Page is being refreshed when OnEntryAdded callback function is triggered...

[Yan Moura]

I am using AutoCompleteBox in an ASPX page with VB in code behind. I have a callback function 'OnEntryAdded' and every time this function is triggered my page is being refreshed. What am I doing wrong?

This is my ASPX code:

<form id="form1" runat="server">
<telerik:RadScriptManager runat="server" ID="RadScriptManager1" />
<telerik:RadAutoCompleteBox
    RenderMode="Lightweight"
    runat="server"
    ID="RadAutoCompleteBox1"
    autopostback="true" EmptyMessage="Type in data..."
    DataSourceID="SqlDataSource1"
    DataTextField="edesc"
    DataValueField="ecode"
    InputType="Token"
    Width="100%"
    DropDownWidth="150px"
    OnEntryAdded="RadAutoCompleteBox1_EntryAdded"
    >
</telerik:RadAutoCompleteBox>

<asp:SqlDataSource runat="server"
    ID="SqlDataSource1"
    CancelSelectOnNullParameter="False"
    ConnectionString="<%$ AppSettings:MyConn %>"
    SelectCommand="exec dbo.myquery">
</asp:SqlDataSource>
</form>

This is my code behind

Imports System.Diagnostics
Imports Telerik.Web.UI
Imports System.Data.SqlClient

Partial Class custom_scripts_blah
    Inherits System.Web.UI.Page

    Protected Sub RadAutoCompleteBox1_EntryAdded(sender As Object, e As Telerik.Web.UI.AutoCompleteEntryEventArgs)
    End Sub

End Class

 

 

Any idea?

Hello Yan,

The OnEntryAdded event is a server-side event that requires a postback. 

• https://docs.telerik.com/devtools/aspnet-ajax/controls/autocompletebox/server-side-programming/events/onentryadded 

The Callback is used only for populating the data when the dropdown is shown while filtering and choosing items.

You can wrap the control in an AjaxPanel/asp:UpdatePanel or add it as an UpdatedControl in the AjaxSettings of the RadAjaxManager which will update only the AutoCompleteControl when the OnEntryAdded is fired, instead of refreshing the whole page.

Thank you Peter. It was my bad. Ajax wasn't active. It's solved now.
