Accessing Fields within a Collection from UIModel

Ernest Noa

Is it possible to programmatically access fields within a collection from UIModel.


In this case, I have a list of members in a collection. This collection includes a Is Primary Member field. I'd like to treat this like a radio button, where only one row may be set to true at any given time. I thought about handling this in TSQL, but if someone has clicked three or four people as the primary member, it's a bit of a mess. It would be better to handle this in VB or C# as the value is set on one row, to unset it for all others.


I figured accessing a field within a collection would be the logical place to start, but I can not seem to get any traction on this.


Any suggestions?


Thanks in advance.

The best way I found is to use foreach loops. You can loop through the collection fields value property that contains objects representing the rows in the collection. For example, you could try something like below to access them. You can also tie into the on-changed event handler for the collection field and access the field the same way to handle the logic. Hope this helps some.


foreach (var m in MEMBERS.Value)

{

m.ISPRIMARY.Value =

}
