Hi,

I am dynamically creating a bar chart from a data table object and I am having an issue with the X-Axis labels. The longer x-axis value labels are running horizontally across the chart and laying over the next column's label. My solution to this problem was to remove all but the first 10 characters of the label value, but I was wondering if there is a way to wrap the label so it does not flow over the next column's label.

Thanks,
Ryan A.

not working

Hi
I developed an app that use RadUpload and RadUploadManager.

I installed on my server but I receive this error:

RadUpload Ajax callback error. Source url returned invalid content:

System.NullReferenceException: Riferimento a un oggetto non impostato su un'istanza di oggetto.
in Telerik.Web.UI.RadProgressContext.Serialize(TextWriter writer)
in Telerik.Web.UI.RadUploadProgressHandler.ProcessRequest(HttpContext context)

Telerik.RadUploadProgressHandler.ashx?RadUrid=e7e077e5-c37c-4ef6-91f7-642686f3f06f

Did you register the RadUploadProgressHandler in web.config?

Please, see the help for more details: RadUpload for ASP.NET Ajax - Configuration - RadUploadProgressHandler.

Please help

Can't set Skin property in Medium Trust

I just switched my website over to Medium Trust to check if there were any issues, and I got a pretty nasty exception which I traced to my setting the Skin property on some RadChart instances. The partial stack trace follows:

Telerik.Charting.Styles.SkinnablePropertyAttribute..ctor() ---> System.MethodAccessException: Telerik.Charting.Styles.SkinnablePropertyAttribute..ctor() ---> System.Security.SecurityException: Request failed. at System.Security.CodeAccessSecurityEngine.ThrowSecurityException(Assembly asm, PermissionSet granted, PermissionSet refused, RuntimeMethodHandle rmh, SecurityAction action, Object demand, IPermission permThatFailed) at System.Security.CodeAccessSecurityEngine.ThrowSecurityException(Object assemblyOrString, PermissionSet granted, PermissionSet refused, RuntimeMethodHandle rmh, SecurityAction action, Object demand, IPermission permThatFailed) at System.Security.CodeAccessSecurityEngine.CheckSetHelper(PermissionSet grants, PermissionSet refused, PermissionSet demands, RuntimeMethodHandle rmh, Object assemblyOrString, SecurityAction action, Boolean throwException) at System.Security.PermissionSetTriple.CheckSetDemand(PermissionSet demandSet, PermissionSet& alteredDemandset, RuntimeMethodHandle rmh) at System.Security.PermissionListSet.CheckSetDemand(PermissionSet pset, RuntimeMethodHandle rmh) at System.Security.PermissionListSet.DemandFlagsOrGrantSet(Int32 flags, PermissionSet grantSet) at System.Threading.CompressedStack.DemandFlagsOrGrantSet(Int32 flags, PermissionSet grantSet) at System.Security.CodeAccessSecurityEngine.ReflectionTargetDemandHelper(Int32 permission, PermissionSet targetGrant, CompressedStack securityContext) at System.Security.CodeAccessSecurityEngine.ReflectionTargetDemandHelper(Int32 permission, PermissionSet targetGrant) The action that failed was: Demand The type of the first permission that failed was: System.Security.PermissionSet --- End of inner exception stack trace --- at System.Reflection.MethodBase.PerformSecurityCheck(Object obj, RuntimeMethodHandle method, IntPtr parent, UInt32 invocationFlags) at System.Reflection.RuntimeConstructorInfo.Invoke(BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture) at System.ComponentModel.AttributeCollection.GetDefaultAttribute(Type attributeType) at System.ComponentModel.AttributeCollection.get_Item(Type attributeType) at Telerik.Charting.Styles.StyleSerializer.Deserialize(XmlElement rootElement, Object styleContainer) at Telerik.Charting.Styles.StyleSerializer.DeserializeProperty(PropertyDescriptor propDescriptor, XmlElement propElement, Object styleContainer) at Telerik.Charting.Styles.StyleSerializer.Deserialize(XmlElement rootElement, Object styleContainer) at Telerik.Charting.Styles.StyleSerializer.DeserializeProperty(PropertyDescriptor propDescriptor, XmlElement propElement, Object styleContainer) at Telerik.Charting.Styles.StyleSerializer.Deserialize(XmlElement rootElement, Object styleContainer) at Telerik.Charting.Styles.StyleSerializer.DeserializeProperty(PropertyDescriptor propDescriptor, XmlElement propElement, Object styleContainer) at Telerik.Charting.Styles.StyleSerializer.Deserialize(XmlElement rootElement, Object styleContainer) at Telerik.Charting.Chart.LoadSkin(Object skinContainer, TextWriter text) at Telerik.Charting.Chart.ApplySkin(String skinName) at Telerik.Charting.Chart.set_Skin(String value)

If I removed the Skin="Telerik" from the markup, it works fine. If I run the site in Full Trust, it works fine. Is this a known issue, are there any workarounds or fixes?

Thanks,

RadComboBox Forcing results to scroll down

Hello,
Had a quick question on results box for the RadComboBox.

Depending on CSS setup, and position of combobox relative to the page, the results for combobox can show up above or below the main input field. Is there a way to force the results to always show up so that they are underneath the combobox instead of above it or below it depending on CSS and position of the page?

No drag preview

Hello

I am building dynamic docks containing an image which is also the handle for the dragging of the item... but when I drag the image, I'm not getting the semi-transparent preview of the image to show what I am dragging, and the target zone isn't showing a highlighted outline.

I've looked through the examples, but I can't see where I am going wrong... what do I need to do?

Many thanks

Darren

Hide toggle image button of Root node on page load

I'm using RAD Treeview Q2 2008. Please give me an idea or better yet sample code on how to hide the toggle image button of the root node on page load. I tried doing the suggestions in the following thread

http://www.telerik.com/community/forums/thread/b311D-bebhgk.aspx

but wasn't able to accomplish what I want as $find("<%=RadTreeView1.ClientID%>") is always null on page load, either using ScriptManager.RegisterStartupScript() or by including the script on client-side page. I'm generating the nodes server-side with the root node automatically expand and disabled, thus end-users cannot toggle the node.

Thanks in advance.

New feature request: 1px border

Hi,
I just want to re-iterate that the editor currently does not support having a single pixel wide (plain) border (to mimic a text area). I need this along with the ability to use the "Show on focus" toolbar mode in order to fit the editor on existing complex ASPX input forms.

I have implemented a 'dirty javascript hack' to make this work but I would really appreciate this simple style be supported natively by the editor.

Thanks, Andy
