CollectionElements of a Collection of Collections as ItemSource

[Patrick]

Hi together,

iam the new one here :D

I have a "small" Problem, iam trying to bind a collection of elements to a datagrid and trying to access the elements of the nested collection to the datagrid. Is that possible?

Maybe a mini example

public class Example1CollectionElement
    {
        public int Example1ID{ get; set; }
        public Example2Collection Examples2 { get; set; }

}

Example1Collection test = GetAllExamples1();

DataGrid.ItemSource = test

How to show for each Example1CollectionElements all Example2CollectionsElements in the Grid without using a List or a SubGrid?

I hope my question is understandable :D

Hi Patrick, 

 

Thank you for using Syncfusion products. 

 

We are unclear of your requirement that to show the nested collections to load in the GridControl in flat grid (to show all the columns in main grid itself). Please share us some image representation of your exact requirement and confirm that whether you are using SfDataGrid for WPF or GridControl. So that, we could analyze further to provide you a better solution at the earliest.

Hi Arulpriya,

the requirment or the reason i want to build it this way, is the complexity of the collection it self. The collection looks like this

• person
• personProp1Collection
•      personProp1PropCollection
•           personProp1PropPropCollection
  
• personProp2Collection

It represents the hole Database and is generated on application start. So i hope to reduce the loading time during runtime. But to show or to edit some child,child,child Collections i need to show them in a SfDataGrid.

I tried it this way <syncfusion:GridTextColumn MappingName="PersonProp1.PersonProp1ID" HeaderText="PersonProp1ID"/>

But with that it only work if i use

Datagrid.ItemSource = person[index]

But i want to show

<syncfusion:GridTextColumn MappingName="PersonProp1.PersonProp1ID" HeaderText="PersonProp1ID"/>

that for all Persons without loading it in a list.

The reason behind that construct is the that i dont want to update the hole collection of collection during the runtime. Just safe it to the Database and working in the lokal storage.

I hope that explains it better, if not, maybe i need to search someone that can translate my problem xD
