preventing a page refresh with multiple radrating controls

I have a .net listview in which i placed a radrating control. For each record in the listview a radrating control gets rendered. When someone clicks on the control to submit a rating, the whole page refreshes. I was wondering if anyone could suggest what i might be missing that's causing the whole page to refresh? I thought one of the great benefits of the telerik controls is that i just need to drop a scriptmanager on the page and it handles all the postback events.

If there's an online tutorial which demonstrates this, please post the link. Otherwise I am open to any suggestions.

Thanks

RadComboBox with empty ODataSettings throws "Microsoft JScript runtime error: Unable to get value of the property 'Name': object is null or undefined" - 2011.3.1305.40 build of ASP.NET AJAX components

I was moving from the latest (2-3 weeks old) trial to 2011.3.1305.40 build of the ASP.NET Ajax components, when I startet getting the following error message:

Microsoft JScript runtime error: Unable to get value of the property 'Name': object is null or undefined

After getting this, you start receiving all kind of JS errors, formatting errors in the RadGrid, etc. I spend a few hrs debugging it, when I eventually figured out it is something to do with the empty ODataSettings tag, which you get when working with the designer. I started removing the components from the page so I can figure out which one is breaking the runtime, turned out it is the RadComboBox. Below is the source of a page which will break 10 out of 10 times - tought I save someone else some time figuring it out.

Removing the following will fix it:

How To Set TreeView Max Levels

I would like to know if there is a way to set a maximum number of levels to render when binding to a datasource?

We are using radtreeview with Sharepoint 2007 like this:

<asp:ContentPlaceHolder ID="PlaceHolderVerticalNav" runat="server">

<telerik:RadTreeView Runat="server" id="RadTreeView1" datasourceid="topSiteMap" EnableEmbeddedBaseStylesheet="false" EnableEmbeddedSkins="false"></telerik:RadTreeView>

<PublishingNavigation:PortalSiteMapDataSource ID="topSiteMap" Runat="server" SiteMapProvider="CombinedNavSiteMapProvider"

EnableViewState="true" StartFromCurrentNode="false" StartingNodeOffset="0" ShowStartingNode="false"/>

</asp:ContentPlaceHolder>

Our datasource has 10 levels deep, but I want to restrict it to displaying just the first 3 levels.

Any tips would be helpful.

How to clear the content in a RadTextbox when OnFocus

Hello,
I am trying to clear the content of a RadTextBox when user focuses on the textbox. I tried several ways but could not clear the content using javascript.

"LASTNAME" is written into a RadTextbox and when user focuses to this RadTextbox, "LASTNAME" should be cleared so that the user can write his/her name...

I tried to clear it using javascript;

<script type="text/javascript">

function clear()
{
$find("<%=RadTextBox1.ClientID %>").clear();
}
</script>

But it did not work. It reads the clear method but does nothing. So how can I clear the content, any ideas?

Thanks,
Ervin

To Support telerick controls for Multi versioning

Hi there,
We are adding the telerick dlls dynamcially through reflection dynamically at run time. We had the issue of loading the embeded resources in reflection . So, we disabled the telerick embeded resources and loadin it dynamically. Our user controls are not designed in ascx rather they are defined as webcontrols. The issue that i am facing is, i am able to add all the required resources dynamically to my customer control dll and while executing the telerick dll resrouces, say the Radbutton.js file, i am getting $(telerick) is undefined.

Please let me know is it possible to load the telerick resource files dynamically in webcontrols using scriptreferences, if so, what are the additional parameters that i need to add? Any help would be appreciated.

Please note that i have added all the required js / css files also.

