Does anyone have an example of how to bind a TreeView to a BindingList or preferably if possible to a BindingSource? I have tried both, and just cannot seem to get it to work right. Thanks in advanced!!!

Strange layout issue after upgrade

All,

after upgrading to the latest control versions of Telerik all of my comboboxes in the ribbonbar got ugly somehow.

Please see the screenshot attached for reference.

I didn't touch anything and even if I create a new dropdown in the ribbon it looks the same way

here is the Designer code for this particular control. Please note that I am using the Office2010 theme.

Me.cmbReferenceWeek.ArrowButtonMinWidth = 16

Me.cmbReferenceWeek.AutoCompleteMode = System.Windows.Forms.AutoCompleteMode.SuggestAppend

Me.cmbReferenceWeek.AutoSize = False

Me.cmbReferenceWeek.Bounds = New System.Drawing.Rectangle(0, 0, 100, 22)

Me.cmbReferenceWeek.DefaultValue = Nothing

Me.cmbReferenceWeek.EditorElement = Me.cmbReferenceWeek

Me.cmbReferenceWeek.EditorManager = Nothing

Me.cmbReferenceWeek.Focusable = True

Me.cmbReferenceWeek.FormattingEnabled = True

Me.cmbReferenceWeek.MaxValue = Nothing

Me.cmbReferenceWeek.MinSize = New System.Drawing.Size(140, 0)

Me.cmbReferenceWeek.MinValue = Nothing

Me.cmbReferenceWeek.Name = "cmbReferenceWeek"

Me.cmbReferenceWeek.NullTextColor = System.Drawing.SystemColors.GrayText

Me.cmbReferenceWeek.NullValue = Nothing

Me.cmbReferenceWeek.OwnerOffset = 0

Me.cmbReferenceWeek.StretchVertically = False

Me.cmbReferenceWeek.Text = ""

Me.cmbReferenceWeek.Value = Nothing

How to select a textbox inside a page?

Hello!

If I create a simple RadForm with a single RadTextBox, this text box is selected (gets input focus and shows cursor) automatically when the form is shown. If I create a simple RadForm with a RadPageView and place the RadTextBox into the page, it is not selected automatically when the form is shown.

Even the following code does not select the text box:

protected override void OnLoad(EventArgs e)

{

base.OnLoad(e);

radTextBox1.Focus();

radTextBox1.Select(0, 0);

}

The following workaround does work, but I do not think this is a way I should go:

protected override void OnLoad(EventArgs e)

{

base.OnLoad(e);

Application.Idle += Application_Idle;

}

void Application_Idle(object sender, EventArgs e)

{

Application.Idle -= Application_Idle;

radTextBox1.Focus();

radTextBox1.Select(0, 0);

}

So, how should I correctly select the text box in the PageView page when the form is shown?

Thank you.

SelectedValue and SelectedItem

Hello.

I have a following problem with the combobox:
First I initialize my combobbox: Value column is a numeric field (Int64) , Display column is a Text field:

ddb_Broker.ValueMember = dtBrokerList.Columns[0].ColumnName;

ddb_Broker.DisplayMember = dtBrokerList.Columns[1].ColumnName;

ddb_Broker.DataSource = dtBrokerList.DefaultView;

ddb_Broker.SelectedItem = null;

When I retrieve data I need to populate the Broker:

ddb_Broker.SelectedValue = Convert.ToInt64(gl_dtProgram.Rows[0]["in_broker"]);

after this line in debugger ddb_Broker.SelectedValue = null ..... ? WHY ?

Please, help me to set this value. The same story happened with other fields ..

Thank you ,
Victoria.

Title bar not displaying

I just started my first WinForms app using Telerik controls today, so maybe I'm overlooking something, but my RadForm's title bar will not display. Here's what happens:

I compile and run my app (just one form).
It looks fine, but then I click on another app that brings it in front of mine.
Then I click my app's taskbar button to bring it back... no title bar.

Actually, the title bar is there as in it accepts mouse clicks and I can drag the window, but it doesn't draw itself or the controls on it. It essentially takes a screen shot of what's behind it, then THAT becomes the image of the title bar. That might be some partial text of a web page that was behind it.

This happens w/ VS2K8 on Windows Vista Ultimate x64 and Windows XP Pro x64. The latest service packs for everything is installed and I downloaded and installed Telerik Q1 2009 today.

Adding a new RadGridView

I'm having problems when I try to create a new RadGridView. From the toolbox, I select RadGridView and then draw a box on the form. When I do this it adds a reference to the control at the buttom, however it's not actually putting the control on the screen. I checked to make sure that it was visible and the back color was different. This problem has only started happening to me today, before today I could successfully add a RadGridView to my forms.
