Hi All

I have a listview with the following column headers:
ProductName
QTY
TotalAmount

I have a button AddToCart with the following code:

C#

{
                   
                    ListViewItem lst = new ListViewItem();
                    
                    lst.SubItems.Add(txtProductName.Text);
                    lst.SubItems.Add(txtQTY.Text);
                    lst.SubItems.Add(txtTotalAmount.Text);
                    lst.SubItems.Add(txtPid.Text);
                    lst.SubItems.Add(txtPrice.Text);

                    RegWindow.Items.Add(lst);
                    
                   
                    txtProductCode.Text = "";
                    txtProductName.Text = "";
                    txtQTY.Text = "";
                   
                    txtPrice.Text = "";
                  
                    txtPid.Text = "";
                    txtTotalAmount.Text = "";
                    return;
                }

This fills the listview with the correct info retrieved from textboxes

The problem is that above code does not add anything after entering new values in the textboxes

What do i need to have 2 rows in the listview after AddToCart is pressed again with new textbox values

This is a c# winform application

What I have tried:

I had similar vb.net code which worked 100%

I tried coverting the vb code into c# but it does not work
I have only recently started to code in C#
Thank you in advance

Below the vb code:

VB.NET

Try

            Dim temp As Integer
            temp = ListView1.Items.Count()
            If temp = 0 Then

                'lst.SubItems.Add(txtProductName.Text)

If I understand you well, you want the content of those textBoxes to be added to the ListView each time the AddToCart button is been clicked. right?

if yes then handle the Click Event of the AddToCart button and paste your first c# code in it.
for example

C#

private void AddToCart_Click(object sender, EventArgs e)
{
   ListViewItem lst = new ListViewItem();
                    
   lst.SubItems.Add(txtProductName.Text);
   lst.SubItems.Add(txtQTY.Text);
   lst.SubItems.Add(txtTotalAmount.Text);
   lst.SubItems.Add(txtPid.Text);
   lst.SubItems.Add(txtPrice.Text);
 
   RegWindow.Items.Add(lst);
                    
                   
   txtProductCode.Text = "";
   txtProductName.Text = "";
   txtQTY.Text = "";                
   txtPrice.Text = "";
   txtPid.Text = "";
   txtTotalAmount.Text = "";

   return;
}

I see that i had below code (From vb)
int temp;
temp = RegWindow.Items.Count;
if (temp == 0)

i removed this piece and it solved my problem

Thanks
