Datagrid headerRenderer checkbox to select checkboxes in the row

Filed under: Flex — Tags: , , , , — deepuverma @ 6:39 am

I had been trying out to implement the datagrid headerrenderer + itemrenderer to allow select all/deselect all checkboxes on the datagrid rows

I have picked various ideas from the examples given by Alex on datagrid itemrenderers and created a demo to show how to implement the checkbox select all with header renderer.

[You can preview the example to see what I am talking about and download the code here]

This was the first time I was there at a User Group Conference. initRIA was simply rocking. Live-Documents by InstaCol blew up our minds. There was lot to learn and see what people in the community are doing.

Thanks to the organizers and the sponsors for giving a rocking event.

Flex 1.5 to Flex 2 actionscript converter

Filed under: Flex — deepuverma @ 6:22 pm

I had been asked by my manager on how much time will it take to convert the intranet Flex 1.5 application to Flex2. Instead of doing the basic stuff for converting the app manually, I thought of writing a utility of replacing code.

The utility takes care of the following

I . Finds and replace
1. application namespace
2. Void with void
3. newline with \n in .as file
4. _root with Application.application
5. Application.alert with mx.controls.Alert

II. package the class

Following are the regular expressions I have used to replace the content (not sure if this is the best way to do the task)

file_content = Regex.Replace(file_content, "xmlns:mx=\"http://www.macromedia.com/2003/mxml\"", "xmlns:mx=\"http://www.adobe.com/2006/mxml\"");
file_content = Regex.Replace(file_content, "\bvoid\b", "void",RegexOptions.IgnoreCase);
if (fi.Extension == ".as")
{
file_content = Regex.Replace(file_content, "\bnewline\b", "\"\n\"", RegexOptions.IgnoreCase);
}
else
{
file_content = Regex.Replace(file_content, "newline", "#&13;", RegexOptions.IgnoreCase);
}
file_content = Regex.Replace(file_content, "\b_root[.]\b", "Application.application.", RegexOptions.IgnoreCase);
file_content = Regex.Replace(file_content, "\bApplication.alert\(", "mx.controls.Alert.show(", RegexOptions.IgnoreCase);
String packagename;
if (fi.Extension == ".as")
{
Match m = Regex.Match(file_content, @"(?<class>class)(?<packages>.*[.])(?<classname>.*)");
file_content = Regex.Replace(file_content, @"(?<class>class)(?<packages>.*[.])(?<classname>.*)", "${class} ${classname}");
packagename = m.Groups["packages"].Value;
file_content = "package " + packagename.Substring(0, packagename.Length - 1) + "{n" + file_content;
file_content = file_content + "n}n";
}

cfgrid cfajax enhance keyboard accessibility

Filed under: CFAJAX — deepuverma @ 2:06 am

cfgrid has the default selection mode as RowSelectionModel, if you want to give your user keyboard accessibility (so that the user can move around the data grid cells with key board arrow keys and edit content easily) perform the following changes in the \ColdFusion8\wwwroot\CFIDE\scripts\ajax \package\cfgrid.js file (I am not sure if the license agreement allows to change this file on your server)

 

  1. Search for new Ext.grid.RowSelectionModel and replace it with new Ext.grid.CellSelectionModel();
  2. Search for this.grid.getSelectionModel().selectFirstRow(); and comment it out
    //this.grid.getSelectionModel().selectFirstRow();
  3. Search for this.grid.getSelectionModel().selectRow and comment the line

Filed under: ColdFusion — deepuverma @ 6:26 am

I am tired of writing cfdump or cflog statements to debug my CF code. CF 8 has come to rescue with the IDE debugger. I have installed the plugin on FB3 and love it.

This article on devnet will help you to setup the debugger for Eclipse.
