Questions on UI for ASP.NET AJAX Forum

Hi, I've been using the Telerik controls on my personal site as an opportunity to use them, but I'm finding it very difficult to get the AJAX working.
The error which I observed in Firebug is:
uncaught exception: [Exception... "'Sys.WebForms.PageRequestManagerParserErrorException: 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 '

<!DOCTYPE html P'.' when calling method: [nsIDOMEventListener::handleEvent]" nsresult: "0x8057001c (NS_ERROR_XPC_JS_THREW_JS_OBJECT)" location: "JS frame :: chrome://firebug/content/spy.js :: callPageHandler :: line 744" data: no]

Line 0

The code is:

using System;

using System.Web.UI;

using Telerik.Web.UI;

using System.IO;

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

{

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

AddTab("Home", "Home");

AddPageView(DaveRadTabStrip.FindTabByText("Home"));

AddTab("Apps","Applications Created by Dave");

AddTab("Blog","Blog");

AddTab("Contact","Contact Dave");

}

/* Using jQuery's document.ready method would only attach the fancybox when the page first loads,

* which is too early because the content in the RadMultiPage control has not loaded yet and will not

* work on the other tabs because the content is being loaded using AJAX, so the javascript call

* at the top of the page does not attach itself to those newly loaded elements.

*

* The piece of javascript needs to be called on each ajax request so it sets up the fancybox on

* those links. (That is why it is not included in the "if" statement above). To do that, modify the ResponseScripts collection of the RadAjaxManager in your

* AddPageView method:

*/

RadAjaxManager manager = RadAjaxManager.GetCurrent(Page);

manager.ResponseScripts.Add("$(\"a.lib\").fancybox({ 'transitionIdn': 'fade','transitionOut': 'fade' });");

}

private void AddTab(string tabName, string tabText)

{

RadTab tab = new RadTab();

tab.Text = tabText;

tab.Value = tabName;

this.DaveRadTabStrip.Tabs.Add(tab);

}

protected void DaveRadMultiPage_PageViewCreated(object sender, RadMultiPageEventArgs e)

{

string userControlName = @"~/UserControls/" + e.PageView.ID + ".ascx";

Control userControl = Page.LoadControl(userControlName);

userControl.ID = e.PageView.ID + "_userControl";

e.PageView.Controls.Add(userControl);

}

private void AddPageView(RadTab tab)

{

RadPageView pageView = new RadPageView();

pageView.ID = tab.Value;

DaveRadMultiPage.PageViews.Add(pageView);

tab.PageViewID = pageView.ID;

}

protected void DaveRadTabStrip_TabClick(object sender, RadTabStripEventArgs e)

{

AddPageView(e.Tab);

e.Tab.PageView.Selected = true;

}

The code should look pretty familiar as I copied it from one of the Telerik examples. Load on demand (lazy-loading the tabs).
You can observe the behaviour here.

I'd love to know what I'm doing wrong, if anyone can tell me.

Cheers

Weeknumbers incorrect

Hello,

Seems the weeknumbers displayed on the RadDatePicker are not correct.
Today is displayed as weeknumber 21 and its week 20.
The first day of 2011 is in week 52 of 2010 and its not week 1 of 2011.

Its this a bug or can i correct the DatePicker in codebehind?

Remove some scheduler resources from client-side code

Dear Telerik,

Could you please help me with the following issue?

I've got a scheduler with resources and need to remove some of these resources (knowing their types and keys) from the client-side script.

Is it possible?

On the following help page http://www.telerik.com/help/aspnet-ajax/scheduler-schedulerresourcecollection.html

there is a methods remove() which seems to be what I need but I can understand how to use it with a certain scheduler object...

Thank you very much!

- Stepan.

Is there any way so that I can give a space between label and bar?
Also can I increase the Y axis values by code behind by one step?

radgrid -can't remove column from excel export - please help

I want to remove one column for excel export.

I used e.Worksheet.Table.Columns.Remove(3) under ExcelMLExportRowCreated but doesn't work.
I can't make the TagID column invisible on the grid display because I need to use this TagID to check -(!list.Contains(e.Row.Cells.GetCellByName("TagID").Data.DataItem.ToString())) if this TagID exists in the grid. I have to remove it after checking its existing.

-----------------------------------------------------------------------------------

if (!list.Contains(e.Row.Cells.GetCellByName("TagID"

).Data.DataItem.ToString()))

{

if (e.RowType == GridExportExcelMLRowType

.DataRow)

{

Int32

i = e.Worksheet.Table.Rows.Count;

e.Worksheet.Table.Rows.Remove(e.Row);

}

else

{
