Actionscript 3 :: Scroll Bar To Appear When The Content Is Too Tall, And Have The Same Skin For The Background As The DataGrid?
May 16, 2011
I'm trying to create a layout not too different from the feed reader sample.The problem I'm having is that I'm finding the documentation unclear. There are so many different types of layouts that I don't know which one to use when.In the example, on the right side there are a few horizontal panels:
[feedToolbar(HboxPane)]
[feedItemsGrid(Datagrid)]
[filterToolbar(HBox)]
this does not include the details panel and the resize handle.I would like to swap the DataGrid with my custom content which is basically a sprite. The problem I have is that I cannot just include a sprite, because it does some funky resizing. I would like the scroll bar to appear when the content is too tall, and have have the same skin for the background as the DataGrid.

I use a flex mx:datagrid. I can set the headerBackgroundSkin to specify a skin or a picture to be displayed in all datagrid column's headers and it works just fine !
The problem is I can't find any way to specify a custom skin for the currently sorted column (doesn't matter if the sort is asc or desc, this is just to show the user which column is currently sorted).
I also tried to create a custom headerRenderer for each column but it is quite complicated and doesn't work very well.
I have been looking for the solution for a while but I can't find a good approach to do it. It sounds like a very basic need for me...incredible it is so complicated to achieve with Flex !!
I noticed someone was looking for the same thing few years ago but without success... [URL]

autoscroll functionality in Flex2's DataGrid while dragging an element row in it. Is there such a functionality or not?
I mean, I have a DataGrid which contains a collection of rows. The collection is longer that the DataGrid could fit, hence there is a vertical scrollbar that allows to get to the rest of rows. I have enabled the functionality of moving-by-draging to be able to change the order of rows in the DataGrid (see the simple code below).
Now, let's say I want to move the first (topmost) row to the last (bottom) position of the collection. When the top row is displayed, the bottom one is not visible (not without moving the scrollbar). So when I drag the top row, I cannot drop it beyond the few currently visible rows. Surely I could drag a bit and then scroll to bottom and then drag a bit more, but that's not the point. The point is - is there a functionality of autoscroll implemented in Flex2 DataGrid, where the collection would scroll itself automatically to allow one to drag beyond the few visible rows?
In Adobe's official PDF document "Flex2 Developer's Guide", section "Using drag-and-drop with list-based controls" I've found this sentence:
Quote:
If the control has active scroll bars, hovering the mouse pointer over the controls top or bottom scrolls the contents.
Well, it suggests that there should be this functionality I ask about. But it doesn't work for me.
Here's the simple code that builds the DataGrid in Flex2, that fails to autoscroll, if you care to check it:

I m using FLASH CS3, I used Datagrid and Combobox component from components panel, and simply add some data inside in that.
setupComboBox();
function setupComboBox():void {
cb.setSize(200, 22);
cb.prompt = "Select a Credit Card";
cb.addItem( { label: "MasterCard", data:1 } );
[Code] .....
It seems working fine. My problem is, I want two different type of skining of two different component (DataGrid & Combobox). in the same fla. E.g if datagrid have gray color skin type and combobox have black color skin type.

This is for a scroller, I've been trying to figure out why it's pushing a particular movie clip off stage for a particular clip, when the others are working fine. Tracing the numbers, the clip is off at y -76000 and Flash thinks the height is somewhere in the neighborhood of 20 million, 20133131.85 to be exact.

Is there any way to scroll Datagrid on timer basis.Let say there are plenty of records which can not be shown in one screen. And the screen is showing the first 10 records. An auto scroll should start after 5 seconds and bring up the next 10 records. Then again after 5 seconds the other 10 records and so on. A kind slide show effect.

Is there a way to make the datagrid scroll if it's width exceeds it's parent container (instead of making the parent container scroll?) I have a datagrid with a fixed column, and of course I want the scrollbar to appear for the datagrid and not the enclosing HBox. I already set minWidth of the HBox to 0, tried autoLayout=false, but with no effects. The datagrid is dynamically created in AS3, so the enclosing container.
Maybe I did not express my needs clearly - the content of the datagrid should not be wider than the datagrid itself. I just want to surrounding Canvas of the Datagrid to not have any scrollbars and let the datagrid itself scroll. But just setting the scrollpolicy to off on the Canvas will not yield to scrollbars on the datagrid, it will rather clip the data.

