Urgent: Trigger javascript function after bind control

[Guest]

Hi All,

I've a problem here, I want to trigger a javascript function after binding
the ListBox control. Basically the javascript will remove the duplicates
records after recordset is bind in the ListBox control automatically without
users onclick/onchange the ListBox.

I don't want to distinct the records in the SQL query, because I have other
usage for those duplicates records.

How can this be done? Please help, thanks in advance.

Hi Mae,

Does it have to be client-side and right after binding the control?

It's hard to get into a server-side event like that to do client-side stuff.

Why not loop through the items collection on the server-side to remove the
duplicates?

Or, what about running the JavaScript immediately after the page is loaded?
That's far safer:

Can you not use two SQL queries one that returns distinct rows and one
that doesn't and use them accordingly.

Rather than maintaining 2 SPs, could you use the create a DataView from
the binded DataSet? In other words apply your DataView (where you
remove the duplicates) to the DataSet and then bind your list box to the
DataView?
