Navigating through different forms in C#

I recently started working on an application with windows forms using C#. To navigate through the different forms I am using:
Form Form_name = new Form ();
Form_name .TopLevel = false;
panel1.Controls.Clear();
panel1.Controls.Add(Form_name);
Form_name.Show();
The current setup is that I have the main menu form where you then navigate to a upload photo form. But after uploading an image in the upload photo I want to show the next form. But because we now are working in another form we cant use:
panel1.Controls.Clear();
panel1.Controls.Add(Form_name);
Because panel1 is referenced in the first form. I tried to create a public class to clear it but had no success.
My questions come down to:
Is there a better method to navigate through different forms/windows?
Can we create a public function to clear the panel in the first form?
MainMenu.cs
private void mainMenu1_Click(object sender, EventArgs e)
{
ME_Upload ME_UploadConstruct = new ME_Upload();
ME_UploadConstruct.TopLevel = false;
panel1.Controls.Clear();
panel1.Controls.Add(ME_UploadConstruct);
ME_UploadConstruct.Show();
}
private void mainMenu2_Click(object sender, EventArgs e)
{
IndividualEditor individualEditor = new IndividualEditor();
individualEditor.TopLevel = false;
panel1.Controls.Clear();
panel1.Controls.Add(individualEditor);
individualEditor.Show();
}
}
ME_Upload.cs
private void ME_UploadButton_Click(object sender, EventArgs e)
{
OpenFileDialog opf = new OpenFileDialog();
opf.Filter = "Choose Image(*.jpg; *.png; *.gif)|*.jpg; *.png; *.gif";
if (opf.ShowDialog() == DialogResult.OK)
{
ME_ImageEditor ME_ImageEditorConstruct = new ME_ImageEditor();
ME_ImageEditorConstruct.TopLevel = false;
panel1.Controls.Clear(); ///Not Working
panel1.Controls.Add(ME_ImageEditorConstruct); ///Not Working
ME_ImageEditorConstruct.Show();
}
}

//DataUpdate.Visible = true;
//DataUpdate.Top = 0;
//DataUpdate.Left = 0;
DataUpdate.Dock = DockStyle.Fill;
DataUpdate.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
tabPage1.Controls.Add(DataUpdate);
//var SystemSetting = new SystemSetting();
var SystemSetting = new TestForm4();
SystemSetting.TopLevel = false;
//SystemSetting.Visible = true;
//SystemSetting.Top = 0;

SystemSetting.Dock = DockStyle.Fill;
SystemSetting.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;

// In your TestForm3,
private void button1_Click(object sender, EventArgs e)
{
TestForm4 frm = new TestForm4();
frm.owner=this;
frm.Show();

private void button1_Click(object sender, EventArgs e)
{
TestForm3 mainForm=(TestForm3)this.owner;
mainForm.LabelText = textBox1.Text;
}

Switch forms with tab control

I am a beginner in C#, so please bear with me. I have a form where I have a tab control, this tab control has 3 tabs. I am trying to show a form with each tab page. I am able to show a form on the first tab, but for some reason, the other two tabs do not load the forms. This is the code that I have. Am I doing something wrong? Do you have any suggestions?
private void MainTab_Load(object sender, EventArgs e)
{
HomeScreen fHome = new HomeScreen();
fHome.TopLevel = false;
fHome.Visible = true;
fHome.FormBorderStyle = FormBorderStyle.None;
fHome.Dock = DockStyle.Fill;
MainOptions.TabPages[0].Controls.Add(fHome);
}
private void CustomerTab_Click(object sender, EventArgs e)
{
CustomerScreen fCustomer = new CustomerScreen();
fCustomer.TopLevel = false;
fCustomer.Visible = true;
fCustomer.FormBorderStyle = FormBorderStyle.None;
fCustomer.Dock = DockStyle.Fill;
MainOptions.TabPages[1].Controls.Add(fCustomer);
}
edit:
More:
Also, in the tabcontrol- InitializeComponent I have the following
// HomeTab
//
this.HomeTab.Location = new System.Drawing.Point(4, 22);
this.HomeTab.Name = "HomeTab";
this.HomeTab.Size = new System.Drawing.Size(677, 452);
this.HomeTab.TabIndex = 0;
this.HomeTab.Text = "Home";
this.HomeTab.UseVisualStyleBackColor = true;
this.HomeTab.Click += new System.EventHandler(this.MainTab_Load);
//
// CustomerTab
//
this.CustomerTab.Location = new System.Drawing.Point(4, 22);
this.CustomerTab.Name = "CustomerTab";
this.CustomerTab.Padding = new System.Windows.Forms.Padding(3);
this.CustomerTab.Size = new System.Drawing.Size(677, 452);
this.CustomerTab.TabIndex = 1;
this.CustomerTab.Text = "Customer";
this.CustomerTab.UseVisualStyleBackColor = true;
this.CustomerTab.Click += new System.EventHandler(this.CustomerTab_Click);

I think you're just missing the Show() method...
And a suggestion: I don't know what kind of Pattern you're using, but as a beginner, you should declare your forms outside those methods, as a variable within the class scope, so you can access then later...
private HomeScreen fHome = new HomeScreen();
private CustomerScreen fCustomer = new CustomerScreen();
private void MainTab_Load(object sender, EventArgs e)
{
fHome.TopLevel = false;
fHome.Visible = true;
fHome.FormBorderStyle = FormBorderStyle.None;
fHome.Dock = DockStyle.Fill;
MainOptions.TabPages[0].Controls.Add(fHome);
fHome.Show(); // add this
}
private void CustomerTab_Click(object sender, EventArgs e)
{
fCustomer.TopLevel = false;
fCustomer.Visible = true;
fCustomer.FormBorderStyle = FormBorderStyle.None;
fCustomer.Dock = DockStyle.Fill;
MainOptions.TabPages[1].Controls.Add(fCustomer);
fCustomer.Show(); // add this
}
There's a lot to improve here, but that's a start.

