在Windows窗体中，在窗体上添加此控件后，控件的应用程序位置已更改

Question

I am developing a Windows Forms application using Visual Studio 2010 and C#. I have created one user control to show a detail screen. When I added this user control on another form or user control in panel container then controls positions are changed. I used the doc property, but still see this issue.

PanelCancelledConainer.Controls.Clear();
InquiryDetailsCls.InquiryID = Convert.ToInt32(GridInquiry.SelectedRows[0].Cells[0].Value.ToString());
CtrlInqDetails inqDetails = new CtrlInqDetails(InquiryDetailsCls.InquiryID, 1);
inqDetails.Dock = DockStyle.Fill;
PanelCancelledConainer.Controls.Add(inqDetails);

What can I do so that user controls look as they do in design mode?

try to set index position of your usercontrol on the container that is:

PanelCancelledConainer.Controls.SetChildIndex(inqDetails, 0); 

you will be sure that it was the first child.
