Hi,

We are using a RadDocument using the paged layout to show tabular content.
We create a table and inside each row we place some paragraphs. These paragraphs may have "SpaceAfter" property to zero, one or two lines.

One requisite of our application is to know how many rows are in each of the pages, so we can insert an extra row at the bottom of each page summarising the page rows and save it as a word document.

We were using the method "GetAssociatedLayoutBoxes" to get the layout box associated with each row and its heigth. However it seems that the size of the box is different than the actual size when exported to word using the DocxExporter.

It seems that the layout engine works different in RadRichTextBox than MS Word. For example, if I open the same document using word it appears that 12 rows are shown on the first page, but if I open the same document using RadRichTextEditor there will be 16 rows shown on the first page. The page margins are the same in both cases.

After deeply looking at the differences I would think that difference is due mainly to two things:
- The "SpaceAfter" property is rendered diffently by MS Word than the richtextbox
- The table borders take some space in MS Word and push the content down, but they do not behave in the same way on Radrichtexteditor. Even more, if I increase the table border width, the table seems to "grow" towards inside the cell instead of increasing the table height and width.

Is there any suggested workaround for this?
Will this be handled differently on Q3 2014 ?

Nodes order after Drag&Drop

Hi,

I have trouble with node dragging. It can be reproduced in your demo "Demo Application - Telerik UI for WinForms Q2 2014 SP1". Select "Tree View" -> "Drag & Drop". I am using left tree.
1. Click on the node "Drafts";
2. Press shift button and click on the "Outbox" node;
3. Release shift button;
4. Press left mouse button on the "Outbox" node and start dragging;
5. Drop selected nodes after node "Large Mail".

You can see that order of nodes was changed.
Before: "Drafts", "Inbox" and "Outbox"
After: "Outbox", "Drafts" and "Inbox"

How I can change this behavior?

Reflecting Custom Object Changes in RGV Hierarchy

Hi,

I am using the hierarchy feature of the data grid. My data consist of two custom objects one composed of the other.

class MyClassA : INotifyPropertyChanged

{

String Porperty1 {get; set;}

BindiingList<MyClassB> Items {get; set;}

//...

}

class MyClassB : INotifyPropertyChanged{

String Property1 {get; set;}

int Property2{ get; set;}

//...

}

(My actual classes invoke the PropertyChanged event. I did not show the full setters here for simplicity.)

I am setting a BindingList<MyClassA> as the data source for the grid view. I understand from this post here that you must handle the change event on the data grid when using the hierarchy view. I did this below:

private void dataGrid_CellValueChanged(object sender, GridViewCellEventArgs e)

{

//if the column is from the child view we must handle the change to the data model directly

if(e.Column.OwnerTemplate == gridViewTemplate1)

{

var b = e.Row.DataBoundItem as MyClassB;

var property = typeof(MyClassB).GetProperty(e.Column.FieldName);

property.SetValue(b, e.Value, null);

}

This works for updating the data model when changes are made to the UI. How do I see changes reflected in the UI when changes are made to the model?
