Show search results in real-time as you type

I am currently developing a SharePoint 2007 web part using Visual Studio. The main goal of this web part is to search a SharePoint list and present the results to the user.

My objective is to have the results displayed automatically once the user finishes typing, without the need for clicking a button.

I believe that a mix of the text_changed event and onkeydown javascript could help achieve this functionality.

I would appreciate any suggestions or thoughts on this matter.

By the way, it's worth mentioning that the sharepoint site I'm working with is "Ajax-enabled".

Thank you!

Answer №1

If you're looking for a solution, I recommend utilizing jquery and the keyup event:

$("input#txtid").keyup(function () {
                if (this.value.length < 8)
                    return false;

                $.get("ServiceUrl", { arg: this.value }, function (result) { $("#output").html(result); });

            });

One of the simplest methods to manage the UI aspect is by employing the AjaxToolkit AutoCompleteExtender set up Optimizing Your Website Using AutoCompleteExtender. After implementing this, the only task left is determining the search process within the web service.

Answer №3

To tackle this task, I implemented the use of an UpdatePanel within my webpart. Added within the UpdatePanel were a Button (more details on this later) and a TextBox.

In addition, I incorporated a JavaScript class responsible for managing the logic behind submitting a query once the user had paused while typing their query. This class included an event handler for the onkeyup event, which was linked to the TextBox:

t.Attributes.Add("onkeyup", "javascript:oSearchClass.KeyUpEventHandler(event);");

I leveraged the functionalities of setTimeout and clearTimeout to dictate when the class should invoke the SubmitQuery function.

Upon calling SubmitQuery(), the TextBox would transition into read-only mode (preventing users from making any further inputs during the querying process) before simulating a click action on the button through click(). By utilizing a standard Button, the Button.click event could be managed like usual in order to re-query the list and exhibit the outcomes.

If showcasing the button to users is not desirable, it can be encapsulated within a hidden WebControl such as span.
