I have a ToolStripContainer which contains two ToolStrips in it's TopToolStripPanel. It seems like if I open and close the form which contains the panels in the designer, they always move to a new location. Any ideas why that might be happening?

Also, I notice that each ToolStripPanel which is part of the ToolStripContainer has a little arrow on it in the designer. When I click on it, it switches directions, from pointing in towards the ContentPanel of the ToolStripPanel to pointing towards the nearest edge of the ToolStripPanel. What do the arrows mean?

Hi,

For your first problem, do you open the form containing the ToolStripContainer at design time or run time? I couldn't reproduce the problem either at design time or run time. Open the .design.cs file of the form and navigate to the InitializeCompoment method to see if the Location property of the two ToolStrip which are added to the top toolstrip panel has been set.

For your second question, the little arrow on each of the four toolstrip panel within the ToolStripContainer is a glyph which is used to expand or collapse the corresponding toolstrip panel at design time. When a ToolStripPanel is expanded, you can add controls into this ToolStripPanel.

Hope this helps.

Sincerely,
Linda Liu

The problem is during design time. I'm not sure why you marked your response as an answer since you couldn't reproduce my issue. As for the little arrows, they do not expand those controls.

Hi Bpeikes,

I thought I had answered your second question. As for the first problem, I made a suggestion which may solve the problem.

Have you checked the code in the InitializeComponent method of the form to see if the Location property of the two ToolStrip are set?

As fo the little arrows, if you click on it, the corresponding ToolStripPanel within the ToolStripContainer will open or hide.

Sincerely,
Linda Liu
