Hi,

i add some Messages to a RadListBox in codebehind, using a Backgroundworker. If i start my application all ist fine.
But if i cklick on a button which starts the void again, i get all messages twice.

How can ein clear or remove all the items of my RadListBox before i start again?

radlistbos.Items.Clear(); - does not work

Or is there a  way to clear the Backgroundworker ReportProgress?

Thanks a lot
Best Regards
Rene

Hi,

I have applied theme in App.xaml file as per following.

<Application x:Class="MainWindow"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:telerik="telerik"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.Input.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.Navigation.xaml"/>
                <ResourceDictionary Source="/Accumatch.TaxPayment;component/Themes/Styles.xaml"/>
                <ResourceDictionary Source="/Accumatch.TaxPayment;component/Resources/Resources.xaml"/>
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colors.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>         
    </Application.Resources>
</Application>

I have got applied theme in all control in window instead of GridViewCheckBoxColumn of RadGridView.
I also got applied theme style in Header checkbox of RadGridView.

I have put GridViewCheckBoxColumn in RadGridView as per following.

 <telerik:GridViewCheckBoxColumn DataMemberBinding="{Binding Cleared}" Width="75" IsReadOnly="True" IsResizable="False"
                                                        IsFilterable="False" IsSortable="False" IsGroupable="False">
                            <telerik:GridViewCheckBoxColumn.Header>
                                <CheckBox x:Name="chkHeader" Click="CheckBox_Click" Content="Cleared" Foreground="Gray" HorizontalAlignment="Center"/>                                
                            </telerik:GridViewCheckBoxColumn.Header>                           
                        </telerik:GridViewCheckBoxColumn>

So I want to get style of GridViewCheckBoxColumn in all rows as like Header Checkbox as per attached image in RadGridView.

Any help will be much more appreciated.

Hello,

I want to drag items from the Explorer (i.e. files) to wpf controls. But I have no idea how to set the drop preview line and the drag tooltip.

Is there a way to achieve this.

Thanks in advance.

I have a RadGridView that contains a HierarchyChildTemplate creating another RadGridView for each item in my collection. The collection is of ClassA objects and ClassA contains a collection of ClassB objects and an identifier. I would like to share columns across all the children RadGridViews. ClassA is essentially a grouping of ClassB objects where I can perform some validation among other things. This is what I would like the grid to look like 

+ Instance of Class A
    b.A     b.B       b.C
    b.A     b.B       b.C
+ Instance of Class A
    b.A     b.B       b.C
    b.A     b.B       b.C

A treelistview almost does what I want but my tree is only one level deep and I would need a way to style the root parent row differently. I was hoping you might have some suggestions for how I can accomplish this. Thank you

Hello everyone! How can I position the layout of controlpanelitem.content?

We want to style the RadDocumentPane Header according to the style of our custom RadTabItem Style which uses the Corner Radius Property. For an example please take a look at the screenshots below.

Please let us know, if anybody has an idea or knows a solution for solving the Problem. 

Hi,

When i press the Decimal key in Excel its readed as a decimal separator (in spanish culture a comma) but the radspreadsheet control inserts a dot instead.
Is there any way to make radspreadheet work this way?

Hello,

when you try to reset the UseGlidingConnector property with a connection attached, an exception is thrown.
How can I (programmatically) find the corresponding connection, detach it from the gliding connector and attach it to a normal connector?
And for Undo-Functionality: how can I re-attach it to the gliding connector when performing an undo?

Dear Telerik Team!

I use templates for my appointments. There are few of them and each appointment template uses its own tooltip template. When I hover mouse over appointment, correct tooltip is displayed, but if the mouse hovers an edge of the appointment and the mouse cursor changes into resize "mode" (NS cursor), displayed tooltip is incorrect. Is there anything I can do about it?

Very best regards and thank you!
