How to show content of two rad editors in a radwindow on button click

Hi,

I want to show content of two rad editors (both are on the same page) in a radwindow (on same page) on a button click using javascript.
Can you please help me in this regard?

A code sample will be a great help.

Also when I am showing content of a control in radwinow. It is working fine on first click (showing correct content). When I close the rad window and again click on the same button, it opens the rad window but this time it comes blank. No content is shown in radwindow.

Can you please help me in this.

printing from within an ajax panel causes javascript error

Hello,

I have a radrid with one column setup for printing the object associated with the ID of the row. Works great unless I ajaxify the grid either wrapping with an AJAX panel or using an ajax manager on the page then I get a javascript error on postback wchihc makes sense because the ajax manager or panel will be trying to interpret the response. How to I bypass the ajax panel for this one behaviour and have the browser rather than the ajax manager respond to the new contect header information?

protected void radGridAll_ItemCommand(Object sender, GridCommandEventArgs e)

{

if (e.CommandName != "Print" ) return;

Guid id = Guid.Parse(e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["ID"].ToString());

//lblMessage.Text = string.Empty;

switch (e.CommandName)

{

case "Print":

//string args = Request.QueryString["ApplicationID"];

NMotionServer.ApplicationLead _application = NMotionServer.ApplicationLeadService.GetByID(id);

if (_application.LeadStatusID == (int)enumLeadStatus.Fresh || _application.LeadStatusID == (int)enumLeadStatus.Viewed)

{

AppHistory _leadStatusEvent = new AppHistory() { ApplicationLeadID = _application.ID, EventTypeID = 2, ForeignKeyID = (int)enumLeadStatus.Printed, Timestamp = DateTime.Now, UserProfileID = ((UserProfile)Session["_userProfile"]).ID };

AppHistoryService.Save(_leadStatusEvent);

_application.LeadStatusID = (int)enumLeadStatus.Printed;

ApplicationLeadService.Save(_application);

}

//RptApplication _applicationReport = new RptApplication((DealerLinkServer.SalesForceWebReference.SforceService)Session["SalesForceBinding"], args);

RptApplication _applicationReport = new RptApplication(id.ToString());

ReportProcessor _processor = new ReportProcessor();

RenderingResult result = _processor.RenderReport("PDF", _applicationReport, null);

string fileName = "NMotion_Lead_" + _application.ApplicantNameLast2First.Replace(" ", "_").Replace(",","_").Replace("'", "_") + "_" + _application.DateOfApplication.Year + _application.DateOfApplication.Month + _application.DateOfApplication.Day + ".pdf";

Response.Clear();

Response.ContentType = result.MimeType;

Response.Cache.SetCacheability(HttpCacheability.Private);

Response.Expires = -1;

Response.Buffer = true;

Response.AddHeader("Content-Disposition", string.Format("{0};FileName=\"{1}\"", "attachment", fileName));

Response.BinaryWrite(result.DocumentBytes);

Response.End();

break;

}

Thanks

RadToolTipManager Basic Start

Hi all,

I am using RadToolTipManager but it is not working on my page. I set html tips on the page, and call the RadToolTipManager control in the page as follows:

<telerik:RadFormDecorator ID="RadFormDecorator1" runat="server" DecoratedControls="All" />
<telerik:RadToolTipManager ID="RadToolTipManager_Tasks"
runat="server"
Animation="FlyIn" />

But nothing is happening, when I was expecting to see the tooltips flying.

Does RadToolTipManager needs the RadFormDecorator control?

Any thoughts?

Thanks,
Bruno

Session Timeout - Continue button not working 2nd time

For testing purposes I have my session timeout set to 3 minutes. 2 minutes before session timeout the popup will appear. If I click "Continue" it stays on the page and hides the dialog. A minute later it will popup again as expected, but this time clicking the "Continue" button doesn't work at all.

I am not getting any javascript errors. If I put an alert in the ContinueSession method I get there after the first click, but not after the second click.

