Update generic list

Update-List allows you to use the Add and Remove parameters in a single command. Specifies the property values to be added to the collection.

Enter the values in the order that they should appear in the collection. Specifies the objects to be updated. You can also pipe the object to be updated to Update-List. Specifies the property that contains the collection that is being updated. If you omit this parameter, Update-List returns an object that represents the change instead of changing the object. Specifies a new collection. This parameter replaces all items in the original collection with the items specified by this parameter.

Objects or System. Update-List returns the updated object, or it returns an object that represents the update action. Skip to main content. This browser is no longer supported.

Taking the code as is I still get the error cssClass can't be assigned to as it is read only. Any more ideas? Code is great - thank you! Cheers John. Thursday, July 1, AM. User posted Hi Santhosh, I was also looking for the solution you proposed, but what if i also want to update the name Wednesday, October 13, AM.

User posted You can create a function to update both name and css class. User posted I get erros when I try to follow your advice, but maybe I'm doing something wrong in my code. See below my code and the erros. So I need to get those 4 counter fields from selectedItems and update the availableitems list.

Both list "availableitems" and "selecteditems" have the same structure. So I loop over the selected items and try to get the 4 counter values from this list and tr. Error 95 The best overloaded method match for 'System.
