Question

How to compare the data with listbox and textbox?

Not sure what you mean; here is a way to search for a match and a way to select (highlight) a match: // search for a match private void button1_Click( object sender EventArgs e) { foreach ( string s in listBox1.Items) { if (s == textBox1.Text) MessageBox .Show( Found:  + s); } } // select the match private void button2_Click( object sender EventArgs e) { for ( int i=0; i { if (listBox1.Items[i].ToString() == textBox1.Text) listBox1.SelectedIndex = i; } }
