如何从asp.net gridview行中获取选定的行索引

Question

我有一个没有数据键的gridview。单击行编辑按钮时，将进入行编辑方法。我尝试了几种获取行索引的方法，但是没有运气。

   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();
   }

如何获取所选的行索引？

Answer 1

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。
