I am noticing that the grid seems to be firing previously fired event when the grid sits in and update panel.   I have a WebDropDown defined as follows:

<ig:WebDropDown ID="wddTearSheetLevel" runat="server" Width="300px"

AutoPostBack="True" onselectionchanged="wddTearSheetLevel_SelectionChanged">

<Items>

<ig:DropDownItem Selected="False" Text="Security Level" Value="SEC_LEVEL">

</ig:DropDownItem>

<ig:DropDownItem Selected="False" Text="Peer Group" Value="PEER_GROUP">

</ig:DropDownItem>

<ig:DropDownItem Selected="False" Text="Security Classification"

Value="Q_SEC_CODE">

</ig:DropDownItem>

</Items>

</ig:WebDropDown>

Update Panel Trigger, which fires on the selection change of the dropdown.

<Triggers>

<asp:AsyncPostBackTrigger ControlID="wddTearSheetLevel" EventName="SelectionChanged" />

</Triggers>

If i change selection in the grid, the change gets posted just fine.  When the new selectection come up and i decided to delete a row in the grid.  The selection event get fired again....

what gives?
