Hi, I am trying to change the font color or the row color on a datagrid component on Flash MX 2004, the data comes from an array.

I tried with a cell render putting the text on a text field and setting the color using html, I was able to chage the color, but now I can't order the columns when clicking the column header.

I would prefer to do it without cellRendering any way here is how I tried to do it:

The HtmlCellRender I am using is this:

import mx.core.UIComponent;
import mx.controls.TextArea;
import TextField.StyleSheet;

class HtmlCellRenderer extends UIComponent
{

      static public var CssUrl : String;
      public var style_sheet : StyleSheet = null;
      var htmlComponent : TextField;
      var listOwner : MovieClip;  
      var getCellIndex : Function;
      var getDataLabel : Function;      
      var previousLabel:String = null;

      function HtmlCellRenderer()
      {
            if (CssUrl != undefined && style_sheet == null) {
                  style_sheet = new TextField.StyleSheet();
                  style_sheet.load(CssUrl);      
              }
      }

      function createChildren(Void) : Void
      {
            if (htmlComponent == undefined)
            {
                  createLabel("htmlComponent", 1);
            }
            htmlComponent.html = true;
            htmlComponent.multiline = false;
            htmlComponent.wordWrap = false;
            htmlComponent.selectable = false;
            size();
      }

      function size(Void) : Void
      {
            var h = __height;
            var w = __width;
            htmlComponent.setSize(w-4, Math.max(h, listOwner.rowHeight-4));
            htmlComponent._x = 1;
            htmlComponent._y = 1;
      }

      function setValue(str:String, item:Object, sel:Boolean) : Void
      {
                        if (item == undefined) {
                  if (htmlComponent != undefined) {
                        htmlComponent.text = "";
                        htmlComponent._visible = false;
                        previousLabel = null;
                  }
                  return;
            }
            
            htmlComponent._visible = true;
            var columnIndex = this["columnIndex"];
                                var columnName = listOwner.getColumnAt(columnIndex).columnName;
            var htmlFunction : Function = listOwner.getColumnAt(columnIndex).htmlFunction;
            if (htmlFunction != undefined) {
                  var label = htmlFunction(item, columnName);
                  if (label != undefined) {
                        if (label != previousLabel) {
                              var oldStyleSheet = htmlComponent.styleSheet
                              if (oldStyleSheet != style_sheet && style_sheet != null) {
                                    htmlComponent.styleSheet = style_sheet;
                              }
                              htmlComponent.text = label;
                              previousLabel = label;
                        }
                  } else {
                        htmlComponent.text = "";                        
                  }
            }
      }

      function getPreferredHeight(Void) : Number
      {
            return 16;
      }

      function getPreferredWidth(Void) : Number
      {
            return 20;
      }
}



And then in the movie I have this function:

HtmlFunction = function (itemObj:Object, columnName:String) {
      if (itemObj == undefined ) {
            trace("A bug !!!");
            return;
      }
      var objData = itemObj.Cliente.datos;
      var objStyle = itemObj.Cliente.estile;
      var html:String;
      switch (columnName) {
            case "Cliente":
                  var objData = itemObj.Cliente.datos;
                  var objStyle = itemObj.Cliente.estilo;
                  break;
            case "Razon":
                  var objData = itemObj.Razon.datos;
                  var objStyle = itemObj.Razon.estilo;
                  break;
            case "RFC":
                  var objData = itemObj.RFC.datos;
                  var objStyle = itemObj.RFC.estilo;
                  break;
            case "Clase":
                  var objData = itemObj.Clase.datos;
                  var objStyle = itemObj.Clase.estilo;
                  break;
            case "Usuario":
                  var objData = itemObj.Usuario.datos;
                  var objStyle = itemObj.Usuario.estilo;
                  break;
      }
      html="<p class='" + objStyle +  "'>" + objData + "</p>"
      return html;
}

And this is the way I set up the columns:

var column = new DataGridColumn("Cliente");
column.headerText = "Cliente";
column.width = 50;
column.cellRenderer = "HtmlCellRenderer";
column["htmlFunction"] = HtmlFunction;
resultados.addColumn(column);

AllordenS,

I appologize for not giving an indepth answer however I think your problem will be easily fixed after reading through the following help guide supplied by Macromedia, Inc.

Customizing the DataGrid component (Flash Professional only)

You can transform a DataGrid component horizontally and vertically during authoring and runtime. While authoring, select the component on the Stage and use the Free Transform tool or any of the Modify > Transform commands. At runtime, use the setSize() method (see UIObject.setSize()). If there is no horizontal scroll bar, column widths adjust proportionally. If column (and therefore, cell) size adjustment occurs, then text in the cells may be clipped.

Using styles with the DataGrid component
You can set style properties to change the appearance of a DataGrid component. The DataGrid component inherits Halo styles from the List component. (For more information, see Using styles with the List component.) The DataGrid component also supports the following Halo styles:

Style
 Description
 
backgroundColor
 The background color can be set for the whole grid or for each column.
 
labelStyle
 The font style can be set for the whole grid or for each column.
 
headerStyle
 A CSS Style Declaration for the column header that can be applied to a grid or column.
 
vGridLines
 A Boolean value that indicates whether to show vertical grid lines (true) or not (false).
 
hGridLines
 A Boolean value that indicates whether to show horizontal grid lines (true) or not (false).
 
vGridLineColor
 The color of the vertical grid lines.
 
hGridLineColor
 The color of the horizontal grid lines.
 
headerColor
 The color of the column headers.
 

If the above table indicates that a style can be set for a column, you can use the following syntax to set the style:

grid.getColumnAt(3).setStyle("backgroundColor", 0xff00aa)

Using skins with the DataGrid component
The skins that the DataGrid component uses to represent its visual states are included in the subcomponents from which the data grid is composed (ScrollPane and RectBorder). For information about their skins, see Using skins with the ScrollPane component and Using skins with the List component.

The rollover and selection underlays, however, use the ActionScript Drawing API. To skin these portions of the data grid while authoring, modify the ActionScript code in the skin symbols in the Flash UI Components 2/Themes/MMDefault/datagrid/ skins states folder in the library of one of the themes FLA files.



If you need any help putting this into practice, let me know.

Cheers
