First, I have this function:
private var file:File = new File;
public function openBrowse():void{
file.browseForOpen("Objekt auswählen");
}
but how can I put the object to a datagrid?
I have a datagrid and there I want to use the editedItemRenderer to access the text, that I just entered. In the debugger I can see there is a text attribute for the editedItemRenderer but when I want to use that attribute the debugger says something like text is undefined...

View 1 RepliesI need to get the value of the item clicked and the name of the columns.[code]But this way it returns 'undefined'.But if I put the name already in function, I can get the correct data, example:Alert.show(''+datagridlist.selectedItem.create); // create is a column name in mysql.But this variable must be created dynamically, example:[code]I'm at it on time and I can not convert the string to column name.
View 2 RepliesI'm trying to put some File objects into a DataGrid, but I can't find a way to display the File.icon in there.
So far I have this: (ms[x] is a File)
listData.addItem({
filename:ms[x].nativePath.replace(/.*\/,""),
path:ms[x].nativePath.replace(/\[^\]*$/,"\"),
icon:ms[x].icon.bitmaps[0]

filename and path are displayed correctly, I just can't get the file icon to show.

How do I export data in my datagrid to an Excel file in Flex?Can anyone provide some examples for that? I am browsing but couldn't find out a single example of that kind.Browsed a lot and found out how to convert datagrid data to csv format. Now How to convert that to excel? Is there a way to do that without using any server script ? Can't it be done in Flex alone?
View 6 RepliesI have a flex datagrid with 3 columns. The first column contains the image name(unique key). The other two columns have username and size details. I want to split the username into lastname, firstname, address and some other stuff. Can we have multiple rows in the grid for one image? Tried multi-line, it works but we need to keep adding spaces and its cumbersome. Since each row in the flex datagrid is represented by one index in the XMLList which is enumerated, is there a way to have more than one row assigned to one image and shown in the grid? something like this.

View 1 RepliesI 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?

From this (normal dataGrid)

How to turn Flex MXML DataGrid into something like Horisontal DataGrid? (may be some how with Flash builder 4?)

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.
[Code]..
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

View 1 RepliesI 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:

step1- I got an xml that is locally loaded(works fine)
step2- the content goes into a datagrid that is displayed (works fine)
step3- In AS3 I dynamically add some lines to this xml file(works fine)
step4- I save it locally (works fine)
step5-and want the datagrid to be updated..(works not-so-well)
So, in step 4, the data is saved into the xml file, but in order to finish the save, the user has to click on the "Save as" windows in order to have the file updated of course.. and that's where's my problem, how can i tell flash to wait till the user actually saves the file, before reload the xml file in the datagrid ? here's the code :

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.

Using a standard Flex DataGrid, is there an easy way to determine the grid row index given the data object or index of the data object in the data provider? On the flip side, is there a way to get the index of an object in the data provider based on the DataGrid row index?
View 1 RepliesI have a TabNavigator, and each tab is a Module. One of the modules is labelled Units and the full code of the module is posted in this post. There are several problems:
1) Forms are not populated with data from the datagrid selection.
2) Selecting a row and clicking delete gives the very-common error: TypeError: Error #1009: Cannot access a property or method of a null object reference.
A trace on the valueObject unit within the selectionChangeHandler function gives NULL. Why? Note: In other modules (other tabs of the TabNavigator), I have DropDownLists populated with units. This means that the valueObject Unit is defined in the other modules. However, valueObjects should be private to modules, and not shared.

But if i start scrolling the entries are repeating in the cells using the renderer. The cells are not filled with date according to the id. What mistake i'm doing here.
I read a lot of the explainations like:
