RadListView events not firing in user control

Hi,

I need to build a photograph competition page that has a RadTabStrip which I add tabs to for each competition. Each tab contains a user control, that has a RadListView to view the member's entries and two buttons, for uploading and deleting entries.

I am having difficulty with the ItemDataBound & NeedDataSource events in the RadListView. I am not sure what to do and would appreciate it if someone could steer me in the right direction.

Kind regards,
Pierre

Check box is not unchecking in grid in .NET 4.0 framework

Hi,

I am facing an issue with our application, the checkbox inside the Telerik Radgrid in our application is not unchecking when it is clicked first time (as per the business logic the grid will be loaded as few rows checked. And this issue occurring only in this scenario). But it is unchecking on the second time clicked. This issue we got after migrating the application from .Net 3.5 to 4.0.

In our 3.5 application grid is working fine in the above said scenario. we have tried with 4.0 Telerik and Spring DLL ‘s, still we are facing the same issue.

Please suggest us on what we can do to rectify the Telerik Control issue.

Skin for ItemTemplate in RadComboBox

Hello,

I used the following code to generate items inside a RadComboBox

<telerik:RadComboBox ID="SearchComboBox" runat="server" Skin="Office2007">

<ItemTemplate>

<%# DataBinder.Eval(Container.DataItem,"Name") %>

</ItemTemplate>

</telerik:RadComboBox>

SearchComboBox.DataSource = dataTable;

SearchComboBox.DataTextField = "Name";

SearchComboBox.DataValueField = "ID";

SearchComboBox.DataBind();

My problem is it seems that any items inside the <ItemTemplate> tag does not inherit or use the css styles defined on RadComboBox's Skin attribute. The items are generated but there's no background color changes (onmouseover) on the items.

is there a way for the items to be able to use the defined skin?

Thanks

Filtering Radlistbox items with radio buttons

Hi there I have a list box filled with a list of course names. If a course is assigned to you then it will have a green colour block before the name, if its not assigned to you it will appear with a red block before the name. I have three radio buttons one called "All", another called "Assigned", and the last one called "Not Assigned". Is it possible when selecting assigned that the green ones will just appear and when selecting not assigned only the red ones will appear? I've tried adding the radio button code into the page load but editing the lists like this removes the items forever for example when I click on assigned it removed the red items for the remainder of that session. What is the best way to do this?

Thanks, James

Could not load file or assembly "Telerik web.ui"

Hi,

I downloaded the telerik suite of controls from the below location: RadControls for ASP.NET AJAX Q3 2012
http://www.telerik.com/products/aspnet-ajax/download.aspx

I have checked this site: http://www.telerik.com/help/aspnet-ajax/moss-deploying-radcontrols.html

I am using SharePoint 2010 and trying to use the RAD Grid. I created a visual web part and added the radgrid and bound the controls.
I have the Telerik.web.ui (version 2012.3.1016.35), Telerik.Web.Design (version 2012.3.1016.35) in GAC. I have added the safecontrols as below:

<SafeControl Assembly="Telerik.Web.UI, Version=2012.3.1016.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" Namespace="Telerik.Web.UI" TypeName="*" Safe="True" />

<SafeControl Assembly="Telerik.Web.UI, Version=2012.3.1016.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" Namespace="Telerik.Web.Design" TypeName="*" Safe="True" />

I have both the dll's added in 14 bin and in the bin of the website.
I am getting the error as "could not load file or assembly Telerik.web.ui Version 2011.2.712.20,culture=neutral,PublicKeyToken=121fae78165ba3d4 . The located assembly's manifest location does not match the assembly reference.

How to fix this?
Thanks

[Solved] How to edit radcombobox item attribute at client side?

I have a combobox as follows:

<telerik:RadComboBox ID="ddlDevelopmentArea" runat="server" Width="200px" DropDownWidth="220px"

EmptyMessage="" HighlightTemplatedItems="true" OnClientSelectedIndexChanged="OnClientSelectedIndexChangedEventHandler">

<HeaderTemplate>

<table style="width: 240px" cellspacing="0" cellpadding="0">

<tr>

<td style="width: 150px;">

<asp:Label runat="server">

<%=AutismPro.Classroom.SR.GetString("Curriculum", "Curriculum_DesignCurriculum_DevelopmentAreaCombo_Header")%>

</asp:Label>

</td>

<td style="width: 90px;">

<%=AutismPro.Classroom.SR.GetString("Curriculum", "Curriculum_DesignCurriculum_DevelopmentAreaCombo_HasGoals")%>

</td>

</tr>

</table>

</HeaderTemplate>

<ItemTemplate>

<table style="width: 210px" cellspacing="0" cellpadding="0">

<tr>

<td style="width: 150px;">

<%# DataBinder.Eval(Container, "Text")%>

</td>

<td style="width: 60px;">

<%# DataBinder.Eval(Container, "Attributes['HasGoals']")%>

</table>

</ItemTemplate>

</telerik:RadComboBox>

I would like to change the value of an attribute at client side. Following is my code try:

var combo = $find("<%= ddlDevelopmentArea.ClientID %>");

combo.trackChanges();

combo.get_selectedItem().get_attributes().setAttribute("HasGoals", "False");

combo.commitChanges();

The value gets changed in combo object but is not reflecting in UI/HTML.

Please help.

Thanks in advance.
