Pb using captcha in a wizard ContentTemplate

Hello,

I get this error when I try to add a radcaptcha inside the template of a createuserwizard
"Cannot unregister UpdatePanel with ID '' since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported"

It seems that captcha is inserting itself automatically in some control collection and create a related updatepanel ?

How to solve this ?

Thank you for help.
CS

PS: seems the updatepanels have no ids ?

RadDataPager page links change re-written urls to original

Hi,
In my page I used to have RadGrid with pagination and SEO enabled.
Everything was working fine, but I needed to have Div layout, I changed it to RadListView and RadDataPager.
Now the only problem that I have is that the pages' links changes the re-written urls to the original one.
For example:
Re-written Url: http://www.mysite.com/car/123
Original Url: http://www.mysite.com/cars.aspx?carId=123

I expect for page 2 the link would be:
http://www.mysite.com/cars/123?pageno=2

But the link is changed back to the original and is like this:
http://www.mysite.com/cars.aspx?carId=123&pageno=2

I did not have such a problem with RagGrid Pagination.
By the way, I am using Telerik controls of DotNetNuke. The version is 2010.1.309.35.

Thanks.

TimeSlotCreating is not fired before Page_Load on post back.

I am running into an issue where my RadScheduler's TimeSlotCreated event gets fired BEFORE my Page_Load function on a postback, where my logic in Page_Load() needs to run before the TimeSlotCreated event gets fired off.

I saw in some past patch notes for Q2 2008 SP1 (version 2008.2.826) HERE one of the fix notes under RadScheduler:
- TimeSlotCreating is not fired before Page_Load on post back.

I am currently developing with ASP.NET AJAX Q3 2009, and am still seeing TimeSlotCreated event getting called before my Page_Load

Something I am doing wrong? Or is the bug still in the version I am using?

[Solved] how to client click event for button used in RadAjaxManager

hi,
I have asp.net LinkButton, where it has been configured with RadAjaxManager to update asp.net panel.
now I wanna after the update done (the content of that panel changed) I need to call a javascript function, because in this new content, there is div which making a type of sliding effect, but it will not start the effect unless the javascript function is called, so I need to call that javascript function once the update of asp.net panel is done.

I tried to add "OnClientClick" property to LinkButton, but that does not working, and even it did not triggered!

and I have tried to create another panel and in ajax calling, I tried to fill it with a Literal control, where this literal:
Literal l = new Literal();
l.Text = "<script type='text/javascript'>coda_side_it();</script>";

but this is not working, and moreover, I tried to Response.Write("<script type='text/javascript'>coda_side_it();</script>"); but that makes a big problem with ajax!!

so please any help?

}

Well, the ItemCommand event is not firing, even when "btnExcluir" (the ImageButton) is clicked. What am I doing wrong?

Thanks in advance!

Select Value from GridDropDownColumn

I hope this is an easy question to answer. I have a RadGrid with various bound columns, one of which is a GridDropDownColumn. I'm binding the column declaritively to a SQLDataSource as follows:

GridDropDownColumn:

<telerik:RadGrid runat="server" ID="rgUserMapping" AutoGenerateColumns="false" AllowPaging="true" PageSize="20">

...

<%-- MasterTableView Settings --%>

<MasterTableView AllowSorting="true" Caption="" Summary="" AllowFilteringByColumn="true" ItemStyle-VerticalAlign="Top" DataKeyNames="UserMappingID" CommandItemDisplay="Bottom" EditMode="PopUp">

...

<%-- Columns --%>

<Columns>

...

<telerik:GridDropDownColumn DataField="Component" HeaderText="Component" FilterControlWidth="50" AutoPostBackOnFilter="true" CurrentFilterFunction="Contains" DataSourceID="dsComponentDataSource" ListTextField="Title" ListValueField="ID" DropDownControlType="RadComboBox" />

...

</Columns>

</MasterTableView>

</telerik:RadGrid>

When the RadGrid loads, I get what looks like text in the place of the GridDropDownColumn, and the text is what would be the first item in the bound dropdownlist.

I want the text to read the actual value that comes from the database. How do I make that happen?

How to scroll (vertically ) when using WebService/oData/ADO.NET DataServices?

I'm using the Grid with oData (aka ADO Data Services http://www.telerik.com/help/aspnet-ajax/grdclientbindingtowcfserviceadonetdataservice.html) and am unable to get the grid to scroll with a vertical scrollbar.

How do I make this happen? It seems that the page size is fixed and won't allow me to render anything outside of a default page boundary.

Also, I'd like to programmaticly navigate to a specific row, on a different page, using javascript.
