Get value from GridView

I am trying to get the value from a GridView and save it as a Session variable.

I know the column name and there is only ever one value in the GridView. What is the best way to select it and save as the Session variable?

The column name is CustomerID and the value is always a int.

You can set a DataKey for GridView as CustomerID and select by:

int ID = Convert.ToInt32(GridView1.DataKeys[indx].Value);

indx is Row Index in GridView..

This is not a proper way to do this, you better hardcode the cellindex but anyways a little longer version of Damith's answer

if (GridView1.Rows.Count > 0)
{
    int indexofcolumn = 0;
    foreach (DataControlField column in GridView1.Columns)
    {
        if (column.HeaderText == "CustomerID") break;
        indexofcolumn++;
    }
    Session["CustomerID"] = GridView1.Rows[0].Cells[indexofcolumn].Text;
}

if there is one column and one row in the GridView you can try below.

Session["MySessionValue"]=  GridView1.Rows[0].Cells[0].Text;

but exception can be thrown when you access by index if there is no records in the GridView. So better to check GridView1.Rows.Count First and get the value
