrid (DataGrid_test).[code]and search still points at ColorColumn :/ My problem is really easy- I just want to pass to search different dataGrid on each state.But still I don't understand why it doesn't work. My search function uses algorhitm Boyer-Moor for searching through dataGrid.dataProvider for some text. If it find something then it is pushed into new array and after passing whole dataProvider I colorize rows with searched word.

I want to use it for what seems like a fairly simple application, but I am having a terrible time finding any tutorials that address this specific need. I've been through basic "how to us Flash CS5" training but I'm having trouble making the connection between the skills taught and what I'm trying to accomplish.
I have a static paragraph of text - black on a plain white background. I would like each sentence to highlight with a yellow box behind it as the audio for that sentence is read. I would like a user to be able to hear the entire passage, but also be able to click on individual sentences and hear them separately.
