I am new to the telerik controls. I have looked at a bunch of examples but I cannot seem to get my panel bar to work. It just expands everything for both items and won't collapse. I'm sure it's something simple I just don't know what. Here is my aspx page.

How to use
foreach (GridDataItem dataItem in RadGrid1.MasterTableView.Items)
{
}
to get bound data value. if I have 2 columns of bound items, one it regular bound item - item1, the other is build in drop down item -item2(NOT template item). I need to get grid cell value in view mode, NOT edit mode.
or there are some other ways to loop the whole grid to get the bound data value?
Thanks,
Jessie

I need a grid that will display formatted text and hyperlinks. There are no issues getting the grid to populate on the server, but I'm having an issue getting client side databinding to work properly. There doesn't seem to be any problem with using a GridBoundColumn, that one gets updated as expected, but other column types I've tried (GridTemplateColumn and GridHyperLinkColumn) don't produce any results.
Here is the script that takes a json array of objects and updates the grid.
The json is something like [{JobCode:"Code1",JobDesc:"Desc1",Primary:1},{JobCode:"Code2",JobDesc:"Desc2",Primary:0}]
Here is the grid template.
This all works well unless I use a column other than the GridBoundColumn.
I've looked in the RadGridScripts.js file to try and figure this thing out.
For the GridTemplateColumn, it tries to fill in the grid using the _fillTemplateEditorsData function. This function is expecting to find some control or element in which to put the contents of the data. There are two searches performed:
var _301 = $telerik.findControl((cell != null) ? cell: row, _300);
and
var _304 = $telerik.findElement((cell != null) ? cell: row, _300);
In both cases, they return nothing, so the function just returns without having updated the cell contents with text.
I would really like to be able to control the grid on the client pc. Can somebody let me know what, if anything, I'm doing wrong and how I can manipulate the grid on the client using columns other than the GridBoundColumn.
I should mention that I'm using version 2009.1.311.35
Thank you

I have been developing a control, using Radgrid, which will get its list of columns and mappings from a database. We had previously done this using the Radgrid control, wrapped in a composite control, but there were several complications, the work arounds for which turned the control into a rather daunting piece of code. We also had many difficulties in getting the filtering to work properly with the dynamic databinding and the dynamic fields. The result of all this was a difficult to maintain code base, with no ability to do filtering (weren't using Linq at that time).
Since then, I have rewritten the control, removing much of the logic which was extraneous to the function of the grid, and made it to use databinding through Linq to an IEnumerable object. I had alot of success inheriting from Radgrid (which I know you don't officially support) and have followed the recommendations I could find as best I could. There's really only one issue now that I am having difficulty getting past, and I'm not really sure where to look.
When there is a postback from either the built in Radgrid sort or Paging, the very first record in the result gets duplicated when it is rendered. The dataset it is bound to has 100 records, yet it renders 101 records, with two occurances of the first record on the first page. If I do a postback using either of the other controls built in (like a custom checkbox column), then the first record is not duplicated. The same is true on consecutive searches, no duplicate record.
I was wondering if you had a hint as to where I can look to see the process of binding the datasource to the grid, or perhaps you have an idea as to what is differrent on a sort or paging event, as opposed to a CheckChanged event. The only thing I can see is that I am calling the Rebind method on the CheckChanged event (which is bubbled to the enclosing user control) and for the Radgrid Paging and Sorting postbacks it is calling CreateTableView and NeedDataSource. On CreateTableView, I am building a GridTableView object based on the configured columns in the database and returning this, and on the NeedDataSource I am pulling the datasource from the session (and have verified this contains only 100 records).
Any ideas would be appreciated.
Thanks,
Tyson Brown

I have a license for Telerik Asp.net Ajax UI controls. And when I downloaded the Telerik controls, I cannot see the folder for skins on my hard drive. I want to customize the skins for the Radgrid. Where can I get the .css files for the built-in skins for radgrid controls.
Thanks

1) The Office 2007 skin is being applied to our application via the web.config, but the MultiColumn comboBox we are creating does not seem to inherit the look and feel that the rest of the controls get (We are using an item template). How do we fix that?
2) How do you apply a Selected Value column to the MultiColumn example? We are using the item template, and have specified the DataValueField and DataTextField names in the declaration, is that all there is to it?
I am guessing that we don't use the id which we want to use for the selected value in the item template, and it will bind but be invisible to the user?

Folks,
Here is the Scenario.
I have a Master Page (Main.Master) and 2 Content Pages(Default & Default1.aspx). Master Page page has Company Header Logo and Other controls that are common to both .aspx Pages.. When I add both .aspx pages in the Project, I indicated Main.Master is their Master Page.
I have Link Buttons controls in Both Pages for Navigation Purposes. For Default.aspx Link1 Button On Click Event, Resonse.redirect("Default1.aspx") and Vice Versa.
My question is there any sample site or example in Radcontrols for Asp.Net Ajax to accomplish the Task? That will be appreciated.. I looked at Live Demos/Menu/Examples/Functionality/Templates/DefaultVB.aspx, tried to implement in Master Page. But the problem is that If I click the content pages Navigation Buttons, I loose my Master Page header contents (TEMPLATES logo in this example). I do not want to loose the header content of my Master Page, I want to retain them as I navigate between content pages. In the Past, I did this type of Job via SiteMapDataSource but I would like to implement from Telerik Rad Menu if possible..I am using RadControls for ASP.NET AJAX Q2 2009. Also any Telerik Tutorial will be Helpful.
Thanks
Ghulam

Hello,
We are using Q2 2009 and are noticing that our grid filter boxes do not display correctly in FireFox and the filter condition buttons sometimes do not display either.

Hi,
I am using master and content page in my application.
master page controls are radscriptmanager,radajaxmanger,
content page controls are radajaxproxymanager,radwindowmanager, radtabstrip and rad multipageview.
Windowmanager settings are
<telerik:RadWindowManager ID="rWindowManager" runat="server"
ClientCallBackFunction="CallBackData"
Left="" Skin="Vista" Top="" Behavior="Reload,Close" InitialBehavior="None" >
<Windows>
<telerik:RadWindow ID="rWindowUsersList" runat="server" Height="270px" Left="50px"
Modal="True" NavigateUrl="" ReloadOnShow="True" Title="Users List" Top="50px"
VisibleStatusbar="False" Width="280px"
OnClientClose
="DateWindowCancelClicked"
/>
</Windows>
</telerik:RadWindowManager>
When i open the radwindow on button click first time its work fine.
when i use javascript to do postback by using following method.
var ajaxManagerMaster = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>");
ajaxManagerMaster.ajaxRequest();
But when second time i open the window it is not opening with the proper size which are specified in radwindow.
It is also not calling the OnClientClose function specified in radwindow manager.
How can sovle this issue?
Thanks
