Here is an example to find the value in ListBox according to the text of Text box.
means when you type any character or word in textbox the matched value will be select in list box-
this 4 lines of code will remove your all headache to apply the incremental search option on listbox-
on TextBox's TextChangedEvent code like this-
private void textBox1_TextChanged(object sender, EventArgs e)
{
int index = listBox1.FindString(this.textBox1.Text);
if (0 <= index)
{
listBox1.SelectedIndex = index;
}
}

Hi if you are working on the mobile application development platform for window 7. Then please make sure that you are binding the control listbox through observablecollecton. Apply filter on the observablecollection through linq ...as following
ReplyDeleteprivate void textBox1_TextChanged(object sender, EventArgs e)
{
int index = observablecollection = observablecollection.where(obcoltypeobj=>obcoltypeobj.fielname.startswith(this.textBox1.Text)).ToList();
}
now the above will show the filtered data in the listbox... hope you are well aware of the linq to collections.
pincode lookup:-
