Comparing a combobox selected item With textbox1 if value same

then this should show
MessageBox.Show("Duplicate Entry", "OK!", MessageBoxButtons.OK, MessageBoxIcon.Information);

the textbox reads from listview1 columns
then must compare if the values are the same

then i can only
activate btnSave

What I have tried:

if (CboBINinout.SelectedItem == txtINOUT.Text)
{
btnOUT.Enabled = false;
}

You need the value of the ComboBox item as a string, in order to compare it to the contents of the TextBox.

if (CboBINinout.SelectedItem.ToString().Trim() == txtINOUT.Text)
{
btnOUT.Enabled = false;
}
if (CboBINinout.SelectedItem.ToString().Trim() != txtINOUT.Text)
{
btnOUT.Enabled = true;
}

Never heard of the else clause? :)

Or even shorter:

btnOUT.Enabled = (CboBINinout.SelectedItem.ToString().Trim() != txtINOUT.Text);
