[Solved] Change height of a ribbontab (DropDown)

Hi

I adapted the height of a radRibbonBar with (radRibbonBarExpand):

this.radRibbonBar1.RootElement.MaxSize = new System.Drawing.Size(0, 120);
this.radRibbonBar1.RootElement.MinSize = new System.Drawing.Size(0, 120);

And wanted to change the height of the drop-downed tab the same size and tried (radRibbonBarDropDown):

this.ribbonTab1.MinSize = new System.Drawing.Size(0, 20);
this.ribbonTab2.MaxSize = new System.Drawing.Size(0, 50);

but the height stays the same. How is it possible to change this height?

Thank you in Advance

Kind Regards,

Dominik

Auto row-height with multiline cell

Hello,

actually I am testing the RadGridView.

I made a Grid with three columns. One of them as multiline textbox.

So, my problem is to set the row height dynamically with the number of the lines of the multiline cell.

The user should see all the lines of the multiline cell if the cell will be in edit mode.

I have read all the threads about that, but I don‘t find a solution.

Any help from you.

thank you and best regards

RadButtons not rendering the same way in two different tabs.

Hi.

On a form, I am programmaticaly creating radButtons in tow different tabPages. The UI is rendered correctly in the first tab (see "Tab1.png") but not in the second ("Tab2.png"). They are generated the same way:

// For tab 1

RadButton b = new RadButton();

b.EnableTheming = true;

b.ThemeName = new DesertTheme().ThemeName;

b.Name = n;

b.Text = n;

b.Left = 10;

b.Top = (22 * i++);

b.MinimumSize = new Size(ptp1.Width - 40, 20);

b.MaximumSize = new Size(ptp1.Width - 40, 0);

b.AutoSize = true;

b.Padding = new Padding(4);

((TextPrimitive)b.ButtonElement.Children[1].Children[1]).TextWrap = true;

b.RootElement.StretchVertically = false;

b.TextAlignment = ContentAlignment.MiddleCenter;

b.Click += new EventHandler(onBtnRechercheClick);

tt.SetToolTip(b, b.Name);

ptp1.WindowsControl.Controls.Add(b);

// For tab 2

RadButton b2 = new RadButton();

b2.EnableTheming = true; b2.ThemeName = new DesertTheme().ThemeName; b2.Name = n2; b2.Text = n2; b2.Left = 10; b2.Top = (22 * i2++); b2.MinimumSize = new Size(ptp2.Width - 40, 20); b2.MaximumSize = new Size(ptp2.Width - 40, 0); b2.AutoSize = true; b2.Padding = new Padding(4); ((TextPrimitive)b2.ButtonElement.Children[1].Children[1]).TextWrap = true; b2.RootElement.StretchVertically = false; b2.TextAlignment = ContentAlignment.MiddleCenter; b2.Click += onBtnRechercheClick; tt.SetToolTip(b2, b2.Name); ptp2.WindowsControl.Controls.Add(b2);

[Solved] Set single property label font style to bold and value background color?

Hello,

is there any way to set a single property Label font style to bold in the Grid? and is there also a way to set a different background color for the value input field?

I want show the user this property value is required. For this purpose I created a PropertyStoreItemExtended class inheriting the PropertyStoreItem with an added property Required. Now I have to find a way to customize Label and/or Value field in case of the Required property value.

Which PropertyGridEvent or (overridden) Methods can be used for that pupose?

[Solved] Vertical Group Layout

Greetings.

Using the code below, it is possible to set vertical group layout :

RadPanorama1.PanoramaElement.GroupLayout.Orientation = Orientation.Vertical

BUT,

what would be the usage as it disables the scroll ball. I found relevant threads, but It would be helpful for VB.NET developers if you just not provide solutions in C#, but also in VB.NET (I already know C# can be converted to VB.NET, but it isn't comfortable in many cases).

