TimelineView hours scale, setting the start hour of the day

Hi,

I'm using the timelineview with Timescales.Hours. I would like to set the view so that the first hour displayed in the left side would be the one that has the first appointment of the day.

How can I achieve this in the code (vb.net)?

a) I know that I can set the start date, but can I set the start hour somehow? If I know, for example, that the first appointment is at 14:15, can I set the start hour to 14:00?

b) Or can I scroll to the first appointment of the day, so that the first appointment would be displayed in the left side of the view?

I'm using Telerik UI for Winforms Q3 2014 SP1

Br,
Pirjo

Load on Demand a Hierarchial Relationship with Entity Frame work

I have a simple code first database that I want to load on demand within a hierarchial grid. I have everythign working except I don't know how to cast the results within the RowSourceNeed procedure.

public class Product

{

public int ProductId { get; set; }

public string Name { get; set; }

public int CategoryId { get; set; }

public virtual Category Category { get; set; }

}

public class Category

{

private readonly ObservableListSource<Product> _products =

new ObservableListSource<Product>();

public int CategoryId { get; set; }

public string Name { get; set; }

public virtual ObservableListSource<Product> Products { get { return _products; } }

}

public class ProductContext : DbContext

{

public DbSet<Category> Categories { get; set; }

public DbSet<Product> Products { get; set; }

public ProductContext()

: base("my conn string")

{

this.Configuration.AutoDetectChangesEnabled = true;

}

I setup the child template thusly:

this.radGridView2.RowSourceNeeded += new Telerik.WinControls.UI.GridViewRowSourceNeededEventHandler(this.radGridView2_RowSourceNeeded);

GridViewTemplate childTemplate = new GridViewTemplate();

childTemplate.HierarchyDataProvider = new GridViewEventDataProvider(childTemplate);

childTemplate.DataSource = this.productsBindingSource;

childTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

radGridView2.MasterTemplate.Templates.Add(childTemplate);

Then in the radGridView2_RowSourceNeeded event when I open the row

private void radGridView2_RowSourceNeeded(object sender, GridViewRowSourceNeededEventArgs e)
{ e.ParentRow.DataBoundItem as ??? }

I can see when I run it that e.ParentRow.DataBoundItem is a System.Data.Entity.DynamicProxies.Category_485959... type

See attached.

and that if I could just access the.Products of it then I could iterate and add the rows.

Any ideas how to access? Thanks.

[Solved] GroupRow.MinHeight not work

My grid is set
AutoSizeRows = true;

I just want my rows are a minimum:

private void GridView_CreateRow (Object sender,

Telerik.WinControls.UI.GridViewCreateRowEventArgs e)

{

e.RowInfo.MinHeight = TableElement.RowHeight;

}

This works perfectly but does not work for the group.
So I put:

private void GridView_CreateRow (Object sender,

Telerik.WinControls.UI.GridViewCreateRowEventArgs e)

{

e.RowInfo.MinHeight = TableElement.RowHeight;

if (e.RowInfo.Group = null)

e.RowInfo.Group.GroupRow.MinHeight =

TableElement.RowHeight;

}

That is the property MinHeight Group does not work as it should (equal to
the RowInfo.MinHeight).

How can I solve this?

I'm looking to use RichTextEditorRibbonBar and RichTextEditor for some simple WP functionality in our VB.NET application.

Is there a way of specifying the default folder for File | Open from the Ribbon bar? Can't see anywhere to set it.
Also, would any solution apply to the Save/Save As dialogs. I want to force user to start in a specific folder.

I want to remove that extra control box. When i use normal radform as child form, then no issues.

RadDateTimePicker NullDate Bug

I have a RadDateTimePicker control defined as follows:

datePicker.NullText = "No date...";

datePicker.NullDate = DateTime.Parse("1900-01-01");

When I set

datePicker.NullableValue = DateTime.Today;

datePicker.Value also changes to today.

However, when I set

datePicker.NullableValue = null;

or call

datePicker.SetToNullValue();

datePicker.Value is set to "0001-01-01" regardless of what my NullDate is.

Why is Value not set to NullDate when NullableValue is set to null? How do I get rid of the garbage date, in year "0001"?

Multiple Instances of the Same Form

I have a dock with multiple Document Windows.

I want to open multiple instances of the same form on different document windows. Each form. although the same, needs to contain different data.

Every time I open a second instance of the form on a second document window, the first instance of the form on the first document window disappears. The second instance contains the data from the first instance, when it should be maintaining the data from the second document window.

Is there any way to get around this?
