I am using 2014.2.729.45 RadOutlookBar as a navigation tool in my wpf app.  there are 8 menu items.  I have set active items count = 5. and my selected index is bound to my view model.

If increase, via the app when running, my active items count to 8 (showing all options), and I click on ANY outlookBarItem, then the correct menu appears.

Interestingly, if I say keep the active items count to 5 and I have 3 items in the small bar across the bottom I get very strange behavior.  so my description let's say there is Item1 thru Item 8.

Item1 thru Item5 are showing
Item6 to Item8 are in the bottom bar, small icon section.

If I click on icon for Item6, the viewmodel registers Item6 clicked.
If I click on icon for Item7, the viewmodel registers Item7 clicked, and then Item6 click. - so item 6 appears
If I click on icon for Item8, the viewmodel registers Item8 clicked, and then Item7 click, then item6. - so item6 appears

so you can never get to item7 and item8 to show, unless you make all items active.

Hello,

While trying to implement the OutlookBar as a container in Prism tutorial (http://docs.telerik.com/devtools/wpf/controls/radoutlookbar/how-to/How_to_Use_RadOutlookBar_as_a_Container_in_Prism_Application.html), the headers do not appear as the tutorial shows. 

I am following the first guide where it adds a header by adding a member, ItemHeader, to the view.  The OutlookBar is set with the DisplayProperty = "ItemHeader", but upon execution, the application does not show the header.  If the horizontal bar is dragged down, the items are minimized and can be read.  So, it appears that the header is set, but is not being displayed properly while not minimized.

I'm assuming this is a simple binding error, but I'm not sure how to proceed.

Hi.

I have a custom appointment with some additional properties. When I change these properties I update appointments End time and Subject, but I see the changes only after I click on OK button. Calling OnPropertyChanged brings no effect. How can I update the UI in the edit dialog, so users can see the changes?

I have a DocumentHost with some Panes bound to a PaneGroup. Everything works well, except when I want to Drag a Pane for Docking it, as soon as I grabbed the tab and want to drag it, an error message "System.ArgumentException was unhandled / Message: This pane cannot be removed from parent, because it doesn't have one!" appears. What is my mistake here?
Thanks for your support :)
Best regards

Hi,

 

I cannot figure out the syntax to bind an ADO.NET DataTable to a Rad Combobox. Can you please help me by posting some source code on how to accomplish the following task:

 

 I have a DataTable fo countries that has an id column and a name column. I want to show the country name in the combo box but when an item is selected in the combo box, I want to return the id. This is a very common task in asp.net and win forms but I cannot figure out how to do this task using the rad combo box.

 

How would I accomplish something like this using the rad combo box?

 

DataTable dt = GetCountries();

This.cboCountries.DataText = “Country”;

This.cboCountries.DataValue = “id”;

This.cboCountries.DataSource = dt;

This.cboCountries.DataBind();

 

…

// get the selected id in the combo box

Int id = this.cboCountries.SelectedValue;

 

Can you please post the correct syntax to accomplish this task using the rad combo box.

 

Thanks for the help!

Here's what I'm trying to accomplish: I have an app that needs to show the user's current location on a map (determined using an attached GPS puck.  The library I'm using provides me the latitude, longitude and accuracy (in meters).  I will also want to place other pins on the map (lat, long only).  I want to display a dot on the map that represents the lat/long, with a circle around it, the width of which displays the accuracy of the reading.

So, I will have an observable collection of objects that have lat, long and accuracy.  I've been trying to follow this page in the documentation:

http://docs.telerik.com/devtools/wpf/controls/radmap/features/visualization-layer/data-binding.html

but this is pixel-based sizing.  I want the ellipse I draw to be a certain height/width determined by a distance on the map.  I have the radius in meters, but I also have a function that will convert it in to a value that represents the degrees of latitude/longitude, which works in the EllipseData object.  However, since I'm databinding, the EllipseData object can't be used in the items template (not a Dependency object) and even still, the properties for width and height can't be bound as they aren't dependency properties.

How can I specify a width/height of a data-bound ellipse in the information or visualization layers in meters (or degrees)?  A related question that may be the solution is this: how can I determine the scale of the currently displayed map view-port?  I could certainly use a value converter or attached property or something to figure out the pixel width from there (though I'd prefer a simpler way).

Thanks in advance!

I dont find missing values property for Scatterlineseries. Is it there only for HTML? My requirement is to interpolate the missing points in scatterlineseries and after interpolation is there a way to get the interpolated value.

Hello,

I'm using xaml, view model and validation rule in C#

The RadDatePicker has default validation for any invalid date. 

In my xaml, I have my own validation rule for RadDatePicker and RadTimePicker with this Style of my ControlTemplate to display the error. (please see the xaml code below the for the Control Template Style and my validation rule)

We allow the user to put nothing or empty string in the DatePicker unless we set it to mandatory that will use our validation rule to output a customized error style and message.In our validation rule, if we want to raise the error, it will use this code "return new ValidationResult(false, ErrorMessage);" However, since the default validation of RadDatePicker or RadTimePicker, it still set show the default error even the validation rule switches off the validation with this line  "return new ValidationResult(true, null);"

 Is there way I can disable the default behaviour and implement the custom behaviour I have?

Thanks.

Jason

Hello,

Can i change the RadWaterMarkTextBox, used by the AutoCompleteBox, by an other TextBox with ControlTemplate?

Does someone have an example?

I am trying to set a gridview filterdescriptor in xaml. 

The filterdescriptor looks like this: 


The idea is that gridview A automatically filters according to what is selected in gridview B. 

The full error is as follows:

System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:Path=Name; DataItem=null; target element is 'FilterDescriptor' (HashCode=61845703); target property is 'Value' (type 'Object')


Any ideas? I'm happy to post more code, just let me know what other information would help.
