{
if (!binding1.SupportsSearching)
{
_ = MessageBox.Show("Cannot search the list.");
}
else
{
int foundIndex = binding1.Find("Name", textBox1.Text);
if (foundIndex > -1)
{
listBox1.SelectedIndex = foundIndex;
}
else
{
_ = MessageBox.Show("Font was not found.");
}
}
}
Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs) _
Handles button1.Click
If binding1.SupportsSearching <> True Then
MessageBox.Show("Cannot search the list.")
Else
Dim foundIndex As Integer = binding1.Find("Name", textBox1.Text)
If foundIndex > -1 Then
listBox1.SelectedIndex = foundIndex
