ResourceView: restrict movement

Hi there,

when I allow a user in ResourceView to move items I want to be able to restrict movements either horizontally (only on timeline) or vertically (only to other resources). For vertical restriction I'm using the following code:

Code (C++)
Select All
private void onItemModifying(object sender, ItemModifyConfirmEventArgs args)
{
       //First of all we need to restrict movement to resources (i.e. in vertical direction only)
       args.NewStartTime = args.Item.StartTime;
       args.NewEndTime = args.Item.EndTime;
}


Unfortunately this won't work with resources because the Resource-property of ItemModifyConfirmEventArgs is read-only.

Any solutions on this?

Best regards
Achim

Hi,

You can prevent items from being moved to other resources by setting Calendar.ItemChangeResourceKey to any non-modifier key, for example Keys.NoName. This property however will only have effect at the start of the interaction. If you set it while the item is already being dragged, it will have no effect until a new item interaction has started.

Let me know if this helps.

Regards,
Meppy

Hi Meppy,

the point is: I want to prevent individual items from being moved to another resource. So I have a gantt chart with some items that can be freely moved, some only vertical, some only horizonally and some that are locked in place. It depends on their type and state.

Regards
Achim

Indeed this scenario is not currently possible. We will try to extend the control to enable it.

Hi, there,
I Purchased the product this morning, and I also need this functionality. As last entry in this thread is quite old, will you, please, advise whether the feature was implemented in the current version, or I will need a special fix. Thank you in advance!

Hi Nikola,

Back then we introduced a new property in the arguments passed to the ItemModifying event, which lets you choose whether an item can move to a different resource when dragged by the user. The property is called AllowChangeResource. Set it to false to prevent users from changing the resource of the modified item:

Code
Select All
calendar.ItemModifying += (s, e) =>
{
	if (e.Item.HeaderText.Contains("no"))
		e.AllowChangeResource = false;
};

Let me know if this helps.

Regards,
Meppy
