this.ImageButtonBack.Attributes["OnClick"] = "g_PDisConnectKP();return g_CloseWindow()";这个方法单击ImageButtonBack按钮时不会关闭窗体。
修改为：this.ImageButtonBack.Attributes["OnClick"] = "g_PDisConnectKP()";
this.ImageButtonBack.Attributes["OnClick"] = "return g_CloseWindow()";时单击ImageButtonBack按钮就可以关闭窗体。
this.ImageButtonBack.Attributes["OnClick"] = "g_PDisConnectKP();return g_CloseWindow()";这句话错在哪里？要怎么修改，谢谢了。
