If Convert.ToInt32(e.VisualItem.Tag) / 2 = 0 Then 'images

e.VisualItem.BackColor = Color.Azure

e.VisualItem.Size = New Size(950, 259)

Else 'descripcion of image

e.VisualItem.BackColor = Color.Black

e.VisualItem.Font = New Font("Consolas", 20, FontStyle.Bold)

e.VisualItem.Size = New Size(950, 50)

End If

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?

Grid is not saving layout when columns are grouped

We allow our users to reorder columns. Everything works when there is no grouping. I looked at xml layout and columns are saved in order they appear on screen.
But when we create groups programmaticaly the saved layout is always the same. Even if I reorder groups xml layout save doesn't change.
I tried to modify it by hand and reload and it worked. I moved columns of groups in and they appeared in modified order on screen.

One solution is to modify layout returned by grid to make it in line with order of groups on screen and then save it. But I don't like it.

I'm using Version=2012.1.321.20
