Changing the background colour of the selected item

Hi

I have been reading this thread:http://www.telerik.com/community/forums/aspnet-ajax/combobox/combo-box-color-picker.aspx

As I want to change the background colour of the selected item when an item in my dropdown is selected.
It gives this bit of javascript to do the job, but it's obviously very old as no longer works in the same way.

function onClientSelectedIndexChanged(item)

{

var combo = item.ComboBox;

var comboInput = document.getElementById(combo.InputID);

//here ItemColor is a custom attribute that you can assign in ItemDatabound event

comboInput.style.backgroundColor = item.Attributes.ItemColor;

}

</script>

I have changed it to:

function onClientSelectedIndexChanged(sender, eventArgs) {

var combo = eventArgs.get_item();

var comboInput = document.getElementById(combo.InputID);

//here ItemColor is a custom attribute that you can assign in ItemDatabound event

comboInput.style.backgroundColor = item.Attributes.ItemColor;

}

but the "document.getElementById(combo.InputID); " does not work, as i expected it wouldn't but I don't know what the replacement if it is?

Can anyone help?

NoRecordsTemplate causes Sys.WebForms.PageRequestManagerParserErrorException error

Hello, I have RadGrid uses NoRecordsTemplate, but this template contains server tags as the following:

<

NoRecordsTemplate>

<center>

<iframe src='<%= GetTrainingVideo("RiskManagement.Options") %>' class="EmbededVimeo"

width="400" height="300" frameborder="0">

</iframe

</center>

</NoRecordsTemplate>

if there is no data at page load the template works fine, but when delete the last record the grid rebind itself and generate the following JS error:

Error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

Details: Error parsing near 'hidden" />

</div>

|0|updatePanel|ctl0'.

This issue just appear when host the application under secure protocol (HTTPS),

I've tried to create the content of NoRecordsTemplate server side at the following event handlers: OnItemCreated and OnPreRender, but the issue still exist.

Do you have resolution for this issue?

Editing Unbound Checkbox in RadGrid

Is it possible to edit unbound checkbox in a radgrid? my experience is telling me no, but perhaps there is trick i could use to do so.

i have a grid bound to a sqldatasource. the data source includes a dummy column cast as a bit to default true. the check box displays checked (as expected) but whenever i enter edit mode, uncheck the box, then click update, the check box reverts to checked because - i surmise - that it is rebinding to the dummy bit column which is set to 1/true.

it is this surmised behavior which i wish to override. is it possibe? if not, would you consider adding a feature to allow for a free standing unbound check box so that developers can present a toggle for subsequent processing of grid items? i do not care to save this information to a data store - i only need it to process selected grid items.

Problem with DefaultButton in Q1 2012

Hi to all,
I have upgraded my telerik controls from 2011.2.915.40 to 2012.1.215.40 with msi installer.
After uprade I discovered that defaultbutton declared for asp:Panel does not fire postback on pressing
the key Enter.
Here is small example. It works fine with older Telerik.Web.UI, but not with Q1 2012.

<%@ Page Language="C#" AutoEventWireup="True" CodeBehind="Default.aspx.cs" Inherits="Test._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>Test</title>

</head>

<body>

<form id="MainForm" runat="server">

<telerik:RadScriptManager ID="RadSCM" runat="server" />

<asp:Panel ID="pnlWrapper" runat="server" DefaultButton="btnSearch">

<telerik:RadTextBox ID="tbSearch" runat="server" EmptyMessage="Search" Width="130" />

<telerik:RadButton ID="btnSearch" ButtonType="StandardButton" Text="Search" ToolTip="Searching" runat="server" OnClick="btnSearch_Click" />

</asp:Panel>

<asp:Label ID="lblMsg" runat="server" />

</form>

</body>

</html>

using System;

namespace Test

{

public partial class _Default : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

lblMsg.Text = string.Empty;

}

protected void btnSearch_Click(object sender, EventArgs e)

{

lblMsg.Text = "O.K. - Button fired";

}

Does anybody know where is the problem?
Thanks
-Marian

RadGrid AddNewRecordButton problem on Prerender event

Hi,
I am using RadGrid from telerik version 2012.1.215.40.

I have two methods RadGrid_NeedDataSource and Page_Prerender event

I am trying to hide AddNewrecordButton based on user permissions

protected override void OnPreRender(EventArgs e)

{

try

{

//Hide controls on the page based on permission

//Code to hide control

// code to hide RadGrid AddNewRecordButton

RadGrid1.MasterTableView.CommandItemSettings.ShowAddNewRecordButton = false;

}

base.OnPreRender(e);

}

catch (Exception ex)

{

HandleException(ex, ErrorControl);

}

This code doesn't hide the AddNewRecordButton from the grid.
But if i write the same code in RadGrid_NeedsdataSource event, it works. I also tried radGrid_PreRender event but that also not working.
If i add RadGrid.Rebind() method in prerender event, it works. But it fires the NeedsdataSource event again that i don't want.
All my code to hide/show controls based on the permissions is inside the PreRender event. So i don't want to use NeedsDataSource event just for hide/show of Add new record button.
Please suggest what is wrong with the PreRender event.
