How can i fire Cleint-Side events in WebUserCotnrol

[Hakan Tüzün]

Hi,

I'm using RadComboBox in a Web User Control. When I drop the Web UserControl on a page, I can not use Client-Side RadComboBox events such as "OnClientDropDownClosing".

I know that I must handle this event within the UserControl, but how can I triger a custom event for the page then?

With Server-Side events, I do not have problem,

Kind Regards,

Hakan

Hi Hakan,

Please find below a sample code snippet that shows the needed approach.

Default.aspx:

<form runat="server" id="mainForm" method="post">
    <asp:ScriptManager ID="ScriptManager" runat="server" />
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <uc1:WebUserControl ID="WebUserControl1" runat="server" />
</form>

WebUserControl.ascx:

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl.ascx.cs" Inherits="WebUserControl" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<script type="text/javascript">
function ChangeText(sender, eventArgs)
{
    var item = eventArgs.get_item();
    var myTxtBox = $get('<%= ((TextBox)Page.FindControl("TextBox1")).ClientID %>');
    myTxtBox.value = item.get_text();
}
</script>

<telerik:RadComboBox ID="RadComboBox1" runat="server" OnClientSelectedIndexChanged="ChangeText">
    <CollapseAnimation Duration="200" Type="OutQuint" />
    <Items>
        <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem1" Value="RadComboBoxItem1" />
        <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem2" Value="RadComboBoxItem2" />
        <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem3" Value="RadComboBoxItem3" />
        <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem4" Value="RadComboBoxItem4" />
        <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem5" Value="RadComboBoxItem5" />
        <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem6" Value="RadComboBoxItem6" />
    </Items>
</telerik:RadComboBox>

All the best,
