Help File

Hi,

Is there documentation (chm) for the WPF controls? I could not see any in the downloads section, and there's nothing integrated into VS that I could see.

Do users need to peruse Telerik's online documentation for WPF?

Cheers

Marked Zone Label/Tooltip

Hello Telerik Team,

I am using Marked Zones to display certain event timespans in a datetime based chart.

I need to give the user a way to find out what this event what, basically somehow showing a string to him, which can be accessed from any zoomlevel where the marked zone is visible.

Thus, I wanted to use the tooltip-property of a marked zone, but couldn't get it to show. The OnToolTipOpeing event is also not fired.

What is the best way to accomplish this task, to actually present the user a string together with a marked zone?

best regards

Ulrik

is it possible to expand an OutlookBarItem in dragmode while moving over it? I made some tests with DragDrop-Control, but i had no success. I want to drag an item from a TreeView in OutlookBarItem "A" to a TreeView in OutlookBarItem "B" which is collapsed.

Thanks

Remove flash effect

Hi

when using BusyIndicator on fast running operations you get a flash effect: busyIndicator appears and disappears in a second flashing the user interface. As don't know in advance how long the operation will last, I'm trying to attenuate the effect setting the OverlayStyle completely transparent as follows:

RadBusyIndicator busyIndicator = new RadBusyIndicator();

// make it trasparent to avoid flashing on fast operations

Setter opacitySetter = new Setter(Rectangle.OpacityProperty, 0.0);

Style overlayStyle = new Style();

overlayStyle.Setters.Add(opacitySetter);

busyIndicator.OverlayStyle = overlayStyle; 

// add to layoutRoot children

busyIndicator.SetValue(Grid.RowProperty, 0);

busyIndicator.SetValue(Grid.RowSpanProperty, 3);

layoutRoot.Children.Add(busyIndicator);

I seems that setting OverlayStyle in code has no effect.
What's wrong in the code
A better solution could delaying the control appeareance with an animation effect; how can I do that?

Sincerely
Ivano

RadComboBox select only from the list

Hi,

I use radcombobox with itemSource and I want that the user would select items from the list only and disabled from typing other
characters in it.

In addition, I want that the autocomplete option will be enabled.
I have those properties in my xaml:

<telerik:RadComboBox Grid.Column="3" Grid.Row="6"

IsReadOnly="True" IsEditable="True"/>

but then if the user start type some characterties, he can't delete them.
when I set the IsEditable property to false, it work well, but then it change the control style.

I saw that the first option is working well in the newer telerik dll version, but I don't want to upgrade the all dll. can I upgrade only one control from the new version?
or, how can I change the style of the control that look like IsEditable is true? I use Windows7Theme.
Is ther more idea's or solutions?

Thanks.

Observe-Notify problem

Hi guys, I am new to WPF all together so not strong on concepts.

I have generated RadgridView and based on the selection of the cell in this Radgridview, I want to populate a new RadgridView.

public partial class SummaryTable : UserControl

{

public SummaryTable()

{

this.InitializeComponent();

}

private void MainGridView_SelectedCellsChanged(object sender, GridViewSelectedCellsChangedEventArgs e)

{

IList<GridViewCellInfo> cellList = this.radView1.SelectedCells;

GridViewCellInfo cellInfo = (GridViewCellInfo)cellList.First();

// Initialize MyView object based on cellInfo.Item to capture the details of whole row

}

The problem is how to pass this MyView object to Top-level ViewModel class so that it can initialize the second table that I want to generate based on the MyView object. I was thinking that when Top-level class will get notified about the new MyView object then it will set the DataSource for the second table to populate it.

Please let me know if you have any other suggestions. I am a new player :)

Thanks,
Mark

How do I display records from a sub collection and filter from an external combobox

Hi,

I created a set of LINQ classes, Customers.Memberships.CertificatesUsed

First, I want to display the records from the Certificates collection

I tried the sample code below but it doesn't seem to work

<telerik:RadGridView AutoGenerateColumns="False"

ItemsSource="{Binding Path=Memberships.CertificatesUsed}">

<telerik:RadGridView.Columns> 

        <telerik:GridViewDataColumn Header="Membership ID" 
                           UniqueName = "MembershipID" 
                           DataMemberBinding="{Binding Path=MembershipID}">
        </telerik:GridViewDataColumn>

<telerik:GridViewDataColumn Header="Certificate No"

UniqueName = "CertificateNo"

DataMemberBinding="{Binding Path=CertificateNo}">

</telerik:GridViewDataColumn>


        <telerik:GridViewDataColumn Header="Date Used" 
                           UniqueName = "DateUsed" 
                           DataMemberBinding="{Binding Path=DateUsed}">
        </telerik:GridViewDataColumn>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

How should I bind the grid to the Certificates list?

Next, I want to be able to filter the content of the grid based on the selected Membership ID from a separate combo box.

How do I do it?

Thanks!
