When we try to build our website in Visual Studio 2005, we get stopped with a bunch of errors that read something similar to:

Indirect reference is being made to assembly System.Web.Extensions version 3.5.0.0, which contains 'Telerik.Web.UI.RadDatePicker'. This Project references a prior version of System.Web.Extensions version 1.0.61025.0. To use 'Telerik.Web.UI.RadDatePicker', you must replace the reference to System.Web.Extensions with version 3.5.0.0 or higher.

Our application is in ASP.NET 2.0.

This is how it reads in the web.config:

<add assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />

How do we get this problem resolved so we can build this site?

Thanks in advance.

Menuitem selected persistent with highlightPath

Hi all,
I currently have a problem with the use of HighlightPath()
When I click on a item of my menu, it works good
When I click on a second item, it highlights too but the first is still highlited.

Here is a code sample :

Default.aspx :

<telerik:RadMenu ID="RadMenuClients" runat="server" >

<Items>

<telerik:RadMenuItem Text="Toto" Value="0" />

<telerik:RadMenuItem Text="Titi" Value="1" />

<telerik:RadMenuItem Text="Tata" Value="3" />

<telerik:RadMenuItem Text="Tutu" Value="2" />

<telerik:RadMenuItem Text="Tete" Value="4" />

</Items>

</telerik:RadMenu>

Default.aspx.vb :

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

'Highliting

Dim currentItem As RadMenuItem = RadMenuClients.Items.FindItemByValue(Session("idSel"))

If currentItem IsNot Nothing Then

currentItem.HighlightPath()

Else

RadMenuClients.Items.FindItemByValue(0).HighlightPath()

End If

End Sub

Protected Sub RadMenuClients_ItemClick(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadMenuEventArgs) Handles RadMenuClients.ItemClick

Session("idSel") = e.Item.Value

End Sub

Can you tell me what is wrong with my code ?

Thank You

Julien.

Root Item with No Child Item Border Issue

I have a RadMenu (with a custom skin - css code below) that has a root list with some of the root items having one level of child items. The issue that I have is that I have a border set to enclose the child items via a custom skin and it partially displays when you hover a root item that has no child items assigned to it (See attached images - NoChildItems.jpg and ChildItems.jpg). I changed the border color to red so that it would stand out during testing. Is there any way to rectify this or does the border have to be the same color as the root item background?

/* SVPD Menu / Simple> */

/* for root items */

div.RadMenu_SVPD ul.rmRootGroup

{

}

div.RadMenu_SVPD .rmLink

{

color: #ffffff;

padding-left: 15px;

font-family: Arial, Helvetica, sans-serif;

font-size: 12px;

font-weight: normal;

text-decoration: none;

height: 20px;

}

/* for hover, focused, expanded items */

div.RadMenu_SVPD .rmItem .rmLink:hover

{

color: #91c8ff;

cursor: pointer;

}

div.RadMenu_SVPD .rmItem .rmFocused,

div.RadMenu_SVPD .rmItem .rmSelected,

div.RadMenu_SVPD .rmItem .rmExpanded

{

}

/*for subitems */

div.RadMenu_SVPD .rmGroup

{

padding-top: 4px !important;

border: 1px solid #ff0000;

background: #003c77 url('Menu/rmVSprite.png') repeat-y;

}

div.RadMenu_SVPD .rmGroup .rmLink

{

color: #ffffff;

padding-right: 0px !important;

font-family: Arial, Helvetica, sans-serif;

font-size: 12px;

font-weight: normal;

text-decoration: none;

float: left;

}

div.RadMenu_SVPD .rmGroup .rmText

{

Padding-left: 10px !important;

}

/* for hover, focused, expanded items */

div.RadMenu_SVPD .rmGroup .rmItem .rmLink:hover

{

color: #91c8ff;

cursor: pointer;

}

div.RadMenu_SVPD .rmGroup .rmItem .rmFocused,

div.RadMenu_SVPD .rmGroup .rmItem .rmSelected,

div.RadMenu_SVPD .rmGroup .rmItem .rmExpanded

{

}

Radcaptcha on ajax page

I have some ajax stuff on the page- fill one dropdown based on another dropdown's selection.
I also used Radcaptcha, when submit the page, the page alway not valid, unless putting the radcaptcha inside the UpdatePanel .

<asp:UpdatePanel ID="UpdatePanel7" runat="server">
<ContentTemplate>
<telerik:RadCaptcha ID="RadCaptcha1" Runat="server" ValidationGroup="Group"
ErrorMessage="Page not valid. The code you entered is not valid.Page not valid. The code you entered is not valid"
ImageStorageLocation="Session">
</telerik:RadCaptcha>
</ContentTemplate>
</asp:UpdatePanel>

This will solve page not valid problem, but everytime when the ajax fired (first dropdown is selected), the Radcaptcha's text got changed. Is there anyway that can prevent the Radcaptcha text changing everytime when the ajax fired?

Thanks

Javascript Not Registering in Ajaxified Grid

Hi,

I have a RadGrid with a template column that uses a user control in the Edit Template. The user control tries to Register a script to run that has a function in it that will be called when the user clicks on the user control. However the function is not properly registered and cannot be called by the user control.

If I remove the RadGrid from the RadAjaxManager everything works fine.

Here is a link to a sample project (zipped) that demonstrates my problem: sample project.

I have looked around on the forums and tried some of the other suggestions to no avail.

Can you please suggest a workaround for this?

Thanks,
Oran

self-referencing hierarchy: binding data on client object

Hi,
I have created a RadGrid with self-referencing hierarchy without a problem. But as we are having some performance issues I don't have the luxure to send/receive big page sizes each time. So I send the grid empty without binding the data on needDataSource event. Then I get the data with ajax in json format which is quite small. The problem is I cannot find a client side event, which formats the data with the given hierarchical structure. Is there a way for that or do I need to write a custom javascript function to create that structure?

Where should I assign the filter expression on client side, which I do on server side like t.MasterTableView.FilterExpression = @"it[""PARENT""] = Convert.DBNull";

Given code creates the grid and binds the data but without a structure.

Thanks in advance,

Cem

Inconsistent Filter

I have a grid with a column for country and type along with many others.

By default the grid is ordered by country. When I click the letters in the pager at the bottom of the grid, it filters the country correctly.

Then I add a filter to the grid for type. Then I hide the filter and click the letters in the pager at the bottom of the grid. At sporadic times, it will still be filtered by type. Other times it will be filtered by country. What is happening here?

<input id="RadDock1_C_val1_ClientState" name="RadDock1_C_val1_ClientState" type="hidden" /></span>

And my javascript code - var test = $find("<%=RadDock1.ContentContainer.FindControl("val1").ClientID %>");
