Stop running this script? and DropDownClosed event
posted

1) My WebDropDown has multi-select checkbox functionality with “Select All” feature implemented through the client-side SelectionChanged event.

 

2) Now if I implement the server-side OnSelectionChanged event by enabling the AutoPostBackFlags-SelectionChanged=”On”, on selecting an element I get a pop-up error saying “Stop running this script? A script on this page is causing Internet Explorer to run slowly. If it continues to run, your computer may become unresponsive.” Also the event gets fired after every selection whereas we want the event to execute only after all the selections are done and when the dropdown is closed.

 

3) I tried implementing this solution from the forum but it doesn’t help - http://community.infragistics.com/forums/t/32575.aspx

 

    <script type="text/javascript">

 

        function selectedIndexChanged(sender, eventArgs) {

            /*

*/

        }

 

        function dropDownClosed(sender, args) {

            var dd = sender._callbackManager.createCallbackObject();

            sender._callbackManager.execute(dd, true);

        }

 

    </script>

 

<ig:WebDropDown ID="WebDropDown1" runat="server" Width="200px" EnableMultipleSelection="True" EnableClosingDropDownOnSelect="False" OnSelectionChanged="WebDropDown1_SelectionChanged">

<ClientEvents SelectionChanged="selectedIndexChanged" DropDownClosed="dropDownClosed" />

</ig:WebDropDown>

 

This fires the server-side event after the selections are done and when the dropdown is closed but leaves the dropdown still open.

I will appreciate any help from the user community!
