No option to print PDF to scale? PDF is shrunk when printed.

It is VERY important to us that PDF documents print to scale.I have read through the posts here and am still having the problem.

I am printing to a printer that has 0.16 in margins all around. The page size is 8.5 x 11. The drawing border is 8 x 10.5 (which would allow margins up to 0.25")

There are 2 images attached. Each shows an architect scale against the print out. One for Adobe, one for RadPrintDocument.
The Adobe prints to scale (the 120" wall at 1/2" scale shows 10 (10 feet). The RadPrintDocument is short as it is automatically scaling the PDF file down.
Also attached is the PDF file I am using for this example. Correction: PDF not attached as not allowed to attach to forum posts.

How can I stop that scaling please and always print to 100% scale please?

The code we are using:

RadPdfViewer rViewer = new RadPdfViewer();
rViewer.DocumentLoaded += RViewer_DocumentLoaded;
rViewer.LoadDocument(@fileLocation + fileName);
rViewer.LoadElementTree();
Application.DoEvents();

private static void RViewer_DocumentLoaded(object sender, EventArgs e)
{
RadPrintDocument document = new RadPrintDocument();

document.Landscape = true;
document.DefaultPageSettings.PrinterSettings.Copies = 1;
document.DefaultPageSettings.Margins = new System.Drawing.Printing.Margins(0, 0, 0, 0);
document.AssociatedObject = (sender as RadPdfViewerElement);

document.Margins = new System.Drawing.Printing.Margins(0, 0, 0, 0);
document.DefaultPageSettings.Margins = new System.Drawing.Printing.Margins(0, 0, 0, 0);
document.OriginAtMargins = true;
document.HeaderHeight = 0;
document.FooterHeight = 0;
document.Print();
}

Thank you!!!

Incorrect Behavior of some elements when DPI Scale is not 1

OS: Windows 7

Scale Settings: 135% (1.35 in DPI Scale)

Spotted problems:

1) radSplitContainer, collapsible - when collapse/restore first panel it restores 1.35 larger than it was.

2) CommandBarElement.SaveLayout/RestoreLayout - restores elements in a wrong position. Elements that aren't aligned with left or top border will be moved right and bottom correspondingly. I guess it saves position adjusted to DPI Scale, but restores as not adjusted

Both can be easily reproduced with QuickStart example (e.g. split container). Repeats on the current prod version and on the current xxx.308 beta.

[Solved] Remove Duplicate Child Nodes in RadTreeView?

Hello!

I have the following RadTreeView and I would like to know if it's possible to remove duplicate sub-nodes. Here is how my tree looks like.

[MAIN NODE 1] | (text = Main Node 1) | Name = Node1

[SubNode1]

[SubNode2]

[MAIN NODE 2] | (text = Main Node 2) | Name = Node2
[SubNode1]
[SubNode1]
[SubNode2]

How would I loop through all the main nodes and remove all the duplicate child nodes?

I created my main node dynamically through code and do not store their .Name property so I cannot just use RadTreeView.Nodes(MainNode)

Is there something like..

For Each MainNode In RadTreeView1.MainNodes

Loop through and delete child nodes if there is a duplicate

After binding the data, what do I do when I automatically empty the text in the raddropdownlist control as soon as I type the wrong option?

I used the following code to customize the raddropdownlist control, but it didn't work

Public Class clsHYCombo

If RestrictContentToListItems AndAlso Me.Items.Count > 0 Then
Dim index As Integer = Me.FindString(Me.Text)
If index > -1 Then
Me.SelectedIndex = index
Else
e.Cancel = True
Me.Text = ""
'Beep()
End If
End If
MyBase.OnValidating(e)
End Sub

'Protected Overrides Sub OnKeyPress(ByVal e As KeyPressEventArgs)
' MyBase.OnKeyPress(e)

Restore selected/expanded row under column grouping

Hello,

I've posted a thread about save/restore row 2 months ago. It worked great until I grouped a column.

When a column is grouping, the row index that I save/restore is the index in the grouping zone where the row located. When I load this row index to the gridview, every grouping zone will take over this row index. For example if I save a selected row, when I reload its index, all rows which has this index in every grouping zone will be selected.

If you would like to test, check out the demo in my old post (Hristo's answer):

https://www.telerik.com/forums/restore-selected-tab-in-hierarchy-child-page-view-after-data-refresh

Thank you by advance for your help.

Regards,

GridView