Create a button which creates button

I am a begginer in C# and I want to create a button which creates button.
but these buttons never appear...
please find my code :
private void addstrat3_i_Click(object sender, EventArgs e)
{
panel3strat.Width += 200;
Button addstrat3_2 = new Button();
addstrat3_2.Size = new Size(210, 41);
addstrat3_2.Location = new Point(50,50);
addstrat3_2.Visible = true;
}
Thanks a lot

You have to add the button (or any other controls) on the form using the Controls property, for sample:
private void addstrat3_i_Click(object sender, EventArgs e)
{
panel3strat.Width += 200;
Button addstrat3_2 = new Button();
addstrat3_2.Size = new Size(210, 41);
addstrat3_2.Location = new Point(50,50);
addstrat3_2.Visible = true;
// add control
this.Controls.Add(addstrat3_2);
}

You need to add the button to the form.
this.Controls.Add(addstrat3_2);

How to use Multiple forms in one Csharp panel in one Windows Form panel?

I am building a kids learning application, where clicking on a button on panel, I want to show different forms in the same place of the panel. Can you please help with any walk-through or tutorial links?

This question should have been posted on Stackoverflow website rather than here.
But you can use this approach to handle the case.
subForm = new SubFormYouWantToLoad();
subForm.TopLevel = false;
subForm.FormBorderStyle = FormBorderStyle.None;
ContainerPanel.Controls.Add(subForm , 0, 1);
subForm .Visible = true;
You can add this code when you click on the specific button.
Here each subform is added to the Panel as a Control. You should remove the subform from the panel's control list before adding another subform. For this ,it is better to remove,close and dispose the first one.
ContainerPanel.Controls.Remove(activeform);
activeform.Close();
activeform.Dispose();

Instead of Forms use user controls and load them in to panels
Sample if you want to show usercontrol1
panel1.Controls.Clear();
panel1.Visible = true;
UserControl1 usr1 = new UserControl1();
usr1.Show();
panel1.Controls.Add(usr1);
If usercontrol2
panel1.Controls.Clear();
panel1.Visible = true;
UserControl1 usr2 = new UserControl2();
usr2.Show();
panel1.Controls.Add(usr2);

You could create a number of forms as user controls or a control that inheriets from a panel. Then have a parent form with a panel to hold the user controls. You can then change the active user control in the container when the panel needs to be changed.
There is a tutorial on msdn for creating user controls.
http://msdn.microsoft.com/en-us/library/a6h7e207(v=vs.71).aspx

I used this code to close the form on the panel but not worked..
private void button12_Click(object sender, EventArgs e)
{
dontShowPANEL();
//ActiveForm.Close();
MainImaginCp kj = new MainImaginCp();
//kj.Visible = false;
kj.panel2.Controls.Clear();
panel1.Visible = true;
EngABCLearning usr1 = new EngABCLearning();
usr1.Show();
kj.panel2.Controls.Add(usr1);
//kj.Focus();
}
And I used the following code to show the form in the panel.
private void toolStripMenuItem1_LR_ENG_Click(object sender, EventArgs e)
{
//kids.Form2 hj = new kids.Form2();
//hj.Show();
EngABCLearning gh = new EngABCLearning();
//gh.Show();
gh.TopLevel = false;
gh.FormBorderStyle = FormBorderStyle.None;
//Panel2.Controls.Add(subForm, 0, 1);
panel2.Controls.Add(gh);
gh.Visible = true;
}
This is closing my main form and exiting the application.

try this out i have loaded two forms inside a single panel
private void Form1_Load(object sender, EventArgs e)
{
Form2 f1 = new Form2();
f1.TopLevel = false;
f1.AutoScroll = true;
panel1.Controls.Add(f1);
f1.Dock = DockStyle.Left;
f1.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
f1.Show();
//form2
Form3 f2 = new Form3();
f2.TopLevel = false;
f2.AutoScroll = true;
panel1.Controls.Add(f2);
f2.Dock = DockStyle.Left;
f2.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
f2.Show();
}

try this i used this method to load multiple forms at one panel
private Form activeForm = null;
public void FormLoad(Form childForm)
{
if (activeForm != null)
{
activeForm.Close();
}
activeForm = childForm;
childForm.TopLevel = false;
childForm.FormBorderStyle = FormBorderStyle.None;
panelName.Controls.Add(childForm);
childForm.Visible = true;
}
private void YourBtn1_Click(object sender, EventArgs e)
{
FormLoad(new youWantToLoadForm1Name());
}
private void YourBtn2_Click(object sender, EventArgs e)
{
FormLoad(new youWantToLoadForm2Name());
}
