Two questions : DetailsPresenter rows empty and drag & drop doesnt work

[fred]

Hi,

Using the Datagridview to collect datas, I try to create a second gridview filled with the details (the main datagridview contains 6 columns and I want to sum it up to a 2 columns details gridview, with each row on column 1 containing the header of each of the main datagridview, and each row on column 2 containing the datas).

I thought the DetailsPresenter could help me doing that. Am I wrong ?
And By the way, I can display the so called Details Presenter but the drag & drop function doesn't even work. Why ?

Here is my code :

Thanks in advance

<Grid x:Name="LayoutRoot" Theme:StyleManager.Style="Grid_Background_Style">

Hi fred,

It seems that you have not linked the external details presenter. Please, take a look at this help topic and this online example?

Anyway, what is this drag-and-drop function that does not even work. What are you refferring to?

Sincerely yours,

Thank you, it will fit perfectly.

Just one more question, about the example.
I see a special reference in the assemblies.

 xmlns:local="clr-namespace:Telerik.Windows.Examples.GridView.RowDetails"

It seems it won't work without it; and I can't include this special assembly in my code, it would not be "clean".

Tia and Regards

Hello fred,

"Telerik.Windows.Examples.GridView.RowDetails" is the namespace of the concrete example. This is not an assembly. You do not need to include the examples assembly in your project. It is just an example.
