I have a black row separator and a grey column separator, but because the row separator gets rendered first, the column separator appears over the top of it, causing what appears to be breaks in the row separator. Is there any way to change the order these are rendered to prevent this?
View 1 RepliesI've set a DataGrid to display all the rows in the data provider by binding it to the height of the control.Now that all rows are rendered, I want the DataGrid to grow horizontally so that every column renders the whole text (of Labels).Is there a way of doing this without resorting to a typical object?
View 1 RepliesA few hours ago I've asked how to create a custom component (textInput and label component and created a Component Definition) and with your answers I can do that now.
Problem 2: I'd like to use that component in a datagrid column so that the user can type a value in the textInput which will in turn update the underlying dataprovider. I know I should use a cellrenderer like I've done with a checkbox column
I have a DataGrid where some number of the columns can have a labelFunction. The nature of the labelFunction result can change problematically(eg apply formatting,bypass formatting. How do I get the DataGrid to re-render the visible items so that the labelFunction will be run again to get the new data.I've tried the invalidateDisplayList, validateNow, and tried dispatching ResizeEvents on the DataGrid.
View 1 RepliesHow do you remove the header row from a Spark DataGrid? MX DataGrid had the attribute "showHeaders" but this doesn't seem to be present in the Spark DataGrid.
This seems like it should be a very easy task, so either I'm extremely dense or just missing something? Do I have to create a custom skin for my DataGrid and remove the header parts? That seems like overkill or is it the Flex / Spark way?
Is there any function (or any easy way to implement it) equivalent to calculateDropIndex for spark's DataGrid?

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 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.

The data for the Org.Chart does not change and hence I am hard coding the values.

I would like to make the height of my DataGrid rows a bit larger than the default. The problem is that the text is vertically align to the top of the row. I would like to vertically align it to the middle of the row.
Is there a way of doing that via CSS or Skinning in Flex 4.6? note that I am using a Spark DataGrid and not an MX version.
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.

I am trying to use the same custom renderer for all the columns in a spark DataGrid. I need to know the dataField or columnIndex based on which I can change state in my custom itemrenderer.
Earlier in mx:DataGrid, this can be achieved by extending the MXDataGridItemRenderer which implements IDropInListItemRenderer and hence dataGridListData property is available.
But using the spark DataGrid, I am extending the GridItemRenderer which DOES NOT implement the IDropInListItemRenderer and hence unable to access dataGridListData property. I have tried to write an action script class extending GridItemRenderer and implementing dataGridListData but flex throws an error in the set function of this variable.

I'm using the Spark DataGrid for the first time and finding it generally very usable.There's something I'd like to do with the contents of my grid now that I've drawn it though and I'm a bit stuck as how to proceed.I'd like to make a function that runs through each cell of a certain column in the DataGrid, that checks each value against an Array of predefined values; if it finds a match, it should then highlight the cell as conflicting, by changing its colour.I know you can access a particular cell's item renderer, by using the getItemRendererAt() function, and passing the column and row indices. But I can't see how I would, for example, loop through the values in each column
