this one took me some time to figure out, but I am at a loss to understand what is happening.
I created the following class:
The purpose of this is to use methods in the page instance as data source for controls (in this case a RadGrid). This caused the web resource to stop loading, causing datepickers, timepickers etc to stop working (and the dreaded "Sys is not defined" and "Telerik" is not defined" javascript errors).
Can anyone spot what I may have violated to cause this behaviour?
I created the following class:
| /// <summary> |
| /// A data control to reference a method in the current page instance. |
| /// </summary> |
| public class PageMethodDataSource:ObjectDataSource |
| { |
| public PageMethodDataSource() |
| { |
| ObjectCreating += OnObjectCreating; |
| } |
| protected override void OnInit(System.EventArgs e) |
| { |
| base.OnInit(e); |
| TypeName = Page.GetType().BaseType.ToString(); |
| } |
| void OnObjectCreating(object sender, ObjectDataSourceEventArgs e) |
| { |
| e.ObjectInstance = Page; |
| } |
| } |

Just created a style and after I downloaded the style, I noticed the background sprite that I had upload was being referenced back to the telerik website.
Should it not reference the local copy of the image?
| div.RadMenu_internalweb .rmItem .rmLink:hover .rmText { |
| background-image: url('http://stylebuilder.telerik.com//ImageHandler.ashx?mode=get&Skin=internalweb&Control=Menu&Suite=aspnet-ajax&file=internalwebsprite.png'); |
| background-position: 100% -26px; |
| padding-left: 0px; |
| height: 25px; |
| margin-top: 0px; |
| padding-right: 28px; |
| background-color: transparent; |
| } |

Hello,
I'm really having too much troubles using RadListView. Now I'll try to briefly explain.
The project that I started to work on is a very specialized search engine using a complex data layer that can use one or more databases simultaneously. So I thought that was a good idea to use a RadListView with RadDataPager for a flexible paging.
Initially I was using the ASP.Net Controls version 2009.3.1103. Soon I realized that something was not going on as I expected: in fact, starting with no Data Source specified, after a postback initiated by another control, the data was not shown and the "no data template" was always presented. After a long search, finally I found a post in this forum that pointed me to this known bug.
Well, I did update the controls and the bug disappeared. But, unfortunately, now I'm stuck on the programmatic creation of the control. In fact I discovered that in design-time it is not possible to configure the RadListView via "smart tag option" since a valid data source is not specified.
A search engine cannot perform any query in a first page load, so I need to do all the data source job (dinamic query creation in response of the user parameter input) in a "if Page.IsPostBack then [...] End If" code block.
That's why I passed to the programmatic creation of the control.
Now, and this is the main problem to solve, it seems that there is no way to avoid this error message:
The RadListView control does not have an item placeholder specified.
For more clarity, this is the code-snippet in which I "try" to create the RadListView:
| Private rlvResults As RadListView |
| Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init |
| Me.BuildListView() |
| End Sub |
| Protected Sub BuildListView() |
| Me.rlvResults = New RadListView() |
| With Me.rlvResults |
| .AllowCustomPaging = False |
| .AllowCustomSorting = False |
| .AlternatingItemTemplate = New GooWayTemplates.AlternatingItemTemplate() |
| .EditItemTemplate = New GooWayTemplates.EditItemTemplate() |
| .InsertItemTemplate = New GooWayTemplates.EditItemTemplate() |
| .ItemTemplate = New GooWayTemplates.ItemTemplate() |
| .EmptyDataTemplate = New GooWayTemplates.EmptyDataTemplate() |
| .LayoutTemplate = New GooWayTemplates.LayoutTemplate() |
| .SelectedItemTemplate = New GooWayTemplates.ItemTemplate() |
| .ItemPlaceholderID = "itemPlaceholder" |
| AddHandler .NeedDataSource, AddressOf rlvResults_NeedDataSource |
| .AllowPaging = True |
| End With |
| Me.placeHListView.Controls.Add(Me.rlvResults) |
| End Sub |
Where am I wrong?
This is a fundamental step in a big project and I'm really confused :-)
Thanks in advance.

Hi, there's a problem with radtextbox.
I've 3 radtextblock with enabled property set false at design time in my .aspx page, a raddatepicker with a customvalidator and a button to start the validation.
When validation occours (on click button) the enabled property of the 3 textbox turn to true. Here an example:

I'm adding items to a RadComboBox server-side like so:
Then later I'm selecting the item I want to be initially selected in the combobox on the server-side too:
I have registered a client-side event listener to the "OnClientSelectedIndexChanged" event. However, this event seems to be firing as soon as the page loads as if the user has selected a value using the combobox. Is this expected behaviour, something broken or me doing something wrong? I only want to be notified when the value has been changed by the user from the value selected server-side - how would I achieve this?
I am using version 2008.3.1314.20
Thanks,
James
Addendum: I've just realised that the client event only seems to be fired once when the page loads and never again. That is, the event is not being fired when the user selects a new item. Help!

Hi,
I have a MasterPage where I have declared a RadAjaxManager
Into other pages I am using the RadAjaxManagerProxy .
In a form I have RadAjaxManagerProxy which update an <asp:Panel> which contains a FromView which contains a RadEditor.
After a "postback" the RadEditor loose its behavior.
I have search on you forrum, I have read your documentation but it doesn't work.
Best regards.

If you create an imagemap area in IE, it is transparent. If you do it in Safari, Firefox or Chrome it is not. Can you please fix this in the next version? Is it possible for me to fix this with a custom javascript?

I updated to the latest version of RadControls for ASP.NET AJAX (2008.2 1001 - Oct 1, 2008) and now the header (HeaderTemplate) row will no longer show for all my RadComboBox controls when I do some type of data binding in the HeaderTemplate. If there is no data binding it works. Something broke in this last version and the basic "<%" usage is no longer supported.
Not working HeaderTemplate:
Not working HeaderTemplate:
| <HeaderTemplate> |
| <table cellpadding="0" cellspacing="0" border="0"> |
| <tr> |
| <td style="width:90px; vertical-align:top; text-align:left;"><%= ((SessionState.Language == Natr.Classes.Language.Spanish) ? "No. de Stock" : "Stock Number")%></td> |
| <td style="width:320px; vertical-align:top; text-align:left;"><%= ((SessionState.Language == Natr.Classes.Language.Spanish) ? "Descripción" : "Product Name")%></td> |

I'm working with Telerik v. 2009.2.701.35
I have some buttons on a form rendering inside a table. If I create them as <input type="button> they do not decorate at all. If I change it to a <button> tag, it seems to pick up the css from the skin's style sheet and apply the correct background, but the right side border is missing. This right side border is supposed to be the background of the <a> tag, based on what I've seen in the demo.
I tried using javascript to style the form in real time, and it works, but again it skips the buttons. It styles the other form elements just fine. The example I followed to do this is here: http://www.telerik.com/support/kb/aspnet-ajax/formdecorator/decorate-dynamically-added-controls-by-using-radformdecorator.aspx
Here is an example of the HTML on my page in which buttons are not being decorated.
I don't think my CSS is causing this issue because like I said, the <a> tag wrappers are not being created at all.
Thanks for looking,
-Chris

Hi,
I need to set the DataNavigateUrlFormatString of the GridHyperLinkColumn to some thing like this.
http://xyz.com?id=rownumber.
Here rownumber is the number of the row in which the linkbutton will be there.
Eg: for a linkbutton in the third row,
the url should be like http://xyz.com?id=3.
How can this be achieved in the ascx file?( or even via code?)
