Hello,

I have a pretty big GridView with about 13 columns. The current insert functionality is done through a popup window, I would like to change that to a modalpopup.
My issue is that my current insert popup is pretty complex with severals dropdownlist which generate postback when index is changed in order to re-populate the other dropdownlist. I also have a search function with a combo type ahead.

In term of performance, should I use a web-service for the modalpop to handle all of my insert functionality or should I just have all the code in the page that contains the modalpopup extender?

Thanks

Hey,

You could put a formview or detailsview in the modal popup and get that to work that way.  For drop down lists, check out the CascadingDropDownExtender, as that might help.  You could wrap this in an updatepanel too, to postback asynch, or if you like you could use web services, which requires more JavaScript coding effort.

Thanks for your suggestions, but in term of performance, should I use a webservice instead?
Thanks

From the performance perspective, yes probably it is.
