is that a answer or another question ?, put your question in comment rather then in answer section.
I assume you want an event handler method to be executed in the CodeBehind when user selects a value in the DropDownList inside the GridView. To do this, I have the following suggestions:

After the line

DropDownList drptype1;
drptype1 = (DropDownList)(e.Row.FindControl("drpitem"));


Add the following line of code to add a SelectedIndexChanged event handler to the DropDownList:

SQL
drptype1.SelectedIndexChanged += new EventHandler(DropDownList_SelectedIndexChanged);


And, define the EventHandler DropDownList_SelectedIndexChanged in the CodeBehind as follows:

C#
void DropDownList_SelectedIndexChanged(object sender, EventArgs e)
{
        DropDownList ddl = sender as DropDownList;
        if (ddl != null)
        {
            string selectedValue = ddl.SelectedItem.Value;
            string selectedText = ddl.SelectedItem.Text;
        }
}
