For accessibility, I'm trying to add a tabindex attribute to the captcha image.
Here is the script I'm using:
document.addEventListener("DOMContentLoaded", function(){
document.getElementById("ctl00_ContentContainer_EntityFormControl_aeace8755f5aec118f8f000d3a5b28d1_EntityFormControl_aeace8755f5aec118f8f000d3a5b28d1_EntityFormView_captcha_CaptchaImageUP").tabIndex = 0;
alert(‘page loaded successfully’);
});
The script can't seem to find the image tag by the id. What am I missing here?

Hi everyone,
I'm having problems with $find and getElementById. In my page $find doesn't find the objects while getElementById finds them but then the client-side API functions are not executed (error message: "splitter2.get_height is not a function").
$find always returns NULL, both on the RadSplitter and RadGrid.
To understand I also isolated the affected code in a new page, same problem. This is the code:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>
<!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 runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<telerik:RadScriptManager ID="RadScriptManager1" runat="server">
<Scripts>
<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
</Scripts>
</telerik:RadScriptManager>
<div>
<telerik:RadSplitter ID="RadSplitter1" runat="server" SplitBarsSize="2" Width="100%" >
<telerik:RadPane ID="LeftPane" runat="server" >
<telerik:RadGrid ID="RadGrid1" runat="server"></telerik:RadGrid>
</telerik:RadPane>
<telerik:RadPane ID="RightPane" runat="server" >
</telerik:RadPane>
</telerik:RadSplitter>
</div>
<script type="text/javascript">
var Alt = window.innerHeight;
var Larg = window.innerWidth;
var splitter = $find('<%= RadSplitter1.ClientID %>');
alert(splitter);
var grid = $find('<%= RadGrid1.ClientID %>');
alert(grid);
var splitter2 = document.getElementById('<%= RadSplitter1.ClientID %>');
alert(splitter2);
alert(splitter2.get_height());
splitter2.set_height(800);
</script>
</form>
</body>
</html>
Thanks for your help

But on my target project, after deleting a step: Step is deleted. all looks fine. But each time i click on "next" or on another step header i recieve error message.. In errormessage i see this has nothing to do with my code.

What is the event sequence of grid OnPreRender? Will it be fired only once or every time there is a postback?
When the grid is ajaxified, will OnPreRender be fired every time when there is a postback?
I'm asking this because when postback my breakpoint in Grid OnPreRender is not hit after Page_PreRender event when the grid is ajaxified.
Thanks.

Hi,
I am trying to implement form template demo here, https://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/form-template-update/defaultvb.aspx . The problem is that it is throwing error on 'Bind' that it is not declared. I am using .NET 4.6..1 . The only differences are is that with the sqldatasource, it's running stored procedures rather than a query and It's in a radajaxpanel.

The RadMultiSelect implementation has one error that WCAG 4.1.1 parsing is catching. There is a duplicate span with the same id.
Found in the page source of the demo page (similar to how I implemented as well):
https://demos.telerik.com/aspnet-ajax/multiselect/virtualization/defaultcs.aspx
<select name="ctl00$ContentPlaceholder1$RadMultiSelect1" multiple="" id="ctl00_ContentPlaceholder1_RadMultiSelect1" class="RadMultiSelect RadMultiSelect_Silk" style="width:400px;">
<span id="ctl00_ContentPlaceholder1_RadMultiSelect1_WebServiceCDS" style="display:none;"></span><input id="ctl00_ContentPlaceholder1_RadMultiSelect1_ClientState" name="ctl00_ContentPlaceholder1_RadMultiSelect1_ClientState" type="hidden" />
</select><span id='ctl00_ContentPlaceholder1_RadMultiSelect1_WebServiceCDS' style='display:none'></span>

Hi Telerik team,
the "Contrast Security" tool we use shows us a "Untrusted Deserialization" Vulnerability found on one of the ASPX (webForms) page where we utilize RadMultiSelect control. (Our current version is 2021.1.119.45).
Could you please suggest any options now to fix it, please?
Details:
Tracked the following data from "ctl00_Main_content_ddlMSelectMultipleStaff_ClientState...:
POST /vosnet/communications/scheduler/default.aspx
ctl00_Main_content_ddlMSelectMultipleStaff_ClientState={"enabled":true,"selectedItems":[],"deselectedItems":[],"value":[2613],"selectedDataItems":[{"text":"Skaggs","value":"2613","Lastname":"Skaggs","Userid":2613,"attributes":{"FullName":"Skaggs Kari","Color":"background-color:rgb(89,20,195);","ColorARGB":"5838019"}}]}&ctl00$textsize=.......SNIP...........
...which was accessed within the following code:
Telerik.Web.UI.RadMultiSelect.LoadPostData()
...and ended up being deserialized with code that looks like this:
m = serializer.Deserialize<M>("{"enabled":true,"selectedItems":[],"deselectedI...")

Please help.
Hello. I have put a telerik grid inside an asp update panel, the update panel is updated every 5 seconds by a asp timer on the same page. Inside the timer's OnTick event, I wrote RadGrid.Rebind() since the datasource is changing over time.
There is an edit button column for RadGrid, when user presses this button inside this column to edit corresponding record, the input values are always flushed out by RadGrid.Rebind. By the way, the edit mode of grid is in line editing.
In order to handle this issue, I added code inside the timer's OnTick event before RadGrid.Rebind, that is to check if RadGrid.EditItems.Count > 0 then return and don't rebind. Now the input values won't be flushed but the mouse cursor will always be reset.
Is there any possible way to realize my requirement, keep input values in edit mode while the RadGrid is inside an update panel that updates every few seconds?
Thanks!
