Like we have rendererAdd function/hook for a Spark List which is dispatched when an itemrenderer is added to the container? Do we have any similar method/hook at DataGrid level also?
View 1 RepliesIs there any function (or any easy way to implement it) equivalent to calculateDropIndex for spark's DataGrid?
(using Flex Hero 4.5.0.19786)
I am searching for something like CellClick event on Spark DataGrid, or something alike.
Is there something like this in Flex 4.5, and how to get the data from the clicked cell ?
Is there a way in spark datagrid to disable some rows programmatically, in flex 3, it could be done using the function mouseEventToItemRenderer this way:
override protected function mouseEventToItemRenderer (
event: MouseEvent): IListItemRenderer {
var listItem: IListItemRenderer;// = super.mouseEventToItemRenderer(event);
[Code]....
And then I implement the function disabledRow to return true or false depending on some condition, the condition that will specify if the selected item will be renderered or not. Is there a way in spark datagrid to do the same?
Is it possible to set a tooltip just on the header of a spark datagrid. I do not want any tooltips on the data - just the header. I have played with mouse over and this sort of looks like it might work. This seems a bit of a hack to me though.

View 2 RepliesI want a spark datagrid that allow a user to input numbers only. They can only input number with up to 5 decimal places. I am struggling with this in Spark. I can do it in Flex by using the itemEditEnd parameter of the MX DataGrid.
How do I do this is Spark? Any pointers would be great.
Recently I am working with Spark DataGrid. Before I was using AdvancedDataGrid. In that I was capturing itemDoubleClick event. But I am not able to find such a event in SparkdataGrid. So I want to capture double click event on single row of DataGrid. Some people told that, I have to use my custom ItemRenderer to do that. But is there any way to capture itemDoubleClick event in Spark DataGrid without creating custom ItemRenderer ???
View 1 RepliesHow can you display a multi-line column header using the Flex Spark Data Grid for Flex 4.5?
View 5 RepliesI am unable to find if the spark DataGrid supports moving / reordering the columns. If not what could be the best solution? Maybe using the mx version?
I want the user to be able to drag the columns and arrange them.
The checkboxes are updated correctly when I select one or more datagrid rows but when I select a checkbox for the first time the checkbox does not refresh until the pointer moves out of the datagrid row. How can I fix this?

I have a custom skin applied to a Flex 4 spark datagrid. One really annoying issue I am having is finding the ability to override or change the selected row border color. I was able to set the selectionColor just fine but the border is still the default light blue color. I need it to be yellow.
Anyone know where I can find this style or override this border that is being set when selection happens within the skin itself.
I almost got it, but the part that's giving me trouble is making the header background transparent. I am making a custom MXML skin based on the default Spark DataGrid skin. I tried setting the contentBackgroundAlpha to 0 on the columnHeaderGroup and the headerRenderer, but that didn't work. I tried setting visible to false for either of those, but that made it so that the text didn't show up either, so that didn't work. There is no setting for backgroundAlpha in either of those two, so I'm not sure what else to try.

View 1 RepliesFirstly sorry for the really lengthy question. I am trying to implement an Org.Chart using spark DataGrid. The data for the Org.Chart does not change and hence I am hard coding the values. I had to implement this Org.Chart as I need to have floating Nodes and also the connecting lines should be drawn a bit different when compared to using an external component. Please find the following image of which Im trying to achieve: Here is the idea:

