示例1: UOMID_SelectedIndexChanged
protected virtual void UOMID_SelectedIndexChanged(object sender, EventArgs args)
{
// If a large list selector or a Quick Add link is used, the dropdown list
// will contain an item that was not in the original (smaller) list. During postbacks,
// this new item will not be in the list - since the list is based on the original values
// read from the database. This function adds the value back if necessary.
// In addition, This dropdown can be used on make/model/year style dropdowns. Make filters the result of Model.
// Mode filters the result of Year. When users change the value of Make, Model and Year are repopulated.
// When this function is fire for Make or Model, we don't want the following code executed.
// Therefore, we check this situation using Items.Count > 1
// Since both of these feature use javascript to fire this event, this can be skip if the event is fired by server side,
// so we check if it is not postback
if (!this.Page.IsPostBack && this.UOMID.Items.Count > 1)
