keep button position on panel resize

问题

I've been messing around with something that should be simple.

I've moved jobs and trying to get some of the basic tools I have used before, but of course I don't have the old source to look at.

We had extended panel to have some standard properties and functions (save, close, save and close).

But I can't get the buttons to be positioned correctly on a resize. I put this ExtPanel on a form but the buttons keep disappearing as I resize, or don't move as expected (frozen on bottom right).

The class

public partial class ExtPanel: UserControl
   {
   private System.Windows.Forms.Button btnSaveandClose;
   private System.Windows.Forms.Button btnCancel;
   private System.Windows.Forms.Button btnSave;

   public ExtPanel ()
      {
      InitializeComponent ();
      }

// misc things this class does...


}

public partial class ExtPanel
    {
    private void InitializeComponent ()
       {
        this.btnSaveandClose = new System.Windows.Forms.Button();
        this.btnCancel = new System.Windows.Forms.Button();
        this.btnSave = new System.Windows.Forms.Button();
        this.panel1 = new System.Windows.Forms.Panel();
        this.panel1.SuspendLayout();
        this.SuspendLayout();
        // 
        // btnSaveandClose
        // 
        this.btnSaveandClose.Location = new System.Drawing.Point(899, 689);
        this.btnSaveandClose.Name = "btnSaveandClose";
        this.btnSaveandClose.Size = new System.Drawing.Size(100, 30);
        this.btnSaveandClose.TabIndex = 0;
        this.btnSaveandClose.Text = "Save and Close";
        this.btnSaveandClose.UseVisualStyleBackColor = true;
        this.btnSaveandClose.Click += new System.EventHandler(this.Click_SaveandClose);
        this.btnSaveandClose.Anchor = ((System.Windows.Forms.AnchorStyles) ((System.Windows.Forms.AnchorStyles.Bottom | System.Windows.Forms.AnchorStyles.Right)));

        // 
        // btnCancel
        // 
        this.btnCancel.Location = new System.Drawing.Point(687, 689);
        this.btnCancel.Name = "btnCancel";
        this.btnCancel.Size = new System.Drawing.Size(100, 30);
        this.btnCancel.TabIndex = 1;
        this.btnCancel.Text = "Cancel";
        this.btnCancel.UseVisualStyleBackColor = true;
        this.btnCancel.Click += new System.EventHandler(this.Click_Close);
        this.btnCancel.Anchor = ((System.Windows.Forms.AnchorStyles) ((System.Windows.Forms.AnchorStyles.Bottom | System.Windows.Forms.AnchorStyles.Right)));

        // 
        // btnSave
        // 
        this.btnSave.Location = new System.Drawing.Point(793, 689);
        this.btnSave.Name = "btnSave";
        this.btnSave.Size = new System.Drawing.Size(100, 30);
        this.btnSave.TabIndex = 2;
        this.btnSave.Text = "Save";
        this.btnSave.UseVisualStyleBackColor = true;
        this.btnSave.Click += new System.EventHandler(this.Click_Save);
        this.btnSave.Anchor = ((System.Windows.Forms.AnchorStyles) ((System.Windows.Forms.AnchorStyles.Bottom | System.Windows.Forms.AnchorStyles.Right)));

        // 
        // panel1
        // 
        this.panel1.AutoScroll = true;
        this.panel1.Controls.Add(this.btnSave);
        this.panel1.Controls.Add(this.btnCancel);
        this.panel1.Controls.Add(this.btnSaveandClose);
        this.panel1.Location = new System.Drawing.Point(0, 0);
        this.panel1.Name = "panel1";
        this.panel1.Size = new System.Drawing.Size(1008, 730);
        this.panel1.TabIndex = 0;
        // 
        // ExtPanel
        // 
        this.Controls.Add(this.panel1);
        this.Name = "ExtPanel";
        this.Size = this.panel1.Size;
        this.Click += new System.EventHandler(this.click_this);
        this.panel1.ResumeLayout(false);
        this.ResumeLayout(false);

        }

回答1:

Have you tried anchoring the button?

...I missed the anchoring code.

If you have a button in the lower right-hand corner that you want to stay in the lower right-hand corner when resizing the form, set it's anchor properties to Bottom, Right.

Update:
I loaded your code. You have a panel inside of ExtPanel. If you dock (Fill) that panel then you should be working fine by resizing ExtPanel.
