Single Control with DockStyle.Fill in ToolWindow or DocumentWindow Doesn't Resize

Hello,

I have built an application that uses the Winform version of both RadDock ToolWindows and RadDock DocumentWindows inside of a RadDock container.

Each of these RadDock DockWindows has a single textbox control or custom UserControl in it, with:

singleDockedControl.Dock = DockStyle.Fill;

The problem I am having is that when I expand/maximize the entire WinForm, the DocumentWindows and ToolWindows expand nicely, but the controls inside them look "cut off" on the righthand size... a textbox with a long line of text gets cut in half, and the last half of the line of text is not visible on the containing DockWindow, even though there is lots of empty white space on the righthand side of the containing DockWindow. It appears that the textbox grows correctly, due to its Dock = DockStyle.Fill, but the righthand side of the DockWindow doesn't get repainted to show it. This problem doesn't happen when a textbox or UserControl is placed directly on a test Winform that is expanded/maximized.

Does anybody know what I can do to fix this problem?

Thank you very much in advance for your help!

2011 Q2 Treeview - how assigning ImageKey on nodes?

Hi i fill the treeview via code and works well, but i need a way to asign a icon from a assigned imagelist on the nodes.
The Data assignemend is:

- ChildMember = id
- DisplayMember = Label
- ParentMember = pid
- Tag = ImageKey
- ValueMember = ImageKey

I have tested with the tag and the valuemember fields without success, the tag field is allways empty :(

I have tryed to assign the CollectionChanged event, ut it does not fire when the datasource is bound... !?

radTreeView1.Nodes.CollectionChanged += new Telerik.WinControls.Data.NotifyCollectionChangedEventHandler(Nodes_CollectionChanged);

List<TreeItem> items = new List<TreeItem>();

{

TreeItem t1 = new TreeItem();

t1.id = 1;

t1.Label = "Home";

t1.ImageKey = "airplane";

items.Add(t1);

}

{

TreeItem t1 = new TreeItem();

t1.id = 2;

t1.pid = 1;

t1.Label = "Level 2";

t1.ImageKey = "comments";

items.Add(t1);

}

radTreeView1.ValueMember = "id";

radTreeView1.ParentMember = "pid";

radTreeView1.DisplayMember = "Label";

radTreeView1.Tag = "ImageKey";

radTreeView1.DataSource = items;

void Nodes_CollectionChanged(object sender, Telerik.WinControls.Data.NotifyCollectionChangedEventArgs e)

{

RadTreeNode n = ((RadTreeNode)e.NewItems[0]);

((RadTreeNode)e.NewItems[0]).ImageKey = n.Tag.ToString();

}

public class TreeItem

{

public int id { get; set; }

public int pid { get; set; }

public string Label { get; set; }

public string ImageKey { get; set; }

}

Any help would be great
Thx

PageViewStripElement Bakcolor on unselected tab

I have an need to change the tabstrip backcolor to something other than the theme color when there is certain information in a tab. So far I have been able to use this:

Dim pageViewStripElement = TryCast(DirectCast((tcOrganization.ViewElement).ContentArea, Telerik.WinControls.UI.RadPageViewContentAreaElement).Owner, RadPageViewStripElement)
DirectCast(pageViewStripElement, Telerik.WinControls.UI.RadPageViewElement).Items(1).NumberOfColors = 1
DirectCast(pageViewStripElement, Telerik.WinControls.UI.RadPageViewElement).Items(1).BackColor = Drawing.Color.Yellow

That works fine if you mouse over the tab button but I want it to stay that color even in a state that is not moused over or selected. How can I accomplish this without out using the theme builder. I need to be able to have this happen for separate tabs on different forms so being able to accomplish this programatically is a must. Thanks for any help!

Translation only works partially with RadSchedulers

Dear Telerik Team,

I'm current using Q1 2011 SP with VS2008. When applying the example in the help file for the RadScheduler to translate the RadScheduler strings and in example:

RadSchedulerLocalizationProvider.CurrentProvider =

New CustomSchedulerLocalizationProvider

Everything appears translated in the local language except the days of the week in RadScheduler's header columns which are still in English:
Monday, Tuesday, Wednesday...
Is it possible to programmatically change the text of these header columns?

Best regards,
Alain

Default Backcolor for Button Fill Element

Hello,

I am using a lot of Rad buttons in my application. I change the back color of the buttons based on some conditions the following code:

.ButtonFillElement.BackColor = Color.LightGreen;
.ButtonFillElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid;
.ForeColor = Color.Black;

My questions is how do i set these properties back to the default ones within code. I want the buttons to get the default theme of the application when the condition turns false.

Thanks,
Pawan

RadComboBox does not show focus ques

I have several RadComboBoxes (Q2 2010). I have AllowShowFocusQues set to True, TabStop set to true & DropDownStyle set to DropDownList.

When I tab onto the field there is no change in the appearance of the combo box. I know I have focus because I can use the arrow keys to move through the list. I would have thought may do something like the DropDownList or button with a dotted box just inside the control's border.

The list does include a blank item that is shown initially. However even if I select a different item from the list, tab off and then back to the combo box there is no indication that the combo has focus.

Thanks!

You have introduced a new property called 'Visibility.' How do you change that value programmatically? I would like to change it: lets say from initially 'Hidden' to 'Visible' in code.
