Hi all,

i want to make a ProgressDialog.

User clicks on button "Delete", then ProgressDialog opens and Progress should be shown.

This is my code for the dialog class:

Public Class ProgressDialog

Public Property MessstelleItems As New List(Of tblMessstelleVerzeichnisNeue)

Public Property ZahlerItems As New List(Of tblZahler)

Public Property MessstellenPage As MessstellenPage

Public Property ZahlerPage As ZahlerPage

Private _ctx As EnergieManagementDataContext

Public Sub New(ByVal ctx As EnergieManagementDataContext)

' This call is required by the designer.

InitializeComponent()

_ctx = ctx

' Add any initialization after the InitializeComponent() call.

End Sub

Protected Overrides Sub OnShown(ByVal e As EventArgs)

MyBase.OnShown(e)

DoWork()

End Sub

Private Sub DoWork()

RadProgressBar.Minimum = 0

If MessstelleItems.Count > 0 Then

RadProgressBar.Maximum = MessstelleItems.Count

For Each item In MessstelleItems

Dim index = MessstelleItems.IndexOf(item) + 1

ProgressRadLabel.Text = "Lösche Messstelle " + index.ToString() + " von " + MessstelleItems.Count.ToString()

RadProgressBar.Value1 = MessstelleItems.IndexOf(item) + 1

Me.Refresh()

Dim tmp As New List(Of tblMessstelleVerzeichnisNeue)

tmp.Add(item)

MessstellenPage.CurrentMeasuringPoints = (From p In _ctx.tblMessstelleVerzeichnisNeues.ToList() Join r In tmp On p.MessstelleVerzeichnisID Equals r.MessstelleVerzeichnisID Select p).Distinct().ToList()

MessstellenPage.DeleteCurrentMeasuringPoints()

Next

Else

End If

End Sub

End Class

The deletion progress works fine. Only the Progressbar isnt displayed.

ProgressDialog is started as a modal Dialog:

Using dataContext = New EnergieManagementDataContext

Dim dlo As New DataLoadOptions()

dlo.LoadWith(Of tblMessstelleVerzeichnisVersion)(Function(r) r.tblMessstelleVerzeichnisZeiches)

dlo.LoadWith(Of tblMessstelleVerzeichnisVersion)(Function(r) r.tblMessstelleVerzeichnisMessbereiches)

dlo.LoadWith(Of tblMessstelleVerzeichnisVersion)(Function(r) r.tblMessstelleVerzeichnisStorungsbereiches)

dlo.LoadWith(Of tblMessstelleVerzeichnisVersion)(Function(r) r.tblMessstelleVerzeichnisVersionZahlerKanals)

dlo.LoadWith(Of tblMessstelleVerzeichnisVersion)(Function(r) r.tblMessstelleVerzeichnisVersionVerantwortliches)

dlo.LoadWith(Of tblMessstelleVerzeichnisVersion)(Function(r) r.tblMessstelleVerzeichnisAreal)

dlo.LoadWith(Of tblMessstelleVerzeichnisVersion)(Function(r) r.tblDokumentes)

dlo.LoadWith(Of tblMessstelleVerzeichnisVersionZahlerKanal)(Function(r) r.tblZahlerKanal)

dlo.LoadWith(Of tblZahlerKanal)(Function(r) r.tblZahlerVersion)

dataContext.LoadOptions = dlo

Dim progress As New ProgressDialog(dataContext)

items = RadGridViewMessstellen.SelectedRows.Select(Function(c) CType(c.Tag, tblMessstelleVerzeichnisNeue)).ToList()

progress.MessstellenPage = Me

progress.MessstelleItems = items

progress.ShowDialog()

End Using

No need to check DialogResult, just for blocking thread stepping out of the using block.

Any suggestions why the ProgressBar isnt updated when function runs.
When work is completed the RadProgressBar shows the full Progress.

thx

Get current filename

Hi,

Is there a way to get the filename of the currently opened document when the Open dialog is used from the ApplicationMenu button group? I want to display current filename in the form caption.

Also, is there anyway to force RichTextEditor to ONLY use docx files (ideally looking to remove the other buttons from the Application menu).

Regards,

Lee.

If you scroll the scroll bar up and down, the contents of the property grid goes all wonky where the content just start to bounce and the scroll gets all mess up. It gets to the point where the property grid contents moves all the way to the top and leaves an bunch of empty space in the bottom. I have attached a screenshot of it. I need a solution for this, because i have a product that needs to ship.

Thanks,
Jerome.

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.

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?

RichText Ribbon Folder Locations

Hi

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.

Regards,

Lee.
