[Solved] Applying Telerik Themes to Custom Controls based off Standard WPF Controls

Hi,

I have a custom control based off a standard WPF control:

Public Class SendButton

Inherits System.Windows.Controls.Button

I have also themed standard WPF controls to adopt the current Telerik theme in the Application.Resources of the main app:

<ResourceDictionary

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation">

<Style

TargetType="{x:Type Button}">

<Setter

Property="telerik:StyleManager.Theme"

Value="{x:Static telerik:StyleManager.ApplicationTheme}" />

</Style>

Standard WPF controls successfully inherit the Telerik theme, however custom controls based off standard WPF controls do not inherit the Telerik theme.

How can I theme my custom controls to inherit the Telerik theme? I do not want to the change the inheritance of the custom control to a Telerik control to keep the controls as lightweight as possible (the custom controls do not require the additional features of the Telerik controls). I would like to maintain a consistent user experience over the entire solution and theme my custom controls with the Telerik theme.

Kind regards,
Dave.

SQLite With Open Access Problem

Hello

I have tried to link my data model with SQLite database using configuration file and it works fine but i faced this problem.
When i tried an example of the data model (Classes) and data access layer the in same project it works fine, but when i separated the data model in a class library it always gives this error when i tried to get the Scope:

theObjectScopeProvider1.myScope = GetNewObjectScope();

// The Error  : Could not load file or assembly 'System.Data.SQLite'

I added the reference of 'System.Data.SQLite' to class library as usual and it was working when i convert the project from class library to Console application and invoke the scope.
By the way i tried to load the assembly dynamically from the AdjustForDynamicLoad function but nothing changed:

static public void AdjustForDynamicLoad()

{

Assembly SQLiteAssembly = Assembly.LoadFile(@"C:\Lib\System.Data.SQLite.DLL");

if( theObjectScopeProvider1 == null )

theObjectScopeProvider1 = new ObjectScopeProvider1();

if( theObjectScopeProvider1.myDatabase == null )

{

string assumedInitialConfiguration =

"<openaccess>" +

"<references>" +

"<reference assemblyname='PLACEHOLDER' configrequired='True'/>" +

"<reference assemblyname='PLACEHOLDEZ' configrequired='False'/>" +

"</references>" +

"</openaccess>";

System.Reflection.Assembly dll = theObjectScopeProvider1.GetType().Assembly;

assumedInitialConfiguration = assumedInitialConfiguration.Replace("PLACEHOLDER", dll.GetName().Name);

//assumedInitialConfiguration = assumedInitialConfiguration.Replace("PLACEHOLDEZ", SQLiteAssembly.GetName().Name);

System.Xml.XmlDocument xmlDoc = new System.Xml.XmlDocument();

xmlDoc.LoadXml(assumedInitialConfiguration);

Database db = Telerik.OpenAccess.Database.Get("SQLiteDatabaseConnection",

xmlDoc.DocumentElement,

new System.Reflection.Assembly[] { dll, SQLiteAssembly. } );

theObjectScopeProvider1.myDatabase = db;

}

So, the problem is how to add reference or assembly to the scope.

Thanks in advance.

[Solved] RadClock doesn't show times (after upgrading to the latest Telerik WPF Controls)

As the title implies, I'm having trouble implementing a stand-alone RadClock (no TimePicker involved) control in my WPF app. Before the latest upgrade (my current version is Q1 2011), it worked smoothly (i set the Culture property to get rid of the 'AM/PM' suffixes), but now it just won't show the times from 0:00 to 23:00. My attempt:

<telerik:RadClock HorizontalAlignment="Left" Margin="1,7,0,0" Name="radTimeFrom" Culture="sl-SI" VerticalAlignment="Top" Width="166" Height="145">

<telerik:RadClock.Header>

<TextBlock Text="From" Foreground="White"/>

</telerik:RadClock.Header>

</telerik:RadClock>

Any ideas as to why this thing doesn't work anymore? :)

EDIT: I tried reverting to an older version of the Telerik controls (ver. Q3 2009 SP2) and it works just fine.
EDIT2: But, of course, this is not a solution, because i would still like to have the latest Telerik controls installed, therefore reverting in my case is out of the question. Any info would be greatly appreciated :)

Thanks in advance,
Concerned Developer

The filter is not updating with IQueryable ItemsSource.

Hi, i have a project where i use your RadGridView Control, and pass an IQueryable as the ItemsSource property, but the following is happening:

When i select one of the checkboxes from a columnfilter, all works ok (only the items represented by the selected value appears), but when i unchecked it nothing appears in the gridview (the grid view shows no data [no lines]), but the sql that is passed to the database is ok! (i got it with the SqlServer Profile), the same doesn't happen if i click the clear filter button (all the data is showed in the grid).

[Solved] Problems trying to bind IsExpanded

I'm having issues trying to bind IsExpanded to a bool property

<telerik:RadTreeListView.RowStyle>

<Style TargetType="{x:Type telerik:TreeListViewRow}">

<Setter Property="IsExpanded" Value="True" />

</Style>

</telerik:RadTreeListView.RowStyle>

First I tried using first setter but I would get exceptions.
Then I tried to bind to the second to isolate the issue. This is the exception I get:

Message:

The exception occurs when I'm adding a new item to the IEnumerable source that the RadTreeListView is bound to. It is bound to an observable collection (And the bottom 4 lines of the stack are from the Observable collection)

Is there a better way of binding to the IsExpanded property?

