问题现象
当多个ToolStrip使用ToolStripContainer布局时,可以让用户自己拖动工具栏,所以在程序关闭时必须保存用户拖动工具栏的位置,但是在再次打开程序后,还原回来的工具栏位置会有问题,虽然设置的与原来一致,但是起不了效果,每次位置都不确定
问题原因
产生问题的原因是在设置ToolStrip.Location时,没有没有挂起容器的布局,导致位置不确定
解决方法
在设置Location前要添加
container.SuspendLayout();
container.TopToolStripPanel.SuspendLayout();
container.LeftToolStripPanel.SuspendLayout();
container.RightToolStripPanel.SuspendLayout();
container.BottomToolStripPanel.SuspendLayout();
完成之后添加
container.TopToolStripPanel.ResumeLayout();
container.LeftToolStripPanel.ResumeLayout();
container.RightToolStripPanel.ResumeLayout();
container.BottomToolStripPanel.ResumeLayout();
container.ResumeLayout();
