Hi,

A. I bound a radGrid control to a custom collection called FactoryList(of Tkey).
B. The FactoryList control derived from BindingList (of Tkey) and implements ITypedList as follow:
    1. The GetItemProperties return a collection of ColumnPropertyDescriptor objects, each is derived from PropertyDescriptor class
    2. The ColumnPropertyDescriptor class exposes information based on DataColumn meta-data i.e. ColumnName, ColumnType, and also handle SetValue and Get Value methods.
 
C. A FactoryList instance contains objects that are derived from a base class called BaseEntity. The BaseEntity class implements

ICustomTypeDescriptor, where the GetItemProperties retruns a collection of ColumnPropertyDescriptor same as the FactoryList class does.
D. I use the NeedDataSource event to bind the FactoryList to the radGrid  

All works fine, till I sort the grid rows by clicking on one of the grid column headers. In that case I got the following error:

No property or field 'LST_NAME' exists in type 'Object'  

 -  'LST_NAME' is one the columns I was trying to sort

I have tabstrip/multipage. pageviews are filled from user controls. I need to input some data (like first/last name) on the first pageview and then show this value on other pageviews.
server-side assigning is absolutely not appropriate as I have page already rendered when I start my input with the first tab clicked.
So I decided to change variables with jQuery on client-side when the tab is clicked.
But My Jquery cannot find the classes (and variables) from the pageviews.

When I take a look at page source I see that there is only first pageview. I assume that others are rendered dynamically.

Can you please advice me the best technique how I can change the variables with the same names and same classes on all my pageviews?

I tried the option to render page "OnDemand", but it didn't help.

Hi, I am using a browser add-on called httpwatch which allows me to see network traffic while I upload a document, I notice when i am uploading I get a lot of HTTP 401 unauthorized errors which should not happen since I am an authenticated user, then imeadiately I get code 200 which indicates OK, I get this every few hundred bytes until the upload completes.  Can anyone explain what is happening here, I am executing some server side processing on the files in UploadedFiles collection so the Target property is not set.  The site does have windows authentication turned ON but again I am a authenticated user.  Is there any permissions needed to be applied because I am doing server-side processing.  I am using 2009 Q2 build 826.35.  Most of the 401 errors come from the RadUploadProgressHandler.ashx issuing GET requests.

Thanks Kerry

The parent Grid displays Committee Name for example student committee. When I click on the student committee it loads the rad grid inside the nested view template that displays me the names of the student associated to that committee.

If there aren't any students for that committee it should display the message from no records template.

My questions are:

When the I call the child rad grid from the nested view template it does not display message from the no record template.
Secondly if there is data it does not display data either on the child grid.
But when I click the add button on the child rad grid it fires the NeedDataSource Event on the Child grid and displays the no records template message or displays student data then!

Can you please tell me how do I handle this, since after I  click the committee name it should call the need data source event on child but it isn't doing that for some reason can you kindly let me know about it.

Thanks and Regards

I have an ASP.NET 2.0 web application that was using RadAjaxManager and RadComboBox from Q3 2007. I recently upgraded those controls to the Q3 2008 version. The only code I had to change was with the Ajax components, which is why I put most post here and not in the combobox forum. I think my problem is an interaction with the updated Ajax components.

My problem is with a few RadComboBoxes. I had developed them as multi-select containing checkboxes. After the upgrade, the checkboxes appear, but the text of the checkbox item does not.

Here is the relavent page code and javascript that is attached to the RadComboBoxes. Thanks.

I have upgraded from RADcontrols 2006 to 2009.  The below code that used to work is no more working.  This code is for treeview in a combobox. once a node item is selected it supposed to be the show up on the radcombobox text. I am able to populate and navigate through treeview items but when a node is selected, the item is not being displayed as the selected item in combobox.

 <div onmousedown="allowCBClose(true);">
                    <radC:RadComboBox ID="ddlHierachy" runat="server" RadControlsDir="~/Resources/" Skin="WindowsGray"
                        SkinsPath="~/Resources/Skin/RadControls/ComboBox/Skins" Height="200px" NoWrap="True"
                        Width="80%" OnClientDropDownClosing="OnClientDropDownClosing" AllowCustomText="true"
                        EnableLoadOnDemand="true" OnItemsRequested="ItemsRequested" OnClientItemsRequested="OnClientItemsRequested"
                        OnClientKeyPressing="keypressing">
                        <ItemTemplate>
                            <div onmouseup="allowCBClose(false);">
                                <radT:RadTreeView ID="rtEventCycle" runat="server" BeforeClientClick="ProcessClientClick"
                                    AfterClientClick="ProcessClientClick">
                                </radT:RadTreeView>
                            </div>
                        </ItemTemplate>
                    </radC:RadComboBox>
                </div>
Can some one help me upgrade the code to the newer version of radcontrols in 2009. I changed radC to telerik. But it doesn't work and then it says BeforeClientClick and AfterClientClick are no more valid.

Hello,

What I am trying to do is to have only one visible Upload at a time, selecting a file will result in hiding it and creating a new clean one - we are not actually hiding it, we are displaying it in a different GUI.

How can i do that? both client side and serverside (if ajax is used).

Hello,

I'm using a RadGrid like a listbox, with a ClientSelectColumn so the selection of the items cam be handled client side. I have enabled client selection and multi row selection. These work fine if the checkbox is the item clicked. If I select multiple items by clicking on the checkbox in the ClientSelectColumn and then select another row by clicking outside of the checkbox, the row I clicked in is selected and the checkbox for that row is checked, but all of the previously checked items are now unchecked. Why are the previously selected rows unselected when the row itself is clicked?

Thanks,
Casey

Hello,

I'm trying to use a RadEditor inside a Popup that is coming from a RadGrid. This is a part of my code:


The problem is that in Firefox, after reloading the page the RadEditor becomes disabled and loses it's text. This only happens in Firefox, in IE it works great.

Anyone know why this is happening?

Thanks,
Michael
