Hi Plamen i really do appreciate your help i need a a bit more help. In your solution i want to add 2 more coloums 1 checkbox and the other bound data coloimn named SETS values 2,4,1,
what needs to happen on the button click in the header is i want to work out for the items which have been checked is get the value from the header and divide by databound coloumn SETS but only divide if value is more than 1

so if i put 12 in the header and click on the button the items will be 6,3,1

Can this be done in javascript?

Thanks

Rishi

Hi RISHI,


You can use get_dataItems(). It is important, that this method will create all RadGrid client side items, which might lead to a performance penalty if RadGrid displays too many items in one page. Please find attached a sample web application that demonstrates the needed approach.

More about the client side API of the control you can learn from the Client-side API reference section in the grid documentation:

Hi Plamen , I noticed 1 thing it does not work in firefox any reason why?

Is there any way to capture if any item textboxes have remainder (not a whole number) give warning next to the item that we will round the value up for that item checked?

i will show a max of 25 items in the grid.

Thanks

Rish

Hi RISHI,

Up to the questions:

1) We have modified the sample application to incorporate the changes necessary for FF. Please review it and let us know how it goes.

2) The JavaScript Modulus Arithmetic operator returns the remainder left after division. Here is an example:

 
var a = 70 % 16; 
(a is now equal to 6, since the remainder left 
after dividing 70 by 16 is 6) 
var b = 64 % 8; 
(b equals 0)
