I tried that, but had problems figuring out how to put the name in. I may not have explained very well. Lets say I have the following datagrid with an id=books: +-------------+----------+-------+------------+ | Condition | Course | Price | Bookname | +-------------+----------+-------+------------+ | In Plastic | EMB 101 | 100 | Embryology | | Well-read | EMB 102 | 75 | Embryology | | In Plastic | Anat 101 | 100 | Anatomy | | In Plastic | Anat 101 | 100 | Anatomy | | Highlighted | Anat 102 | 25 | Anatomy | | Well-read | Surg 101 | OBO | Surgery | +-------------+----------+-------+------------+ The user can click in any cell in any row or column. If the user clicks in row2, column3, I can use rowIndex and columnIndex to get 2 and 3. I could get the data by doing books[2].Bookname, but how do I know that Bookname is the heading for column 3? I could do a lookup that says if columnIndex==3, then fieldname=Bookname, but how do I use a string variable in the call? I know I can do books[rowIndex].Bookname to get the data, but how do I use a variable for the column name? Or do I just know that because Im hardcoding in the field names for the columns in the DataGridColumn? If I just let the DataGrid component build the columns, then the columns are dependent on the order of the fields in the underlying database format and if I ever have to change that format, then Id have to update all of this. Id like something a little more portable. Did I explain that ok? Thanks for your help! It really is appreciated!

Your datagridcolumns use .datafield to pull the field. So it would be something like acMyStuff[1].name _____ From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Ramsey, Robert L Sent: Monday, October 15, 2007 10:42 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] value of clicked/focused cell in a datagrid Ok, I am definitely being a real idiot here. All I want to do is find out the value of cell that a user has clicked on, tabbed into, or entered into. I can get the row number and column number, but I cant find the syntax to get the data out of the arraycollection. For other languages, Id just do something like val = acMyStuff[1][4] to get the data from the multidimensional array. Any ideas? Thanks. Bob
