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.

View 1 RepliesHow 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.

View 4 RepliesI 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?

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?

View 1 RepliesI am working on a problem since a week soon, but I still couldn't make it work as expected. I have a DataGrid which has HBox with a CheckBox an a Label as itemRenderer (see Code below). When I tap in to the Cell the standard itemEditor pops up and lets you enter the content of the label. Thats the standard behavior. I works fine except for 2 problems:
If I enter to much text, the horizontal srollbar pops up, and the cell is filled with that scrollbar. As you see I tried to set the horizontalScrollPolicy to off, but that doesnt work at all... I tried to do that for all the different elements, but the failure is still existent. When I have filled more than one row, there is an other mistake happening. If I tap on a row, the datagrid selects the one below that row. That's only if one line is already selected. If I tap outside the datagrid and then, tap at any row the itemEditor of the right row will show up... Is there anything now wright in the setup of my set data method?

Both have single columns. Selecting one item from Divsions datagrid should display members of that Division in the Members datagrid. But following code has some problem and Members of a particular division do not show up when respective Divsion is clicked.
Following are some snippets of the related code. Hope someone can spot an error in it.

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.

For poor performance reasons, the DataGrid will cache checkboxes and reuse them for different rows. If you have 50 rows, it won't create 50 checkboxes. It will create as many checkboxes at are visible, plus a few more for padding, and then reuse them as you scroll. This is why you need to explicitly manage their state. How can improve it ? How can fixed checkbox value ? i used checkbox like below But checkbox doesnot remembering the values

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?
View 1 RepliesI am attempting to style the headers in a flex datagrid and I keep getting the warning:
Type DataGrid in CSS selector 'DataGrid' must be qualified with a namespace
What does this mean? I have gone through a bunch of tutorials and none of them have worked. It seems like changing a the colors in a datagrid should be relatively simple.
Here is a code sample:

.headerCustomStyle

in Flex I have something like that: [code]and dg is ALWAYS pointing at DataGrid (even if dg1 has name DataGrid_test and dg2 = DataGrid_test2) and finally action is made on my first DataGrid (DataGrid_test).[code]and search still points at ColorColumn :/ My problem is really easy- I just want to pass to search different dataGrid on each state.But still I don't understand why it doesn't work. My search function uses algorhitm Boyer-Moor for searching through dataGrid.dataProvider for some text. If it find something then it is pushed into new array and after passing whole dataProvider I colorize rows with searched word.

View 5 RepliesI have a TabNavigator, and each tab is a Module. One of the modules is labelled Units and the full code of the module is posted in this post. There are several problems:
1) Forms are not populated with data from the datagrid selection.
2) Selecting a row and clicking delete gives the very-common error: TypeError: Error #1009: Cannot access a property or method of a null object reference.
A trace on the valueObject unit within the selectionChangeHandler function gives NULL. Why? Note: In other modules (other tabs of the TabNavigator), I have DropDownLists populated with units. This means that the valueObject Unit is defined in the other modules. However, valueObjects should be private to modules, and not shared.

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'm using Flex 4 and I need to render the data that resembles HTML Table with row span in a Flex component.My inclination was to use a DataGrid but I believe that rowSpan is not supported for that component. I looked at the AdvancedDataGrid but the user does not want to have a tree-structure in any of the columns. Looking to see if there are any hints/tips for modifying the DataGrid or AdvancedDataGrid to produce an "HTML Table with rowspan" look.

I have several datagrids with changing columns. For the text fields the datagrid's sort function neems to be making a case sensitive compare. eg. the following list sorted would look like this apples strawberries Autos Autos should be with apples but since the capital A is counted differently all capital letters come after. I've found a lot of information on setting a CASEINSENSITIVE flag, but I can't figure out where to do this. The best solution would be one where I can override the default behavior to be case insensitive for all my datagrids and all my compare functions.
View 3 RepliesI am in a situation where user gets the cars data from the database based on the selection and displays it in datagrid like below ( for example)

and there will be a link next to datagrid to get Pie chart based on the data displays in the data grid . The pie graph should display grouping by company and the count . I mean for the above example that should give with two pie items , one for GM showing the number of vehicles ( in this case 3 ) and Honda showing the number of vehicles ( in this case 1 ).
I thought of getting it from the database by querying and grouping it .But here the problem is after getting the data above in the datagrid user can able to filter at client end ( By year or model ) and can say get graph . This time that should only display the graph for the data visible in Datagrid .Grouping on database for every operation is becoming expensive. Since we have already data available at client end , is there any way to group it at client ..?