Thanks,
My script reference method, passin the dll and the reousrce details,

public IEnumerable<ScriptReference> GetScriptReferences()

{

this.EnableEmbeddedScripts = false;

// ClientScriptResource("Telerik.Web.UI.RadButton", "Telerik.Web.UI.Button.RadButton.js"),

ScriptReference reference =

new ScriptReference();

reference.Name =

"Telerik.Web.UI.Button.RadButton.js";

reference.Assembly =

"Telerik.Web.UI, Version=2010.3.1215.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4";

string[] Names = reference.Assembly.Split(',');

string DLLName = Names[0].Replace("\\", "");

string VersionNumber = Names[1].Split('=')[1].Replace("\\", "");

string Culture = Names[2].Split('=')[1].Replace("\\", "");

string PublicKeyToken = Names[3].Split('=')[1].Replace("\\", "");

reference.Path =

"~/MyScriptHandler.ashx?Assembly=" + DLLName +

"&VersionNumber=" + VersionNumber +

"&Culture=" + Culture +

"&PublicKeyToken=" + PublicKeyToken +

"&ResourceName=" + reference.Name;

return new ScriptReference[] { reference };

}

My ashx code to load the resource file dynamically,

public void ProcessRequest(HttpContext context)

{

string DLLName = context.Request["Assembly"];

string VersionNumber = context.Request["VersionNumber"];

string Culture = context.Request["Culture"];

string PublicKeyToken = context.Request["PublicKeyToken"];

string ResourceName = context.Request["Resourcename"];

string TypeFQN = DLLName + ", Version=" + VersionNumber + ", Culture=" + Culture + ", PublicKeyToken=" + PublicKeyToken;

Assembly ResourcesAssembly = Assembly.Load(TypeFQN);

Stream IOFile = ResourcesAssembly.GetManifestResourceStream(ResourceName);

byte[] bytes = new byte[IOFile.Length];

IOFile.Read(bytes, 0, bytes.Length);

string contentType = getContentType(ResourceName);

if (contentType == "text/plain")

{

string outputfile = string.Empty;

if (HasUtf8ByteOrderMark(bytes))

{

outputfile =

Encoding.Default.GetString(bytes).Substring(3);

}

else

{

outputfile =

Encoding.Default.GetString(bytes);

}

context.Response.Write(outputfile);

}

else

{

context.Response.BinaryWrite(bytes);

}

Does RadSpell require different license?

Hi,

In my ASP.NET application, we have used RadEditor control.
RadEditor.Net2.dll version 6.5.0.0

Now I have to implement Spell check functionality for all inputs where RadEditor control has been used.
I think, the ideal way it seems is using RadSpell.Net2.dll.
But the issue is that, I have only source code of website, but not the installer. So I am not sure, if installer is containing RadSpell DLL. Also, the installer is at client's environment, so I think its difficult to check for us.

If you could please let me know, do we need to buy a different license for RadSpell.Net2.dll? Or it should be included in the installer that contains RadSpell.Net2.dll?

Any help on this much appreciated.

Thanks

SelectedValue is always empty

Hi,

I'm using a ListBox for selecting an item.
If a button of the control is clicked, I want to fetch the SelectedValue.
The SelectedItem is not null (since one item is selected) but all properties of the SelectedItem (which shoud be set, like Value, Text, ImageUrl) are empty. In fact, all Items of the ListBox don't have their information anymore.
I add the items only once (when the ListBox is initially created) - I simple create a List of RadListBoxItem and add them to the ListBox.

This is the code I use to create the ListBox:

m_listBox = new RadListBox();

m_listBox.ID = "ListBox1";

m_listBox.SelectionMode = ListBoxSelectionMode.Single;

if (!Initialized)

{

List<RadListBoxItem> items = LoadItems();

foreach (RadListBoxItem radListBoxItem in items)

{

m_listBox.Items.Add(radListBoxItem);

}

m_listBox.SelectedIndex = 0;

Initialized = true;

}

The Initialized property is saved in viewstate because my control isn't added when the page loads initially but later in a workflow.

This is how I create an item:

RadListBoxItem item = new RadListBoxItem(text, id.ToString(CultureInfo.InvariantCulture));

item.ImageUrl = "include/img/Objects/"" +imageUr;

items.Add(item);

All values are added correctly but in the PostBack they are empty.

What could cause this behavior?

Thanks!
