[Solved] ScrollablePanel: Scroll in designer?

Hi Team!

could you please help me with a short question: How can I scroll within the scrollablepanel when I'm at design time? I have to design a large form with scrolling. But I can't do this, because I'm not able to scroll down the scrollablepanel at design time?

Thanks in advance,

Markus

Avoid throwing exceptions when deserializing

In our organization, we break when exceptions are thrown. This allows us to improve our code by eliminating exception-throwing as much as possible. Not a problem for our customers, but we don't want to turn this off for our developers, who use it to find problems in the code.

Because of this, we discovered that the Dock code always throws an exception when deserializing the layout because it's trying to create an Image type. Image is abstract, so it throws an exception, catches it, and continues on its way. The code below (from ComponnentXmlSerializer.cs) could be improved by first checking if the type has a paramterless constructor, and then not catching the MissingMethodException. This would speed up deserialization and let us keep "break on exceptions" turned on.

try

{

newInstance = this.InstanceFactory.CreateInstance(type);

}

catch (TargetInvocationException)

{

return;

}

catch (MissingMethodException)

{

return;

}

XmlSerializers.dll

In our product, we have used sgen to create .xmlserializers.dll's for all of the classes we serialize/deserialize for three reasons.

First, because we've run into cases where customers had .NET installs that actually failed to dynamically generate the xml serializer classes on the fly.
Second, it improves performance.
Third, we break when exceptions are thrown. This allows us to improve our code by eliminating exception-throwing as much as possible. When there is not a prebuilt xmlserializer dll, the framework throws an exception, which breaks into the debugger. Not a problem for our customers, but we don't want to turn this off for our developers, who use it to find problems in the code.

We cannot generate xml serializer dlls for the Telerik stuff, because they need to be signed using the same key used for the assembly the types come from. Could you guys provide these dlls for your releases?

[experience sharing] focus theft

When clicking on the application menu, in the quick access toolbar or on a ribbon tab, the ribbon bar control steals the focus from whatever control was focused.

I found the following solutions:
- quickaccesstoolbar: ribbon.QuickAccessToolBar.InnerItem.Children[2].CanFocus = false;
- application menu:
ribbon.RibbonBarElement.ApplicationButtonElement.CanFocus = false;
ribbon.RibbonBarElement.ApplicationButtonElement.ActionButton.CanFocus = false;
- tabs: tab.CanFocus = false;

RadTextBox/RadDropDownList and the Context Menu

I have a RadTextBox and RadDropDownList (DropDown style) on a winform and when I right click at runtime the context menu that pops up contains the usual cut/copy/paste items but it also has "Right to left Reading order", "Show Unicode control characters", "Insert Unicode control character", "Open IME" and "Reconversion" items. How can I disable/hide these unwanted context menu items?

Thanks!

ScreenTip Delay

I am using the ScreenTip feature to show some extra info in my RadGridView row when mousing over. That is working great but the delay is a bit much before it pops up when you mouse over it. I noticed here that the regular ToolTip has lots of properties that can be set to adjust this:
http://www.telerik.com/community/forums/winforms/gridview/tooltip-visible-time.aspx

I am wondering if you can include some code with samples here on how to do the same thing with the ScreenTip. Changing the code from that sample around didn't seem to work.

Thanks in advance!

Sorting Grouped GridViewComboBoxColumn

I have combobox column that is populated with id's and set up to show the given name as a display member. I also set DisplayMemberSort to true.

' create location combo box column

col = grdPurchases.Columns("location_id")

col.DataSource = locations ' DataGrid with "id" and "name" columns

col.DisplayMember = "name"

col.ValueMember = "id"

col.DisplayMemberSort = True

This works great and sorting the column sorts by display member and not value member like it should. But when I group by this column it seems to revert back to sorting by value member when sorting the groups.

' create default groupings

Dim locationDescriptor As New GroupDescriptor()

locationDescriptor.GroupNames.Add("location_id", System.ComponentModel.ListSortDirection.Ascending)

grdPurchases.GroupDescriptors.Add(locationDescriptor)

Is this supposed to happen? Is there a different way to keep sorting by display member?

AutoCompleteBox: Cancel creation of new tag

Telerik,

If my program detects that new tag has been created, then I would like to have a message box prompting the user if they want to create the new tag. If they choose 'No' then the tag will not be created.

How would I cancel the creation of a new tag?

Thanks
