load data from CSV + headings

Great project! Keep up the good work ...

On loading data from a CSV, would be nice if 1st line
could be treated as the heading field, or having a way
to mark a set of entries as heading. Thx

OK, I add this to the requirements list

Better yet would be to load the data from an XML fragment & use the tags as the headers.

XML GET and POST asynchronous data requests should be available very soon. It would allow extracting tag names and using them as headers. I'm also thinking of supporting SOAP - if I can find a nice way of avoiding complex manipulation with the message format.

When do you expect to have XML support? It says Nov03 but with holidays coming up will you be able to keep that deadline?

I should have something working later this week - which is still November :-)

FYI - i was able to get closer to being able to use dynamic (unknown) data, without knowledge of columns... basically, I just make more than I will need, and hide the ones that look empty (based on the first column).

This is NOT bugproofed, nor even well thought out code - just me trying to make it work.

//    create ActiveWidgets data model - text-based table
    
var table = new Active.Text.Table;
    
//    provide data URL - plain text comma-separated file
    
table.setURL("myDataGenerator.csv");
    
//    start asyncronous data retrieval
    
table.request();
    
//    define column labels
    
var columns = ["A""B""C""D""E""F""G""H""I""J""K""L""M""N""O""P"];
table.getText=function (ij) {
    if (
this._data[i][j]==undefined || this._data[i][j]=="") {
        if (
i==0) {
            
// first row - no data = hidden row (or any other change)
            
return "<style>.active-column-"+j+" { display:none; }</style>";
        }
        return 
""
    } else { 
        return 
this._data[i][j]; 
    }
}
    
//    provide column labels
    
obj.setColumnProperty("texts"columns);
    
//    provide external model as a grid data source
    
obj.setDataModel(table);
    
//    write grid html to the page
    
document.write(obj);
 
It's still not hiding the column headings... would be nice if it did... if anyone figures this out, let me know : alan_aw@zeroasterisk.com | http://zeroasterisk.com
