access Custom item to fill data CustomDetailListViewDataCellElement

[M]

Hi

 

I implemented  a (custom item - radListview) in a Listview using CustomDetailListViewDataCellElement

the view type of the parent ListView is Detailview and a data set is bounded to it

I want to fill the custom listview inside the parent listview with data

I can fill it with data at creation time

but after the cell has been created  , I can't

 

I don't know how to reach it

Hello M,

I am not sure what exactly you want to achieve. Could you please elaborate?

In general, when the control is bound it will reflect the changes automatically. When using custom items you need to use the Syncronize method to update the items. An example is available here: Custom items. 

I am looking forward to your reply.

Hi again

I wanted to set different items for each customDetailviewdatacell

which are RadListviewElemant s in my case .

However I maged to achive this by the following code in radListView1_CellCreating event :

var lv= e.CellElement.ChildrenHierarchy.FirstOrDefault(c => c.Name == "123");
if (lv is RadListViewElement)
{
((RadListViewElement)cb).Items.Add("item a");
}

 

Or by defining a public property in CustomDetailListViewDataCellElement and access it in Cell_Creating event

for ecample seting datasource of the child Listview

 

Now I'm facing another problem 

I don't know how to synchronize properties for a listview as a CustomDetailListViewDataCellElement  in Synchronize()

so as the result of that  when I scroll verticaly , my child listviews items change 

and I took care of IsCompatible for both custom cells and normal cells

 

Before scrolling :

1st row child listview items --> 1 , 2 , 3

2end row child listview items --> 7 , 8 , 9

and so on

 

After scrolling :

1st row child listview items --> 7 , 8 , 9
2end row child listview items --> 1 , 2 , 3
and so on

 

I will open a new thread for this problem

Hi M,

This is exactly why I have suggested the Synchronize method. The cell elements are reused and when this is done their content needs to be synchronized. 

We can continue to discuss this in the other thread that you have opened.
