Dear Telerik,

I'm experiencing a small problem regarding the radgrid in combination with filtering, paging and using a custom aggregate function.

The scenario is as following:

We have a grid with 1 mastertableview. The columns are not auto generated, but are either bound or a template.
The grid supports filtering (both textbox and combobox filering in the column headers). Also paging is enabled.

In the grid we have 3 columns, named ColumnA, ColumnB, ColumnC.
ColumnC is the calculated result of ColumnA x ColumnB.
Below ColumnA and ColumnC we show 2 total footers. For this we used the aggregate function SUM. This works like a charm, and the totals are shown in the footer of the grid.This is the total of ALL items currently available in the grid. In other words, the total does both respect the filter and the paging. (say my datasource has 100 items, my filter reduces it to 70, and my page shows 50 items, the sum is calculated over 70 items, this is what we want).

In the footer of the ColumnB we want to show an average in the form of SUM(ColumnC) / SUM(ColumnA). For this we can't simply use the aggregate function AVG on ColumnB as it would give a different result than the one we need.

Whats the best approach to get the desired functionality?

I've tried to use the item databound event, but then it ignores the filter and i get to many items.
I've tried to use the custom aggregate function, but when i access the items from the masterviewtable, it only returns me the items of the current page i am in.

Atm i solved it in the pre render method. There i accesed the footer items for ColumnA and ColumnC, parsed the text properties back to values and calculated the result, and then set it to the footer of ColumnB.

But i am sure there must be some other approach.

Thanks in advance,

Ramon

Thank’s 

hi all,

well i have a question, i am using a telerik RadGrid to bind the data from the server end and i need the filter that data on the client end without hitting the server again i.e. without getting the data back from database.

i know it is possible with using columns and binding the data back with GridBoundColumn but my problem is that i am using ItemTemplate within which i am creating the table to make it look just like my client needs, so is it possible to filter the data in the ItemTemplate without columns(gridboundcolumns).

i hope i make sense out of it.

Thanks in advance, 

waiting for the possible solution asap.

Hello,

As I know it is not possible to upload the whole folder/directory using RadAsyncUpload control.
However, when I drag and drop folder, it is accepted, but upload fails of course.

Is there any way to cancel drop folder event?

I tried something like this:
And on server side
But then all uploaded files are lost, not just the problematic folder.

Alternately I when process uploaded files I can ignore those where the ContentLength is 0, but this also makes problems when user wants to upload empty file.

Thanks

I am using the RadTabastrip on demand load example. I have one RadDatePicker in the first usercontrol, which works fine. I want to have 2 raddatepickers in second usercontrol, but when second user control loads by clicking on the second tab, javascript needed to show the popup calender for those 2 raddatepickers does not load, so the raddatepickers don't work.
Can you please suggest how can I make that work?

Thanks.

Hi,

I am using RadScheduler with websevice (v.2012.1.411). I use args.get_schedulerInfo() to pass extra info to the webservice on event OnClientAppointmentsPopulating,  it is working well.

But when I try to use args.get_schedulerInfo() in event OnClientAppointmentWebServiceInserting, It pops up javascrip undefined error. I checked the online document http://www.telerik.com/help/aspnet-ajax/p_telerik_web_ui_radscheduler_onclientappointmentwebserviceinserting.html , This property should be supported in this event. here is the code,

Thanks in advance
