Why Showing empty windows form not showing any controls in c# project

I designed some Windows form a few days back. After a few days, all controls have disappeared from the form. It seems just like a new blank form. This form is the startup form and it is there in the Program.cs file. Also, I've not edited the designer.cs file manually.
here is my FrmMain.cs code
public partial class FrmMain : Form
{
private bool isCollapsed=true;
public FrmMain()
{
InitializeComponent();
GetDateAndTime();
sidePanel.Top = btnHome.Top;
}
private void GetDateAndTime()
{
try {
timer1.Start();
lblTme.Text = DateTime.Now.ToLongTimeString();
lblDate.Text = DateTime.Now.ToLongDateString();
}
catch (Exception e) {
Clipboard.SetText(e.Message);
}
}
private void timer1_Tick(object sender, EventArgs e)
{
lblTme.Text = DateTime.Now.ToLongTimeString();
timer1.Start();
}
private void btnSettings_Click(object sender, EventArgs e)
{
sidePanel.Top = panelCollap.Top;
timer2.Start();
}
private void timer2_Tick(object sender, EventArgs e)
{
if (isCollapsed)
{
panelCollap.Height += 10;
if (panelCollap.Size == panelCollap.MaximumSize) {
timer2.Stop();
isCollapsed = false;
}
}
else
{
panelCollap.Height -= 10;
if (panelCollap.Size == panelCollap.MinimumSize)
{
timer2.Stop();
isCollapsed = true;
}
}
}
}
Here is the Designer.cs
partial class FrmMain
{
private System.ComponentModel.IContainer components = null;
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);

Thanks for helping me.

You have a weird uncommented </param> at the line 6 of your Designer.cs file. You probably left it around after removing those button. Just remove it and it should work fine.

How to access text button outside Form.cs class (I mean in Program.cs)

I have created a Form in c# windows. My form contains a button and a text box and it 's name is textbox2 here and it contains code like this in Form1.Designer.cs :
this.textBox2.Location = new System.Drawing.Point(683, 14);
this.textBox2.Name = "textBox2";
this.textBox2.Size = new System.Drawing.Size(100, 20);
this.textBox2.TabIndex = 22;
Now i have created another class called Programss.cs which will do some task and as the task finished i want to print on my form something like this:
textBox2.txt= "Task finished"; //it should print on the textbox of my Form1.cs
How to access this textBox2(which can only be accessed currently in Form1.Designer.cs) in Programss.cs and my other classes ?
EDIT: After Philip Stuyck's comments:
Here is my Form1.cs code :
namespace S
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
//please see here
public string TextMessage
{
get { return textBox3.Text; }
set { textBox3.Text = value; }
}
private void btnStart_Click(object sender, EventArgs e)
{
btnStart.Enabled = false;
// StartServer();
}
private void btnClose_Click(object sender, EventArgs e)
{
}
}
}
And Program.cs is :
namespace Senter code here
{
class Program
{
/// <summary>

{

It dont give any error but it do not print anything in textBox3 .
NOTE: Please note that first i run the winform code i click a button and when i click the button some proccess will run which will further print the text in the textbox. (I feel like my textmessage is not intialized by my message passed to it).

Make sure that textBox2 is public.(can be done in the designer)
Keep a reference to Form1 when you create it and access textBox2 via that reference.
Form1 theForm = new Form1();
... //do stuff
theForm.textBox2.Text = "Task finished";
This is not the most elegant approach to this, but it should work.
An alternative is like this :
public partial class Form1{
public string TextMessage{
get{
return textBox2.Text;
}
set{
textBox2.Text = value;
}
}
}
and in program.cs
Form1 theForm = new Form1();
... //do stuff
theForm.TextMessage = "Task finished";
your code will not work because
Form1 theForm = new Form1();
theForm.TextMessage = "Task finished";
is never executed.
Application.Run(new Form1());
returns only when the form is closed and then the application will end.
Following will work:
Form1 theForm = new Form1();
theForm.TextMessage = "Task finished";
Application.Run(theForm);
But I have the feeling you don't quite understand the framework.
Application.run, will make your application enter into a message loop which makes the application receive window messages.

One way you could do this is to have a method accessible in your Form1 that sets the textBox name to whatever you want. For instance:
public static void SetText (string message)
{
TextBox2.Text = message;
}
You would then call this from your Program.cs class:
Form1.SetText("Whatever text you want the text on the Form1 - TextBox2 to say");
This is the poor man's way of changing the text. There is a more detailed explanation on this other post if you need more details.

As I understood you want to print end result on textBox2.txt textbox, right? So you want to execute some methods on Programss.cs and once execution is finished you want to show "Task finished" on textBox2.txt.
If I am not wrong, what you have to do is return a value from a method from Programss.cs class. You have to call this method from Form1.Designer.cs class. Based on return value you can do whatever you want.
Hope this will be helpful.

