RadForm Normalize Icon Incorrect

Environment:

* WinForms 2009 Q1 SP1 (2009.1 414)

* VS 2008 SP1

* Windows XP Pro SP3

When a WinForm is normalized, the middle icon in the control box (right side of title bar) is a single box with a thicker top. Clicking this button to maximize the form, the middle icon changes to two overlapping boxes, singifying that you can normalize the form by clicking this button.

Just by changing the WinForm to a RadForm and doing nothing else, you lose the overlapping box icon when the RadForm is maximized. I.E., the RadForm always displays the single box with a thicker top, whether currently normalized or maximized.

To reproduce:

* Start a vanilla VB Winforms project

* Drag a RadButton onto the form, then delete the button (this auto sets refs to Telerik assemblies)

* In Form1.Designer.vb, make the form inherit from Telerik.WinControls.RadForm

* Run the project. The form is normalized and displays the correct middle icon in the control box.

* Maximize the form. The form is maximized and still displays the "maximize" icon, instead of displaying the overlapping boxes.

A pair of bitmaps illustrating the issue (one WinForm, one w/RadForm) is one folder down in the zip file, which also contains a sample VS2008 project:

Sample Project and Bitmap of Issue

If you don't fix this (and the other issue I just posted in this area), I'll have to redo my form as a vanilla WinForm. When shall I expect a fix for this?

First steps with the new Docking Framework

Hi,

I managed to port parts of my app to the new docking framework, was relatively painless once I found out how to convert UserDockForms.
A lot of things are more logical than before, performance not bad apart from a few redrawing glitches.

- Too bad that the DockWindow Image is still not shown in the drop down menu of the docking tab strip
- Maximizing the app with a couple of docked documents leads to excessive redraw and takes much longer than with the old framework
(DockManager on a simple Windows Form with RadMenu and RadTabStrip)
- This depends on the machine, on my Dell XPS quad core with 4Gig and nice graphics performance is acceptable, still some noticeable flickering though

Erwin

Error in Column

Hi..
I'm using ADO Entity Framework and displaying information in a GridView...
But I have a problem...
This is the code I use to obtain information:

radGridView1.DataSource = context.CF_Actividad.Select(

"it.ACT_Clave as [clave.clave], it.ACT_Descripcion").Execute(System.Data.Objects.MergeOption.OverwriteChanges);

note: CF_Actividad is my table.

well, ACT_Clave column has an alias, when this alias contains a dot(.), the information in this column is not displayed..
However, the information in the column description, if displayed.
The problem is when has a dot in the alias..
Thanks!!

radtextbox cursor

I have a radtextbox where I have the font set to blue, cursor to hand, and underlined...our users want it to behave like a hyperlink. When I hover over the textbox, the HAND cursor only appears when I'm near the border of the control. When I'm over the actual text, it turns to IBeam...and the Click event isn't fired. What's the trick.

Setting Initial Tool Window Size

How can I set the initial Tool Window Size when I add a Tool Window to the Manager?
I add first the Tools, then the Documents. The Tools should have a given Minimum Size if possible, the Documents then can adjust.

In the old Docking System I had to use a workaround to set the Size, is that still required?

RadMenuComboItem Events

Good day!

I've got two inter-related combos in the ribbonbar quick access menu, which will change the entity I'm looking at in my application, and I'd like the user to be able to select values in the following way:-

a) By typing in the field, pressing enter

b) By selecting an entry from the dropdown

c) By using the arrow keys

The problem I'm having is that I don't want to change the entity being looked at until either the user as pressed enter, or clicked on a specific item.

I've met the first requirement by handling KeyPressed and looking for '\r', which works fine. I can't find an appropriate item level handler. SelectedIndexChanged et al fire every time the user hits an arrow so that's no good.

I see you can manually assign a Click handler to each item in the radcombobox except that these two combos are databound, and have several hundred entries in each.

Because they're in the quick access menu, I can't think of any useful alternative options (e.g. having a "launch" button next to the combo for example, because when you select the item in the combobox, the menu disappears before you get a chance to click on anything else in the menu)

Any thoughts would be appreciated, and I'm more than willing to consider different options here.
