I'm having a problem with the multi line mode of the RadTextbox.

If I drag a new RadTextbox onto a form and then change the multiline property to true then the textbox flickers a lot, VS.NET 2005 uses lots of CPU and after a while VS.NET crashes.

This happens even when the project contains just a single form and that form has a single control.

I'm still evaluating the RadControls for WinForms, but this issue is proving a bit of a showstopper.

Theming to rotate a control

Hi
The effect I wish to achieve is to have a user control which, for example hosts a tree control, but the tree can be rotated round (top to bottom or left to right) to reveal a property grid on which properties for the tree can be set. In other words for it to look like the tree control has a property grid "stuck" to its reverse side. I hope this makes sense.

I was wondering whether the presentation framework could be used to achieve this.

Best regards

Scroll Buttons

Is there anyway to put a left scroll button on the left end of the tabstrip and a right scroll button on the right end of the tabstrip instead of having the buttons together, positioned on the right side or the left? So if someone clicks on the right button, the tabs will scroll to the right and bring up the next set of tabs, and the same would happen if they click on the left button. All I am trying to do is if I have 2 sets of 5 tabs. If the 1st set of 5 tabs display when my Windows form comes up, and the user clicks on the left arrow button, the 1st set of 5 tabs will scroll to the left and the next set of 5 tabs will appear. I would like to see a left or right animated scrolling affect of the tabs based on which buttons are pushed. Any suggestions to make this happen???

Conditional formatting on invisible columns

Hi,
I have a radgridview where I am using conditional formatting.
The column I want to use for conditional formatting I want to hide from the user, as they do not need to see it. But if I set the column to be invisible, all the conditional formatting is ignored. I have tried making it visible and setting the width of the column to 0, but the column will not shrink to lees than about 3 pixels.

Is there a way I can achieve this?

Thankyou

Radio button control ??

Hiya,

Am I blind or is there no radio button in the rad winforms controls ?? Or do I have to use a checkbox control and change a setting to get it to look (and behave) like a radio button ??

The demos even have radio buttons in them but I can't find the control that implements this.

Help !?

Prevent a node from being selected.

Hiya,

I'm currently evaluating the controls and I like what I see so far.

I'm testing out the RadTreeView and for the life of me, can't find anything that would easily let me prevent a node from being selected. There is a BeforeSelect event that I handle but that doesn't have a Cancel property in the RadTreeViewEventArgs.

In the MS TreeView, you simply set e.Cancel = true and done, the new node doesn't get selected.

Any suggestions would be greatly appreciated.

Cheers,
Sylvain

Refresh Problem

Hello
I might be doing something wrong with Calendar.. but I really do not know waht.
I want to show some elements (dates) highlighted: All are introduced in array. And I copy/paste& modify the demo of "Element Render" to do it.
But the problem is that after that, the calendar is like Not Enabled, but when I minimize the application and click to maximize again, it renders and is enabled, or ready to click. Is like there is a final "refresh" or "invalidate". to make a final redraw...

(BTW I suppose that this can be done with Specialdays... but I get problems on how to create the template... I havent found a proper example about how to inicialzate the new RadHostItem (control)... What control...is not the calendar itself.

Thanks. And bare with me... its my first day with the controls....

--------------------

Private Sub RadCalendar2_ElementRender(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.RenderElementEventArgs) Handles RadCalendar2.ElementRender

'If Me.DatesList.SelectedItem Is Nothing Then

' Return

'End If

'Comprobar que e.Day.Date esta en la luista

'Try/Catch

Dim ProcessOK As Boolean

Dim idx As Integer

Try

ProcessOK = False

If Me._CALEN_DatesSet IsNot Nothing Then

For idx = 0 To Me._CALEN_DatesSet.Length - 1

If Me._CALEN_DatesSet(idx).Equals(e.Day.Date) Then

ProcessOK = True

Exit For

End If

If ProcessOK Then

' e.Element.Text = e.Day.Date.Day.ToString ''Me.radTextBox1.Text

e.Element.DrawFill = True

If Me._CALEN_cellBackColor = Color.Empty Then

_CALEN_cellBackColor = e.Element.BackColor

End If

e.Element.ForeColor = Color.Black

e.Element.BackColor = Color.Orange

e.Element.BackColor2 = Color.Yellow

' e.Element.BackColor = _CALEN_cellBackColorSEL 'CType((CType(Me.ColorList.SelectedItem, RadComboBoxItem)).Value, Color)

e.Element.Invalidate()

Else

If _CALEN_cellBackColor <> Color.Empty Then

e.Element.BackColor = _CALEN_cellBackColor

End If

If Not (TryCast(e.Element, Telerik.WinControls.UI.CalendarCellElement)).Selected Then

e.Element.DrawFill = False

Else

TryCast(e.Element, Telerik.WinControls.UI.CalendarCellElement).Selected = True

e.Element.DrawFill = True

End If

Catch ex As Exception

My.Application.SendError(ex, "Error", ErrorReport.MessageImage.Denied, " ")

ProcessOK = False

Finally

End Try

End Sub

Hello everyone,
Anyone knows or have already worked on integrating a Telerik RAD Control Panel Bar with eDeveloper tool from Magic Software ?
For those who worked with the WinForm RadCotrol panel bar from Telerik, is there a COM or API interface that we can call from a third party application ?
Can it be compiled as an ActiveX or So ?

Any information will be appreciated

Thanks in advance
Pierre

Binding to a Tag in a listBox

I have a busniess Object that I am currently binding to the a RadListBox.

Is there a way to set the Tag of the RadListBoxItem to the BO while binding?

If not does anyone have a better suggestion the a foreach loop and comparing the id (from the value field of the bind) to get the BO of the selection?

Thank you
