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.

RadMenuItem.Image when selecting a resource image the name is messed up

Take any RadMenu and put a RadMenuItem on it.
Select the RadMenuItem and change the Image property to any resource image (either import a new one or select an existing one.)
The form looks and acts and works correctly but...If you look at the Image property, the name is NOT the name of the selected resource. Instead its a Base-64 Char array...

So the Property window doesnt tell you what resource was selected.

Is there any way to correct this? Any help would be appreciated!