I have a custom <mx:DataGrid /> that is updated with data from a ColdFusion server every 60 seconds. I've noticed that every time the DataGrid updates and redraws the scroll position is reset to the top.
Is there a way I can preserve the scroll position for my DataGrid?

I have a datagrid with more than 70 columns (with few fixed). I dont want the scrollbar to appear in datagrid (both horizontal and vertical) but in the parent container which is a VBox (or canvas) instead. This will help to scroll the screen vertically without having to scroll all the way right in datagird to scroll vertically.

I have 2 questions: 1. What would be the event to capture the fact a scroll has taken place in a datagrid?
2. Does anyone have any suggestions on how one could disable the scroll of the datagrid when a user clicks a cell then drags out of the datagid?

I've noticed that the default behaviour for a DataGrid's vertical scroll bar is to scroll one row at a time. This is all well and good when the rows are all uniform and small (e.g. displaying a single line of text), but gets really ugly as soon as you have rows with variable heights.I'm curious, is there a way to make DataGrid scrolling "smooth"? For instance, is there a way to have the DataGrid scroll by a set number of pixels, lines of text, etc. rather than scrolling one row at a time?
So far, the only solution I've managed to come up with is to place the DataGrid in a Canvas and have the Canvas do the scrolling instead of the DataGrid. The issue with this approach, though, is that as soon as the Canvas scrolls far enough, the DataGrid headers scroll off-screen. Ideally, I'd like to get the smooth-scrolling nature of the Canvas, but also keep the DataGrid headers visible.

I am performing a find operation in a datagrid on one of the columns. After I find the row containing the item, I make that as the selected index row, which highlights it. But now I also want to scroll the datagrid down or up (if the item is out of screen scope) to show that selected item automatically on this find operation.

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?

I am very new to ActionScript and Flash development so excuse any incorrect terminology that I may use. I'm developing on Ubuntu, using AS3, and compiling with the flex sdk using the ANT tasks (flexTasks-4.0.0.10485).I am looking for a way to scroll content within a sprite. So, say I have a sprite that is 100px in height, and I add several child objects stacked on top of each other that exceed the sprite height, then I would like to display a scrollbar to enable scrolling through the children.Now I found fl.controls.ScrollBar, but when I attempt to import the class I receive the error:Error: Definition fl.controls:ScrollBar could not be found.I'm not sure why I am receiving this error, as this appears to be a valid AS 3 component according to the livedocs.Is there a scrollbar component in AS 3 that can be attached to a display container like a sprite?

I have a combobox and a datagrid that are both populated by an xml. The combobox works perfectly. The datagrid is loading something cause the auto scrollbar comes up and is longer or shorter depending on what category I select from the combobox. For some reason the datagrid simply isn't displaying any text. I'm sure it's something small that I'm overlooking, but I just can't find it.[URL]

SkinParts are a great way to add event handlers and logic to an object that is instantiated in the skin, away from any business code. Often, though, I find myself wanting to do the opposite, and define parts that will be used in reusable, skinnable containers in the parent mxml files which will be inserted into the skinned containers.
What's the best practice for when you want to be able to define a control and a skin which can be reused with different controls inserted from outside the skin? Edit: A better way to put this might be that I want to use something that works a little bit like a SkinnableContainer, but that isn't limited to one area where content can be placed.

I have a very strange problem in a Flex 3.4 Datagrid. One of the columns is a ComboBox - I have my own custom renderer for the ComboBox. I use it to select my data and then make a "save" to the db. Upon return the comboBox loses its value. Even stranger is that when I scroll the datagrid area to the left (by moving scrollbar right) - the values in the ComboBox change!! When I scroll the datagrid right (by moving the scrollbar left) - the values in the ComboBox don't change.

I have a movieclip that loads a scrollpane onto the stage. In that scroll pane I have some dynamic text boxes and some buttons. I cannot figure out how to reference those buttons or text boxes. For example, the instance name of the scroll pane is TAQ_Score then the content loaded into the scroll pane is TAQ_Score_Sheet. Then the instance name of the text box is TAQ_Score_Name.
So I assume the reference should be something like: TAQ_Score.TAQ_Score_Sheet.TAQ_Score_Name.text = MyVariable;This reference works fine outside of the scrollpane, but not when I put it into the scrollpane.
