Hi there,

This must be a common question but I can't find the answer.

I have a simple windows forms project. I create a form with say an OK and
Cancel button anchored to the bottom of the window. I compile the project.
Next I create a new form inherited from the previous. I add a label to it and
compile the code. Everything is ok. If I change the size of the derived form
(make it smaller) and then recompile I can nolonger see the buttons that were
on the base form.

Looking at the auto generated code in the derived class it seems to have
place a SuspendLayout and ResumeLayout around everything, including the call
the set the ClientSize of the form, hence the base classes buttons are not be
repositioned after the new size.

The code in the derived class is:

this.linkLabel1 = new System.Windows.Forms.LinkLabel();
this.SuspendLayout();
//
// linkLabel1
//
this.linkLabel1.Location = new System.Drawing.Point(256, 8);
this.linkLabel1.Name = "linkLabel1";
this.linkLabel1.TabIndex = 3;
this.linkLabel1.TabStop = true;
this.linkLabel1.Text = "linkLabel1";
//
// Form3
//
this.AutoScaleBaseSize = new System.Drawing.Size(5, 13);
this.ClientSize = new System.Drawing.Size(384, 118);
this.Controls.Add(this.linkLabel1);
this.Name = "Form3";
this.Controls.SetChildIndex(this.linkLabel1, 0);
this.ResumeLayout(false);

If I manualyy move the this.ClientSize = line to after the ResumeLayout
everything works ok.

Is this a feature, bug or my mistake. Does anyone know if there is a way
round it?

Thanks for your help.

BTW, I'm using v1.1 of the framework on WinXP.

I believe this is a bug on anchoring. I've experienced it and thankful to
Weigelt's article at

Thanks Joey,

that blog was excellant and fixed my problems.

In case you don't know, the problem with using Anchor in base forms seems to
be fixed in VS 2005 (Beta1 anyway ;-) ).
