Default Problem with updating the detailsview control

Hi..

Here i ended up in very bad situation. i will try to explain the problem here. In our webapp development we are using detailsview controls to display one record. Mind it, that DetailsView control is not bounded to sqlDataSourse or else.. its DataSource is Dataset which is generated dynamically.

On the Edit i have added dropdowlists dynamically loading them from the database. it works fine. but the problem is. when i click on the update i cant see the just added dropdownlist in the Detailsview control. This is really wierd way of behaving.

Please i need help..
suggestion will be appriciated.
thanks
Rake

You have to specify in the DetailsView control the Item events with something like this:

<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" DataKeyNames="AgentID"
            OnItemUpdated="Agency_ItemUpdated"
            OnItemInserted="Agency_ItemInserted"
            OnItemDeleted="Agency_ItemDeleted" ...

and then rebind your drop down list data in the events with your code with something like this:

protected void Agency_ItemUpdated(object sender, DetailsViewUpdatedEventArgs e)
    {
        drpAgencies.DataBind();
    }
    protected void Agency_ItemInserted(object sender, DetailsViewInsertedEventArgs e)
    {
        drpAgencies.DataBind();
    }
    protected void Agency_ItemDeleted(object sender, DetailsViewDeletedEventArgs e)
    {
        drpAgencies.DataBind();
    }

Make sure you use the DetailsViewDeletedEventArgs so the item events will fire from the DetailsView control.
