How to hide and show a panel by clicking a button in C#

I have three panels and three buttons. Upon clicking button1 I want to show Panel1 and hide Panel2 and Panel3.
The same process with the other buttons and panels. How can I do this?
I'm using a Window Forms application written in C#/.NET. This code is not working very well, because only two panels are showing.
private void frmMain_Load(object sender, EventArgs e)
{
pnlItems.Visible = true;
pnlCustomer.Visible = false;
pnlPOS.Visible = false;
}
private void btnItems_Click(object sender, EventArgs e)
{
pnlItems.Visible = true;
pnlCustomer.Visible = false;
pnlPOS.Visible = false;
}
private void btnCustomers_Click(object sender, EventArgs e)
{
pnlCustomer.Visible = true;
pnlItems.Visible = false;
pnlPOS.Visible = false;
}
private void btnPOS_Click(object sender, EventArgs e)
{
pnlPOS.Visible = true;
pnlCustomer.Visible = false;
pnlItems.Visible = false;
}

private void frmMain_Load(object sender, EventArgs e)
{
pnlItems.Visible = true;
pnlCustomer.Visible = false;
pnlPOS.Visible = false;
}
private void btnItems_Click(object sender, EventArgs e)
{
if(pnlItems.Visible != true)
{
pnlItems.Visible = true;
pnlCustomer.Visible = false;
pnlPOS.Visible = false;
}
}
private void btnCustomers_Click(object sender, EventArgs e)
{
if(pnlCustomer.Visible != true)
{
pnlCustomer.Visible = true;
pnlItems.Visible = false;
pnlPOS.Visible = false;
}
}
private void btnPOS_Click(object sender, EventArgs e)
{
if(pnlPOS.Visible != true)
{
pnlPOS.Visible = true;
pnlCustomer.Visible = false;
pnlItems.Visible = false;
}
}
Here I have updated the conditional statement for if your panel is not visible then act. I hope this will work.

Update button for GridView

I'm trying to create an Update button to let me insert data into a gridview and after creating the class, the button does nothing and I don't understand why that is the case.
private void Basic()
{
// no updates allowed
dataGridView1.AllowUserToAddRows = false;
dataGridView1.AllowUserToDeleteRows = false;
dataGridView1.ReadOnly = true;
//UpdateButton is available
UpdateButton.Enabled = true;
//Save and Cancel Unavailable
SaveButton.Visible = false;
CancelButton.Visible = false;
sTableAdapter.Fill(dataSet1.S);
}
This is the UpdateButton Event
private void UpdateButton_Click(Object sender, EventArgs e)
{
dataGridView1.AllowUserToAddRows = true;
dataGridView1.AllowUserToDeleteRows = true;
dataGridView1.ReadOnly = false;
UpdateButton.Enabled = false;
SaveButton.Visible = true;
CancelButton.Visible = true;
}
And this should be the update class:
this.UpdateButton.Location = new System.Drawing.Point(12, 63);
this.UpdateButton.Name = "UpdateButton";
this.UpdateButton.Size = new System.Drawing.Size(103, 23);
this.UpdateButton.TabIndex = 0;
this.UpdateButton.Text = "Update";
this.UpdateButton.UseVisualStyleBackColor = true;
The connection is made with a accdb.
The Update button isn't working on click, what did I do wrong?

Enable and Disable buttons, labels based on some conditions

I have 5 buttons and 5 labels next to each button. When i run the app i expect the first button to be enabled and the the rest disabled and greyed out with the labels. after i click the first button it should disable with the label and enable the second button, and so forth with all the other buttons.
this way is to long, is there a better way of doing this?
private void Form1_Load(object sender, EventArgs e)
{
btn1.Enabled = true;
btn2.Enabled = false;
btn3.Enabled = false;
btn4.Enabled = false;
btn5.Enabled = false;
lblStep1.Enabled = true;
lblStep2.Enabled = false;
lblStep3.Enabled = false;
lblStep4.Enabled = false;
lblStep5.Enabled = false;
}
private void btn1_Click(object sender, EventArgs e)
{
btn1.Enabled = false;
btn2.Enabled = true;
btn3.Enabled = false;
btn4.Enabled = false;
btn5.Enabled = false;
lblStep1.Enabled = false;
lblStep2.Enabled = true;
lblStep3.Enabled = false;
lblStep4.Enabled = false;
lblStep5.Enabled = false;
}
private void btn2_Click(object sender, EventArgs e)
{
btn1.Enabled = false;
btn2.Enabled = false;
btn3.Enabled = true;
btn4.Enabled = false;
btn5.Enabled = false;
lblStep1.Enabled = false;
lblStep2.Enabled = false;
lblStep3.Enabled = true;
lblStep4.Enabled = false;
lblStep5.Enabled = false;
}
}
private void btn3_Click(object sender, EventArgs e)
{
btn1.Enabled = false;
btn2.Enabled = false;
btn3.Enabled = false;
btn4.Enabled = true;
btn5.Enabled = false;
lblStep1.Enabled = false;
lblStep2.Enabled = false;
lblStep3.Enabled = false;
lblStep4.Enabled = true;
lblStep5.Enabled = false;
}
private void btn4_Click(object sender, EventArgs e)
{
btn1.Enabled = false;
btn2.Enabled = false;
btn3.Enabled = false;
btn4.Enabled = false;
btn5.Enabled = true;
lblStep1.Enabled = false;
lblStep2.Enabled = false;
lblStep3.Enabled = false;
lblStep4.Enabled = false;
lblStep5.Enabled = true;
}
private void btn5_Click(object sender, EventArgs e)
{
btn1.Enabled = true;
btn2.Enabled = false;
btn3.Enabled = false;
btn4.Enabled = false;
btn5.Enabled = false;
lblStep1.Enabled = true;
lblStep2.Enabled = false;
lblStep3.Enabled = false;
lblStep4.Enabled = false;
lblStep5.Enabled = false;
}

