Value of type 'String' cannot be converted to 'Telerik.Web.UI.RadTextBox

i am trying to sample the following demo code: (vb)
http://demos.telerik.com/aspnet-ajax/ajax/examples/manager/dynamicajaxsettings/defaultcs.aspx?product=grid

everything looks ok when i apply the code to a single page aspx and ascx. But when i try to put the aspx code in a master.page it throws the following error. Object ref. not set to an instance.....for the ascx line:

RadAjaxManager.GetCurrent(Page).AjaxSettings.AddAjaxSetting(editButton, Me.Page.FindControl("DivExternalForm"), TryCast(Me.Page.FindControl("RadAjaxLoadingPanel1"), RadAjaxLoadingPanel))

subroutine:

Protected Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As GridItemEventArgs)

If TypeOf e.Item Is GridDataItem Then

Dim editButton As ImageButton = TryCast(TryCast(e.Item, GridDataItem)("EditColumn").Controls(0), ImageButton)

RadAjaxManager.GetCurrent(Page).AjaxSettings.AddAjaxSetting(editButton, Me.Page.FindControl("DivExternalForm"), TryCast(Me.Page.FindControl("RadAjaxLoadingPanel1"), RadAjaxLoadingPanel))

ElseIf TypeOf e.Item Is GridCommandItem Then

Dim insertButton As LinkButton = TryCast(TryCast(e.Item, GridCommandItem).FindControl("btnInitInsert"), LinkButton)

RadAjaxManager.GetCurrent(Page).AjaxSettings.AddAjaxSetting(insertButton, Me.Page.FindControl("ctl00_ContentPlaceHolder1_DivExternalForm"), TryCast(Me.Page.FindControl("RadAjaxLoadingPanel1"), RadAjaxLoadingPanel))

Where did my client-side functionality go?

Hello,

I have a page that was using "RadDock for ASP.NET" that I upgraded to the latest version of "RadDock for ASP.NET AJAX".

After following this article:
Migrating From RadDock ASP.NET To ASP.NET AJAX

I finally got the page to compile again...but I have no client-side functionality whatsoever.
ex.
clicking the expand/collapse arrow or the "x" to close the dock does nothing
"EnableDrag" is set to true, but I cannot drag a dock
The cursor always stays the normal pointer arrow (in the old version hovering over the dock's title bar turned the cursor into the "4-way arrow" and hovering over the expand/collapse arrow or the "x" would change the cursor to the "hand")

It's like all client functionality is disabled? How do I re-enable?

Hi,
Here i have a senerio in RadScheduler regarding appointment sorting. I have an appointment, that is created for multi days and scheduled time is 12:00 am to 01:00 am.

But the problem that i am facing is multi days schedule appointments are comming at top. Please give me some idea to arrenge these appointments in sorting order that match my requirement.

Thanks,

[Solved] Add text box to Radchart?

Is it possible to add a text box to a Radchart?

I am charting financial data over time. Periodically an event happens which affects the data and in the data source, these events are recorded. If possible, I would like to create another textblock in code, read in these events from the data source and write them out as text inside the chart background area (without affecting the chart and labels which are working nicely).

I realise I can do this outside of the chart, but I have a nice sized space inside the background area of the chart, below the series legend which would be otherwise unused.

thanks,
fudoki

Internet Explorer (8 and 7) don't display Modal background overlay

Unlike every other browser, Internet Explorer (8, 8 compatibility mode, 7) does not display the background overlay that grays out the background and makes everything outside of the window unclickable when Modal is set to true. There are no Javascript errors and looking at the source you see that "<div style="position: absolute; left: 0px; top: 0px; z-index: 3000; background-color: rgb(170, 170, 170); opacity: 0.5; width: 1387px; height: 1574px;" unselectable="on" class="TelerikModalOverlay"></div>" isn't there when using Internet Explorer, even though it is for Firefox. I can't find anyone else with this problem after searching Google and these forums.

WebService Load with Server Side Refresh

Hello,

I have a Treeview that is loadonDemand via a webservice and works fine. I have PersistLoadOnDemandNodes Set to TRUE as i need to do some server side things when a user clicks the Node.

All works fine separately but not together.

If a user clicks the expand Icon the Nodes are loaded just fine.
If the User click the Node my server side code renders fine.

However is a user doesnt expand and just click the node the Server side code is execute and you see the Webservice load the Nodes and then they disappear.

I think this has to do with the AjaxPanel its wrapped in from the Masterpage. Any ideas

[Solved] Help for VS2008 users

If I'm not mistaken, the only documentation available to VS2008 users is online or in a CHM file that has to be downloaded separately.

So we have to have 2 help readers open now, rather than one.

Nice one guys. Real forward thinking.
