I have added a panel control at the design time and I want to add some buttons in the panel at the runtime, the code for adding the buttons in working perfectly, but the problem is with the Panel control, when the Buttons are added at the run time, the Panel hides the buttons behind itself, can anyone suggest the solution, I am pasting the code from designer as well the code that I have written. Please correct my mistake.

Code from Form3.Designer.cs:

namespace rough2

{

partial class Form3

{

/// <summary>

/// Required designer variable.

/// </summary>

private System.ComponentModel.IContainer components = null;

/// <summary>

/// Clean up any resources being used.

/// </summary>

/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>

protected override void Dispose(bool disposing)

{

if (disposing && (components != null))

{

components.Dispose();

}

base.Dispose(disposing);

}

I can't go through all your code but here are a few things you may wanna know.
>> if two controls are placed on the form in the same location which I assume it is in your case, the container control will be preferred. your best chance in this instance is to place those buttons inside the panel itself not on the same location or underneath.
