handle datagrid' s changed values,pls check

[hakanaktan]

Hi, I have a datagrid that a few columns are bounding after datagrid is created. I have to update changes that made on datagrid.So i create an "Edit" Column. Now i created virtual textBoxes for each edited cell, when user press edit, they get the first value of Editing Items from dataGrid. Now, how can i handle the changed value on dataGrid cells. My virtual textBoxes are created on ItemCreate event of dataGrid. Is there a way to get the last value of cells until user press update button.. code or idea would be so helpful. Thanx in advance.. --junior coder--
