ActionScript 3.0 :: Restrict Editable Datagrid Values In Flex?
Dec 21, 2010
I have a datagrid in flex and i am making the datagrid as editable. I can able to edit it and enter the values. so far so good. Now my requirement was, i want to restrict the editable datagrid cell to some max chars like 10. I mean to say maxChars = 10, i want to restrict like this & i want to implement like this.
I realize that ItemFocusIn is somehow only applicable to editable datagrids in flex,nevertheless I want to fire an event anytime the user selects a new row in a non-editable datagrid. I have successfully used the CLICK event, but this event is not fired when the user uses the keyboard to select a different row in the datagrid. What do I have to do to cause an event to fire whenever the currently highlighted row in the datagrid changes, regardless of weather it was changed by the mouse or by the keyboard?
All i have a flex editable datagrid. By default if i press the left navigation arrow key , it moves to the left but not to the next cell. I would like to override the keydown event such that if the left navigation arrow key is pressed down i set the focus to the next cell on the left.
In short the user needs to be able to navigate using the keyboard through the cells using just like in excel(currently the arrow keys move between characters within a cell).
I'm using a Flex datagrid where only 1 rowItem is editable. All the other row items are non editable. When I edit the value of the row, and press ENTER or TAB the focus is send to the next editable item in the datagrid. In this case the editable field on the next datagrid row.
I don't want this standard behaviour... I don't want the focus to be processed to the next editable item. Since the data is saved instant, it's quite strange that the focus is given to the next field. The focus has to be remained on the item that was edited.
I have an editable datagrid, whenever I make a change it automatically gets saved. How can I disable this? So the changes gets saved only when I click on an external save button.
I have an editable datagrid. If sorting is applied by clicking any header of datagrid, it works fine. But after that, if data values are changed in any row of datagrid, sorting is applied automatically. How to prevent from this behaviour? i.e. sorting should only be applied if user clicks on any header of datagrid and sorting should not be applied when user modifies data in grid.
I have an advanced datagrid, but I want users to allow to copy some lines they want. when I use the property editable they are allowed to select the text they need, but they also are allowed to edit this. How can I prevent that?
I want users to be able to select any text in the datagrid, but they are not allowed to change the value of the grid. They should only be allowed to select and copy (ctrl + c).
I have need to restrict user input. TextInput should restrict all special characters and punctuation. Any other characters are allowed. In java there is a regex patter:
I have a possible bug for datagrid in cs4 (as3). The scenario involves having horizontal scrolling, good number of columns and editable columns.
The following codes basically layout that particular scenario.
The bug is the edibility of columns on the far right. If you click on them to try to edit them, another column on the left of it would become editable instead.
Here's a question for you. I have a dataGrid that I want to be able to edit only when the user clicks on a particular button. When this happens, I make the dataGrid editable and I make that particular column editable. After the user modifies the cell's content and hits ENTER, I want the edit cell to close and the dataGrid to once again become non editable. Here's the code in my Key.onKeyUp listeneif(Key.getCode() == Key.ESCAPE || Key.getCode() == Key.ENTER){ my_dg.getColumnAt(2).editable = false; my_dg.editable = false;}If the user hits ESC, the edit box closes correctly. If he hits the ENTER key, the edit box remains visible until he hits ENTER once more. Only then does it disappear
I am currently working on making my Flex application accessible. I have an mx DataGrid that I am using for showing complex data. Each row contains information about a person and one of the columns contains a button to "submit" that person's information. Currently if I tab to the DataGrid, it has focus on the whole thing, but I cannot tab to individual cells. For accessibility purposes, I need the user to be able to tab to each of these cells to read the information. Everywhere I've looked I've found that it seems the only way to focus on an individual cell is to set the editable property to true. However, I do not want to make the field editable, as that information should not be changed.
At the very least I would like to be able to tab to the cell that has the button ItemRendender for each person. I could set the rest of the information in the accessibilityName of that. Is there any way to accomplish this? Or am I going to have to find a more "creative" solution?
i have a problem using the itemRenderer functionality. When using an ArrayCollection the visible Data in the DataGrid using the itemRenderer will be rendered just fine. But if i start scrolling the entries are repeating in the cells using the renderer. The cells are not filled with date according to the id. What mistake i'm doing here.
I read a lot of the explainations like:

here is the code for the set data function (itemRenderer is extending HBox):
override public function set data(value:Object):void { _data = value; if(data!=null)
I am currently trying to disable the selectable / editable / or change the textInput to dynamic to get my desired result.I've got a custom datagrid with dropdowns and text input areas. However, if there is no data in my Model # column, I do not want to allow for any entry in the corresponding PurchasePrice cell.
col1 = new DataGridColumn("Model"); col1.headerText = "Model #"; c2.consumables_dg.addColumn(col1);
How do I provide values from the dataprovider (which is an array of objects) to these individual numeric steppers. dataField cannot be mentioned in the NumericStepper tag it seems.
I have an editable grid and would like to update values based on the edited cell and I am doing this in the itemEditEndHandler such that when they finish editing a cell I update other cells that are dependent on it. the only problem is in the itemEditEndHandler the new value has not registered yet. If I try and get the value of the cell i find that its still giving me the old value and not the new value that I have entered.

I have Flex 4 DataGrid, what I would like to do is when an cell has been edited, I would then like to walk through the values of that column and preform math on the values, e.g., I want to total up certain values.
1) How do I reference individual values of a specific column so that I may set them. 2) How do I then set those values or should I create a new column array and pop it in place of that column.
I have a mxml component with a datagrid listing project names and code versions. I have the selected projects from the datagrid binded to a public variable named "selectedProjects". But how to access this variable in another mxml component. I want the selected project's name in that component's text area. I even created an instance of the first component and using that called the selectedProjects variable. But I do not get the value updated in the text area.
This is the code for the first component where I get the selected projects name in a variable:
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'm using a custom component CheckBoxList DataGrid (http://blogs.adobe.com/aharui/2008/02/checkbox_selection_in_datagrid.html) and as dataProvider I have an ArrayCollection with items such this one:
name="item name" selected="true"
I would like the CheckBox list updated when the selected attribute is set to false or true in the data model.
How can i update multiple cells of the same row changing the value of a single cell of the same row ??
Example: id, height, weight, fat percentage, corporal mass. When i change one of the values in a row (except id of course) the corporal mass cell value must change using a formula like: (height/weight2)*fat percentage*100. Is this posible with Datagrid or AdvancedDatagrid in Flex ??
I tried using custom item renders and inserting actionscript code inside the datagrid with no good result.
