How do I add the data a user inputs into a DataGridView?

I have a DataGridView which has 1 column. I want the user to add as many rows they need. Then when they move onto the next tab the rows are saved. At the moment the user enters the data and can move to next tab and if they go back the data is still there. However when I try to save the data when they leave the tab, the row count for the DataGridView is 0. Therefore not entering the foreach statement where I try get the cell data from.

My code for when I try to get the data is-

C#

foreach (DataRow row in gv_mullionList.Rows)
{
  //never gets this far
  //would set cell value to an object
}

Why do I need to do to get the rows?

Where are you putting the code with the foreach ? (specifically which event I mean)

Add an event handler for the condition you wish to capture. This could be adding a row or ending the edit of a cell. In either case that is the point at which to check the content of any new cell in the grid.

You can add the user entered values into a datatable and persist the datatable in viewstate or session. Just bind gridview whenever needed.