Flex 4.5+ is I guess everyone is working on nowadays so I asked this question since I haven't yet find working both spark datagrid and the mx printdatagrid components together.
What I'm trying to achieve is to print all the data inside my spark datagrid. So when I do my research, we use the PrintJob or the FlexPrintJob classes.It works fine but when I need to print multiple pages since the data on my spark datagrid is quite long, I can't somehow find a way how to do it.The print output is only upto where the height of my spark datagrid.So in my research, they somehow managed it to use the mx:PrintDataGrid component.But sad to say, they did it with an mx:DataGrid also.how to use the mx:PrintDataGrid along with s:DataGrid.
var printJob:PrintJob = new PrintJob();
if (printJob.start())
{[code]....
If converting a spark datagrid columns to the mx datagrid columns is not possible, is there a way that I can print all the data on the spark datagrid using multiple pages?
does anyboy know if Flex 4.5 Spark Datagrid suppoprts multi-column sort natively - just like the ADG does?
View 2 RepliesI have a question about the Spark DataGrid and how it works in terms of garbage collection. What I'm finding is that if I dynamically add and remove columns from the DataGrid at runtime, the GridColumns and ItemRenderers never get freed from memory.
For instance, if I have a list with 10 items and I create 10 columns, there will be 100 ItemRenderers and 10 GridColumns. If I remove all of the columns, they are still there.

View 1 RepliesI am trying to find a way to Scale (either font or scaleX&Y) a DataGrid (with equestedMinRowCount = requestedMaxRowCount = requestedRowCount = dataProviderLength), so that it would Always show all the Rows (so no scrollers).Solution I came up with for Scaling is:

I would like to have a spark datagrid that wordwraps all rows where relevant. At the moment it appears like the width of a cell is dependent on the contents of the first row and then subsequent rows are word wrapped. For example:
[Code].....
How can I get the datagrid to dynamically resize to 100% of the container width and for wordwrapping to happen on all rows? (not just rows after row 1)
Is there a way to get the columns to resize to the width of the new Datagrid instead of overflowing and showing the scrollbar? I've tried on the skin, setting all relevant properties and ran out of options. I just want it to behave like the previous Datagrid where the columns would resize to the width of the datagrid.
View 1 RepliesI'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.
I have a spark datagrid with selectionMode="multipleRows".
I have three columns in the datagrid. I don't want the row selection to happen when the user's click falls on the third column of a row.
The row selection should happen only when one of the first two columns is clicked. How do I achieve this? There is a selectionChanging event for the datagrid, but the GridSelectionEvent object received in the handler does not seem to provide any information about the column on which the click happened.
I have a spark DataGrid component with several columns and I want to have my application default to descending order on the first column in the DataGrid. I would like to use the built-in default sort that occurs when clicking the top header once. I have no need to sort the ArrayCollection I'm working with or change what the comparators are.I also want any user-generated sorting such as clicking on a different column's header to override the default sorting.
View 1 RepliesIn the Spark DataGrid the default row height is about 22 px. I would like to set the default row height to 18 pixels and I can do this easily enough with the rowHeight property but what happens is when the rowHeight is set to anything less than 22 px the bottom area of the text in each row is cut off. It seems that the default grid itemrenderer or grid label has a min height set to it. Since I have multiple columns and want to have shorter rows but not have the bottom of the text cut off in each row how would I do this?
View 2 RepliesI have a spark datagrid on a mobile application, I set the
interactionMode="touch"
and the dataGrid scrolling is good, I got some problems adding a selectionChange eventListener to it, because scrolling the dataGrid will automatically change the selection and instead simply scrolling it, the function binded will start...
How can I add the touch dalay before select the index, so if I scroll the grid the selection won't change, and it change only if I press the item without scrolling?
I am having an issue with my ItemRenderer, which I am using for a spark List. My code is the following:
I have this list:
<s:List
id="productSetList"
dataProvider="{ model.productSets }"
[Code]....
The thing is, if I scroll the list, and click on an item, it does not trace 'arthur' ! Why is this so ? I must trace that all the time that someone clicks in the list!
EDIT: If I remove change="model.selectSet( productSetList )" in the list, it works!! but I cannot remove that, some suggestions ? How can I switch that to another function?
I have a main application that contains a list, using a custom itemRenderer to display data.
I would like to be able to call a function, inside the itemRenderer, from the main application.
When running the app, we have a list with three persons, and a button. I want to call the function myItemRendererFunction() inside the itemRenderer, of the selected item in the list, all this, from the main app.
