RadButton does not work with .net ajax ConfirmButtonExtender

Hi everyone,

I did not find any forum posts for this though I would think that someone else would have discovered/had an issue with this by now. It appears to me that the ConfirmButtonExtender does not work with the RadButton control. Upon canceling the confirm the Click event code is still called. Is this expected behavior or a legitimate issue? I am using the latest SP for Q3 2010 ASP.NET controls (2010.3.1317.35).

Thanks,

[Solved] How to connect to database at runtime

Hi,
I am new to Telerik controls so don't understand all of the consepts yet. I have been playing with the Scheduler since it is the first component I need to implement.
I have a SQL Server and I used the datasource wizzard to connect. Things are working just fine. But my real life application needs to connect to many different databases with the exact same structure at run time depending on logged in user (I have several users and each of them have their own database on the same server).

So my question is how can I override the connectionstring (or some other method) in code behind to change the database name just before the Scheduler loads?

Conflict between ASP.Net AJAX RadComboBox and Silverlight RadChart

I am currently testing out Trial versions of the ASP.Net AJAX Rad Controls and the RadControls for Silverlight. I have the following in the Visual Studio 2010 project

Silverlight 4 Application (SL App) with a RadChart in it.
ASP.Net User Control with a reference to the the SL app: <object data="data:application/x-silverlight-2," ...> ... </object>
Master Page including the RadScriptManager
ASP.Net form with related RadComboBoxes and the above user control

I was trying to refresh the RadChart in the SL App with value from the selected values in the ASP.Net AJAX RadComboboxes. I figured out how to pass parameters to the SL App. However, with the SL App present on the page, the RadComboBoxes do not drop down. Is this a known issue? Is there a fix or a workaround?

I've attached a simpler version of the project for your reference. The outcome is the same whether I use a Master Page or not.
Thank you,

Wes C.

Upgrade from .net2 2009 Q2 to .net4 Q3 radgrid/radajaxloading panel problem

After upgrading, I get this error when any event is fired from my radgrid, ONLY when the RadAjaxLoadingpanel is used. The scenerio fails with client script error: Message: Object doesn't support this property or method

Fails:
Grid/RadAjaxManager/RadAjaxLoadingPanel
Grid/RadAjaxPanel/RadAjaxLoadingPanel

Works:
Disable ajax!
Grid/RadAjaxManager/RadAjaxLoadingPanel
Grid/RadAjaxPanel/RadAjaxLoadingPanel

Basically, using the loading panel fails under all circumstances. The project does include a reference to the AjaxControlToolkit.dll(v 1.0.11119). The grid has templated radcombos, numerictextboxes, radtextboxes, and linkbuttons in both the command template and command templates. There is also another grid inside the editItem template. I've read dozens of forum threads and found no help for the exact issue I'm having.

full error below:

radcombos and same address option

Hello,

I am capturing 2 sets of addresses, a job site address and a job ship address, and am using radcomboboxes as shown in the related combobox demo. I am using the comboboxes for city, state, county, zip and country. I have a checkbox so that if the ship address is the same as the site address one can check the box and the values will be copied from the site address to the ship address. In addition, I'd like to be able to change the ship address if necessary (after checking the box) by making use of the comboboxes. I currently have a function for the onclick event of the checkbox called DupAddresses(). Inside the DupAddresses() function I am calling the requestItems event and passing the appropriate data for each combobox. I don't get any error messages, and when I put in javascript alerts and codebehind breakpoints, it looks like the appropriate data is going to the right place. When the checkbox is clicked, I am able to successfully use combobox.set_text to set the appropriate text in the fields, but I have not been able to figure out how to databind the updated combo values to the comboboxes - instead they retain the previous values. For example, if the original ship city/state was Birmingam/Alabama and the site city/state is Atlanta/Georgia, if I click the checkbox, I can change the ship city/state combo text to show Birmingham/Alabama, but if I click on the ship city combo the list still reflects those cities found in Alabama, not Georgia. Any ideas/suggestions would be great.

Thanks.

Some missing important features

Hi,

we are using telerik TreeList in our project but there are some missing base feature that obstacle out programming.
Here same examples :
- when paging is enables, second level items may appear some in current page and some other in next page
- edititem template is not present; so, if we need to save one row, we are forced to render all items with control that allow modification (eg. textbox, drop down)
- loadOnDemand for each node is missing, so we arte forced to load all data at a time

I need to know if this feature will be delivered in Q4 2010 version of Telerik ASP.NET Ajax Controls. When Q4 2010 will be avaiable (1 week/1 month)?

Thanks a lot for your support
