Hi,

I have a query regarding Rad search box. Suppose I'm typing "SCOTT" in the search area. In the firebug console I found 5 different requests to the server. What I need to know is while typing continuously, how can I make the searchbox abort "s", "sc", "sco", "scot" requests and accept only "scott" as the search term so that the server is hit only once and not 5 times.

I have used Ajaxcontroltoolkit autocomplete before which has the same functionality of aborting requests. How can I achieve the same for rad search box. Any idea?

Thanks
Abi

Hello,

One possible way to achieve similar behavior is to cancel the OnClientDataRequesting event according to your custom scenario or to set the MinFilterLength property to 5 if you want to search all the time after the 5th character.

Hello Plamen,

In the client event that you suggested, how do I ignore the all keypresses and accept the last keypress and text only?

Unfortunately I cannot set minimum filter length to 5, it has to be 1 in my application scenario.

Hi,

Let me elaborate a little bit - the onClientRequesting event is thrown on every letter that is typed and you can cancel the request only according the text that is already typed. Unfortunately there is no way to prevent the request unless you can check it at that point in the event and cancel it.

Hope this information will be helpful.
