Solution 1

The question needs to be clarified.

I understand English may not be your first language, and we generally try to help even when the question is ambiguous like this.

Could you supply more detail or rephrase the question to be more specific.

Solution 2

You need to use KeyPress event. After Key Press, compare records with combobox.Text and display only those which starts with the string present in comboBox.Text.

This answer comes from a totally brainless 'learning' program I wrote. But this method does exactly what you want (Just ignore the details of my data.)

<pre lang="cs">
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
int which = Convert.ToInt32(comboBox1.SelectedItem.ToString());
var tolearnrow = from q in Leitner.ToLearn
where q.Id == which
select q;

foreach (var onetolearn in tolearnrow)
{
string strTry = onetolearn[0].ToString();
label6.Text = onetolearn.Id.ToString();
label7.Text = onetolearn.Part_Id.ToString();
label12.Text = onetolearn.Side1;
label10.Text = onetolearn.Side2;
label9.Text = onetolearn.Side3;
label8.Text = onetolearn.A_B_TestDate;
label19.Text = onetolearn.A_C_TestDate;
label20.Text = onetolearn.B_A_TestDate;
label21.Text = onetolearn.B_C_TestDate;
label22.Text = onetolearn.C_A_TestDate;
label23.Text = onetolearn.C_B_TestDate;
label29.Text = onetolearn.A_B_GoodCount.ToString();
label28.Text = onetolearn.A_C_GoodCount.ToString();
label27.Text = onetolearn.B_A_GoodCount.ToString();
label26.Text = onetolearn.B_C_GoodCount.ToString();
label25.Text = onetolearn.C_A_GoodCount.ToString();
label24.Text = onetolearn.C_B_GoodCount.ToString();
label35.Text = onetolearn.A_B_BadCount.ToString();
label34.Text = onetolearn.A_C_BadCount.ToString();
label33.Text = onetolearn.B_A_BadCount.ToString();
label32.Text = onetolearn.B_C_BadCount.ToString();
label31.Text = onetolearn.C_A_BadCount.ToString();
label30.Text = onetolearn.C_B_BadCount.ToString();
}
}</pre>
