Hi, we are scratching our heads on how to set the time. The value in the database (StartTime) is

2011-07-22 07:00:00.000

and our dateTimePicker looks like this

 <telerik:RadDateTimePicker ID="RadDateTimePicker3" runat="server" Culture="English (United States)" DbSelectedDate='<%# Bind("StartTime") %>'  >
                                 <DateInput ID="DateInput3" runat="server" />
                                 </telerik:RadDateTimePicker>


But it always displays 12:00 AM in the time picker. I looked all over the support forums and there are many many examples for the timepicker itself, but nothing all that clear on raddateTimePicker. If anyone can help, that would be greatly appreciated. Thanks!

I'm trying to add fields to a RadFilter component, and I'm using this code:

	Telerik.Web.UI.RadFilterNumericFieldEditor testNum = new Telerik.Web.UI.RadFilterNumericFieldEditor();
        testNum.FieldName = "OrderID";
        testNum.DataType = Type.GetType("System.Int32");
 
        RadFilterQueryFilter.FieldEditors.Add(testNum);

However, when I execute, the field is not visible on the field list. What I am missing?

Hi,

while filtering a combox column within an item template, i received the following runtime error. This only happens on the radgrid combox column.

Microsoft JScript runtime

error: Sys.WebForms.PageRequestManagerServerErrorException: is neither a DataColumn nor a DataRelation for table DefaultView.

 

thanks,

I have a simple RadTagCloud on a page which has a relatively complex layout. The items in the tag cloud are the result of a query and clicking the item perform additional queries, some of which can take some time to complete. I want to show an Ajax loader image (rotating dots) inside the ProgressTemplate of a .NET UpdatePanel. The problem I have is that clicking the link cuased the page to postback rather than showing the updater image. To illustrate this point...

I have a simple button on the page which when clicked shows that AJAX is being implemented

 Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        System.Threading.Thread.Sleep(2000)
 End Sub

However, the RadTagCloud (AutoPostBack=true) control performs a post back and reloads the page

Private Sub cloudAttractions_ItemClick(sender As Object, e As Telerik.Web.UI.RadTagCloudEventArgs) Handles cloudAttractions.ItemClick
System.Threading.Thread.Sleep(2000)
End Sub

Is there a solution to this problem?

hi
I have a user control that is ajaxified by RadAjaxManagerProxy ,
I've also used a ToolTipManager that is ajaxified by setting it's OnAjaxUpdate property

It works well on page , but if I put this UserControl inside a ContentTemplate of a RadWindow in RadWindowManager
like this : 
    <telerik:RadWindowManager ID="RadWindowManager1" runat="server" EnableShadow="True"
        Skin="Office2010Blue">
        <Windows>
            <telerik:RadWindow ID="ContainerBrowser" runat="server" Title="Container Browser"
                Modal="true" Behaviors="Maximize,Close,Minimize,Move,Resize">
                <ContentTemplate>
                    <uc3:SkinBrowser ID="SkinBrowser1" runat="server" SkinType="Container" /> <<-- my user control
                </ContentTemplate>
            </telerik:RadWindow>
        </Windows>
    </telerik:RadWindowManager>

I get this error :

I really have no idea to fix this problem
Thank you very much for your help

I am using a RadDateTime Picker and different controls like dropdown list etc on a ASP.Net web user control, And  I have RadAjaxLoadingPanel and RadAjaxPanel in my ASP.Net page.
Now when any event gets fired from any controls of the user control, it does display a loading panel in the main page; although the events fire properly and the page is updated.
The problem causing is that the loading panel not displaying only when the RadDateTime Picker selected the first time, Once we selected a date and try to change the selected date this time the loading panel works properly.
Note that the usercontrols are not added dynamically, they exist when the page is loaded.
Can anyone please guide me with an alternative way of achieving this? Or if I am missing something? I am not using AjaxManager in the ASP.net page.

Recently, we updated Telerik library from Q2 2010 to Q2 2011 and everything was good except the sliders i.e. pagers and only in all versions of IE (see attachments). Firefox and Chrome do not have the problem. Is there any idea how to fix that?

Thanks.

Please, I need your help,