For instance, I edited the relevant thread to create custom Panoroma :

Imports Telerik.WinControls

Imports Telerik.WinControls.Layouts

Imports Telerik.WinControls.UI

Class CustomPanorama

Inherits RadPanorama

Private vScroll As RadScrollBarElement

Protected Overrides Sub CreateChildItems(ByVal parent As Telerik.WinControls.RadElement)

MyBase.CreateChildItems(parent)

Me.vScroll = New RadScrollBarElement()

Me.vScroll.ScrollType = ScrollType.Vertical

Me.vScroll.StretchHorizontally = False

Me.vScroll.StretchVertically = True

Me.vScroll.MinSize = New System.Drawing.Size(16, 0)

Me.vScroll.Alignment = System.Drawing.ContentAlignment.TopRight

Me.PanoramaElement.Children.Add(vScroll)

AddHandler vScroll.ValueChanged, AddressOf vScroll_ValueChanged

AddHandler PanoramaElement.GroupLayout.RadPropertyChanged, AddressOf GroupLayout_RadPropertyChanged

AddHandler PanoramaElement.TileLayout.RadPropertyChanged, AddressOf GroupLayout_RadPropertyChanged

Me.ScrollBarAlignment = HorizontalScrollAlignment.Bottom

End Sub

Private Sub GroupLayout_RadPropertyChanged(ByVal sender As Object, ByVal e As Telerik.WinControls.RadPropertyChangedEventArgs)

If e.Equals(RadElement.BoundsProperty) AndAlso sender = Me.GetCurrentLayout() Then

UpdateVScroll()

End If

End Sub

Protected Overrides Sub OnSizeChanged(ByVal e As EventArgs)

MyBase.OnSizeChanged(e)

UpdateVScroll()

End Sub

Private Sub UpdateVScroll()

vScroll.Maximum = Me.GetCurrentLayout().Size.Height

vScroll.LargeChange = Math.Max(0, CInt((Me.Size.Height - Me.PanoramaElement.ScrollBar.Size.Height)))

If vScroll.LargeChange >= vScroll.Maximum Then

vScroll.Visibility = ElementVisibility.Hidden

Else

vScroll.Visibility = ElementVisibility.Visible

End If

If Me.PanoramaElement.ScrollBar.Visibility = ElementVisibility.Visible Then

vScroll.Margin = New System.Windows.Forms.Padding(0, 0, 0, Me.PanoramaElement.ScrollBar.Size.Height)

Else

vScroll.Margin = New System.Windows.Forms.Padding(0)

End If

End Sub

Private Sub vScroll_ValueChanged(ByVal sender As Object, ByVal e As EventArgs)

Me.GetCurrentLayout().PositionOffset = New System.Drawing.SizeF(0, -Me.vScroll.Value)

End Sub

Private Function GetCurrentLayout() As LayoutPanel

If Me.ShowGroups Then

Return Me.PanoramaElement.GroupLayout

End If

Return Me.PanoramaElement.TileLayout

End Function

Public Overrides Property ThemeClassName As String

Get

Return GetType(RadPanorama).FullName

End Get

Set(ByVal value As String)

MyBase.ThemeClassName = value

End Set

End Property

End Class

But, in this way, we have to create all elements such as tiles programmatically, really difficult and annoying in comparison with visual creation.

How to enable vertical scrollbar for vertical Group Layout ?

Thanks in advance.

[Solved] Disable highlighting of the last selected button

Hi

Is there a way to disable the highlighting of the last selected button?

With:

private void button_changebackcolor(object sender, System.EventArgs e)
{
if(((Telerik.WinControls.UI.RadButton)sender).BackColor != System.Drawing.Color.White)
{
((Telerik.WinControls.UI.RadButton)sender).BackColor = System.Drawing.Color.White;
}
}

it's possible, but that makes problem with my real program, because sometimes I need to highlight a button with yellow and button_changebackcolor overrrides that.

Thank you in Advance

Kind Regards,

Dominik
