License question

Hi,
I'm wondering if the license gives possibility of creation of CMS which uses the telerik controls?
What is the meaning of "design time" working with controls. If I create the CMS where on the web page users will be able to create their own websites and I design modules which are based on telerik controls does this mean that I do not respect the license? Or the "design time" working with controls mean that they are used in the IDE like Visual Studio?

Can't find modified item in Update command

Hi all,

I got a grid with some lines. I am using an edit column and handle the update command, but I can't find the modified row in the "e". I guess it is somewhere in the e.Item.DataItem, but I can't see it.

Anyone can help me?

GridAttachmentColumn: ConditionalPostback & "Object Required" Errors

I am encountering strange issues in my continuing quest to get GridAttachmentColumn to play nice with AJAX.

I have implemented conditional postback as follows:

Code behind

if (this.Master != null)

{

var ajaxManager = (RadAjaxManager)this.Master.FindControl("TelerikAjaxManager");

if (ajaxManager != null)

{

ajaxManager.ClientEvents.OnRequestStart += "ConditionalPostback";

}

Script in the content page

function ConditionalPostback(sender, eventArgs)

{

var eventTarget = eventArgs.get_eventTarget();

if (eventTarget == "<%=this.AttachmentsGrid.UniqueID %>")

{

var eventArgument = eventArgs.get_eventArgument();

if (eventArgument.indexOf("Update") > -1 ||

eventArgument.indexOf("PerformInsert") > -1)

{

eventArgs.set_enableAjax(false);

}

function GridOnCommand(sender, args)

{

if (args.get_commandName() == "DownloadAttachment")

{

var manager = $find('<%= RadAjaxManager.GetCurrent(Page).ClientID %>');

manager.set_enableAJAX(false);

setTimeout(function () { manager.set_enableAJAX(true); }, 0);

}

Snippet of the RadGrid

<telerik:RadGrid

AutoGenerateColumns="False"

AutoGenerateEditColumn="True"

DataSourceID="AttachmentsDataSource"

ID="AttachmentsGrid"

runat="server">

<MasterTableView

DataKeyNames="Id"

</telerik:GridAttachmentColumn>

</Columns>

</MasterTableView>

<ClientSettings>

</ClientSettings>

</telerik:RadGrid>

The grid is contained within a TabStrip with associated pageviews.

I can upload an attachment, delete etc. but when I click a link in the tab strip, i receive two errors:

I copied from Firebug / IE.

After ok'ing the alerts, the page loads but with all the telerik styling and functionality in the page broken.

Any ideas what is going on?

Richard

Update (14/10/2011): The issue is caused when there is a RadComboBox within the PageView of the TabStrip.If the ConditionalPostback does not fire the first time, I'm fine but if it does, this error happens. This seems strange to me because afterwards, AJAX is back on and ConditionalPostback doesn't actually do anything when navigating through the TabStrip PageViews.

Even if I just put in a simple

<

telerik:RadComboBox runat="server" ID="test"></telerik:RadComboBox>

I get the errors.

I hate JavaScript.

Paging/ NeedDataSource

Hi,
I am looking at a small issue with one of our grids. Just looking to find out some additional information about the RadGrid's events. Should the NeedDataSource event be fired every time we change pages? And if so is there a way to turn it off. We pass the Grid say 30 rows, we would like our users to be able to page between these rows without having to call NeedDataSource everytime.

Thanks,
Michael

Applying error 'style' and messages to controls from an Ajax call

We are new to Telerik and are still in the evaluation stages. I am putting together a prototype using the ASP. NET Ajax controls from Telerik and can't fiqure out how to present errors on the client. Our prototype is ajax based. So once the page is loaded on the client the user loads new data and updates changed data with Ajax calls. We are using JQuery as our Ajax comunication script engine. However, I have not been able to figure out how to configure the Telerik controls (such as the RadTextBox or RadDateInput) to display with the error style and show a server error message returned from the Ajax call. I am looking for some kind of client-side api that would support this scenario, but am not finding anything in the documentation.

Any help with this scenario is appreciated.

EnableSingleInputRendering and FormSubmit

Hi,
When EnableSingleInputRendering is "true" for a PasswordField (RadTextBox), all submit behaviors of form and buttons are not working.

<form id="form1" runat="server" defaultbutton="LogOn" acceptbutton="LogOn" >

<telerik:RadButton ID="LogOn" runat="server" Text="Login" OnClick="LogOn_Click" UseSubmitBehavior="true">

</telerik:RadButton>

Neither ENTER triggers postback nor can I invoke it programmatically from JS.

Clicking on the button, however, works.

Thanks for help,
Max

Automatically scroll to details

When the user expands a row, then the grid refreshes. The detail rows are not visible because they are displayed below the screen. The user must scroll down to see the details.

Instead, we want the user to see the details without having to scroll. How?

RadCombobox stopped getting values

Hello
I am using Radcontrols on Telerik ASP.net Controls version 2009.2.826.35 and our combobox code stopped working with error code

Telerik.Web.UI.WebResource.axd:15Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: Input string was not in a correct format.

My code of that part can be seen here.

<telerik:RadComboBox ID="ddlRoom" runat="server" Style="width: 55px" OnClientSelectedIndexChanged="OnRoomAmountChange">

<Items>

<telerik:RadComboBoxItem Value="1" Text="1" />

<telerik:RadComboBoxItem Value="2" Text="2" />

<telerik:RadComboBoxItem Value="3" Text="3" />

<telerik:RadComboBoxItem Value="4" Text="4" />

<telerik:RadComboBoxItem Value="5" Text="5" />

</Items>

</telerik:RadComboBox>

function OnRoomAmountChange() {

var radRoom = $find('<%= ddlRoom.ClientID %>');
