When the user chooses an item to purchase they should be able to specify the quantity and the total is specified, the problem is that the quantity does not increase and I don't seem to understand what can be the cause of that.

What I have tried:

I have tried fixing it because I thought it was my database but still it does not give me the correct feedback.

C#

private void PlusOne_Click(object sender, EventArgs e)
{
  foreach (ListViewItem list in listView1.SelectedItems)
  {
    list.SubItems.Add(addBox.Text);

That's not enough information to help you out. Please share the piece of problematic code which may make your question clear.

What kind of magic are we supposed to use to see your code?

Here is the code for the user to enter a value manually into a textBox, and clicking the button (with the product selected) will update the quantity. There's no crash, but it doesn't do anything.

private void PlusOne_Click(object sender, EventArgs e)
{
foreach (ListViewItem list in listView1.SelectedItems)
{
list.SubItems.Add(addBox.Text);
}
}

private void addBox_TextChanged(object sender, EventArgs e)
{
int addOne = int.Parse(addBox.Text);
}

What are you doing addOne variable in addBox_TextCahnged function?

Simphiwe_Magubane 16-Sep-19 17:19pm

The TextChanged event is for when the content of the Textbox changes and only if it is changed by the user.

I got that thing you explained about "Textbox changes" already. But what I was telling you, You did not do anything with your changed text except for putting it in a integer variable. You need to do something.

FYI, C# is not magic.

Your code doesn't make much sense to me. When addBox text changes you set a variable named addOne to the number in the addBox.Text. Which is fine, but you don't do anything with the addOne variable. Its only locally scoped as well so you set an unused variable to the number in the text box. Seems like a waste of processing time. No where in the code are you adding up totals of any numbers. Which is what it sounds like you want to do??

Just debug the code and find the issue. That should be very simple. Are you the one who wrote the code?
