I create an array of custom objects and bind it to a dropdown box.

SQLObject[] boxes = new SQLObject[] {
      new SQLObject(eRecordType.EMPLOYEE, "SELECT TOP 15 * FROM dbo.Employee"),
      new SQLObject(eRecordType.LOGGER, "SELECT TOP 15 * FROM dbo.Logger")};
ddBindArray.DataSource = boxes;
ddBindArray.DataBind();

Then in the selected index changed event, I want to get the item selected:

protected void ddBindArray_SelectedIndexChanged(object sender, EventArgs e) {

   I tried getting the selected item and casting it...
       SQLObject current = (SQLObject)ddBindArray.SelectedItem;

   I also tried getting the indexed item
       SQLObject current = (SQLObject)ddBindArray.Items[ddBindArray.SelectedIndex];

..but both times I got this error at compile time:

Cannot convert type 'System.Web.UI.WebControls.ListItem' to 'SQLObject'

How can I get the object selected without having to store the original array and refer back to it?

> SQLObject current = (SQLObject)ddBindArray.SelectedItem;
Replaced with:
int index=ddBindArray.SelectedIndex;
SQLObject current=box[index];

but both box's ,ddBindArray's items must be in the same order.

Hope this help

What I was actually looking for is a way to bind the array (or collection) of objects to a control such that I wouldn't have to store and retrieve (probably with Session) the original collection.

When I bind an array to a client control, does that array exist client-side, or does the control only contain the strings which it displays?
