ActionScript 2.0 :: User To Add / Remove A Row Which Would Increse / Decrease The MyDataGrid.rowCount Of The Datagrid
Aug 24, 2005
Ive got an editable datagrid, and the size allows 16 rows. It is possible for the user to add/remove a row, which would increse/decrease the myDataGrid.rowCount of the datagrid. However, whenever a row is added/removed, the rowCount remains the same (16, which it was created with). Is there another built-in variable other than rowCount that can gauge the ACTUAL rows in the datagrid, not just what it was created with?
I 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:
protected function thisDatagrid_resizeHandler(event:ResizeEvent):void { if (event.oldWidth < this.width) {
Rows B, D and E do not sort correctly, basically because I am assuming they have numbers with unmatching or too many places. I can not find any help online with this. The columns with percentages work fine unless they go over 99%. ?[code]...
I have a game with a big raster map.Now we are using jpeg (4900x4200)And durring the game we need to scroll through this map.[code]In windows, we have very good performance.In Linux and Mac in flashplayer we have a good performance too.But in browsers performance is quite slow!
I'm using the TileList in a Flex 3 website. I need to set the rowCount and columnCount to factors of the total number of items in my array. For example, let's say that there are 15 items in my array. Then, I'd like to set the rowCount to 3 and the columnCount to 5 (3x5=15). Or if I had 16 items in the array, then I'd like to set the rowCount to 4 and the columnCount to 4 (4x4=16). The problem is that the length of the array varies. It's pulled from a database.
I have a datagrid from which I'd like be able to remove rows at will. Below is the component item renderer I'm putting together in order to achieve desired result, but there has to be a better way to access the data provider of the "parent" data grid.
The tree should have a minimum row count of 4 and a maximum of 10 (beyond which it should display the scroll bars). So, I have a tree with rowCount="4" and I want rowCount to change up to "10" depending on the currently expanded nodes. In debug I can see two of the tree's properties which I could use[code]...
But these are not accessible from outside so I can't find a way to understand if the tree is expanded or not.
- I have a sample online store with products & numeric steppers so the user can select the quantity the want. I want to display their selections into the flash datagrid so that upon checkout they can see the products chosen.
-I have several columns for the datagrid, "Quantity, Product, Price, & Total". I want to display the items chosen in their corresponding fields however, the way I have set up my code all of the items are appearing in the one column.
How remove the scrollbar from the datagrid to display a list that it grows as large or small like the list size? And how to appear the scrollbar in the stage?
How can I make datagrid height is equal to data content in Adobe Flex however suggested answers did not work for me.The blank row at the end of the DataGrid does not display at first, until I begin editing editing the last row, at which the entire grid is immediately pushed upwards, making the top row disappear and the blank bottom row reappear.
How 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?
which is great because it shows how to add columns to a datagrid, but how do you add and remove rows to the datagrid?I'm trying to I'm trying to come up with a Character Generator for our Tabletop Wargame (see hereand rows to appear when you say click on a Weapon like Fist and then onto another weapon (Fist only works atm as a demo).ie how could i format it so it was like a table (because at the moment the Fist stats are formatted with spacebar spaces), and how could i make it so that when you choose your 1st weapon it appears 1st in the table (say a Bow), and when you click your 2nd weapon it appears 2nd in the table (say a Sword), etc...
I've been trying to remove all data from a datagrid to avoid having the old values plus the new values all the time but it doesn't seem to workI feed a datagrid from a xml and each time I try to load a new one, it simply adds to the previous.
I tried: myDatagrid.removeAllColumns(); myDatagrid.dataProvider.removeAll();
How should I go about matching the selected row of a sorted DataGrid to its source data row within its associated data provider?
For example, once a user sorts a DataGrid by clicking on one of the column headers, the target.selectedIndex from the CHANGE event (generated next time a row is selected) represents the index of the sorted row and not the index of the data as supplied by the data provider. Is there a simple way to map the index of the user selection back to the index of the original data?
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)
I am loading the data externally from xml and displaying in a datagrid. I have 2 buttons addRow and deleteRow. My datagrid headertext names are "name" "age" "rollno" "image", where image also will be loading externally thru an xml file.now when i am pressing the deleteRow button, whole row is getting deleted but an image icon is still appearing under "image" headertext. It was not an actual image but a blank image icon kind of thing is appearing, how to remove the icon. i want my whole row to be deleted. but its not happening.
I am using an mx:DataGrid with a dataProvider to display Rows. I have checked the no of rows in my array ( which is 8 ) and the no of rows in the dataGrid. They both match, however I always get an extra blank row at the end of my data grid. How can I remove this row?
Is it possible to remove the horizontal separator which divides the headers with the data? I managed to remove the vertical ones with mx.skins.Programmatic skin, but could not find a way to remove the horizontal separator.
I have a data grid in one frame, then upon moving to the next frame use removeChild to get rid of it, which works fine.But it seems to leave behind the keyDown handler that is naturally part of the component (which is used to navigate the rows of the datagrid).Is there any way to get rid of this?The first time (and only the first time) I press the up or down arrow key in the next frame which does not have the grid, I get the following error:
TypeError: Error #1009: Cannot access a property or method of a null object reference. at fl.controls::DataGrid/drawList()[code]...........
I thought about a form in flash for a cooking site for example where the user can send their own receipes via an email form. So for example like this:
Name: Email: Ingredients (separate by comma): Step 1: Upload Image:
I am asking if it would be possible to have a liitle "+" sign or any other kind of add button behind the "step 1" field and by clicking on it the user can add a new field labeled "step 2" and so on.... same with removing if he accidentially adds a field that is not required....I have a flash form that gots a validation and image upload function, I only need to add the "add /remove" field function....
I'm trying to make a Flex (Advanced)DataGrid component with some mechanism where the user can toggle the visibility of the columns. I've crudely implemented this by reading in the columns into the right-click menu, and when a column name is selected here, the visibility is toggled. It works, but it's not the most elegant solution.Specifically, I'm trying to emulate the "datagrid" that Mozilla Thunderbird uses to display emails. Here is an image:
In the upper right, there is an icon over the scroll bar. If there is no scrollbar, the icon remains in the same place. When clicking the icon, it opens up a menu that shows all the possible columns, with the visible ones having a check mark next to them, like this:
Also, the scroll bar always appears under this button, never "pushing" it over into it's own column.I'd like to re-create this in Flex. I believe the menu part and creating a column with a button headerRenderer is easy enough. But I can't figure out how (if at all possible) to do this with the scrollbar, because the scrollbar always seems to be "its own column".
I am trying to build a website, and here is the logic behind my problem. I have 2 button, when user clicked on button 1 i load movie clip from library with: _parent._parent.cont.attachMovie("Page1", "e", 0, {_x:-265, _y:-250}); when user clicked on button 2, i load other movie clip. Problem: i want remove last movie clip after user clicked on button 2 and then load new movie clip but i cant...
I'm new to AS3, as well as this forum,and had a question. I created a simple ad-lib type game for practice and would like to be able to remove any leading and trailing whitespace that a user inputs from the final outputted ad-lib, as well as if the user tries to submit their input with missing fields of text, it would throw an error and ask them to try again.[code]...
I'm using flex 4.1 to write an application. i read in the documents that has the rowCount property to set how many items to display. the does not have that property. how can I limit the list to display 3 items ?
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 :
I am in search of finding a way to display shopping cart items in a flash 8 datagrid in the order it was chosen by the user & also to ability to delete an item if the user choses. Currently I have the items displaying however they are displaying in a position as it is stored and called in the array. [code]
