[Solved] Theme working in design time but not at runtime

I have a base form inherited from RadForm and in the constructor I added the following.

Public Sub New()
MyBase.New()

ThemeResolutionService.ApplicationThemeName = "VisualStudio2012Dark"
Me.ThemeName = "VisualStudio2012Dark"
End Sub

When I open the BaseForm in VisualStudio I can see that the form is "Dark" but when I run the application, the form is not "Dark".
The titlebar font / icons did change from their original look "for example the X close button looks 3D" but they also did not take on the "Dark" theme.

I have tried several of the other themes and they all working at design time but not runtime.

RadTrackBar - Hiding Slider

Hi,

Is there any ability in the RadTrackBar to hide the actual slider? I'm basically looking to use the control just for the tick marks and no visible slider or slide area.

Thanks,
Bob

[Solved] RadGridView and RadHostItem

Hello,
I found some problems trying to use the RadHostItem control to customize the cells of a RadGridView.
I developed a class (MyCell) that derives from GridDataCellElement; in such class, the RadHostItem hosts a RadTextBox control.
In the CreateCell event of the RadGridView, I set the cell tyle as typeof(MyCell).
Everything works fine, the RadTextBox control appears in the Grid cells but, and this is the problem I'd need to solve, when I scroll down the Grid, the RadTextBox controls cover and hide the Column Headers of the Grid.

I'm using RadControls for WinForms Q1 2010 SP2.
As attachment "scroll.JPG" shows what happens.

Could you please help me ? Many thanks in advance
Stefano

The entire source code is:

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)

{

DataTable dtGrid = new DataTable();

dtGrid.Columns.Add("COL1", typeof(string));

dtGrid.Columns.Add("COL2", typeof(string));

for (int j = 0; j < 20; j++)

{

dtGrid.Rows.Add("val_0", "val_1");

}

radGridView1.DataSource = dtGrid;

}

void radGridView1_CreateCell(object sender, GridViewCreateCellEventArgs e)

{

if (e.CellType == typeof(GridDataCellElement) && e.Row is GridDataRowElement)

{

e.CellType = typeof(MyCell);

}

public class MyCell : GridDataCellElement

{

private RadHostItem _RadHostItem;

private RadTextBox _RadTextBox;

public MyCell(GridViewColumn column, GridRowElement row)

: base(column, row)

{

}

protected override void CreateChildElements()

{

base.CreateChildElements();

_RadTextBox = new RadTextBox();

_RadTextBox.Name = "_RadTextBox";

_RadHostItem = new RadHostItem(_RadTextBox);

Children.Add(_RadHostItem);

}

public override void SetContent()

{

_RadTextBox.Text = "flower";

}

protected override SizeF ArrangeOverride(SizeF finalSize)

{

SizeF size = base.ArrangeOverride(finalSize);

float width = size.Width;

float height = size.Height;

_RadHostItem.Arrange(new RectangleF(1f, 1f, width - 1f, height - 1f));

return size;

}

Get Resource ID from EventID Key

I am creating radScheduler resources by creating a EventId where the key is an employee number. Like this:

resource.Id = new EventId([Emp#])

I later need to add an appointment to radScheduler and assign it to the resource who's Id is that of the EventId([Emp#]).

How can I get the ResourceId from the collection where the EventId Key that the resource was created with equals [Emp#]?

Thank you.
