[Solved] Programmatically Created ToolStrip Renders Incorrectly

Hi,

I programmatically create interfaces rather than use VS.net Designer, and almost all Telerik Windows Forms controls work Ok with this, however I cannot get the toolstrip to render correctly using the default application theme. If I switch default application themes having created and loaded my new toolstrip it renders correctly but until I toggle the theme it looks poor.

I try to work around this by calling the following for each control I create at runtime;

private void applyThemeToGeneratedControl(Telerik.WinControls.RadControl control)

{

control.ThemeName = Telerik.WinControls.

ThemeResolutionService.ApplicationThemeName;

control.RootElement.ForceReApplyStyle();

control.RootElement.ForceApplyTheme();

}

which does work for the majority of controls, but not for toolstrip.

Any ideas what I'm doing wrong here ?

Thanks,
Phillip

Apply a custom theme to a DocumentTabStrip

Hello,

I am having trouble applying a theme to the DocumentTabStrip which is created when adding a Tabbed Document to a RadDock. I have the Visual Style Builder to create a style for a RadTabStrip which functions perfectly but cannot be applied to the DocumentTabStrip. I tried to create a style for the DocumentPresenterControl but when I load the default theme for it there are no states defined for the FillPrimitive for the DockableTab (even though the preview shows different states for Selected/MouseOver/etc.). I am able to get my RadTabStrip theme to show in the design view of VS2008 by loading documentTabStrip from assembly in Visual Style Builder and modifying a setting so that I can save it to my .xml file and apply my custom theme to documentTabStrip1 in my project, but when I run the program the theme returns to the default theme.

Where am I going wrong? I have been trying for quite some time to apply a custom theme to the DocumentTabStrip and am at a loss on what to try next. Also, when I did load the documentTabStrip into Visual Style Builder from the assembly, nothing appeared in either Design View/Preview but there were elements in the Control Structure.

Thanks!

[Solved] RadDock is not a ContainerControl

The Q2 2009 RadDock control does not SetStyle(ControlStyles.ContainerControl) and so is not seen in .net as a ContainerControl. This causes problems when calling Form.ValidateChildren or Control.Validate to force validation of controls held in a RadDock window.

My workaround is to explicitly handle the radDock_Validating event in my code like this;

private void radDock_Validating(object sender, CancelEventArgs e)
{
    if(! ((ContainerControl)this.radDock.ActiveWindow).Validate())
    {
        e.Cancel = true;
    }
}

The .net framework behaves oddly when cascading the Validate event through a control stack, and instead of simply iterating a controls .Controls collection, it explicitly checks to see if a the Control.GetStyle(ControlStyles.ContainerControl) is true before deciding to iteratve the .Controls collection. Because RadDock does not set this property it is in effect telling the .net Framework "I don't have any children, so don't bother looking any further". By manually cascading the Validating event as shown above, we jump this gap.

I don't know if this particular pattern is followed in any other cascading functionality in the .net framework.

[Solved] ToolTipText needed

Hello!
Look, I have a user control that works as a ToolBar that has some radbuttons on it. Those buttons are showing an image stored in the resources of the project, and I need to show a ToolTipText.

First I set the needed text through the properties window of each button (inside the RootElement property), and it didn't work.

Then I went to the designer.cs of the control and set manually the property (myButton.RootElement.ToolTipText = "some text"), and it didn't work.

Then, inside the designer.cs of the control I set manually the property in this way: ((Telerik.WinControls.UI.RadButtonElement)(MyButton.GetChildAt(0))).ToolTipText = "Open Model";. And guess what? ... It didn't work also!

Please help me, I don't know what else I can do.

Buttons, RadioButton, CheckBox, etc

Tab separator in WinForms?

It appears the WinForms radTabStrip does not support IsSeparator like the ASP.Net versions do. Is there any way to place 3 tabs left aligned and 2 tabs right aligned all on a single row?

Thanks!

Custom filtering

Hello,

Does the new release support the functionality of a custom filter row (I read in previous posts that you plan to do so)?

For example, my grid contains a column with enum values, I want to filter the rows in the grid by selecting one of the values from a drop down list.

Thanks

Cancelling the PanelBarGroup Expand/Collapse

It seems that in the 8.1.0.0 release, the PanelBarGroupExpanding and PanelBarGroupCollapsing "cancel" argument is not respected in the VS2005Toolbox GroupStyle. I haven't tried other styles because we like the look and feel of the VS2005Toolbox style.

When I set args.Cancel = true, the "Expanded" and "Collapsed" events are still fired and the +/- icon toggles, and the arg.Group's "Expanded" property is already changed at this point.

Is this something that is fixed with a newer release of the WinControls suite? Thanks!

RadPanelBar with "Protected" modifiers

Hello

I'm currently using RadPanelBar with a single panel group element in an inheritable form where I'm programming a set of common functions for all the forms that will inherit from it. I set the RadPanel modifiers property to "protected" so I can add new group elements in each inherited form for their particular functionality.

But when I am dessigning the inherited form, RadPanelBar properties appear as in read only mode, so I cannot add new panel groups, new controls in the panel group that already exists... etc.

Am I missing something? Is not possible use this control in the way I'm trying to?

Thank you in advance for your response.
