• Bad alignment of the column header separator and separator columns in mx:DataGrid.

  Hi all

  I use a mx:DataGrid control in my project of extension for InDesign CS5/CS55.5/CS6. I personalized the style attributes of the DataGrid control to change its appearance as shown in the following image.

  

  Question: As we see in the picture that after changing this style attribute separator column header is not aligned with separator of columns of the DataGrid body (more clearly shown in the zoomed image).

  

  I also found that if I remove the "headerColors" property then it seems (maybe because of camouflage of the dividing line white with the default color of the header, as shown in the image below).

  

  Any suggestion/solution to correct this lack of alignment.

  Notice that I must use this dark color appearance. I used FlashBuilder4.6, ExtensionBuilder2.1, ExtensionBuilder 3.4 SDK on Mac OS X 10.7.5.

  Here is the source code,

  DataGridExtension.mxml

  OK, the header separator is 2 pixels wide and that's why he is not in line with the separation of body that is only 1 pixel wide.

  Thank you. I solved the problem by adding a 'programming skin' based on 'mx.skins.halo.DataGridHeaderSeparator' that I defined for 'headerSeparatorSkin' mx:DataGrid property.

  I also tried adding a 'graph skin' by using a PNG image with a width of line 1 file x 22 pixels. This fixed the misalignment, but another problem because of which the last separator becomes 2 pixel wide while all others were 1 pixel wide.

  Here I post my code snippets for others,

  1. Add a new MyDataGridHeaderSeparator.mxml file for programmatic skin as follows (for example in the View.skin package).

  MyDataGridHeaderSeparator.mxml

  http://www.Adobe.com/2006/mxml '. xmlns:haloSkins = "" MX.skins.Halo. * ">" /** * Replaced it draw the line splitter in the DataGrid header columns. Since the default * implementation was originally 2 numbers when headerColors style in the DataGrid property changes * to match with the theme of dark color of the overall expansion, * 1. Misalignment of the separator in the header with the separation of body. * 2. Draw lines of separation of 2 pixels with the first in color light gray and others in dark grey. **/ override protected function updateDisplayList(unscaledWidth:Number,_unscaledHeight:Number):void {} The line width value 1 pixel to draw lines 1 pixel wide divider. graphics.lineStyle (1, 0 x 000000); Go from x = 0 to x = 1 to solve the problem of misalignment. graphics.moveTo (1, 0); Draw the line of separation of (1,0) (1, unscaledHeight). graphics.lineTo (1, unscaledHeight); } ]]>

  And then simply set the property 'headerSeparatorSkin' of mx:DataGrid to this skin, for example inline definition property as below,

• Cannot set the DataGrid column width

  I am very frustrated with the DataGrid control and I don't understand why it won't work. I followed the tutorial "Build year Application In An Hour" by Adobe and finally managed to extract data from a database in a DataGrid control, the data very well, but all the columns are the same width and will not change when creating. Of course I can drag the column widths when the DataGrid control has made, but you shouldn't do that. The columns are not enough even wide to fit in the title of each column. The tutorial mentioned resizing of columns, but does not specify how. I've manually entered in the < S:GridColumn > tags and entered like width = "800" see no change. I changed the width of the data grid itself, I even tried setting the width to 100%. I also went in the "Configure columns" dialog, and then in advanced and set a minWidth, but it still doesn't work, I even disabled 'resize' and still nothing. I also tried different combinations of the aforementioned attempts.

  How can it be difficult to set the width of a column?

  I should also mention that I use Adobe Flex Builder 4.5 for PHP.

  Well, I solved the problem and I'm very embarrassed to say that it is my browser cache. It was not show my saved new, which is a bit worrying plans sometimes that I need to change the small values and run my application every 10 seconds to see the update.

