Custom Grouping in PropertyGrid

[Holger Boskugel]

Hello,

is there a way to group properties (from a PropertyStore) in a custom defined order? How to do this?

Sample data:

Property 1: Name = Category; Category = System
Property 2: Name = Property1; Category = Properties
Property 3: Name = Property2; Category = Properties

The question is how to order the groups to System, Properties and properties in group alphabetical or by own order? Actually the PropertyGrid supports alphabetical group and property sorting, so the group order is Properties, System.

Regards from Leipzig

If I understand the original description. We want to change the order of the Categories (or Groups)? Ditto: is there any solution to this? Edit: and not just alphabetically; I'd like to customize this if possible. Thank you...

Hello Michael,

Thank you for writing.

Before getting to your question, we would like to check something related to your license. Your account shows no purchases and it seems that you have not downloaded the WinForms suite from our site. Since it is our policy to support users in good account standing, I will ask you to give us more details on the license you are using:
- In case you have downloaded it from another site/account, please let us know so that we can update your account and provide you with proper support services; 
- In case you have obtained a copy of our controls through the company you work for, please ask the purchase holder to add you as a License Developer to the purchase. This will give you full access to the products your company has purchased, to our downloads section, and to our support ticketing system. Additionally, all your questions will be reviewed according to the license you have. More information on License Developers you can find here: www.telerik.com/faq. 

If you have any difficulties or questions regarding this matter, please contact [e-mail] for further assistance.

As to the question at hand, you can achieve this by setting the category names of the properties with a prefix which would determine the sort order. Then you can handle the GroupDescriptors' CollectionChnaged event and set the group Label property to the text you want to be displayed for it. Here is an example:

RadPropertyStore store = new RadPropertyStore();

PropertyStoreItem item1 = new PropertyStoreItem(typeof(int), "Property 1", 0, "desc", "BProperties");
PropertyStoreItem item2 = new PropertyStoreItem(typeof(int), "Property 2", 1, "desc", "ASystem");
store.Add(item1);
store.Add(item2);

this.radPropertyGrid1.SelectedObject = store;

this.radPropertyGrid1.GroupDescriptors.CollectionChanged += new NotifyCollectionChangedEventHandler(GroupDescriptors_CollectionChanged);


private void GroupDescriptors_CollectionChanged(object sender, NotifyCollectionChangedEventArgs e)
{
  for (int i = 0; i < this.radPropertyGrid1.Groups.Count; i++)
  {
    this.radPropertyGrid1.Groups[i].Label = this.radPropertyGrid1.Groups[i].Name.Substring(1);
  }
}

I hope this will be useful. Should you have further questions, I would be glad to help.

Will get back to you on that matter. Thank you...

Hello Ivan,

thanks for your reply. Is there also a "solution" for sorting the properties in group by an own sort order (see example below)?

Order actually :

Group "xyz (Adresse)"
PropertyName "City"
PropertyName "Country"
PropertyName "Street"
PropertyName "Zip"

Required order:

Group "xyz (Adresse)"
PropertyName "Street"
PropertyName "Zip"
PropertyName "City"
PropertyName "Country"

or

Group "xyz (Adresse)"
PropertyName "Street"
PropertyName "City"
PropertyName "Zip"
PropertyName "Country"