You are creating two separate forms, setting text on the second, and expecting it to appear on the first.
Do this:
Form1 theForm = new Form1();
theForm.TextMessage = "Task finished";
Application.Run(theForm);

Winforms Designer errors when changing accessibility of a control

I decided to change a listBox1 item in my form1 designer to public static instead of private to access it on another form. And once I had done that It had errored and not allowed me to changed things on the form itself and just tells me this error at the top
The variable 'listBox1' is either undeclared or was never assigned.
The error is shown on the following line
this.panel1.Controls.Add(listBox1);
My Designer for my form below:

Change this back to what it was previously: (public to private, remove static)
public static System.Windows.Forms.ListBox listBox1;
Add this in the code-behind in your Form: (you don't need a setter since you won't be creating a new ListBox from the other Forms... I hope)
public ListBox MyListBox
{
get { return listBox1; }
}
Now in other Forms (assuming they're being created by some process in your first Form), you'll pass a reference to the current instance of your Form with the ListBox on it, so you can actually access the public property you just created:
public class SecondForm : Form
{
public SecondForm(FirstForm firstForm)
{
// do something with firstForm.MyListBox
}
}
Lastly, I'd say be careful how much you do this. Forms being able to access each other's controls seems messy to me. If you added more details about exactly what you're trying to accomplish with this, we might be able to provide a better alternative.

Your issue is that you changed the code in the designer file so that listBox1 is now static. You can't do this because the designer must be able to instantiate an instance of ListBox.
What it sounds like you are trying to do is you are trying to modify the listbox from another form. The proper way you should do this is through properties. In your code (not the designer code, but the code behind code), have something like this:
public ListBox MyListBox
{
get
{
return listBox1;
}
}

You shouldn't change anything in the .Designer.cs file. If you want to change access modifiers you should do so through the Properties window.
That being said, your public change was fine, you just can't make it static. For the designer to function all the controls in the form must be independent to each instantiation.
// what the code will look like when you change it from the Properties window
public System.Windows.Forms.ListBox listBox1;
If you were to make the ListBox static, you would access it like
ListBox listbox = Inside.listBox1;
which doesn't make much sense if you have more than one Inside form floating around. If you make it non-static you can still access it from wherever you want as long as you have an instance of the Inside class.
Inside inside = new Inside();
ListBox listbox = inside.listBox1;

C# WinForms - how to send updates from DataGridView to DataBase

I have a .mdb file with a Customers table and an Agents table. The only thing that the Agents table does as yet is populate the Agent dropdown for each customer...
I have a DataGridView linked to the customerBindingSource. The customerBindingSource has DataMember set to Customer and DataSource set to bindingSource1. This has the DataSource set to customerAppDS21. If I select customerAppDS21 and click Edit in DataSet Designer I can quite clearly see that there is a Customer table and Agent table. These were dragged directly from the Data.mdf > Tables folder. I have been through the Configure wizard and checked that the Update, Insert and Delete commands are generated correctly.
I am setting the unique ID (GUID) when the user leaves a row or adds a row (I dont think both are needed, but I very much doubt this is the cause of the problem). The user can update or add as many rows as possible. When the user clicks the Save button it calls customerTableAdapter.Update(customerAppDS21.Customer);. All the events are definitely wired up correctly.
The problem is basically that the DataSet appears to get updated but the database itself is not updated. I can close the program and reload it straight away and the data is there. However if I make any changes to the code and then recompile and load the program all the data is gone. This is what makes me think the DataSet is being updated but not the database.
Does anyone have any idea how to solve the problem? I have tried adding the .acceptChanges(); line both before and after the .Update(bla); line, with no success. I have also tried calling customerBindingSource.EndEdit(); and bindingSource1.EndEdit(); before the .Update(bla); line.
Any help with this would be greatly appreciated. I have had this problem for 2 days now and tried alsorts of tutorials to get a hint on where I am going wrong.
Regards,
Richard
Update: Code below...
void button1_Click(object sender, EventArgs e)
{
Validate();
customerBindingSource.EndEdit();
customerTableAdapter.Update(customerAppDS21.Customer);
}
void grdCustomers_RowLeave(object sender, DataGridViewCellEventArgs e)
{
DataGridViewRow gvr = grdCustomers.Rows[e.RowIndex];
if (gvr.Cells[0].Value == null)
{
String g = Guid.NewGuid().ToString();
gvr.Cells[0].Value = g;
}
else
{
String currID = gvr.Cells[0].Value.ToString();
if (currID.Equals(""))
{
String g = Guid.NewGuid().ToString();
gvr.Cells[0].Value = g;
}
}
}
void grdCustomers_UserAddedRow(object sender, DataGridViewRowEventArgs e)
{
DataGridViewRow gvr = grdCustomers.Rows[grdCustomers.SelectedCells[0].RowIndex];
if (gvr.Cells[0].Value == null)
{
String g = Guid.NewGuid().ToString();
gvr.Cells[0].Value = g;
}
else
{
String currID = gvr.Cells[0].Value.ToString();
if (currID.Equals(""))
{
String g = Guid.NewGuid().ToString();
gvr.Cells[0].Value = g;
}
}
