Filtering ListBox entries by string

Question

0.00/5 (No votes)

See more:

There are 4 items on my form:
- two listboxes
- one button
- one text box
I have a listbox 'A' with many items and
I need a item in listbox 'B' from listbox 'A'.

The following are the steps I'd like to perform:
1)enter a word or character in a textbox
2)press a button
3)The list appearing in ListBox 'B' should be composed of entries from
ListBox 'A' if these entries start with the string typed in the
Textbox

I need some help in how to get the entries from ListBox 'A' that match the string in the TextBox into ListBox 'B'

Please help me solve this.

Thank you!

Solution 1

Try:

C#

string search = textBox1.Text;
listBox2.Items.Clear();
foreach (string val in listBox1.Items)
    {
    if (val.StartsWith(search))
        {
        listBox2.Items.Add(val);
        }
    }
