Hi, we have very strange GridViewComboBoxColumn's behaviour. Code is very simple, but we have different result when execute our program on different PC. Normal behaviour should be next:
1) select any item in 3rd row combobox;
2) choose second cell in this row.
3) selected item in 1st column should be selected!!!

But on 50% PC we don't have this, i.e. selected item pull down everywhere. We lose selected item on LostFocus. In debug mode we saw, that debugger comes to GET of Employee.Name property after ComboBox selection changed (on the PC with wrong behaviour). And debugger comes to SET of this property on the PC with normal behaviour. It's hard to believe and to explain. What's wrong with this control?

BUT !!! We don't have any trouble if use common template with ComboBox (i.e. without using GridViewComboBoxColumn) - ex.code3.

Ex.code1: Main Window XAML:

<telerik:RadGridView Name="dGrid" AutoGenerateColumns="False" Height="188" VerticalAlignment="Top">

<telerik:RadGridView.Columns>

<telerik:GridViewComboBoxColumn

ItemsSourceBinding ="{Binding Path=Names, Mode=TwoWay}"

DataMemberBinding="{Binding Path=Name, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"

UniqueName="ClmNames"

>

</telerik:GridViewComboBoxColumn>

<telerik:GridViewDataColumn

DataMemberBinding="{Binding Path=Name, Mode=TwoWay}">

</telerik:GridViewDataColumn>

</telerik:RadGridView.Columns>

Ex.code2: Main window C#:

public MainWindow()

{

InitializeComponent();

_employees = new List<Employee>(){

new Employee {Names = new List<string>{"Ann", "Nata"}, Name = "Ann"},

new Employee {Names = new List<string>{"Elise", "Ivan", "Марк"}, Name = "Ivan"},

new Employee {Names = new List<string>{"Elise", "Ivan", "Марк"}},

};

dGrid.ItemsSource = _employees;

}

Ex.code3: Working template XAML:

<telerik:GridViewDataColumn.CellTemplate> 

<DataTemplate> 

<ComboBox ItemsSource="{Binding Path=ImprovementList}" DisplayMemberPath="refimprovement.name_full" 

SelectedItem="{Binding Path=RecalcManualItem.cfaccimprovementlist, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" 

SelectionChanged="ComboBox_SelectionChanged" /> 

</DataTemplate> 

</telerik:GridViewDataColumn.CellTemplate>

Latitude and Longitude of visible area.

Hi,

Is it possible to get the longitude and latitude of the visible area on screen?

The scenario is the user has zoomed into a city, I want to be able to get the upper left lat and long, the lower right lat and long and then based on those values go to the database and get all the branches in that area.

Simplistic code example.

public void ItemsRequest(object sender, ItemsRequestEventArgs e)

{

var dataContext = page.DataContext as MappingViewModel;

if (dataContext == null)

return;

//var minZoom = e.MinZoom;

var upperLeft = e.UpperLeft;

var lowerRight = e.LowerRight;

var branches = _repository.GetBranches(upperLeft.Latitude, upperLeft.Longitude, lowerRight.Latitude, lowerRight.Longitude);

dataContext.SetBranches(branches, e);

}

The problem is that the e.upperLeft and e.LowerRight latitude and longitude values don't seem to represent what is in the visible area.

Sorry for my lack of understanding, this is the first time I have developed for maps so this may be a really stupid question! :-)

Regards,
Mark

I have Datagrid with large string columns and activated Expression_Dark theme.

<telerik:RadGridView.Columns>
<telerik:GridViewDataColumn Header="Path" DataMemberBinding="{Binding Path=Path}"/>
<telerik:GridViewDataColumn Header="Path2" DataMemberBinding="{Binding Path=Path}"/>
<telerik:GridViewDataColumn Header="Path3" DataMemberBinding="{Binding Path=Path}"/>

Issue of radbook reseting to front page

Hi,

I got a RadTabControl whose itemsource is databinded to an observablecollection and it's itemtemplate has a RadBook. I am also using a RadPager attached to the RadBook in the itemtemplate. Everything with the binding and stuff works fine.

When I have two objects in the collection, two tabs are generated. This is ok and each tab has its RadBook fully loaded as expected. Browsing and fliping the pages are also ok. But, when I move from one tab to the other, the previous tab's RadBook (the one that lost focus) goes back or resets to the front page. The page that was last viewed does not hold.

Why is that?

Thanks

Themes

I couldn't find a better place to put this request or opinion...
I would also like to see the ganttview work with the different themes as I am finding it is the one control in our entire application that you can't read and looks out of place if the user select certain themes, especially expression_dark.

It would be really nice if you could simply

StyleManager.ApplicationTheme = (Theme)themeUserSelected;

InitializeComponent();

and have the ganttview match the rest of the application without having to use downloaded resource dictionaries or workarounds.

Treelist to use Vector image defined in the Xaml

I would like the TreeListView to display a vector image for each Item state instead of a graphics file (png/jpg) and use for example, this path as defined in the Xaml.

Is that possible?

<Window.Resources>

<Path x:Key="MyVectorImage"

x:Shared="False"

Stroke="DarkGoldenRod"

StrokeThickness="3"

Data="M 10,20 C 10,25 40,35 40,17 H 28"

Stretch="Fill"

Width="100"

Height="40"/>

</Window.Resources>

Floating Window Disappears - Microsoft Touch Mouse

Hi,

Is anyone else experiencing issues with the telerik docking floating window when using a Microsoft Touch Mouse?

For some reason, when I use the two finger gesture to expand a docking floating window the window disappears off of the screen. I am then unable to retrieve the window as it is nowhere to be seen or accessed.

Thanks,

Localization of grid column headers not working for hierarchical view

I am trying to localize the column headers using the following code for each of the column in the parent and the child gridviews in a hierarchical view.

<telerik:GridViewColumn.Header>
<TextBlock Text="JudgementCode" telerik:LocalizationManager.ResourceKey="JudgementCode"></TextBlock>
</telerik:GridViewColumn.Header>

This works fine for the main grid, but when I expand a row to see its child gridview, the child table column headers are not localized.

Is there something different I need to be doing for hierarchical gridveiw.

Disable the "drag & drop" of some appointment

Hi!

I've a Scheduler view, which has custom appointments.

I need to have some of these appointment that aren't drag&dropable, depending of a value of one resource of the appointment.

My question is:
On which property of the xaml(in the datatemplate?) can I bind a value which indicate if the current appointment is drag&dropable?
OR
Is there a event in which I enter when I try to do the drag&drop? Where I can cancel if I want the change?

Thank you

ScheduleView
