Pause user from Closing multiple docks

[Bobby]

I have an issue with the dock command.Name="close".
If the user clicks the close button quickly on multiple docks, it will not have enough time to finish the process before skiping on over to the next dock. How can I prevent the user from clicking the close button or make the sub finish on process before starting another.

Thank you
Bobby

Hi Bobby,

You could set the CommandsAutoPostBack property to false in order to prevent postback when the user clicks on the command icon. This way the command event handler would be called only when a postback is made by another control on the page and you will be able to execute your code for all docks.

If you prevent the default behavior when clicking on a command icon you will in fact degrade the user experience because when you click on the icon some action should take place. But if you want to prevent the users from clicking on the command icons you could attach an onclick event handler to the commands container of the dock. The code below shows how to get the commands container:

var commandsContainer = dock.get_commandsContainer();

I hope this helps. If you have further questions, please, feel free to contact us at any time.
