Demo for muti-row client-side programmatic edit?

[John Hutchinson]

Hi guys, I've been pouring over the demos looking for a solution to a scenario i'm facing, and I'm starting to get a little bug-eyed so I thought I would throw it out there...

I have a radgrid with rows that contain a location, a quantity, and a dollar amount like this:

• location X, qty 1, amount $1
• location X, qty 2, amount $1.33
• location Y, qty 1, amount $1.01
• location Y, qty 2, amount $1.17
• etc

I have a radwindow pop-up that 'sits on top' of this radgrid (actually a separate aspx). The popup allows them to enter a value that will be used to adjust the amount for all rows matching a given quantity. So if I pick qty 1 and adjust by .1 (up), i want to programmatically and automatically update the data for the matching rows in the grid. regardless of the value of location. In this case the data would look like this after the update:

• location X, qty 1, amount $1.1 (updated +.1)
• location X, qty 2, amount $1.33
• location Y, qty 1, amount $1.11 (updated +.1)
• location Y, qty 2, amount $1.17

I have the radwindow passing back the necessary values and I'm trying to plug through the JavaScript necessary to programmatically  1) loop through and find the rows with the matching quantity (it's a key field), 2) edit them with a new amount, 3) post the update.Sort of an automatic batch update.

Is there a demo on this scenario out there? I'm sure I'm missing it.

Thanks!

location X, qty 1, amount $1

Hi John,

 You can check out the client-side API for the grid which contains many useful methods for iterating (get_dataItems()), editing ( editItem() ) and updating (udpateItem() ) items. Similar demos for batch update and window editing can be found here:
