RadCombo javascript throws exception on SelectedIndexChanged when Value is apostrophe

Hi all,

Very simple. I am binding the RadCombo in markup and code-behind as follows. So, when the user selects a value in the RadComboBox that contains an apostrophe, some javascript exception is thrown and the server-side postback event handler is never invoked. We are using version 2011.2.712.35.

Please help.

Thank you,

Dan

Markup:

<td>

<telerik:RadComboBox ID="request__place_id" CssClass="LabelValue" AutoPostBack="true"

OnSelectedIndexChanged="request__place_idSelectedIndexChanged"

runat="server">

</telerik:RadComboBox>

</td>

Code-behind:

var values = from info in result.Descendants("place")

select new

{

PlaceId = info.Element(

"place_id"),

Name = info.Element(

"name")

};

this.request__place_id.Items.Clear();

this.request__place_id.Items.Add(new RadComboBoxItem(string.Empty, string.Empty));

foreach (var value in values)

{

this.request__place_id.Items.Add(new Telerik.Web.UI.RadComboBoxItem(value.Name.Value, value.PlaceId.Value));

}

Problem finding correct PublicKeyToken for Web.config

My colleague started on Telerik a few weeks ago. I am about to try and get up to speed. He gave me a project which I have set up with data on my workstation. We got Telerik, MM.NET and its Telerik subclasses installed, and figured out how to manually browse to the Telerik.Web.UI file i the Telerik install location.

However, I had downloaded a slightly later version of Telerik, Version=2010.2.929.35, from our shared account. The SP.NET app still had one reference error, and if we tried run it it would barf on the web.config file saying it could not find the Telerik.Web.UI.

My colleague showed me an email or exchange on forum from Telerik saying that for a the version in question, you could get the PublicKeyToken from the xml file.

We are using .NET 3.5 version, so in the \35 folder, I verified the version number in the properties of the Telerik.Web.UI.dll as 2010.2.929.35.

However, in the Telerik.Web.UI.XML, the only reference to a PublicKeyToken was in these two lines:

            <example>
                <code lang="CS" title="C#">
            spell1.CustomDictionarySourceTypeName = "RadSpellExtensions.CustomDictionarySource, RadSpellExtensions, Version=1.0.0.0, Culture=neutral, PublicKeyToken=b5e57ccb698eab8e";
                </code>
                <code lang="VB" title="VB">
            spell1.CustomDictionarySourceTypeName = "RadSpellExtensions.CustomDictionarySource, RadSpellExtensions, Version=1.0.0.0, Culture=neutral, PublicKeyToken=b5e57ccb698eab8e"
                </code>
            </example>

Naturally, the value there when placed in the web.config file did NOT solve the problem.

On another thread here

http://www.telerik.com/community/forums/aspnet-ajax/general-discussions/telerik-web-ui-radchart-is-not-defined.aspx

we found a reference to the version number, and a PublicKeyToken:

add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI, Version=2010.2.929.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4"/>

so for the heck of it, we tried it in the web.config, and the program fired up.

So the question is, where are we SUPPOSED to be able to get the correct PublicKeyToken for a version of the .dll??

It is clearly not in the xml file in the \35 folder with this version.

RadRotator WrapFrames not wrapping

Hello all,

I setup a vertical CoverFlow RadRotator in a user control bound to a generic List<> but i cant seem to get the rotator to "wrap" using WrapFrames="true" and i only get 1 cycle of the items in the List<>. I've tried changing the binding to IEnumerables and string[].
For this example, the List<> is just List<string> vpaths.

Heres the markup for the rotator.

<

telerik:RadRotator ID="rotatorVerticalMediaItems" runat="server" Height="400px" Width="400px" CssClass="ucCoverArtRotatorV_RotatorStyle" RotatorType="CoverFlow" PauseOnMouseOver="false" Skin="Black" ScrollDuration="2000" ScrollDirection="Down,Up" FrameDuration="1" ItemHeight="300px" ItemWidth="202px" WrapFrames="true">

</div>

</ItemTemplate>

</telerik:RadRotator>

Thanks in advance.

Grid getting disappeared on updating any of the rows information

Hello,
I'm using the telerik grid but when I try to update any of the information, the grid disappears completely. Following are the steps I follow:
1. Click on the 'Edit' button for any of the row and update any information.
2. Press Update button.

As soon as I press 'Update' button, grid disappears. And when I reload the page, it appears again.
Following is the html code:

ScriptManager.RegisterStartupScript(this, this.Page.GetType(), "dialog", script, true);

}

Can some one help me with this issue?

Menu and vavigation blocking

Hi,

We are working on a rich ASP.Net application using most of Telerik controls and we are facing a strange issue. Given below is the scenario:

1. User visits our site.
2. Navigates to different pages using different Menu options (RadMenu - on Top of page, RadPanelBar - on Left).
3. in the same browser window/tab, User opens any other website e.g. msn.com.
4. Now, user moves back to previous page (our website) using browser's back button.

Once user is back on our website, both left and top menu bars are not functional i.e. clicking on menu items performs no action. Clicking or double clicking a menu makes no difference. It start behaving in a way that if there is no Page linked to any of the menu.

What could be the reason? Any fixes/help?

We are using RAD Asp.Net AJAX Q2 2011

Thanks in acticipation!

Can't see control from another tab

OK, I just inherited a project that uses these controls and I am not sure how to word this. I have a page thatuse radtabstrip and multipage. I have several pages and when I click on to save, the tables are getting updated with all the values with the first tab and doesn't see anything else. I also get the identity of the record and save it as a session variable for a child table and it doesn't see it either. Is it possible for me to see the controls on all the tabs? If so, how do I do it?

Setting SelectedDate on RadDateTimePicker but leaving it Empty on Page_Load

I have a RadDateTimePicker that needs to stay empty when the page loads. When the user selects a time from the TimePopupButton, the Date & Time are populated in the RadDateTimePicker. The problem is the date portion that's populated is always today's date. How can I default this to another date, for example DateTime.Now.AddDays(1)?

If I set the "SelectedDate" property to DateTime.Now.AddDays(1), then the date that's populated works as expected. But setting "SelectedDate" causes the RadDateTimePicker to display this date when the page loads. I need it to be empty on page load and only populated if the user selects something from the PopUpButtons.

[Solved] Cross-site Script vulnerability in WebResource.axd

We have found a Xss vulnerability in the Telerik.Web.UI.WebResource.axd [_TSM_CombinedScripts_ parameter], where it is possible to edit the javascript. We are currently using an older version of the library (2009.3.1103.20). Can anyone confirm that this issue is fixed in the latest release, and in what version was this issue solved?
