Examples

The following code example demonstrates how to use the SupportsSearching member. For the complete example see the class overview topic.

private void button1_Click(object sender, EventArgs e)
{
    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
            Else
                MessageBox.Show("Font was not found.")
            End If
        End If

    End Sub
End Class

Remarks

If the data source is not an IBindingList, SupportsSearching always returns false.
