Hi 

I am having issues setting the RadWindow.Alert window from Code. The method I tried is as follows:


The window size using the above code seems to be 400x600 which is coincidental i.e. it is the size regardless of the Width and Height values used above. I have tried MinWidth and MinHeight as well.

Any ideas?

Hello,

I'm using WPF RadGridView which loades a large database table (about 200000 rows).
I bind the GridView to VirtualQueryableCollectionView object which makes async calls to WCF service in the ItemsLoading  event.
The data from the WCF web service is, of course, retured after the VirtualQueryableCollectionView.ItemsLoading event is ended.
When the data is retured from the WCF web service I load the data to the VirtualQueryableCollectionView using the VirtualQueryableCollectionView.Load method.
The problem is when I drag the scroller, for example, to the middle of the grid it doens't show the loaded data, because the data is loaded a little later after the VirtualQueryableCollectionView.ItemsLoading is finished.
When I scroll to other point in the grid and return back to that place, the data which was loaded earliear is shown correctly.
It seems like it needs to send some notify to the GUI that the data is loaded after the VirtualQueryableCollectionView.ItemsLoading is finished (like INotifyPropertyChanged interface or something).

BTW, when I use sync WCF web service, it works correctly because the data is loaded within the VirtualQueryableCollectionView.ItemsLoading event.

How can I resolve this problem?

Thanks,

Hi,

Is there any reason why the richtextbox TextInput event doesn't fire? Does it have something to do with it hosting a document?

DocumentContentChanged etc events fire. I am just wondering why TextInput doesnt?... mainly for reference purposes.

Thanks,

Rob

I've added a resource file to my WPF application and in it I have:

<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="telerik:RadGridView" BasedOn="{StaticResource {telerik:ThemeResourceKey ThemeType=telerik:Office_BlueTheme, ElementType=telerik:RadGridView}}" />
</ResourceDictionary>

and in App.xaml I have:
<Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Dictionary1.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>


And in a usercontrol I've added a RadGridView; Now the group section and gridline borders are blue but the header remains black.
why the theme dosen't apply to column header?

Hello!

I have a grid with columns and columngroups, which I declare in XAML. According to the time periods of the data, which should be displayed, I have to change to header of the columngroups.

I tried something like ...


... but the colGrp stays null.

How can I achieve this?

Kind regards

Michael

P.S.: I'm new to WPF!

When you run your samples for the Chart control to look at the 3d pie chart, these errors are thrown.  Your code is a pretty simple bind to IEnumerable.  What should I do to avoid this when plugging your charts into my app?

I am trying to resolve an issue with weird behavior on a RadMaskedCurrencyInput control when entering negative values.  I believe you would experience similar issues with other masked input controls. I currently have this control:
<telerik:RadMaskedCurrencyInput />
If you run this and try to enter -500 for example, the textbox does not take in the negative.  You have to type the 500, then the "-" for the textbox to recognize the negative value. 

I have also noticed that if you load the control with a default value, then the negative is recognized when you type it in.
<telerik:RadMaskedCurrencyInput Value="51.64" />

Basically, try this control without a default value and you will see some pretty funky behavior when trying to enter a negative number.

Any feedback will be helpful.
Thanks.

Hi,
I just read in your wpf documentation section to change theme brushes for Metro Custom theme. i.e.

MetroColors.PaletteInstance.MainColor = Colors.Black;
            MetroColors.PaletteInstance.AccentColor = Colors.Orange;
            MetroColors.PaletteInstance.BasicColor = Colors.DarkGray;
            MetroColors.PaletteInstance.StrongColor = Colors.Gray;
            MetroColors.PaletteInstance.MarkerColor = Colors.LightGray;
            MetroColors.PaletteInstance.ValidationColor = Colors.Red;


Can i do the same for other telerik themes like Windows7Theme?
