Telerik.Web.UI.dll issue with vs2008

[ankammarao]

Hi,

I am trying to use

Telerik.Web.UI.dll (with version 2007.2.1107.0) in my vs 2008 project, I made proper settings inside my web.config, and registered with in my aspx page,

I am using RadTreeView', RadGrid' controls inside my aspx page


Registering the Telerik.Web.UI on top of my aspx page like below

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

and my aspx page will have rad controls like

1) <telerik:RadGrid runat="server" ID="RadGrid1" AutoGenerateColumns="False" GridLines="None"

 

Skin="Windows7" OnItemDataBound="RadGrid1_ItemDataBound" OnDeleteCommand="onDelete1"

 

Height="100%" Width="80%">

2)

<telerik:RadTreeView ID="RadTreeView1" runat="server" EnableDragAndDrop="True" OnNodeDrop="RadTreeView1_HandleDrop"

 

OnClientNodeDropping="onNodeDropping" OnClientNodeDragging="onNodeDragging" MultipleSelect="True"

 

EnableDragAndDropBetweenNodes="True" EnableEmbeddedSkins="true" EnableTheming ="true">

but when i try to build the my  asp.net website I am getting the below errors
1) Unknown server tag 'telerik:RadTreeView'
2)Unknown server tag 'telerik:RadGrid'

Can any one please help me out how to resolve the issue. both my aspx and code behind pages are not recognising the the teleric controls

Hello ankammarao,

Please confirm that Telerik assembly is not missing from the references. Try to re-add it. In the solution explorer, right-click on your website(or your web application). Then select on "Add Reference", and add the Telerik.Web.UI.dll

All the best,

Teleric.Web.UI.DLL(Ver 2007.2.1107.0) does not provide the

 

RadGrid and

 

RadTreeView controls

Can anyone please share any idea how to get higher version of Teleric.Web.UI.DLL (2007) which will support the radgrid and radtreeview controls but not Teleric.Web.UI.DLL (2010), because I am going to use radgrid and radtreeview inside my vs2008 version

Hello ankammarao,

You can install the recent RadControls for ASP.NEt AJAX version, and use the controls in VS2008.
If your target framework is .Net 3.5, you can use the Telerik.Web.UI.dll labeled 2010.2.929.35.

Kind regards,

I am aslo having same problem. I am using 2009.3.1103.35 and .Net 3.5.

The RadTreeList controls are not loaded. The error displays  Unknown server tag .

Thanks

Hi Vigneshwaran,

Please install the latest RadControls for ASP.NET AJAX version (2010.3.1109.35). Back in 2009 the RadTreeList was not written yet.

Best wishes,
