[Help] Ext.grid.ColumnModel Multiple dataIndex Possible?

Posted in xn--kfs74mzzid01b.com edit by mike on January 7th, 2009

Hi again guys, another - most likely - simple question from me again!

I'm starting to move along with ExtJS and have no got to the point where im looking at building a simple test application to demonstrate the powers of ExtJS to the rest of my colleagues at work + management.

Im wanting to know if its possible to use the Ext.grid.ColumnModel.dataIndex with multiple sources form a data store.

Lets say i have the basic fields for a name in a JSON output (Title, Forename, Surename) and i would like to merge all three fields into one column.

Would the ideal way around this to merge these fields before i output the JSON or is it possible to pass multiple variables to the Ext.grid.ColumnModel.dataIndex?

Cheers

You'll be wanting to look at the renderer option in the columnModel.

I just realised it isn't documented very well:

function someRender(value, cell, record)
{
return '';
}

Thanks for the heads up evant, i have already been using that for some basic formating - i'll read into it a little bit more but im guessing that it will have full access to the data store values?

It's taken me a while but im starting to get to grips with this now :) tis good for a XHTML/CSS guy that has said for years that Flash and JS are the devil of the web :D
