Question

Using the following code, every time I hit the submit button the values all go back to 0

        If txtBedrooms.Text = String.Empty Then
            MessageBox.Show("Please enter a bedroom 0 or greater")
            Exit Sub
        ElseIf Not IsNumeric(txtBedrooms.Text) Then
            MessageBox.Show("Please enter a bedroom 0 or greater")
            Exit Sub
        ElseIf txtBedrooms.Text < 0 Then
            MessageBox.Show("Please enter a bedroom 0 or greater")
            Exit Sub
        Else
            txtBedrooms.Text = bedrooms.ToString
        End If

Where am I going wrong?

Answer 1

Have you set a value for bedrooms? It is not in the code you submitted?

I “think” you are trying to set bedrooms to the value of txtBedrooms.
If that is the case, the assignment is the wrong way round and needs switching to

bedrooms = Convert.ToInt32(txtBedrooms.Text);
