Hi,

At the moment the appointment window is a dialog box, is it possible to have it be a window so it's not locking down the UI? Something like when editing a recurring appointment, it's not a dialog window.

MVVM Bind Document.IsEmpty

Hi,

I try to have a button disabled when there is no text in my RadRichTextBox by using MVVM. The output I need is HTML and I used to have a HtmlFormatProvider and a TxtDataProvider. I noticed with this that my typing was really slow. The datasource was not updated when I pressed enter (or send, for a chat-like application), this resulted in missing letters in mails or chats.

I wanted to try it without the TxtDataProvider, because I do not need the plain text (only for checking empty). Only thing is the disabled button, I can't check if the HTML is empty, because there always is HTML. I found a way to check if the value of the Document is empty. On DocumentChanged I can check: RadRichTextBox.Document.IsEmpty. But this can't be binded in my ViewModel because Document is not a dependencyproperty.

It would be nice to just bind IsEnabled to a property for the RadRichTextBox, is there a way to do this? Binding to a viewmodel will also resolve the issue. Or is there a way to speed up my RadRichTextBox and the providers?

Thanks,
Rob

WorksheetPageSetup to print on one page

Hello

I'm dealing with the worksheetPageSetup in order to print my worksheet on only one page like it could be done in C# with excel interop like this

PageSetup.Zoom = false;

PageSetup.FitToPagesWide = 1;

PageSetup.FitToPagesTall = 1;

PageSetup.Orientation = Microsoft.Office.Interop.Excel.XlPageOrientation.xlLandscape;

I found

worksheet.WorksheetPageSetup.PageOrientation = PageOrientation.Landscape

but I can't find how to do

PageSetup.Zoom = false;

PageSetup.FitToPagesWide = 1;

PageSetup.FitToPagesTall = 1;

with spreadsheet

Do you know how can I have the same issue with spreadsheet ?

[Solved] Custom Column Value Formatter

Hi

I have a requirement where i need to pass in a custom formatter for values in a GridViewDataColumn. I looked at DataFormatString but i don't think it satisfies my requirement.My requirement is that i need to round the decimal to 4 decimal places but also show a negative sign if the number is negative. For example, if the number is -0.000001, then my grid should show -0.0000 and not just 0.0000. For a positive number, it should just display 0.0000. How do i get this working? Any help is much appreciated.

Thanks

IsExpandedBinding not working as expected

Hello,

I made a sample MVVM project where I have a ViewModel for my nodes:

public class WarehouseItem : INotifyPropertyChanged

{

public event PropertyChangedEventHandler PropertyChanged;

private bool isExpanded;

private string name;

private IList<WarehouseItem> m_items;

public WarehouseItem(string name, int count, bool isExpanded = true)

{

this.Name = name;

this.IsExpanded = isExpanded;

this.Items = (from l_i in System.Linq.Enumerable.Range(0, count)

select new WarehouseItem("SubItem" + (l_i + 1), 0, false)).ToList();

}

public string Name

{

get

{

return this.name;

}

set

{

if (value != this.name)

{

this.name = value;

this.OnPropertyChanged("Name");

}

public bool IsExpanded

{

get

{

return this.isExpanded;

}

set

{

if (value != this.isExpanded)

{

this.isExpanded = value;

this.OnPropertyChanged("IsExpanded");

}

public IList<WarehouseItem> Items

{

get { return this.m_items; }

set

{

if (this.m_items != value)

{

this.m_items = value;

this.OnPropertyChanged("Items");

}

protected virtual void OnPropertyChanged(PropertyChangedEventArgs args)

{

PropertyChangedEventHandler handler = this.PropertyChanged;

if (handler != null)

{

handler(this, args);

}

private void OnPropertyChanged(string propertyName)

{

this.OnPropertyChanged(new PropertyChangedEventArgs(propertyName));

}

I have bound the IsExpanded property to a property of my ViewModel like this:

<telerik:RadTreeListView IsExpandedBinding="{Binding IsExpanded, Mode=TwoWay}"

AutoGenerateColumns="False" ItemsSource="{Binding}">

<telerik:RadTreeListView.ChildTableDefinitions>

<telerik:TreeListViewTableDefinition ItemsSource="{Binding Items}" />

</telerik:RadTreeListView.ChildTableDefinitions>

<telerik:RadTreeListView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}"

Header="Name" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding IsExpanded}"

Header="Is Expanded" />

</telerik:RadTreeListView.Columns>

</telerik:RadTreeListView>

And I was a little bit disappointed when I saw that if you add a node with a ViewModel where the IsExpanded property is already set to True, the node will be first collapsed than expanded.
If you have a lot of nodes and you refresh the state of the nodes frequently, it's really annoying.

Best regards,

TreeListView

Smooth Scrolling with Touch Screen

Hi,

Is there a way to create smooth scrolling between the items with touch screen?
The animation should have acceleration and friction. Like iPhone has.

Someone already asked for this animation two years ago, so i'm wondering if this option was implemented (before I'll try to work with mouse events and calculating the speed delta myself) or is there any solution for this case?

Regards,

RadGroup is re-ordering on pinned and unpinned

Hi,
I am having 5 RadGroup inside RadSplitContainer in my View and data binding is happening through using PRISM and MVVM.
When the RadGroup is getting pinned and unpinned, that particular RadGroup is moving to last in the sequence.
I don't want this behavior. I want the group show in the same sequence as it is declared in XAML.

Please suggest how I can achieved this.

[Solved] Cancel Automatic Selection After Row Deleting

Hellow,

When deleting the selected row in RadGridView, the selection changes automatically to another row. How can I cancel this behaviour ?

There are "Deleted" and "Deleting" events indeed, but they are fired only following a user's deletion. In my case, the deletion is made following a change in the ItemsSource collection.
