如何从asp.net gridview行获取选定的行索引

Question

I have a gridview with no datakeys. When I click the row edit button, I'm taken to the rowediting method. I've tried several ways to get the row index, but no luck.

   protected void gvwCustomerLocation_RowEditing(object sender, GridViewEditEventArgs e)
   {
        var index1 = e.NewEditIndex;  //gives me an incorrect index number

        //The SelectedIndex always equals -1
        for (int i = 0; i < gvwCustomerLocation.Rows.Count; i++)
        {
            if (gvwCustomerLocation.SelectedIndex == 1)
            {

            }
        }

        int index = gvwCustomerLocation.EditIndex;  //The EditIndex = -1

        GridViewRow row = gvwCustomerLocation.SelectedRow;  //The SelectedRow = null
        var test = row.RowIndex.ToString();
   }

How can I get the selected row index?

我最终放弃了从gridview获取行索引的决定，决定在sql服务器结果集中创建一个主键，以用作前端的键。