Let all these buttons and labels are inside a container(if it doesn't mean that you can use this.Controls as well if the form contains these buttons and labels only). Let it be pnlContainer, Now you can try something like this:
public void ButtonController(Button buttonToEnable, Label labelToenable)
{
foreach (Control ctrl in panel1.Controls)
{
if (ctrl == buttonToEnable || ctrl == labelToenable)
{
ctrl.Enabled = true;
}
else
{
ctrl.Enabled = false;
}
}
}
So in Form1_Load you want to enable btn1 and lblStep1 so the call should be :
ButtonController(btn1,lblStep1);
For btn1_Click the method call will be like ButtonController(btn2,lblStep2);. in short, you can pass the button and label that you want to enable to this method, which will disable rest of controls in the container.

how can disable a textbox in class asp.net

private void txtenable (Boolean txtenable)
{
if(txtenable== false)
{
txtname.Enabled = false;
txtTel.Enabled = false;
txtmobile.Enabled = false;
txtAdress.Enabled = false;
}
else
{
txtname.Enabled = true;
txtTel.Enabled = true;
txtmobile.Enabled = true;
txtAdress.Enabled = true;
}
}
I want use this class but i can not call textboxes. How can call textbox in class?

First you need to be able to accept the TextBox objects within the class, then you can manipulate them how you see fit. I haven't actually tried this, but this is how I would go about setting it up.
public class YourClass
{
TextBox txtName;
TextBox txtTel;
TextBox txtMobile;
TextBox txtAddress;
private void txtenable (Boolean txtenable, TextBox txtName, TextBox txtTel, TextBox txtMobile, TextBox txtAddress)
{
if(txtenable== false)
{
txtName.Enabled = false;
txtTel.Enabled = false;
txtMobile.Enabled = false;
txtAddress.Enabled = false;
}
else
{
txtName.Enabled = true;
txtTel.Enabled = true;
txtMobile.Enabled = true;
txtAddress.Enabled = true;
}
}
In order for you to access the textboxes from within your class you will need to pass them such as:
public class OtherClassContainingTextBoxes
{
private void SomeEvent(object sender, EventArgs e){
txtenable(true, txtName, txtTel, txtMobile, txtAddress);
}
However, based on the example provided, I am unsure why you wouldn't do this in a method within the class you have your textboxes.
You could do something on pageload:
protected void Page_Load(object sender, EventArgs e)
{
if (Session["enable"] == false){
txtenable(false);
}else{
txtenable(true);
}
}
private void txtenable (Boolean txtenable)
{
if(txtenable== false)
{
txtName.Enabled = false;
txtTel.Enabled = false;
txtMobile.Enabled = false;
txtAddress.Enabled = false;
}
else
{
txtName.Enabled = true;
txtTel.Enabled = true;
txtMobile.Enabled = true;
txtAddress.Enabled = true;
}
}

shivery effect of the GUI prepared using C# windows forms

For file transfer between the client and server systems we have a GUI designed on the client system using C# windows forms. We have added a lot of background images and text boxes to make the GUI impressive. But whenever we execute the client code, the GUI takes a few seconds to load itself and be stable , before a choice from the GUI can be made. This happens after every request made from the client side GUI.(its like all the form elements vanish and appear again in a short span of time ). Please help with this. May i know the reason for it.

Try using below code in your form constructor.
this.DoubleBuffered = true;
It should improve some performance. Windows forms are not made to display lot of images overlapped on each other.
