still when form texh chnage event occurs it automatically calls the Dg_TextChanged event and I dont want that..

推荐答案

您的TextChanged处理程序也已设置为处理表单的textchanged事件，请查看此处

私有Sub Dg_TextChanged(ByVal发送者作为对象，ByVal e作为System.EventArgs) Handles Me.TextChanged.

如果要以编程方式添加和删除处理程序，则应删除它.

希望对您有帮助

Your TextChanged handler is also set to handle your forms textchanged event, look here

Private Sub Dg_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.TextChanged.

you should remove that if you want to programmatically add and remove the handler.

Hope this helps