• Help with the creation of the Datagrid column

  I am trying to get a better understanding of the way the Spark DataGrid works so that I can create and version extended for one of my projects. One of the things that really left me speechless is how the datagrid sets up the columns based on the dataprovider when no explicit column is defined. I was able to debug through the initialization of the datagrid to the point where the setter for dataprovider is called. At this point, my debug trace goes "down the rabbit hole" so to speak and when she returns, the columns are initialized but I can't figure out how. Could someone tell me please to the class or function that is actually responsible for creating the columns of the dataprovider if they are not defined explicitly?

  So, as you have discovered, the Grid method / generateColumns (private) is called if the list of columns is always set to null when the commitPropertes().   Subsequently becomes the columns property, as a consequence of the liaison, should update the list of columns as expected.

  Could create an example that illustrates the problem you meet?   I'd be happy to look at it.

• Presentation of the bulletin, by aligning the columns, paragraph breaks, and lines of text

  Hello

  I've never drawn a newsletter before.

  It's annoying me because I try to be as meticulous as possible with my alignment, but I noticed there are all things that don't align.

  I have a paragraph style, with a space before and after. I have three columns. When I look at a line of text across all columns of three, they are not aligned. May they line up if I had all the text directly and no image wraps, but the envelopes of the image and the beginning of a new paragraph in column 2, throws the alignment in column 3.

  What is the best way to align things with the least possible effort?

  Are there tutorials on good bulletin of the layout-design? Presentation of the grid?

  Thank you

• Change the first column seen in the datagrid by code?

  Hello

  Is anyway to change the first column in a DataGrid using action script? I mean, for example, think I have 10 columns, only 3 are seen (0,1,2). I just want to have a button to change the first column view. Thus, for example, if I press it, 1.2, and third column will be those that is displayed in the datagrid control. I need to emulate the same thing that the scroll bar when you drag in a datagrid, but instead of letting the scroll bar does that automatically, I want to "scroll" datagrid manually.

  Moreover, is anyway through datagrid children and hide the scrollbar manually?

  Thanks in advance,

  Aron.

• Column of the datagrid to access from another column

  Hello

  Basically, I have 2 columns in a DataGrid, both with the checkbox itemRenderers.

  When I check the first box, I want the second either activated = false.  I'm stuck.

  Normally, you need work on the data provider, because the converters element are recycled, and you get strange results if you do not work on the DP.

• How can we change an image programmatically in the DataGrid cell

  I have a DataGrid that contains a status icon. I was able to get the initial to display in the DataGrid control status icon. But I'm unable to update the computer. Basically, I need to update the image of a selected line with a "assets/processing.png", ' assets/success.png' or ' assets/failure.png' image. I can't seem to be able to find a way to access the image in the cell need to update/replace it. I tried to give him a property from my collection ArrayCollection data provider, but it does not work. I also tried some how to get a reference to the original image, so it can be replaced, but can not understand how to do such. Here is the code for my DataGrid. I'll be very grateful for any help in this. (I'm relatively new on Flex/ActionScript, but a developer experienced otherwise).

  The image must be a property of the arrayCollection collection.  You can either save the image url as a property of type string, or if you must nest, then you can create an actionscript for each image object in a script (private var image1:Image = Image(); image1.source=@embed...)

  Then, in the code that processes the event that causes the image must change, replace the image property of the collection arrayCollection member (s) concerned. Then, at the end of the code for the event, trigger the DataGrid to update using the method myDataGrid.invalidateList ();

• How to dynamically add a column to the DataGrid

• Problem of masking and the columns in a datagrid

  I noticed that the order in which the values are displayed gets reversed when I hide or show the column in the datagrid control. The robot to hide is triggered when the in button header that is rendered using headerRenderer.The see the feature is triggered when the value in the drop-down list with the name of the appropriate column is selected. If there is no solution to this help me. I tried various possilibilities, but none worked. I develop applications on Flex Builder 3.
  
  Thank you and best regards,

  Hello

  I thought that this issue was raised in reason to use itemRenderer for individual DatagridColumns. This has been fixed as soon as I use itemRenderer for the entire Datagrid rather than the individual columns.
