RE: innertext, javascript, datagrid, database update

Hell Lyners,

I missed picking on something in your response. You said that there were no
controls in the cell! Well, that explains it.

You need to have controls in the cell. If you are copying the data to a
cell that is databound to the grid, e.g. <asp:BoundColumn>, then you will
certainly not get its changed value upon postback because it is only
represented by a regular HTML <TD> tag that does not carry a value upon
posting back the form.

What you need to do is to use the <asp:TemplateColumn> as I did in the demo
I gave you its link to create an <Input> control on the form that can carry
the value back upon posting the form.
