Check for zero quantity before closing page

Hi there, im sure theres a simple fix for this but ive been wrestling with code for too long now and im out of ideas :(

The screenshot attached shows how when the user arrives at that screen they choose a part listed by using a tickbox and then inputing the quantity required. At the moment its allowing a zero quantity to be ordered, and this causes an issue with the sql database.

I'm trying to find a way of checking before the user leaves the page (either by verification when they click the save button, or something else) to carry out a query on the tick boxes selected if the value is greater than zero. I dont want zero quantities to be allowed upon save

Ive tried following some of the example code listed on the Telerik demos, but cant find anything that verifies a line thats been selected by a tick box, and then checks that or other selected tick box lines for a zero quantity and erroring if so.

The page loads zeros as default when the page is 1st opened, which has partly caused my headache !

This is the aspx code:

Custom OnClientFileOpen for Image/Document Manager

I have implemented a custom FileBrowserContentProvider for image/document selection. I am currently using it with the RadFileExplorer and the RadEditor. Within the RadFileExplorer I handle the OnClientFileOpen event with some custom functionality. The issue is, I want to utilize that same custom functionality within the ImageManager and DocumentManager of the RadEdtior and I cannot find any reference to that event (OnClientFileOpen) within those dialogs.

Help?

Sorting/Filtering Not working with Hierarchy using NestedViewTemplate which loads data via ObjectDataSource

I have a grid with nested views via tempates. The tamplate retrieves data though an ObjectDataSource that gets it form a Webservice.
Now, when I expand any element in the hierarchy it works perfectly, however, if I try to sort or filter any column from the Mater Table, I get an exception:

Error: Sys.WebForms.PageRequestManagerServerErrorException: The DataSourceID of 'FormView' must be the ID of a control of type IDataSource. A control with ID 'ObjectDataSource' could not be found.

I have tried adding the same ObjectDataSource after the grid definition but it does work (not exception thrown) for sorting/filtering of the Master Table but if I try to expand any of the nested views, it simply does not show any data. However, if right before I try sorting/filtering the master table (right after I load the gid for the first time) I expand any of the nested views, they do get the data. It is only after I sort/filter that they don't.

The following is the code for the radGrid that I currently have, which is the one that forces the exception to be thrown:

<telerik:RadGrid ID="OrbitRadGrid" runat="server" AllowFilteringByColumn="True" AllowSorting="True" VirtualItemCount="50000"

So what can I do in order to have this work for both sorting/filtering as well as hierarchy expansion?

BTW, I do my own sorting/filtering as well as paging since I cannot load all the records from the database at once.

I am wondering if by intercepting an event and doing something I can stop the grid from trying to interact with the FormView in the NestedTemplateView at all since all I want is to sort the Master Table! .

Thanks.

Nested RadGrid updating all internal records

I have a grid which is populated from a webservice with the required data. I then have a nested template where I show, inside a FormView, further details for the partiular record I selected to expand. I created an object data source for this, which ultimately also talks to a web service to retreive the data.

It works fine for individual records retrieved one at a time, however, when I try to expand two records at the same time, both "views" are updated with the exact same information, instead of keeping the details for each record independently.

I think I know that this happens because it refreshes the datasource everytime I select a new record to expand. The problem is that I don't know how to tell the grid (and therefore the nested formview) not to refresh all open windows but only the one expanded.

Here is an excerpt from my code:

<telerik:RadGrid ID="OrbitRadGrid" runat="server" AllowFilteringByColumn="True" AllowSorting="True" VirtualItemCount="50000"

<asp:Parameter Name="itemName" Type="String" />

<asp:Parameter Name="itemSource" Type="String" />

</SelectParameters>

</asp:ObjectDataSource>

The OnNeedDataSource event is used for filtering of the Master table.

Is there anything I need to set in order to prevent the nested formviews to update with each request?

Thank you

HTTP Error 415 - WCF Load on Demand

Hi,
I have a RadTreeView in which I want to load the child nodes on demand (as it says in the Demo) using a WCF service I published to my Sharepoint Site.
The service works fine when I initialize the tree on runtime (I get the root's children when the page loads) however, when I open a node I get "The server method 'GetChildNodes' failed", using Fiddler I checked the source of the error and saw this:

"HTTP/1.1 415 Cannot process the message because the content type 'application/json; charset=utf-8' was not the expected type 'text/xml charset=utf-8'."

What am I doing wrong here?

Thanks!
