radgrid master-detail with full editing

Hi all,

I have a grid with a sub grid. All works wel, except the detail grid will not insert, update or delete. I can select edit, I'm getting a popup edit, but when I click update, the record is not being updated. No errors. The event "ItemCommand" triggers, and thats it! nothing else, no other events, not from the grid as the datasource.

I've tried (among other 1000 things) to use the detail datasource on a single grid, and there are no problems.

In the example:
http://demos.telerik.com/aspnet/prometheus/Grid/Examples/DataEditing/ThreeLevel/DefaultVB.aspx

it seems a piece of cake... I've copied all the properties edc.. It is costing mne hours and still nothing...

do I need to set other properties? Is detail editing not supported this way?

Access GridRatingColumn with Javascript

I have a GridRating column in my RadGrid. My Grid is populated by Javascript at run time and there is no design time or code behind databinding. Is there a way the Rating column can be accessed at javascript level in OnRowDataBound method and the value set for the same?

Thanks

Telerik.Web.UI Version upgrade Compatibility issue

Hello team Telerik,

I am using your trial version and planning to renew my licence but i am facing some compatibility issues after using the trial version.
My Previous Version of Telerik.Web.UI.dll = 2008 3.1314.20
Version of trial Telerik.Web.UI.dll = 2014.2.724.40

Now the problem is that in my previous dll i am using skins like 'default2006' , 'skyblue' etc etc for my controls and those were working fine but as i updated the trial version dll in my project i am getting the error regarding these skins because these are not in the new version. Are your components not backward compatible?
if not then how can i fix the error that i am getting (by changing the previous skins with the new one on every screen?)

Secondly, I have used some custom skins while i was using the previous version of dll but as i updated the trail version the custom skins are not working also?
my second question is that does newer version supports custom control skins? if yes the Give me an example where a custom skin is used on a control.

My third question is that What EnableEmbeddedskins do? and keeping in mind the above two scenarios how can i use it?
(i have seen a post where u people have suggested to disable it in web.config and then enabled it for only specific screen where control is using SKIN.is it the only way to use it? going on every screen with skin attribute in it and EnableEmbededSkins= true for that control? ) Please give me an early response so that i can buy the licence as soon as possible...

</div>

I want to udpade or add new records using C# code behind. However I cannot get access to any of the controls. When thew code attemps to read the value of the value of the control, in this case a textbox, I get an error message stating {"Object reference not set to an instance of an object."} here is the code

protected void RadGrid1_UpdateCommand(object sender, GridCommandEventArgs e)

{

GridEditableItem editedItem = e.Item as GridEditableItem;

UserControl userControl = (UserControl)e.Item.FindControl(GridEditFormItem.EditFormUserControlID);

string strUserID = editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["UserID"].ToString();

int intUserId = Convert.ToUInt16(strUserID);

using (ExpungeEntities db = new ExpungeEntities())

{

var Results = db.USERS_T_DATA.SingleOrDefault(i => i.UserID == intUserId);

if (Results == null)

{

RadGrid1.Controls.Add(new LiteralControl("Unable to locate that user for updating"));

e.Canceled = true;

return;

}

Results.FirstName = (userControl.FindControl("FirstName") as TextBox).Text;

}

}

Can you please tell me what the problem is?

Batch Edit - Keyboard Navigation with Arrow Keys

I'm now being told by my users that it's imperative to be able to navigate the batch edit using the up and down arrows. Essentially they are looking for the functionality of Excel in a webpage. Up and Down should go to the next or previous row, and left and right should be the same as tab / shift + tab.

Does this functionality exist? And if so how would I activate it?

Thank you.

radorgchart does not fully render until second execution

I have a page on which a user enters a few search criteria via drop down lists, and then searches for org chart results based on those criteria. I am having a strange issue in which the first time the search button is clicked, the org chart is displayed, but the formatting is wrong, and it's flowing off the screen.

See included screen shots of the first time the search button is clicked, and the second time. Second (and subsequent) search executions all render correctly.

<telerik:RadOrgChart RenderMode="Lightweight" runat="server" ID="RadOrgChart1" OnDataBound="radOrgChartDataBound" Orientation="Vertical" EnableCollapsing="true" EnableDrillDown="false" EnableDragAndDrop="false" EnableGroupCollapsing="true">

I'm new to the radorgchart function and using telerik tools in general, so any advice on where I should be looking for the source of this issue is greatly appriciated.
