what, no one is replying for this ???

atleast, is there are any tutorials in this..........

Here is something that might help with #3. (It's probably more than you need,
but it's what I have handy.)

On a stage with a datagrid (dg), a dataset (ds) and 6 textinputs (tb0 - tb5)...

The data provider for dg is bound to the data provider for ds.

Each instance of the text input (will be) bound to a different item in the
dataset.
If you change a (bound) cell in the datagrid, the corresponding text input
changes, and vice versa.

The following actionscript (dynamically) binds the textinputs to ds.

//---------------

import mx.data.binding.Binding;
import mx.data.binding.EndPoint;
import mx.data.components.DataSet;
//
var boundElementName = "name"; // name of the ds element to bind to the text
boxes
var loop = 6; // number of items to put in the data grid (the text boxes are
static) - what? I was lazy
for (var ndx = 0; ndx < loop; ndx++)
{
    //
    // set the end points for the binding that moves data from the dataset to the
text boxes
    var src = new EndPoint ();
    var dest = new EndPoint ();
    src.component = ds;
    src.property = "items";
    src.event = "modelChanged";
    src.location = {path:["[n]", boundElementName], indices:[{constant:ndx}]};
    dest.component = _root["tb" + ndx];
    dest.property = "text";
    new Binding (src, dest);
    //
    //set the end points for the binding that moves the data from the text boxes
to the dataset
    //  (note the different event)
    src = new EndPoint ();
    dest = new EndPoint ();
    src.component = _root["tb" + ndx];
    src.property = "text";
    src.event = "change";
    dest.location = {path:["[n]", boundElementName], indices:[{constant:ndx}]};
    dest.component = ds;
    dest.property = "items";
    new Binding (src, dest);
}
//
// fill the data set with junk
for (var ndx = 0; ndx < loop; ndx++)
{
    var to = new Object ();
    to.name = "name" + ndx;
    to.stuff = "timer: " + getTimer ();
    to.number = ndx;
    ds.addItem (to);
}
//
// this code is just to make the datagrid sync with the changes to the text
boxes.
//   - the data set is already changing, but the changes will not show in the
datagrid without a little "help"
//
tbChangeObject = new Object ();
tbChangeObject.focusOut = function (eventObject)
{
    ds.refreshDestinations ();
};
for (var ndx = 0; ndx < loop; ndx++)
{
    _root["tb" + ndx].addEventListener ("focusOut", tbChangeObject);
}

//---------------

Hope this helps.

Hi GeoffEly,
that's great....amazing.......it works....

but a small doubt....
whether is it possible to give dynamic value in the constant property

src.location = {path:["[n]", boundElementName], indices:[{constant:ndx}]};

here you had specified ndx, instead of ndx, I want to specify the
selectedIndex property of my combo box.....

is this possible..????

Please help