Pasting Multiple Rows & Using ItemsSource

Hello,
I want to copy multiple rows from excel and paste them to my grid. At my first copy action all off the rows are copied. but when i try to copy other rows, blank cells-rows are pasted to the grid. i have checked Clipboard.GetText(); but it is not empty.
I have a grid like below

<telerik:RadGridView AutoGenerateColumns="False" Margin="5" ShowGroupPanel="False" HorizontalAlignment="Left"

Name="DataGridProducts" IsFilteringAllowed="False" ItemsSource="{Binding RelativeSource={RelativeSource Mode=FindAncestor,

AncestorType={x:Type local:PageUpdateProductMainFields}},Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, Path=Products}"

Pasting="DataGridProducts_Pasting" KeyDown="DataGridProducts_KeyDown">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="Malzeme Kodu" DataMemberBinding="{Binding ItemStockCode}" Width="150"/>

<telerik:GridViewDataColumn Header="Malzeme Adı" DataMemberBinding="{Binding ItemName}" Width="150"/>

<telerik:GridViewDataColumn Header="Alış Fiyatı" DataMemberBinding="{Binding IncomePrice}" Width="100"/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

the items source and the events in the grid is below

private DynaList<Product> _Products;

public DynaList<Product> Products

{

get

{

if (_Products == null)

_Products = new DynaList<Product>();

return _Products;

}

set

{

_Products = value;

}

public void AddEmptyProduct()

{

Product tempProduct = new Product();

Products.Insert(Products.Count, tempProduct);

}

private void DataGridProducts_Pasting(object sender, Telerik.Windows.Controls.GridViewClipboardEventArgs e)

{

string nodes1 = Clipboard.GetText();

string[] nodes2 = nodes1.Split(new char[] { '\n' }, StringSplitOptions.RemoveEmptyEntries);

for (int i = 1; i < nodes2.Count(); i += 1)

{

AddEmptyProduct();

}

private void DataGridProducts_KeyDown(object sender, System.Windows.Input.KeyEventArgs e)

{

if (e.Key == Key.RightShift)

{

DataGridProducts.CommitEdit();

AddEmptyProduct();

problem with binding in R2

Hello,

just moved from R1 to R2 and we have a problem with some of the bindings in the GridView
In the UC I have a grid described like this:

<telerik:RadGridView

Margin="6,6,1,4"

CanUserReorderColumns="False"

CanUserDeleteRows="False"

CanUserInsertRows="False"

IsReadOnly="True"

AutoGenerateColumns="False"

IsFilteringAllowed="False"

SelectionMode="Extended"

SelectedItem="{Binding PersoanaSelectata, Mode=TwoWay}"

ItemsSource="{Binding Persoane, Mode=TwoWay}"

Name="radGridViewPersoane"

ShowGroupPanel="False" >

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="Nume"

DataMemberBinding="{Binding Nume}" Width="4*" TextWrapping="Wrap" IsReadOnly="True"/>

<telerik:GridViewDataColumn Header="Prenume"

DataMemberBinding="{Binding Prenume}" Width="4*" TextWrapping="Wrap" IsReadOnly="True"/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

in the vm I have the properties

private VerificarePersoana _verificarePersoana;

public VerificarePersoana VerificarePersoana

{

get

{

if (_verificarePersoana == null)

_verificarePersoana = new VerificarePersoana();

return _verificarePersoana;

}

set

{

_verificarePersoana = value;

Notify("VerificarePersoana");

}

private ObservableCollection<Persoana> persoane;

public ObservableCollection<Persoanaa> Persoane

{

get

{

if (_verificarePersoana.Persoane == null)

{

_verificarePersoana.Persoane = new ObservableCollection<Persoana>();

}

return _verificarePersoana.Persoane;

}

set

{

_verificarePersoana.Persoane = value;

Notify("Persoane");

}

and in persoana I have something like

private string _nume;

public string Nume

{

get { return _nume; }

set { _nume = value; Notify("Nume"); }

}

private string _prenume;

public string Prenume { get { return _prenume; } set { _prenume=value; Notify("Prenume"

); } }



  public void Notify(string propertyName)

        {

            if (PropertyChanged != null)

            {

                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));

            }

        }

My problem is that in R1 when I updated the information in a separate form for one of the entries the information got updated in the grid too. now it doesn't do that. If i sort the items by a column the information shows up correctly again.

Why is that? i would really like to move my solution to R2 but this is really a problem.

Thanks in advance.

need help with radscheduleview raddragdropmanager and radcontextmenu

hi there,

I'm fairly new to Telerik and WPF so I was wondering if someone could help me with a few questions.
My questions are related mainly to RadScheduleView Drag and Drop behavior and also the ability to show a RadContextMenu in a specific area of the radscheduleview control. I have included a sample project and the screenshot below.

1. If I drag a GridViewRow to a schedule view, is it possible to delete that row from my grid after it is dragged to the RadScheduleView ?
2. Is it possible to drag a GridViewRow and drag that row to the GroupHeader and then add a new resource ?
How can I do that?
3. Why does my custom ScheduleViewDragDropBehavior keep calling ConvertDraggedData
even if DragComplete is not actually reached in the OnDragInfo draghandler of my RadGridView ?
4. How can I setup my RadContextMenu to only show up in the GroupHeader to the left (I'm using Timeline View)?
Is it possible to hide ContextMenu when I right click the TimeViewDefinition area ?
