JavaScript runtime error : '$telerik' is undefined

We have just started using UI for ASP.NET AJAX. Everything works fine until we try using client-side code. We keep receiving this error : "JavaScript runtime error : '$telerik' is undefined". I've searched for a solution online but none of the suggested solutions works.

At the moment our web.config has the following entries which according to online sources would solve the problem but didn't :

We also tried the following to no avail :

<system.webServer>
<handlers>
<add name="Telerik_Web_UI_WebResource_axd" verb="*" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" preCondition="integratedMode" />
</handlers>
</system.webServer>

In default.aspx we have the following :

<telerik:RadScriptManager ID="scriptManagerMain" 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>
<Services>
<asp:ServiceReference Path="~/WCF/DataService.svc"/>
</Services>
</telerik:RadScriptManager>
<telerik:RadAjaxManager ID="radAjaxManagerMain" runat="server">
</telerik:RadAjaxManager>

With all these settings we still keep receiving the "JavaScript runtime error : '$telerik' is undefined" error. I really hope someone knows the solution to this problem because we're stick here and can't find a solution. Thanks in advance for any help.

Exception: 'System.OutOfMemoryException' was thrown when there is 5000+ data need to be bind in RadComboBox inside RadGrid

I have a RadGrid and a RadComboBox outside of RadGrid (say comboOutside), inside a Web Form.
Inside RadGrid, there is 1 more RadComboBox (say comboRadGrid). On selection of items from comboOutside, comboRadGrid is bind i.e., If item 'Company' is selected from comboOutside, then all the company names will be bind in comboRadGrid; and then user select specific company from comboRadGrid and records are added in RadGrid.

For all items, functionality is working fine but I am facing issue in binding of a specific comboOutside item. i.e., When I choose a specific item from comboOutside, say I have 100 items inside comboOutside, and when I select 35th items from it, then comboRadGrid always throw this error while binding records for 35th item (since 35th item has 2000+ records to bind in comboRadGrid)
Error is attached below:
Funcitonality is working fine for all the items except 1 specific item of RadComboBox. I don't understand why. Due to this I am unable to add records in RadGrid
Below is my code-

C# code

public DataTable GetAccCode(string CompanyCode)

    {

        SqlConnection con = new SqlConnection(strcon);

        SqlCommand cmd = new SqlCommand("[Invoice].[usp_tbl_AccountCode_DL_Test]", con);

What browsers are supported for copying and pasting images into RadEditor as Base64 images. I know that for IE only IE 11 is supported but what about for Chrome or Firefox? What are the minimum versions.

Any help is appreciated. Thanks!

How to fire server event when clicking checkbox

Hi,

I have listview that works well with the definition below:

<telerik:RadListView ID="lvwUserGroups" runat="server" ItemPlaceholderID="groupsPlaceholder" OnNeedDataSource="lvwUserGroups_NeedDataSource"

DataKeyNames="GroupID" >

<LayoutTemplate>

<div class="RadListView RadListView_<%# Master.SkinManager.Skin %>" >

<table class="mainTable">

<thead>

<tr class="rlvHeader">

<th class="thcenter">Enabled</th>

<th>Group</th>

</tr>

</thead>

<tbody>

<asp:PlaceHolder id="groupsPlaceholder" runat="server">

</asp:PlaceHolder>

</tbody>

</table>

</div>

</LayoutTemplate>

</telerik:RadListView>

protected class userGRPTemplate : ITemplate

{

private ADScrubWeb.HTMLHelper helper = new ADScrubWeb.HTMLHelper();

public userGRPTemplate()

{

}

public void InstantiateIn(Control container)

{

TableRow tr = new TableRow();

container.Controls.Add(tr);

helper.AddControlToParent(container, helper.AddBoundHiddenField("GroupID"));

helper.AddControlToParent(tr, helper.AddBoundCheckBox("Enabled"), true, HorizontalAlign.Center);

helper.AddControlToParent(tr, helper.AddBoundTextBox("GroupName", BorderStyle.None, true), true, HorizontalAlign.Left);

}

public CheckBox AddBoundCheckBox(string controlID)

{

CheckBox tmp = new CheckBox();

tmp.ID = controlID;

tmp.DataBinding += delegate(object sender, EventArgs args)

{

CheckBox control = ((CheckBox)sender);

RadListViewDataItem listViewDataItem = ((RadListViewDataItem)control.NamingContainer);

control.Checked = lsuGeneral.IsTrue(DataBinder.Eval(listViewDataItem.DataItem, controlID).ToString());

};

return tmp;

}

I would like to react to the user clicking the bound checkbox so I can do auto-updates without the user clicking an update button. I tried wiring up the checkbox CheckedChange event in the ITemplate but that didn't fire, anyway I would still need to know which row's checkbox was clicked.

