Hi i have a RadChildForm that is being used for an MDI interface. All instances of these child forms are being created at run time. I have given this child form several properties, however when i try to access these properties using this.MdiChildren.ElementAt(0) or just this.MdiChildren[0], i don't have access to any of the properties that I created. The only type of children it seems to get is just the plain system.windows.form, is there a way i could have access to Rad Child Form properties? Thanks in advance.

I'm having a theme issue regarding a rad scroll bar that is dynamically added to a custom component.

I have loaded the RadThemeManager and am able to check the count to see in fact that the RadThemeManager is loaded with our themes, everything looks to be loaded as expected.

I create the RadVScrollBar control and set correct the theme name.

However, when the page is loaded the scroll bar is still using the default theme.  Here are some code excerpts:

    public partial class ThumbViewer : RadPanel
    {
        public ThumbViewer()
        {
            InitializeComponent();

            // This will get all the themes loaded into a theme manager
            themeEngine = new APCM.App_Code.ThemeEngine();
            radThemeManager = themeEngine.GetControlThemes();
            MessageBox.Show(radThemeManager.LoadedThemes.Count.ToString());
            
            // Create and add the scrollbar
            scroll = new RadVScrollBar();
            scroll.ThemeName = "OurTheme";
            scroll.Dock = DockStyle.Right;
            scroll.ValueChanged += new EventHandler(scroll_ValueChanged);
            MessageBox.Show(scroll.ThemeName);
        }
    }

Like I said, the rad scroll bar is NOT loaded with the expected theme.

Thanks In Advance,
Josh

Hi,
I'm evaluating the RadControls for WinForms and see some effects I would call bugs...
But I'm not sure if this might not result from cruft on my machine (last re-install is sometime ago), so I'd just like to ask if someone can confirm my sightings:

- In the demos open RadDock/'Tabbed Document' or MDI, undock Log or Settings window and let it float somewhere, then grab it again and try to dock it back. If the transparent window you want to dock overlaps (even slightly) with the 'docking arrows' when they appear or disappear those arrows (after disappearing: at their new position) are filled grey and not filled with their blue bitmaps.

- in design mode, if I open the 'Property Builder' for the dropdown part of a RadMultiColumnComboBox and close it, I get a null-reference exception.

Both seem no 'showstoppers' but if I can find them after only short time of experimentation, it's not good for my confidence in these controls ;-)
So: are these reproducible by someone?

TIA, Juergen

Hi!

I am adding RadListBoxItem(s) to a RadListBox at runtime and I need to scroll to view the last one added. When I set the last one to SelectedItem the RadListBox scrolls to the selected item but only the upper half of the item, I "solved" it before by adding an empty item at the end, but now it is not possible and I need a "real" fix. ScrollControlIntoView can't be used since it takes a Control and the Items are RadItem(s). Any ideas?

Thanks,

I am using Visual Studio 2008 with VB, using the RadTabControl and RadMenu for my Wind Forms application.  I have, thus far, created a theme for each which have a consistent look. 

I would like to create a couple of additional themes and provide my users a choice of which themes to apply at run time, for example, with a checkbox in their user preferences form.  Each of my forms that has one or more tabs has a RadThemeManager which loads a single theme.
(FYI -- I have never been able to add more than one theme to a Rad Theme Manager without it automatically reverting to the default application theme that ships with your product.)

Can you provide me with a method and some code snippets fo make this possible? 

Thank you!
Meryl Smith

Hello,

I'm using a button to update a cell value that is in a radgrid. Some times all the cell values of a certain column.

I'm using the following code:

 

RGFiles.Rows(0).Cells(1).Value = RGProposals.CurrentRow.Cells(2).Value.ToString() & _

 

 

"_" & RGProposals.CurrentRow.Cells(3).Value.ToString() & _

 

 

"R" & RGProposals.CurrentRow.Cells(4).Value.ToString() & _

 

 

"_" & RGFiles.CurrentRow.Cells(2).Value

 

The code works fine (for one cell)  but if I'm updating a cell, i need to pass the mouse over the cell to update the value that is shown in that cell. If I'm updating all cells of a certain column, the cells show the new value but takes a lot of time to do that.

What is missing me? What do I need to do to resolve this problem.

Thank You.

Hi,
I am evaluating Winforms with VS2008 on XP.

I would like to create a menu strip with rad menu on top and a simple ribbon-style image below the menu. However, when I drag rad menu on top of an existing panel with an image, rad menu does not display the underlying panel image.  I have tried setting the rad menu property RadMenu BackColor to Transparent but the rad menu is still opaque and does not display the image.

I must be missing something as I am following the steps in your help documentation on radmenu.

Here are the steps:
1. Start new project with a form.
2. Drag windows panel control onto the form, assign an image to it.
3. Drag radMenu on top of win panel control, enter a menu text item.
4. Select radMenu item and from properties menu, select BackColor property item, then select 'transparent' from the web tab.

Thanks for letting me know wha tI am doing wrong.

Hi, I am evaluating Telerik WinForms - VS2008, XP and
Vista.

I have been testing out the RibbonBar control and have a problem loading the theme file as a project resource.   The Telerik theme works fine as a file when it is loaded from a directory on my local machine other than the project resources directory.

However, I  would like to keep the theme file in my project resources directory for project portability to be able to load it on other machines.  I am trying to create a project template from VS2008 which contains the theme file.  After I export my project as a project template the theme does not work (since it is trying to load from a directory on my machine) What is the trick to save the theme file as a resource? Thanks.

Other than this issue the evaluation has gone well and the controls look great.
