After a couple of hours of normal working, I started getting error messages about the old icons that were deleted. THe error message complain about missing these old icons. I closed the solution and reopened and surprise , all my buttons on ribbon bar dissapear, the only things remaining are ribbonbbarbuttongroup.

Error in Yearly Recurrence Pattern

Hey I just noticed that if you setup a Yearly Recurrence using the second option it doesn't work correctly.
It doesn't always reoccur yearly.

Example 1:
If I choose for the appointment to recur every first day of March with a end after count of 4, it reoccurs as a daily recurrence.

Bottom line: as far as I can see is if you have First selected in the first drop-down or anything other than a Weekday selected in the second opt. it screws things up.

Is there a fix for this?
Thanks!

WinForms RadTreeView "ShowLines" not working at run-time

I am using a Q3 2010 RadTreeView with "ShowLines" and "Show RootLines" set equal to "True" and LineStyle = "Solid". I have the Theme set to "Windows 7" which theme is also dropped on the parent Form.

I have only one root node added at design time. That nodes "lines' shows as configured in the Designer. But as soon as I run the program, the line disappears. When my code adds many other nested child nodes, no lines show for any of them either.

The .CHM file mentions only the "ShowLines" property without referring to any other required associated properties. Is there an associated property I need to set.to get the lines to show at run-time? Is there something about the Windows 7 theme that overrides my "ShowLines" setting? (I would expect explicit manual property settings to override any theme's defaults).

Thank you.
-Bob

Showing columns one under another in RadGridView

HI all,

Is it possible to arrange columns so that they will look like this:
----------------------------------------------------------------------------
                                       |   c o l u m n h e a d e r 2
                                               --------------------------------------
c o l u m n h e a d e r 1   |   c o l u m n h e a d e r 3
                                               --------------------------------------
                                       |   c o l u m n h e a d e r 4
----------------------------------------------------------------------------
                                       | column 2 data
                                               --------------------------------------
column 1 data    | column 3 data
                                               --------------------------------------
                                       | column 4 data
----------------------------------------------------------------------------

I've tried this with HTMLViewDefinition, but it doesn't help a lot. Using HTMLViewDefinition I faced issues with setting correct widths for the columns (every time it either auto fills if AutoSizeColumnsMode is set to 'Fill', or shrinks if it set to 'None').

Setting a view.RowTemplate.Rows[0].Cells[0].Width to any value doesn't help as well.

I've read this discussion about using one column header for two columns, located here:
http://www.telerik.com/community/forums/winforms/gridview/span-multiple-columns-with-gridview-header.aspx
But not sure that it could be used in my case.

Also, I've took a look at these two articles:
http://www.telerik.com/help/winforms/overview2.html
and
http://www.telerik.com/help/winforms/columngroupsview.html

Could you please advise on how to arrange columns the way I need?

Cheers,
P

SrollControlIntoview WinForms RadPanelBar

Hi,
I have got a problem with the "ScrollControlIntoView" Method of the Radpanelbar control.

After the "radPanelBar1_PanelBarGroupCollapsing" Event, the collapsing Item should scroll into view.
The function should be likely this.

private void radPanelBar1_PanelBarGroupCollapsing(object sender, PanelBarGroupCancelEventArgs args)
        {
            this.radPanelBar1.ScrollControlIntoView(this.radPanelBar1.Controls[this.radPanelBar1.Items.IndexOf(args.Group)]);
        }

but it doesn't work. Please help me.

Winforms Q1 2011

Can you tell me what the possible beta / release date would be for the Winfroms Q1 2011.

I am busy with a multi language app and would see this as a plus in my development. I use a lot of RTL (right to left) languages in my app (like Arabic and Urdu) and some other languages. Controls that support RTL languages (efficiently) are very few.

Some of your competitors claim that they support RTL, but when testing their products, they have failed miserably. When writing to their support teams about problems experienced, the common excuse is - "this or that" has not yet been implemented for RTL languages. Hopefully, you will have a workable solution that supports RTL in the true sense.

Is their any way to test a pre beta version.

Many thanks

Fast and Responsive GridView for data acquisition

I'm evaluating buying the RadControls WinForms for the following use case:

To log millions of messages into a customizable grid GUI (e.g. similar features of Telerik's Win Forms Datagrid).

Since this should be used for logs from specific hardware I'm forced to use as a storage a file or a flat database (I don't want to use SQL server or so).

The gridview shall be customizable and fast on inserting new rows and when grouping/filtering/formatting. All these operations need to be done while the grid collects data on a pace of ~1000 events/second.

Would you recommend your grid for this purpose?

Changing currently selected tab programatically

Hello -

I thought this would be easy enough, and am still sure it must be, but .....

Can anyone post a snippet of:

1) How I would change the currently selected tab in a radribbonbar programatically?
2) Tell me which event gets fired when the selected tab changes?

My situation is that I have a standard windows tab control nested under the radribbonbar control. When the user changes the selected tab on the radribbonbar, I need to change the selected tab on the standard windows tab control as well.

Thanks much -
Jack
