RadStyleSheetManager Error when AjaxFrameworkMode="Disabled"

We are trying to create lightweight page and we want combine css and javascript to reduce requests.

But we are not using any Ajax on the page.

Aspx page mark-up:

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

<telerik:RadStyleSheetManager

id="StyleSheetManager"

runat="server" >

<StyleSheets >

<telerik:StyleSheetReference Path="~/Webforms/UI/Mobile/as.mobile.default.theme.min.css" />

<telerik:StyleSheetReference Path="~/Webforms/UI/Mobile/jquery.mobile.structure-1.0.1.min.css" />

</StyleSheets>

</telerik:RadStyleSheetManager>

</head>

<body>

<form id="form1" runat="server">

<telerik:RadScriptManager

ID="ScriptManager"

Runat="Server"

ClientIDMode="Static"

EnableScriptCombine="true"

OutputCompression="AutoDetect"

ScriptMode="Release"

AjaxFrameworkMode="Disabled"

EnablePartialRendering="false"

CompositeScript-ScriptMode="Release"

LoadScriptsBeforeUI="false" >

<CompositeScript>

<Scripts>

<asp:ScriptReference Name="WebForms.js" Assembly="System.Web" />

<asp:ScriptReference Name="WebUIValidation.js" Assembly="System.Web" />

<asp:ScriptReference Name="jQuery" />

</Scripts>

</CompositeScript>

</telerik:RadScriptManager>

</form>

</body>

</html>

So we set AjaxFrameworkMode="Disabled" and added the additional scripts. On load the page give the following error on "Sys.Application.add_load(loadHandler); line":

Uncaught ReferenceError: Sys is not defined

<script type="text/javascript">

//<![CDATA[

;(function() {

function loadHandler() {

var hf = $get('StyleSheetManager_TSSM');

if (!hf._RSSM_init) { hf._RSSM_init = true; hf.value = ''; }

hf.value += ';|634643790138684980:20a54711:5489a487';

Sys.Application.remove_load(loadHandler);

};

Sys.Application.add_load(loadHandler);

})();//]]>

</script>

how can we achieve this.

Thank you

Farid

Not combining scripts

I have to add a radscriptmanager in a base class and I want to combine the script however it doesn't appear to work. I am ensuring that this control is added as the first control of the form. I have the following...

RadScriptManager sm = new RadScriptManager();
   sm.ScriptMode = ScriptMode.Release;
   ScriptReference telerikCore = new ScriptReference("~/Scripts/Common/Core.js");
   ScriptReference jquery = new ScriptReference("~/Scripts/Common/jQuery.js");
   ScriptReference jQueryPlugins = new ScriptReference("~/Scripts/Common/jQueryPlugins.js");
   ScriptReference navigationScripts = new ScriptReference("~/Scripts/Common/Navigation/NavigationScripts.js");
   ScriptReference radMenuScripts = new ScriptReference("~/Scripts/Menu/RadMenuScripts.js");
   ScriptReference radCalendarCommonScript = new ScriptReference("~/Scripts/Calendar/RadCalendarCommonScript.js");
   ScriptReference radCalendarScript = new ScriptReference("~/Scripts/Calendar/RadCalendarScript.js");
   ScriptReference jqueryValidate = new ScriptReference("~/js/jquery.validate.js");
   ScriptReference slimStatAnalytics = new ScriptReference("~/slimstat/?js");
   sm.Scripts.Add(telerikCore);
   sm.Scripts.Add(jquery);
   sm.Scripts.Add(jQueryPlugins);
   sm.Scripts.Add(navigationScripts);
   sm.Scripts.Add(radMenuScripts);
   sm.Scripts.Add(radCalendarCommonScript);
   sm.Scripts.Add(radCalendarScript);
   sm.Scripts.Add(jqueryValidate);
   sm.Scripts.Add(slimStatAnalytics);

   sm.EnableScriptCombine = true;
   sm.EnablePageMethods = true;
   sm.OutputCompression = OutputCompression.AutoDetect;

   form.Controls.AddAt(0, sm);

I get a Telerik.Web.UI.WebResource.axd file containing 10,000 lines of code which looks like Ms Ajax related js - no reference to Telerik in there at all. My page still contains the scripts as separate links. Do I need to set enableembeddedscripts to false on all my rad controls? How about the RegisterWithScriptManager property on radmenu?

If I create another page and do this in mark up it works fine. What am I doing wrong? I don't suppose you have an example of this working?

Thanks
Matt

            RadSiteMap sm = new RadSiteMap();
            PopulateSiteMap(sm, null, item);

            //sitemap settings to have the menu items appear in columns

            foreach (RadMenuItem child in item.Items)
            {
                node.Nodes.Add(new RadSiteMapNode(child.Text, child.NavigateUrl));

Radcombo With Multiple Check Box Selection.

Hi ALL,
I have done multiple check box selection inside the Radcombobox using Javascript Please have one look it may help you in your project:

JAVASCRIPT:

<script type="text/javascript">

function onCheckBoxClickClass(chk, combo) {

var combo;

if (combo == 'rcbClassGroup') {

combo = $find("<%= rcbClassGroup.ClientID %>");

}

cancelDropDownClosing = true;

//holds the text of all checked items

var text = "";

//holds the values of all checked items

var values = "";

//get the collection of all items

var items = combo.get_items();

//enumerate all items

for (var i = 0; i < items.get_count(); i++) {

var item = items.getItem(i);

//get the checkbox element of the current item

var chkMultipleSelectclass = $get(combo.get_id() + "_i" + i + "_chkMultipleSelectclass");

if (chkMultipleSelectclass.checked) {

text += item.get_text() + ",";

values += item.get_value() + ",";

}

//remove the last comma from the string

text = removeLastComma(text);

values = removeLastComma(values);

if (text.length > 0) {

//set the text of the combobox

combo.set_text(text);

}

else {

//all checkboxes are unchecked

//so reset the controls

combo.set_text("");

}

var cancelDropDownClosing = false;

function removeLastComma(str) {

return str.replace(/,$/, "");

}

function StopPropagation(e) {

//cancel bubbling

e.cancelBubble = true;

if (e.stopPropagation) {

e.stopPropagation();

}

function onDropDownClosing() {

cancelDropDownClosing = false;

}

function selectAllNodes(chk, combo, chkItem, ChkNone) {

var combo;

var combobox;

if (combo == 'rcbClassGroup') {

combobox = $find('<%=rcbClassGroup.ClientID %>');

}

var nestedCheckBox = combobox.get_items()._array;

for (var i = 0; i < nestedCheckBox.length; i++) {

var chk1 = $get(combobox.get_id() + "_i" + i + "_" + chkItem);

chk1.checked = chk.checked;

}

if (chk.checked && combo == 'rcbClassGroup')

onCheckBoxClickClass(chk, combo);

if (ChkNone != null) {

var chkNone = $get(combobox.get_id() + "_Header_" + ChkNone);

RadAjaxLoadingPanel in master page

Hi,

is it possible to place a RadAjaxLoadingPanel inside the master page so it will show on any kind of postback event!? I don't want to attach the RadAjaxLoadingPanel to specific controls like a send button which fire the postback. As for me, it should work on any page using the master page. Is this possible!?

Thanks in advance

Initial Grid filter expression on being passed to DataBinding
