Adding text to a listbox

Adding text to a listbox

• pgoel6uc

  I wasn't talking about a Textbox control, but a string variable. The variable is recieving a value from an object successfully, but will not add it to a listbox for whatever reason.

  it should do - what happens when you add it Any object you can add into the listbox as the Add() method takes in an object

  When I try to add it nothing happens, no Exception error or anything.

  Did you try to add a string value like "hello" and see what happends. Maybe you are adding values in wrong listbox. Play with your code when you have such unpredictable situation. Maybe your listbox don't shows items, or lisbox is disabled.

  ok the problem is simple. The user creates another main form instance in the other form "Add Items" and adds items to this new main form instance - this will not work. It will continue to operate but since the original existing main form is "alive", you are not dealing/handling with it but creating a new instance (another instance) of the main form.

  You need to reference the main form into this "Add Items" form and add the items as you have done in the code snippet:

  frmMain mainForm = new frmMain(); //this needs to be taken out

  MessageBox.Show("" + i_currentItem);

  MessageBox.Show("Item Name: " + newItem.Get_itemName());

  mainForm.Set_item(newItem, mainForm.Get_numItems());

  So, read the thread below on how to pass a reference of an object, your main form in this case, to this "Add Items" form, then simply access it (access the main form) in the "Add Items" form to add the items to the main form:

  should be:

  this.listBox1.Items.Add(theTextBox.Text);

  textboxes are controls, to get or set its textual property, use the "Text" property of the textbox control and most text based controls (combobox, label, textbox etc...)
