Application freezes when coming out of screensaver mode

The application I am developing largely relies on Telerik components from the following namespaces (referenced DLLs): WinControls, Docking, GridView, RadDock, Themes, UI and UI.Design. I am using Telerik RadControls for WinForms Q2 2009 SP1 (2009.2.9.729). The three people who are testing the application before it moves to production are all experiencing the same problem.

THE PROBLEM: The application works fine and has no issues with unresponsiveness or freezing UNTIL they will allow the application to run and let their screensaver come up while they do paperwork and then when they unlock their PC the app is frozen, most of the time it is just a white box where the app was. This used to be an issue for me but since I have upgraded to Windows 7 I haven't had a problem with it. The beta testers are all using Windows XP SP2, which is what I was using when I had a problem except i was on SP3. Their machines are more than adequate to handle the program as it is a simple data entry program as was mine.
I suspect either the docking or theming element in telerik is causing an issue but I haven't been able to trace it down.

Is this a known issue with a fix?
Is anyone else having this issue?

Cannot add columns to grid

Using 2011 Q1 Release. I added a new grid to a VB.Net form. I opened the property builder and added a column. When I clicked OK, the column was not on the grid. When I reopened the property builder, the column I added was not there. See attachments.

RadContextMenu with RadTextBox

Ok, I've read about how the RadTextBox is the MS Hosted, but I'm not 100% what it all means.

Basically. I want to stop the default context menu from popping up, and add my RadContextMenu instead.

I have the RadcontectmenuManager added to the form, and the RadContextMenu property set in the radtextbox properties, but the default menu still appears,

Can this be done?

Thanks!

Master-Detail contains no detail data

Hello,

I'm evaluating the GridView component. In any case there will be no detail data bound to the grid.
Only if I'm using AutoGenerateHierarchy = true the detail will appear.

Previous steps in the designer:
- Defined two columns for master template (Vorname, Nachname) -> FieldName and HeaderText
- Created a new template called 'childTemplate' and add two columns (Firma, Ort) -> FieldName and HeaderText

As follow the code behind:

using System;

using System.Collections.Generic;

using System.Windows.Forms;

using Telerik.WinControls.UI;

namespace TestForm

{

public partial class Form1 : Form

{

private readonly List<Person> _personen = new List<Person>();

public Form1()

{

InitializeComponent();

_personen.AddRange(new[]

{

new Person {Vorname = "Danny", Nachname = "Meier", Jobs = new List<Job>

{

new Job {Firma = "Heiniger & Partner AG", Ort = "Wetzikon"},

new Job {Firma = "Scor AG", Ort = "Zürich"},

new Job {Firma = "ERNI Consulting AG", Ort = "Zürich"}

}},

new Person {Vorname = "Michael", Nachname = "Bolliger", Jobs = new List<Job>()},

new Person {Vorname = "Daniel", Nachname = "Kuster", Jobs = new List<Job>

{

new Job {Firma = "Heiniger & Partner AG", Ort = "Wetzikon"}

}}

});

}

private void Form1Load(object sender, EventArgs e)

{

radGridView1.AutoGenerateHierarchy = false;

var relation = new GridViewRelation(radGridView1.MasterTemplate, childTemplate);

relation.ChildColumnNames.Add("Job");

radGridView1.Relations.Add(relation);

radGridView1.DataSource = _personen;

}

public class Person

{

public string Vorname { get; set; }

public string Nachname { get; set; }

public List<Job> Jobs { get; set; }

}

public class Job

{

public string Firma { get; set; }

public string Ort { get; set; }

}

Thank you for any assistance.

Kind regards,
Danny

[Solved] Expanding and collapsing databound tree nodes by condition at startup

Hello,

in our scenario we have a treeview bound with self referencing items.
The goal is to serialize the expansion node states when leaving the application and restoring them on resumption.
While the serialization works just fine we have run into an issue trying to expand and/or collapse nodes when they get created.
On first glance the NodeFormatting event seemed promising since it gets fired at the right time.
Unfortunately any manipulation inside its handler, no matter how small, causes the node not to be shown in the tree, thus leaving our tree empty, since all nodes get formatted this way. We currently set this issue aside, but need to implement it at some point in the future.
Any help is greatly appreciated.

Rotate a vertical column header by 108 degrees

Is there a way to rotate the text of the column header by 180 degrees when it is set to vertical?

What I mean by this is that I have my column headers set to vertical, but the text is written from top down, and I would like it to be written from the bottom up.

Thanks.

EDIT: The title should read 180 degrees
