I would like to display real-time message from database on top of main page in my project so that I can view it anytime when I navigate other webpages. I manage to bind the updated message in dataset but the RadTicker is missing from the page. Below is the workaround that I have done in my project.

 

Currently, I'm using RadAjaxTimer to trigger RadTicker to update the message when there is any new message added into database. I created these 2 controls and script manager in ascx page as global user controls in my project. Then, I'll call these reference controls in a RadAjaxPanel on the main page and bind the updated message in RadTicker on ascx page Page_Load event and RadAjaxTimer_Tick event. I only see AjaxLoadingPanel displays during data binding and the RadTicker is missing from the main page after it is done. What happens to the RadTicker? Does it cause by System.Threading.Thread.Sleep(5000) that I configured in RadAjaxTimer_Tick event? Is it used to control the AjaxLoadingPanel display time?

 

 

Below is the ascx page that I created in my project.

Please advice if I have done anything wrong in the coding. I need a solution urgently. I appreciate if you may provide a sample project for me. Thank you.

I am trying to change change axis, chart title and points from client side but i can't able to  find any properties for this from client side. Is this possible to change these values from client side?

Hi.

I've developed a page with a RadGrid, sourced by a List of POCO's, using an EditFormType of WebUserControl.  My user control handles the DataBinding event (attaching to it in the control's Page_Load(), if that's important).  I click my edit button in the grid... the control pops up, mostly with populated data.  I seem to at least be doing something right...

The one input in the user control I can't seem to get populated is the drop-down, which I've tried implementing as both a plain old ASP.NET DropDownList or a RadComboBox.  If I debug and step through my DataBinding handler.  I can see that it's been properly selected.  But sometime between the end of the DataBinding() call and rendering, the list has lost its selection, and renders showing the first item in the dropdown.

The grid itself is inside a RadAjaxPanel, but I it doesn't appear to be an ajax issue because the problem persists when I set the panel's EnableAjax=false.

All I'm doing to select an item is:


The function that databinds the list itself checks the item-count of the list, and skips the data binding if there are already items.  So it's not losing the selection due to an extra bind.

If I just throw this control on a blank page and call SelectBU() from the .aspx codebehind, it works fine.

I'm on 2014.1.225.40 in ASP.NET 4.0, and I'm targeting IE9 primarily.  (I've seen this same behavior in the versions of Chrome and Firefox I have installed on my box.)

Thanks for any guidance anyone can provide.

I'm using OLAP connection to pivot grid. I have noticed that all of my attributes in dimensions are listed in "more fields" group. i don't want that grouping. (excel it doesn't group that way)

Yohan

I am using this code:


inside a .ascx file and I keep getting the 'The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>) ' error.  Any suggestion on how to fix this?

Hi,

I updated my RadTabStrip and RadMultiPage controls ajax manager per this - http://demos.telerik.com/aspnet-ajax/tabstrip/examples/application-scenarios/ajax-enabled-tabstrip-and-multipage/defaultcs.aspx

But now on one of the .ascx pages where I have several Ajaxified RadGrids the controls in the grid won't post? The ajaxmanager on the page is question looks like this:
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
        <AjaxSettings>
             <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">  
                    <UpdatedControls>  
                        <telerik:AjaxUpdatedControl ControlID="RadGrid1" />  
                                <telerik:AjaxUpdatedControl ControlID="RadGrid3" />  
                                <telerik:AjaxUpdatedControl ControlID="RadGrid4" />  
                    </UpdatedControls>  
                </telerik:AjaxSetting>  
            <telerik:AjaxSetting AjaxControlID="RadGrid4">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadWindow1" />
                    <telerik:AjaxUpdatedControl ControlID="RadWindow2" />
                    <telerik:AjaxUpdatedControl ControlID="RadGrid3" UpdatePanelCssClass="" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="RadGrid2">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadWindow2" />
                    <telerik:AjaxUpdatedControl ControlID="Label1" UpdatePanelCssClass="" />
                    <telerik:AjaxUpdatedControl ControlID="RadGrid2" />
                    <telerik:AjaxUpdatedControl ControlID="RadGrid1" UpdatePanelCssClass="" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="RadGrid1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadGrid2" UpdatePanelCssClass="" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>

Dear All,

I've been struggling to make RadGrid work with UseStaticHeaders and FrozenColumnsCount properties set. It was working yesterday before we introduced any client-side functionality and today we realized that it wasn't working correctly.

With hours of research in Google, we were not able to find any remedy for the behaviour.

Issue
Column headers won't scroll horizontally in RadGrid although following parameters are set :
AllowScroll="true" SaveScrollPosition="true" UseStaticHeaders="true" FrozenColumnsCount="1"

Remedy
During our development, we have assigned grid's ClientIDMode="Static". Having a static ClientID was the cause of this wierd problem. Once removed, horizontal scrolling was back to normal (as well as frozen columns).

Maybe it will help someone with similar issue.

Kind Regards,

OZAN GUNCELER

Hi,

For this:


On firing, OnItemDataBound, this works:


But this does not (Label is null):


I can't see the wood for the trees, I think. Why can't I get a reference to the label?

Thanks,
