NestedViewTemplate with HierarchyLoadMode="ServerOnDemand"

Hello,

I have a grid with NestedViewTemplate and even though the parent MasterTableViews HierarchyLoadMode is set to "ServerOnDemand", it behaves like if it was "ServerSide".

For the following (simplified) code:

<

MasterTableView autogeneratecolumns="False" datakeynames="IdCustomer"

datasourceid="ObjectDataSource1" HierarchyLoadMode="ServerOnDemand">

<legend style="padding:5px;"><b>Details:</b>

</legend>

<asp:HiddenField ID="ctl_hiddenId" runat="server" Value='<%# Eval("IdCustomer") %>' />

<asp:ObjectDataSource

ID="ctl_DetailObjectDataSource" runat="server" SelectMethod="GetDetail"

TypeName="DataModel.DetailDataSource">

<asp:ControlParameter ControlID="ctl_hiddenId" DefaultValue="" Name="IdCustomer"

PropertyName="Value" Type="String" />

</SelectParameters>

</asp:ObjectDataSource>

<tr>

<td>

//something here

</td>

<td>

</td>

</tr>

<tr>

<asp:ListView ID="ctl_photoListView" runat="server" DataSourceID="ctl_DetailsObjectDataSource">

<asp:PlaceHolder ID="itemPlaceholder" runat="server"></asp:PlaceHolder>

</ul>

</LayoutTemplate>

<li>

//something here

</li>

</ItemTemplate>

</asp:ListView>

</td>

</tr>

<tr>

//

</td>

</tr>

</table>

</fieldset>

</NestedViewTemplate>
//columns

</

MasterTableView>

It calls the GetDetail method for each row on the initial loading of whole grid (the method is called two times for each row in grid - could it be somehow set to be colled just once), and then on expanding nested template there is no more calling of this metode of the object data source.
I need to call selecting method of my object data source only when expanding nested template - is there something else that I need to set?

Thank you
Jan

RadUpload outside UpdatePanel doesn't show ProgressArea

Hi,
i've a page that contains a RadUpload control and some other controls that are contained in an UpdatePanel. I underline that RadUpload IS NOT inside the UpdatePanel.

Now i select the file to be uploaded, then I do an async postback changing on of the controls in the UpdatePanel. RadUpload correctly doesn't loose selected file and upload doesn't automatically start.
Than I click on a submit button (outside UpdatePanel) to do a normal Postback. Upload is correctly performed BUT... progress area doesn't appear.

Is that normal? Is there some kind of workaround?

Thanks,
Marco

Many Grids + Many Pages = Config Nightmare?

Pretty simple question and I'm sure there's a good solution for this: I want to keep my UI very consistent. I'm going to have lots of pages that make use of the RadGrid control. What I want to avoid is having to re-create the default properties, i.e - setting page size, allow sorting, skin, etc, etc.

I'm guessing I would create some kind of wrapper for the Grid control and set its default values there. Then instead of using <telerik:RadGrid... I can use <customtelerik:RadGrid... that uses my default settings. Of course, I would want the ability to override those in the specific pages if I have to.

Any ideas?

RadEditor Paste functions and shortcuts not working in IE7

Hi there,

I am experiencing a problem with the RadEditor for ASP.Net AJAX. When I'm trying to paste content into my Radeditor on my page, IE7 causes 100% cpu usage and hangs. I have to use CTRL+ALT+DELETE to shut down IE. This is on my development machine. I use the standard RadEditor, all tools enabled. This problem occurs only in IE7, and not in other browsers. I do not get any errormessage's or whatsoever. The version I'm using is Q1 2009 (which I just downloaded, and I upgraded from Q3 2008, which had the same problem).

So I'm wondering what I should do to resolve this?
This is the code in my .ascx webcontrol:

<telerik:RadEditor id="rteTekst" Width="640px" Height="300px" Runat="server" DialogHandlerUrl="~/Telerik.Web.UI.DialogHandler.axd"></telerik:RadEditor>

Regards,
Thomas Schepers

problems using asp.net client side javascript functions for the validators

This is a problem using the javascript functions of the asp.net validators on the client with the rad editor.

I did not have problems when I was using the validators on a page but when i want to do validation on the client using the client side javascript function of the asp.net validators I get this error:

the validator always is triggered and fails the validation even thought there is some text in the editor. But if I put an <img></img> tag then it passes the validation:

for example this does not validate:

iuyuy<br />
qqwwq<br />
<br />
<span style="color: #ff0000">qwwqe</span><br />

but this does validate:

iuyuy<br />
qqwwq<br />
<br />
<span style="color: #ff0000">qwwqe</span><br /><img></img>

this small example reproduces the problem:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default43.aspx.vb" Inherits="Default43" %>

RadGrid GroupHeaderItemStyle issue with Ajax

I have created a grid using GroupByExpressions.
I have set the GroupHeaderItemStyle font-size to medium.

<GroupHeaderItemStyle Font-Size=Medium />

The grid contains a template colmun having asp dropdownlist with autopostbask=true. when the dropdownlist value is changed i am rebindingg the grid using RadAjax.

The problem is that when the grid is rebinded using RadAjax the GroupHeaderItemStyle font-size=medium property not works.

If i rebind the grid without using the RadAjax it works properly.

Thanks.

class="combo-item-template" which is in 2009 not available in Q32008.

Hi,

I have used multiselect items in combobox as shown in Q1 2009(ComboBox -> Functionality -> Templates). In that i have seen as:

When i use this in my project which is currently using Q3 2008, giving a message called "css class not found". I think this class is only included in 2009. Can i use this in 2008 by adding any references in my project? If it can be used please tell how to add references.

Thanks,

Multiple Rotators sample

Hi there,

I can see in the RadRotator For ASP.NET AJAX's Multiple Rotators sample (URL : http://demos.telerik.com/aspnet-ajax/rotator/examples/multiplescroller/defaultcs.aspx) two differences with the RadRotator For ASP.NET's sample (URL : http://demos.telerik.com/aspnet/rotator/examples/functionality/MultipleScroller/DefaultCS.aspx).

First, in the way the scroll is performed. With RadRotator For ASP.NET, scroll does not stop. I would like to reproduce this behavior with the RadRotator For ASP.NET AJAX, is it possible? If not, why?
An other difference with the font anti-aliasing under IE7. There is a thread about it and I saw that we can "fix it" by changing the CSS bakground color. But after this change, font is not really smooth as it is under FF for example. I guess that opacity filter used in the fade out FX is the key. It would be great that Telerik developers reconsider this issue. In enterprise environment, where IE is really present, it is a pity to see such a regression!

Thanks.

Best regards,

Damien
