Hi,

I need to remove an hyperlink look from my tree nodes. Tryed TreeNodeOver style like "text-decoration: none". However it is not working.

I used the below css code on aspx page:

.myNodeHoveredCss .rtIn
{
text-decoration: none !important;
}
.myNodeSelectedCss .rtIn
{
text-decoration: none !important;
}
</style>

Code behind used below line:
stNode.HoveredCssClass = "myNodeHoveredCss";

Can you please tell me how to remove Hyperlink look from tree node?.

Line: 8 Error: Object doesn't support this property or method

I am getting the following Javascript error:

Line: 8
Error: Object doesn't support this property or method

the following line of code is shown when debugging the code.

!v&&b.length>1&&d(b,"")>-1&&(j=RegExp(this.source,e.replace.call(c(this),"g","")),e.replace.call(a.slice(b.index),j,function(){for(var a=1;a<arguments.length-2;a++)arguments[a]===void 0&&(b[a]=void 0)

The javascript file that is purporting the error is in "itn.js".

I am getting this error when a Rad combo box is used as an editor for a column and when I click the drop down button to display the list of items within the drop down. Now I get the error only in IE Version 8.0.7601.17514 and not the other browsers. I checked to see if it was something in my code but its not. I am also receiving the error from your Demo site on the following page:

http://demos.telerik.com/aspnet-ajax/treelist/examples/columns/columntypes/defaultcs.aspx

it is on the second treelist control where the "Title Of Courtesy" contains a RadComboBox. Again when I click the drop down button on the control it throws the above javascript error. It never drops down the list of items on the control.

Any help on this I would greatly appreciate it.

Thanks

Problem with events

Hello,

I have a problem with my treeview events :

Normaly, the clickNode event is fired before the dataBound event.
But sometimes, it is the dataBound event which is fired before the clickNode.

Is there a solution to force clickNode first?

[Solved] Do RadControls all inherit from RadControl?

I want to be able to skin my Telerik RadControls on my asp.net page on the fly.
To do this I've made sure all these controls have an ID that starts "Rad" and when the page loads I have a method that cycles through all controls on a page and creates a List<Control> of those starting with "Rad".

Now all I need to do is cycle through my list and set the skin property to my selected skin. However, Control has no concept of "Skin" so I am trying to cast each of these to RadControl but am getting errors when casting, such as

Unable to cast object of type 'Telerik.Web.UI.RadPanelBar' to type 'Telerik.Web.UI.RadControl'.

My Code below...

protected void SetSkins(string colorScheme)

{

List<Control> RadControls = new List<Control>();

LoopControls(this.Page.Controls, ref RadControls);

foreach (Control c in RadControls)

{

((RadControl)c).Skin = colorScheme;

}

public void LoopControls(ControlCollection controls, ref List<Control> RadControls)

{

string output = string.Empty;

foreach (Control control in controls)

{

if (!string.IsNullOrEmpty(control.ID) && control.ID.StartsWith("Rad"))

{

RadControls.Add(control);

}

LoopControls(control.Controls, ref RadControls);

}

I suppose I could pass the skin name across and set the skin in the LoopControls method, but would still like an answer to my question.
