RadAutoCompleteBox Loading/Spinning Image Not Showing

[kp]

I've a RadAutoCompleteBox bound to a SQL data Source. When I type a text into the box, I want to have the loader/spinner show at the end as shown in this sample:

http://demos.telerik.com/aspnet-ajax/autocompletebox/examples/default/defaultcs.aspx

I've tried using the sample code which is extremely basic, but it still doesn't show the circular image at the end. Please help.

<telerik:RadScriptManager runat="server" ID="RadScriptManager1" />
<telerik:RadAjaxPanel runat="server" ID="RadAjaxPanel1">
        <telerik:RadAutoCompleteBox ID="RadAutoCompleteBox1" runat="server" Width="250" DropDownHeight="150"
            DropDownWidth="250">
        </telerik:RadAutoCompleteBox>
    </telerik:RadAjaxPanel>


protected void Page_Load(object sender, EventArgs e)
        {
            RadAutoCompleteBox1.DataSource = new List<string>() { "Europe", "America", "Asia", "Africa", "Australia" };
        }

Hi Kp,

The loading image of RadAutoCompleteBox will show only if it take time to load the items. In your scenario there is not that much items so it will show the loading image for a very small period of time. Please add the following C# code and check it will show the loader image for sometimes. 

C#:

protected void Page_Load(object sender, EventArgs e)
{
    Thread.Sleep(1000);
    RadAutoCompleteBox1.DataSource = new List<string>() { "Europe", "America", "Asia", "Africa", "Australia" };
}

Thanks,
Princy.

Thanks for the reply Princy but my original connection to sql database takes some time so that's why the need for the image in the first place. I did try to add Thread.Sleep in the above example as suggested, but it still didn't work. I tried increasing the sleep time to 5 seconds but still no luck.

Hi kp,

Unfortunately I couldn't replicate the issue at my end.

Hi Princy, can you please tell me which version of Telerik library you're using? I'm wondering if that's the issue. My version is 2013.3.114.40

Thanks,

Hi kp,

I am able to replicate the issue in telerik version Q3 2013, I tried with the latest version and it is working fine at my end. As a suggestion you can upgrate the telerik version to Q1 2014.

Thanks,
Princy.
