C#

protected void Button1_Click(object sender, EventArgs e)
{
    // Gets the visible index of the required card.
    int cardIndex = ASPxCardView1.FindVisibleIndexByKeyValue("OLDWO");
    if (cardIndex == ASPxCardView.InvalidCardIndex) return;
    if (!IsCardVisibleOnScreen(cardIndex)) {
        // Switches to the page that contains the required card.
        GoToPage(cardIndex);
    }
    // Focuses the card with the specified index.
    ASPxCardView1.FocusedCardIndex = cardIndex;
}

bool IsCardVisibleOnScreen(int cardIndex)
{
    int startIndex = ASPxCardView1.PageIndex * ASPxCardView1.SettingsPager.PageSize;
    int endIndex = startIndex + ASPxCardView1.SettingsPager.PageSize;
    return cardIndex >= startIndex && cardIndex < endIndex;
}
void GoToPage(int cardIndex)
{
    ASPxCardView1.PageIndex = cardIndex / ASPxCardView1.SettingsPager.PageSize;
}