Javascript Code:

<script language="javascript">

//a flag to ease the logic which determines whether to redirect the user

//will not redirect if the RadButton is clicked

var toRedirect = true;

function OnClientHiding(sender, args) {

if (toRedirect) {

window.location.href = sender.get_value();

}

function ContinueSession() {

var notification = $find("<%= rnSessionTimeout.ClientID %>");

toRedirect = false;

notification.update();

notification.hide();

}

function OnClientShowing() {

//raise the flaga again so that a redirect will occur if the notification autocloses

toRedirect = true;

}

</script>

HTML Code:

<telerik:RadNotification ID="rnSessionTimeout" runat="server" Position="Center" Width="300"

Height="125" LoadContentOn="PageLoad" AutoCloseDelay="105000"

Title="Session Expiration" TitleIcon="Warning" OnClientShowing="OnClientShowing"

ContentIcon="Warning" Skin="Default" EnableRoundedCorners="true" OnClientHiding="OnClientHiding">

<ContentTemplate>

<p align="left">

Your session is about to expire. Do you wish to continue using this site?<br />

<telerik:RadButton Skin="Default" ID="continueSession" runat="server" Text="Continue Your Session" Style="margin-top: 10px;" OnClientClicked="ContinueSession" Autopostback="false" />

</p>

</ContentTemplate>

</telerik:RadNotification>

Code Behind:

Protected Sub rnSessionTimeout_CallbackUpdate(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadNotificationEventArgs) Handles rnSessionTimeout.CallbackUpdate

End Sub

How to set LoadingStatusPosition for RadTreeView from client side

Hi,
Could anyone please tell if it is possible to set the LoadingStatusPosition of a RadTreeView from client-side (using javascript)?

We want to keep the LoadingStatusPosition as 'BeforeNodeText' but in one case, we do not want it to show the loading on node expand and we want to achieve this on ClientContextMenuItemClicked (i.e. expand a node on OnClientContextMenuItemClicked with LoadingStatusPosition as none) .

Thanks & Regards,
Puneet

RadMenu stretch menu items

Hello,

I am trying to implement the solution found on the following page:

http://www.telerik.com/support/kb/aspnet-ajax/menu/how-to-stretch-the-menu-items-to-fill-the-entire-width-of-the-menu.aspx

However, I am having problems accessing the RadMenu control client side using the following line

var menu = $find("<%= RadMenu1.ClientID %>");

Please can someone let me know why I struggle to access Telerik controls using this type of javascript command?

Also, does the code in the article above still in work in Q2 2011?

Full code for my solution is below:

<%@ Page Title="Home Page" Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

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

<head>

<title></title>

</head>

<body onload="pageLoad()">

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

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

EnableTheming="True">

</telerik:RadScriptManager>

<telerik:RadMenu ID="RadMenu1" runat="server">

</telerik:RadMenu>

</form>

</body>

<script type="text/javascript">

function pageLoad() {

var menu = $find("<%= RadMenu1.ClientID %>");

Change rdDragHelper

Hello,

I'd really like to change the image used while dragging a collapsed dock around.
I found the rdDragHelper selector in the help files..but nothing I've tried seems to change what/how the image behind the cursor is while dragging.

.rdDragHelper

{

opacity: .1 !important;

filter:alpha(opacity=10) !important; /* For IE8 and earlier */

}

Am I missing a selector..is this not configurable?

Thanks for your input.

RadAjaxLoadingPanel Loading Image not displayed for user controls

Hello

I've run into a strange issue with the RadAjaxLoadingPanel, whereby the panel appears correctly, but not the default loading icon.

I have basically created a version of the Wizard example in the Telerik demos:

http://demos.telerik.com/aspnet-ajax/tabstrip/examples/applicationscenarios/wizard/defaultcs.aspx

This issue also appears in this demo - whenever you are moving between the steps of the wizard, the loading panel does appear (the interface becomes faint), but no loading image.

Is this to do with that fact that the user controls are dynamically loaded, and/or the fact that IsSticky is set to true?

If I specify my own loading image, it does appear, though not in the centre of the loading panel where I would like it to be.

For the rest of my web app (not part of the wizard) I use the default loading image which works perfectly, so I was hoping to use the same for the wizard for consistency.

Any help would be greatly appreciated!
