Flex :: Compare Data From DataGrid DataField With String Value?

Feb 16, 2012

The question seems to be simple, however it create problems for me. I have a dataGrid with two dataFields: peerID, name. The information in a grid updated dynamically when new user joined the group (I'm creating a chat). I need that information about user deleted from a grid after it's disconnect. So, on "NetGroup.Neighbor.Disconnect": event i want to compare "event.info.peerID" value with all peerID values in a grid and delete info about disconnected user.

I'm trying to use next construction:

for (var i:uint, len:uint = txtDataArray.length; i < len; i++)
{
if (txtDataArray.source[i] == event.info.peerID)
{

[code]....

But it doesn't work at all!

I'v noticed that construction txtDataArray.source[i] (or txtDataArray.getItemAt(i) ) returned [object GridColumn] insead of value. So, I have two questions:

1) How to get the value of exact cell?

2) How to organized info delete after user disconnect?

Flex :: Settingflex Datafield With A Function?

Feb 6, 2010

I can't seem to get this right and everything I read is kind of like my problem but not quite. This seems like it would be pretty easy. All I want to do is set the value of a datafield using a function. I call in an xml file and can set the value of a datafield from that xml (in this case it's a category id as a number). But then I want to translate that number into a name by correlating it with a different data array.

so basically i just need to pass the catId into a function in the datafield but can't get it to work.

<mx:DataGridColumn color="0x00101F" textAlign="center" editable="true" id="categoryField" headerText="CATEGORY" dataField="getCategoryName(@catId)" editorDataField="text"></mx:DataGridColumn>

Flex :: Flash Builder - AdvancedDataGrid DataField - Use A Subarray Or Object?

Aug 5, 2011

I have an advanced data grid in flex (flash builder 4). It's dataProvider is pointing to an ArrayCollection (this._encounters). Inside that array collection is a property that is an object (a client object).

I tried setting the dataField to "clientObj.firstName" to refer to the first name property within the clientObj property of the this._encounters array collection. It did not show anything. So, I added a labelFunction to that column (code below) to set the text in the cell. This works fine and now I have values showing in the grid.

The problem is now when I click the title of column to sort it. It throws an error that property clientObj.firstName is not found in my array collection!So, is there a better way to set the dataField / source for a column and point at a property in a sub-object -- or a way to fix the sort?

Below the first column

<mx:AdvancedDataGrid x="0" y="25" id="adgEncounters" designViewDataType="flat" width="100%" height="100%" dataProvider="{this._encounters}">
<mx:columns>
<mx:AdvancedDataGridColumn headerText="first" dataField="clientObj.firstName"

[code]....

In the mxml above, this is the changed line - notice the stringSortByField added:

<mx:AdvancedDataGridColumn headerText="first" dataField="clientObj.firstName" sortCompareFunction="{stringSortByField('clientObj','firstName')}" labelFunction="encounterGridLabelFunct"/>

If it were a numeric field use the numericSortByField. If it were a date string from a database, use the dateSortByField function instead.

Flex :: Datagrid Selects The Wrong Custom Cell In Datagrid

Mar 15, 2010

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;

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 :: Getting A XML Attribute Using Variables?

Oct 21, 2011

I wish to extract an attribute from an XMLList and assign it to a string. Here is the snippet of the XML

<node>
<sport GAME="Squash" TIME1="2" TIME2="3" TIME3="8"/>
<sport GAME="Table Tennis" TIME1="4" TIME2="6" TIME3="7"/>
</node>

I have two variables. One variable will contain the game type, either Squash or Table Tennis. The other will contain one of the following strings "TIME1", "TIME2" or "TIME3". The variables are called game and time. I have tried many variations on the code below to get the needed attribute but with no joy.

var result:String = node.sport.(@GAME == game).(attribute(time));

Flex :: Get Hyphens In Attribute Names?

Mar 23, 2010

Flex has an issue with hyphens in xml. I need to generate an xml object with hyphens in the attribute for a Google Checkout implementation.

I can get away with:

var xml:XML = <item-description/>;

and

var xml:XML = <item-description the-name="foo"/>;

but what I need to do is set the value of an attribute like this:

var timestamp:String = methodToGetMyTimestampString();
var xml:XML = <item-desc/>;
xml@start-date = timestamp;

but I can't do that. Since flex doesn't like the hyphens, I don't know how to get or set attributes with hyphens in the name.

Xml :: Flex Tag Attribute Value / Property Parsing?

have an RSS feed, within Flex I have connected to the feed via HTTPService, the XML structure is as follows (not exact, but for the purpose of the question). I am able to walk down the xml and access the data within the title and link nodes with success but when I get the the description node and try to access the img and src attributes within it, I haven't had any success. Reading about parsing with e4x the example I get is:

var xList:XMLList = xData.channel.item.description.(attribute("src"));
or
var xList:XMLList = xData.channel.item.description.(@src);

AS3 :: Flex - Test Existence Of Xml Attribute?

Jan 13, 2011

What is the best method to test the existence of an attribute on an XML object in ActionScript 3 ttp://martijnvanbeek.net/weblog/40/testing_the_existance_of_an_attribute_in_xml_with_as3.html is suggesting to test using

if ( node.@test != node.@nonexistingattribute )

and I saw comments suggesting to use:

if ( node.hasOwnProperty('@test')) { // attribute qtest exists }

But in both case, tests are case sensitiveFrom the XML Specs : "XML processors should match character encoding names in a case-insensitive way" so I presume attribute name should also be match using a case-insensitive comparison.
