Hi,

we have an encoding problem in a autocompletenbox. As you can see on the attached file all "ä", "ü", "ö", "ß", are something like
a "?". We bind a txt-file to the autocompletebox.

using (StreamReader reader = new StreamReader(file, System.Text.Encoding.UTF8))

{

string line;

Int32 i = 0;

while ((line = reader.ReadLine()) != null)

{

i++;

string[] tmp = line.Split(';');

vartab.Add(new Vartab(tmp[1], tmp[0], i));

}

How can we solve this problem?

Thanks a lot

DropDownContent closes every time

I'm using DropDownButton in TabControl TabItem header with UserControl as DropDownContent.
When DropDown opens and i'm clicking on UserControl elements for example trying to resize OutlookBar or clicking other elements - DropDown always closes.
This problem does not show itself when using DropDownButton on clear Form as usual, but not when in TabItem header as Style.
Also i have Rotation problems. You can see that UserControl in upper ToggleButton is rotated like a crazy.

Here is Window xaml:

DragDropManager events and KeyStates

As I can see during debug, Telerik.Windows.DragDrop.DragEventArgs has a private field eventArgs which has a field KeyStates. But since Telerik DragEventsArgs hide eventArgs I cannot access KeyStates property.
How am I supposed to figure out if any modifier keys were pressed at the moment of any DragDropManager's events?

SettingsPaneView - Conditional

I'm using the StyleSelectors_WPF example. I'm able to conditionally set both the shape and the connector. However, I'd also like SettingsPaneView to be set based on the ShapeType I've selected. Do you have an example of how to do this?

I'm currently using this style for everything. However, it should only apply to my GroupNode where I have ID and Description. Now, when I have a PersonNode, I need it to display ID, FirstName and LastName fields. Thanks in advance for your help:

<Style TargetType="extensions:SettingsPaneView">

<Setter Property="Template">

<Setter.Value>

RadMap - Cannot bind to Geo_Bounds property of rad map control

Hi

I am unable to bind to the Geo_Bounds property of the rad map control.

If that's not possible, would it be possible to calculate the NW and SE Bounds of the map based on the Center and Zoom level (binding works on these 2 properties !!) of the rad map control ?

Thanks,
Sai Dhalli

Tips on how to create charts (any advice appreciated)

Hi!

I'm trying to figure out if ChartView can be used to achieve charts similar to shown in following screenshots:

http://bittinikkari.com/charts/chart1.png
http://bittinikkari.com/charts/chart2.png
http://bittinikkari.com/charts/chart3.png

Should I use ScatterPointSeries or is there a more suitable type?

Also I would be more than happy if you could give me some pointers on how to proceed implementing these.

I'm using UI for WPF 2013 SP3 but I should receive latest version any time now.

Thanks in advance!

How to reset RowStyle to default?

In my GridView I color rows differently based on the current value of a Combobox column. Each change of the combobox value triggers the PropertyChanged event of the business object.
This works just fine as long as I return one of my own styles in SelectStyle. The row gets correctly drawn using that style.
The problem is, that I want to reset the row style to default (= no style) for one particular combobox value. In this case SelectStyle returns base.SelectStyle(item, container) which is always null (= OK). But the row remains drawn using the previous style although the PropertyChanged event is correctly triggered. If I force the UI to recreate the UI controls of that row (by manually resizing the window), the row is drawn correctly.

What am I missing?

Can I force a redraw of that row to remove the previous style other than by triggering the PropertyChanged event?
I could create my own "Empty Style", but this is what I want to avoid. Any ideas?

Thanks for any help.

[Solved] Group Order

Is there a way to control the Order of the groups shown? It seems to be Alphabetic right now.

I included my XAML and a screenshot for reference. I will probably just rename "Admin" to something else which will do me for now but as my app grows I can see this being an issue.

Thanks,

<telerik:RadTileList x:Name="AppLaunchPad"

GroupTemplate="{StaticResource GroupTemplate}"

ScrollViewer.HorizontalScrollBarVisibility="Visible"

cal:Message.Attach="[Event SelectionChanged] = [Action OpenDoorway($eventArgs)]">

<telerik:Tile x:Name="PendingAuthTile"

TileType="Single"

Group="Authorizations">

<Grid>

<TextBlock Text="Pending"

<TextBlock x:Name="PendingAuthCount"

isEditable property in app.xaml and Localization

Hi,
Let's say I have a RadGridView and want to localize it... then I use CustomLocalization and everything is working as everyone expected... now the problem is when I style the RadComboBox in app.xaml ((without key, cause I want it to apply to every RadComboBox)) like this :

<Style TargetType="telerik:RadComboBox">
<Setter Property="IsReadOnly"
Value="True" />
<Setter Property="OpenDropDownOnFocus"
Value="True" />
<Setter Property="IsEditable"
Value="True" />
</Style>

And after that the gridview filters won't changed their strings... they work and ComboBox items in filters have proper strings(localized strings) but the selecteditem in ComboBox has not changed!!!!
the problem is with IsEditable, because after I delete it, it shows well localized strings...
if I have to bring any more information, please tell me... and finally thanks for the great components!
