Hi,
I am using the AutoCompleteBox oggetot, I set the options but when I open the aspx page and on the AutoCompleteBox I press the backspace button, I get this error: "Run-time error of Microsoft JScript: Can not get value of property 'TrimStart ': Object invalid or not defined "

My code to asp is:

<telerik:RadAutoCompleteBox ID="RadAutoCompleteBox1" Runat="server"

DataSourceID="SqlDataSource1" DataTextField="Descrizione"

 

DataValueField="Id" InputType="Text" Width="330px" Delimiter=""

 

DropDownHeight="150px" DropDownWidth="330px">

 

</telerik:RadAutoCompleteBox>

Thanks

Hi,

I have some issues with Radgrid Pager, when I give it some specific height, pages is acting like a crazy, override my button view when it opens.
So is it possible when I click over radgrid pager dropdown, to open "UP" , not down? So it won't override my button below it.

Hi folks

I have a rather serious problem trying to get a radTreeView to show changes in the underlying database and therefore datasource. My scenario is as follows.

1. In the Load event hander, the radTreeView is initialized as in the following example code:

                radCommentTreeView1.DataSource = Nothing
               
                // Initialize custom data object from custom hierarchical data source class
                cdsPubCommentDataSource = New CommentDataSource(1)
                radCommentTreeView1.DataSource = cdsPubCommentDataSource

                // Configure radTreeView from datasource fields
                radCommentTreeView1.DataFieldID = "ID"
                radCommentTreeView1.DataFieldParentID = "ParentID"
                radCommentTreeView1.DataTextField = "Content"

                // Bind radTreeView to datasource
                radCommentTreeView1.DataBind()

2. The page loads with radTreeView rendered correctly

3. User attempts to add or delete a node by clicking a button with a server-side handler ....

4. ... so that the postback cycle begins in the server-side code, with the Load handler from (2) above running again, to rebind the radTreeView

5. ... only after which the server-side button handler is run, successfully running an SQL command through another BLL business object (i.e., the SQL database is successfully modified ) ....

6. However, when the page renders after the postback, the radTreeView still reflects the original node hierarchy from (4) above, before the node was deleted in (5).

Could someone indicate how this process ought to be achieved within the cycle of a single postback - if I try to rebind again after the button handler, none of the radTreeView nodes render properly at all, presumably because the process must occur no later than the Load handler?

I am aware of the idea of using the INotifyPropertyChanged interface for the datasource object, and already have the event in question being successfully fired up from the DataSource object, namely a PropertyChanged event indicating a change in the DataSourceView object, but I am not sure how a PropertyChanged event handler can help in the scenario I describe - the PropertyChanged event handler in the page is still invoked before the button handler, and so the database has not been changed at the time the event handler runs. Is the PropertyChanged event the correct way forward, or is there another approach better suited for refreshing the radTreeView within a single postback cycle?

Thanks if someone can point me in the right direction with this problem.

Hello,

I have an application which uses RadAjaxManager to populate RadComboBoxes as users make selections on the page.  This works correctly most of the time however roughly 10% of the time the user will make a selection from combo box 1 which is supposed to populate combo box 2, the Ajax request seems to fire but it loads no values in combo box 2.

I have tested and the error is definitely not related to the data.  I can test using the exact same data that was used by someone who encountered the error and combo box 2 will load correctly for me.

Here are the Ajax settings for Combo Box 1:


Here is the markup for combo boxes 1 & 2:


Here is the associated code behind function:


Everything here seems fairly simple so I am having a really hard time understanding why my users are encountering this issue.  The fact that it is so hard to replicate has also made this extremely difficult to troubleshoot.  Any help at all would be appreciated.

Thank you!

EDIT:  Some further information... When the issue happens it seems to persist for a few minutes.  All AJAX calls seem to fail but no error is displayed and nothing is reported to the event logs on the web server.  After a few minutes and a browser restart everything works fine once again.

This has me stumped.  It just started showing up one day.  We get a javascript error in some of the pages.  The error is in the WebResource.axd.  It seems to be referring to the html <col> fields related to the rad tree. It looks like it chokes on the columns with no width specified.
The really odd thing is that it works fine when it is launched from VStudio (debugging).  It errors on our dev server when we use the unqualified server name, but works when we use the fully-qualified name (http://server/page.aspx vs http://server.domain.com/page.aspx).  On production, it errors when we go through the load balancer, but not when we use the unqualified name or the non-load balanced name.  So, its hard to narrow-down the conditions.

Anyway, here is the javascript error message that we are getting:

We have a Grid with Export buttons.  The export functions as it should going to a new window.  When we click to go to another page on the grid it suddenly loses all paging, the command row, and even data in one of the columns.  It appears that when it exports it reformats the grid to remove paging and commands but then it doesn't enable the them again so when the grid posts back to get to the next page, it returns the grid w/o formatting.  We are using advanced data binding.  Here's some code snippets.  Does anyone know how to get around this?  Thanks.

It is possible to define (programmaticaly) all the parameters in a series when I use DataBind


for a dynamic page I need to control everyting from the CodeFile (C#)

thanks in advance

Hello,

I have replaced the Microsoft ScriptManager with the RadScriptManager in my SharePoint site's master page.  That part seems to work just fine.  However, when I try to use some of the advanced features of RadScriptManager like EnableScriptCombine and TelerikCdn, they do not seem to function. It's as if these setting are getting ignored entirely, so I was wondering if they are even designed to work in SharePoint 2010?  Or perhaps there's some additional configuration steps needed to make them work?

I have successfully used these settings in a stand-alone web site (not hosted in SharePoint) without problem, even on the same machine.  Any help you can offer would be appreciated.  We are desperately trying to use these features to reduce latency in a client's production site.

Thank you,

Chris

P.S. I am currently using Telerik AJAX controls version 2011.1.413.35
