“除非指定了DeleteCommand，否则数据源'SqlDataSource1'不支持删除”但仍然会发生删除

Question

我正在为asp.net开发一个项目，并添加了我删除记录的代码。但是，当我运行它时，我收到错误

  

数据源“SqlDataSource1”不支持删除，除非   指定了DeleteCommand。

广泛的谷歌搜索没有得到足够的答案。此外，当我检查我的SQL表时，删除命令已成功删除该条目，但仍然出现此错误。任何帮助将不胜感激。

Protected Sub GridView1_RowDeleting(sender As Object, e As GridViewDeleteEventArgs) Handles GridView1.RowDeleting
    Dim thisID As String
    Dim strSQL As String
    ' Get the id - Cell(0) is the first column in the grid
    ' If you have the delete or edit links on the left this column will change!
    thisID = GridView1.Rows(e.RowIndex).Cells(5).Text
    ' Delete the specific record
    ' Use hard-coded values first to check your work
    ' strSQL = "DELETE FROM userTable WHERE id = 25"
    strSQL = "DELETE FROM " & TABLE_NAME & " WHERE Name = '" & thisID & "'"
    runNonSelect(strSQL)
    RefreshGrid()
End Sub
