Datatable updating without using datarow loop

Datatable updating without using datarow loop

Is it possible to do the following:
I have the following datatable
=================================
ID || Width || Value ||
=================================
size-1 || 50 || ||
name-1 || 100 || ||
zip-1 || 50 || ||
size-2 || 50 || ||
name-2 || 100 || ||
zip-2 || 50 || ||
=================================
I want to be able to loop through the datatable and update the value
column, with the textcontrolbox.text value
Session[sectionName] = test;
DataTable dt = (DataTable)Session[sectionName];
var strIDS = from p in dt.AsEnumerable()
select new
{
ID = p.Field<string>("ID")
};
foreach (var strID in strIDS)
{
TextBox tempBox = DynamicControlsHolder1.FindControl(strID.ID)
as TextBox;
string val = tempBox.Text;
// This is where i want to be able to update the value column,
but i can't figure out how to
// Can someone please help
}
