Howdy, y'all. I'm sure I'm missing something really basic, here. I'm trying to write some additional information to the client-side attributes for a raddateinput control. (This is part of a larger project, writing a custom validator, etc). I've simplified out to a basic web page illustrating my challenge. Here's my ASPX:
| <%@ Page Title="" Language="C#" AutoEventWireup="true" CodeBehind="test5.aspx.cs" Inherits="TASDashboard.Secured.test5" %> |
| <%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %> |
| <%@ Register assembly="Controls" namespace="TASDashboard" tagprefix="cc1" %> |
| <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> |
| <html xmlns="http://www.w3.org/1999/xhtml"> |
| <head id="Head1" runat="server"> |
| <title>Untitled Page</title> |
| </head> |
| <body> |
| <form runat="server"> |
| <script language="javascript" type="text/javascript"> |
| function testFunction(sender, args) { |
| alert(sender.testAttribute); //shows as undefined |
| } |
| </script> |
| <telerik:RadScriptManager ID="RadScriptManager1" runat="server"> |
| </telerik:RadScriptManager> |
| <telerik:RadDateInput ID="RadDateInput1" Runat="server" DateFormat="HHmm" |
| Skin="Office2007"> |
| </telerik:RadDateInput> |
| <asp:ValidationSummary ID="ValidationSummary1" runat="server" /> |
| <p> |
| <asp:Button ID="Button1" runat="server" Text="Button" /> |
| </p> |
| </form> |
| </body> |
| </html> |
and here's my C#:
| using System; |
| using System.Collections.Generic; |
| using System.Linq; |
| using System.Web; |
| using System.Web.UI; |
| using System.Web.UI.WebControls; |
| namespace TASDashboard.Secured |
| { |
| public partial class test5 : DashboardBasePage |
| { |
| protected void Page_Load(object sender, EventArgs e) |
| { |
| RadDateInput1.ClientEvents.OnValueChanged = "testFunction"; |
| RadDateInput1.Attributes.Add("testAttribute", "hello"); |
| } |
| } |
| } |
And when I run it, and change the value of the raddateinput control, my javascript routine runs as expected, but sender.testAttribute is undefined. Should I be looking somewhere else for testAttribute?
Thank you!

Hello Scott,
Generally sender is the instance of the JavaScript object - you can try sender.get_element() instead!

Vlad -
Thank you. That was ALMOST it. (I'd forgotten how useful the IE Developer toolbar can be in times like this.) Just for anyone else reading this later - it looks like there are three INPUT elements within a span, for each RadDateInput:
RadDateInput1_text
RadDateInput1
RadDateInput1_ClientState
get_element() gets me RadDateInput1, but the attribute was on the _text. So my final javascript that goes with the example I posted is:
Thanks again,
Scott