Any ideas?

ImageEditor "Closing" event ?!

Hi,

I have a couple of questions:

1. Is there a way to know when the ImageEditor is being closed by the user? i.e. when the user is clicking the cancel button or the X button?

2. When the ImageEditor is "closed", the underlying object is not yet disposed, is there a property of the object that can be used to check if it is closed ?

Thanks
Elie

We are using version 2014.1.403.35

RadScriptManager error in sharepoint visual web part

Hi everyone,

I am trying to use RadAutoCompleteBox in a Sharepoint Visual Web Part solution, so i use below code which is working in another asp.net web application.

<telerik:RadScriptManager ID="RadScriptManager1" runat="server"></telerik:RadScriptManager>

<telerik:RadAutoCompleteBox runat="server" ID="RadAutoCompleteBox1" EmptyMessage="Please search name here" Delimiter=","
DataSourceID="SqlDataSource1" DataTextField="StaffName" InputType="Text" Width="250px" DropDownWidth="240px" Style="float: left; height: 22px">
<TextSettings SelectionMode="Single" />
</telerik:RadAutoCompleteBox>

<asp:SqlDataSource runat="server" ID="SqlDataSource1" ConnectionString="Data Source=CNDEVSQL1;Initial Catalog=SAVLEAVE_OFFLINE;Integrated Security=True"
ProviderName="System.Data.SqlClient" SelectCommand="SELECT [StaffName] FROM [SAVLEAVE_OFFLINE].[dbo].[Staffs]"></asp:SqlDataSource>

i found that if my aspx for sharepoint contains RadScriptManager , then this page will return yellow page.

while the other radcontrol is working if there is no RadScriptManager in aspx.

i also added correct web config in my sharepoint site.

<SafeControl Assembly="Telerik.Web.UI, Version=2014.2.812.45, Culture=neutral, PublicKeyToken=121fae78165ba3d4" Namespace="Telerik.Web.UI" TypeName="*" Safe="True" />
<SafeControl Assembly="Telerik.Web.Design, Version=2014.2.812.45, Culture=neutral, PublicKeyToken=121fae78165ba3d4" Namespace="Telerik.Web.Design" TypeName="*" Safe="True" />
<SafeControl Assembly="Telerik.Web.UI.Skins, Version=2014.2.812.45, Culture=neutral, PublicKeyToken=121fae78165ba3d4" Namespace="Telerik.Web.UI.Skins" TypeName="*" Safe="True" />

<httpHandlers>
<add path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" validate="false"/>
<add path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" validate="false"/>
<add path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false"/>
<add path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" validate="false"/>
<add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false"/>
</httpHandlers>

i also registered telerik dll in visual studio command prompt.

gacutil -i c:\Telerik\Telerik.Web.UI.dll

gacutil -i c:\Telerik\Telerik.Web.Design.dll

i think this is some issue of RadScriptManager for sharepoint? because radajax panel ,radgrid is working correctly in the same page if there is no RadScriptManager .

any help is much appreiated because this issue is troubling me for many days!!

How to Add radconfirm confirmation when user presses delete key to delete a row in radgrid

Hi

The users can delete rows in a radgrid by pressing the delete key from the keyboard. But there is no confirmation pop up to prevent the user from deleting the row by mistake. When users presses the delete key i use fireCommand("Cancel", "") to prevent the row from deleting. After that i want to display a radconfirm window but the radconfirm window pops up for a second only and goes away without allowing the user to press either Yes or No. How can I stop the radconfirm window from closing?

case 46: //Delete

            if (!(event.srcElement.type == "text") && !(event.srcElement.type == "textarea")) {
                GetGrid().get_masterTableView().fireCommand("Cancel", "");
                radconfirm(prompt, clientCallBackFunc);
            }
            break;

Thanks
Muhammad

Sort gantt chart by standard column

Hello,

is it somehow possible to sort the tasks e.g. by start date. It seems that it's only possible to sort the tasks inside the gantt by custom columns when using a custom gantt provider. Sorting by a standard column like title or start date is ignored. Thanks.

Regards,

Scheduler and Exchange

Hi,

I need to synchronize the RadScheduler with the Exchange server account using Exchange Web Services. I used the RadScheduler SDK uploaded on the official web site :

http://docs.telerik.com/devtools/aspnet-ajax/controls/scheduler/data-binding/providers/exchange-provider

An error was generated on SharePoint Side: System.Net.WebException: The remote name could not be resolved: (DomainName) knowing that the exchange web service is runing properly.

I use SharePoint 2010 and Telerik.Web.UI, Version=2015.1.401.35

Thank you for your support.
