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 :: Get A Custom ItemRenderer To Scroll The DataGrid Rather Than Its Cell?

Jun 2, 2009

I'm having an issue with a custom ItemRenderer I've written for a DataGrid. With this ItemRenderer, it's possible that the contents could exceed the width and height of the DataGrid cell - and when this happens, scroll bars appear, letting me scroll the individual cell.What I would like, however, is that when the contents of the cell are too large, the entire DataGrid scrolls, rather than the individual cells.

Now, when I set the custom ItemRenderer's horizontal and vertical scroll bar policies to "off", I get the vertical scrolling on the DataGrid that I want (the individual cells stretch to accommodate the full height of the contents) but I don't get any horizontal scrolling. Instead, any content too wide for the cell is clipped. Incidentally, setting the DataGrid's horizontal scroll bar policy to "on" has no effect, the scroll bar gutter is drawn, but nothing scrolls Is there a way to force the DataGrid to scroll horizontally when my custom ItemRenderer's contents are too wide for the cell?

Actionscript 3 :: Datagrid Cell Render With Custom Component?

Get Content Of A Single Cell From A DataGrid In Flex 3?

Mar 19, 2010

I want to select information in a single cell from my DataGrid in Flex 3.

Specifically, I'm displaying three phone numbers per line and the user needs to be able to select one of those numbers, from any row, but not the whole row.

While similar to this, I am displaying the DataGrid to the user. The answer for that question was to manipulate the dataProvider, how can I know what cell I've selected in order to do that?

Flex :: Trying To Get Text In Advanced DataGrid Cell

Jan 6, 2011

I have an AdvancedDataGrid that loads data from a web service. It only loads the top level stuff and then as you click the arrows it gets that data. All I want to do is to find out if some text is in one of the cells. I originally did this:

public static function assertTextInAdg(params:Object):Boolean{
// Gets the ADG
trace('youre in the assertTextInAdg function');
var grid:* = FPLocator.lookupDisplayObject(params);
trace('var grid:* = FPLocator.lookupDisplayObject(params): ' + grid);
[Code] .....

And then it fails, because it can't get the source, I think. I am completely open to other strategies and I have been stuck on this problem for 10 days now. This seems like it would be relatively easy. I have been going down a slightly different route. I am now trying to iterate through the HierarchicalCollectionView with a cursor. This seems to work. But, when I get the node I can't do anything useful with it... I have been looking for examples but so far they all stop at the point of getting the node.

public static function assertTextInAdg(params:Object):Boolean{
// Gets the ADG
trace('youre in the assertTextInAdg function');
var grid:* = FPLocator.lookupDisplayObject(params);
trace('var grid:* = FPLocator.lookupDisplayObject(params): ' + grid);

Flex :: Show Red Error Border On DataGrid Cell

Apr 27, 2010

I can successfully add a validator on an item in my datagrid, by passing in the particular element in the dataProvider to the validator, but I can't get the red border to show up around the cell if the validation fails. I have stepped through the validator, and confirmed that it is passing back a failure, but I can't figure out why the red error border doesn't show up. I have a feeling its because I am passing the item in my dataProvider as the validator source, rather than the 'cell' item, but I can't find a way to access the cell.

Flex :: Get A Cell Value Of A Selected Row In A Mx.dataGrid In Flash Builder

Feb 19, 2012

I thought I could use...

studentID = myDataGid.selectedItem.studentID

Does not want to work for me. Tracing the expression in debug it is returning "XMLList (@11e55e8d1)".

The datasource is an XMLListCollection. tracing the expression myDataGid.selectedItem I can see the studentID node and it has a value.

I see that starting with Flex 4.5, Adobe recommends that we use the spark.components.DataGrid class as an alternative to the mx:dataGrid which I am not at all familiar with or where to start to learn. I have this mx:dataGrid all setup and otherwise working and would prefer not to have to learn something new.

Actionscript :: Change The Style Of One Individual Cell In A Flex DataGrid?

Jun 13, 2011

I have a Flex DataGrid where one individual cell needs to be rendered in a different way from others. Specifically, for one row of the grid, one of its cells should be hidden.

The DataGridColumn is set out like this in my .mxml file:

[Code]...

but that doesn't work - in fact it messes up the display in a rather entertaining fashion (one of the other cells in the row gets an extra checkbox.. I suspect it may be possible by using a custom ItemRenderer class but that seems like a lot of code overhead for a fairly simple case.

Flex :: Binding ArrayCollection Result To DataGrid

Jun 29, 2010

I am trying to bind an ArrayCollection result coming in from the server to my DataGrid
created dynamically in AS. The result data is not getting Displayed in the Grid.
var dg:DataGrid = new DataGrid();
dg.width=650;
dg.dataProvider=someArrayCollfromServer;

I am adding the dgColumn as runtime based on some data from a XML and it is the same as defined in below static format. But if I use the same code and create the DataGrid as a Flex Component as below, it works fine.
<mx:DataGrid id="dg" width="100%" height="100%" dataProvider="{someArrayCollfromServer}">
<mx:columns>
<mx:DataGridColumn dataField="Value" headerText="Value"/>
<mx:DataGridColumn dataField="Code" headerText="Code" />
</mx:columns>
</mx:DataGrid>

This works fine. Is there some functionality or implementation different as far as DataGrid is concerned in Flex and AS.
