I need to show the search point by adding one pinpoint. do you have some custom search example for openstreetmap?

Please provide some sample code for the openstreetmap.

Thanks,

RadRichTextBox error

Good evening,

I'm keep getting the following error whilst trying to use the WPF RadRichTextBox in the "Word Processing" configuration in VS2010 VB.net 4. It's the latest WPF tools (version 0419).
I dragged and dropped the RichTextBox into my designer window grid and then followed the step by step process. All works and looks fine until I run the app in debug mode.

FileNotFoundException was unhandled
Could not load file or assembly 'System.ComponentModel.Composition, Version=2009.7.8.0, Culture=neutral, PublicKeyToken=13e5ffd4e05db186' or one of its dependencies. The system cannot find the file specified.

System.Windows.Data Error: 40 : BindingExpression path error: 'CaptionButtonsReservedWidth' property not found on 'object' ''MainWindow' (Name='')'. BindingExpression:Path=CaptionButtonsReservedWidth; DataItem='MainWindow' (Name=''); target element is 'ContentControl' (Name='windowButtonPlaceHolder'); target property is 'Width' (type 'Double')

A first chance exception of type 'System.IO.FileNotFoundException' occurred in Telerik.Windows.Documents.dll

When the app runs a dialog window opens trying to find a RadDictionary.cs file.

I have uninstalled and re-installed the Telerik WPF tools and it hasn't solved the problem.

It did originally work but now for some reason it doesn't anymore.

Thank you for your time,

Rob

Save Command

Short question. How can I intercept the save command, i.e. not show the save dialog, but write the image into a database? I tried the ImageToolViewModel, but in there are only tools defined... no save button.

Edit: Found the ImageEditorRoutedCommands.Save
is there a (telerik) best practice to override the command?

Another Edit: Ok there's myImageEditorUI.ImageEditor.CommandBindings ... where I can add a command binding to the save command and set handled = true ... however, ImageEditor seems to be (always) null, even after an image has been loaded.

Thanks for your advice!

I am using your RadGridView with a RadDataPager. I am wondering if vertical scolling is still possible if the data is paged? The problem occurs when i am resizing the window ... The size of the RadGridView is kind of fixed now.

Can you help me solving this issue?

Here my code:

CanUserInsertRows="False"

IsReadOnly="True"

CanUserSortColumns="True"

ShowGroupPanel="True"

AlternationCount="2"

ShowColumnHeaders="True"

RowIndicatorVisibility="Collapsed"

CanUserFreezeColumns="False"

FontSize="11"

VerticalAlignment="Stretch">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding MandantNummer}" Header="{x:Static LocalResources:ResSystemKonfigurationMandanten.Mandanten_ColumnTitle_MandantNummer}" DataType="{x:Type System:String}" Width="25*"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Bezeichnung}" Header="{x:Static LocalResources:ResSystemKonfigurationMandanten.Mandanten_ColumnTitle_Bezeichnung}" DataType="{x:Type System:String}" Width="25*" />

All Day Appointments

How are All Day appointments going to be displayed in the Q2 2011 release. I've read that All Day appointments were implemented, but I don't see anything about it in the ScheduleView documentation.

How to select row in RadGirdView by Id

Hello,
I want to select record in grid using my object ID.
Eg. I have collection of Customers. Each customer has ID, and I have one Customer with I want to select in gird. The problem is that my customer has different reference than customer in RadGrid but the same ID (so SelectedItem doesn't work).
I know that I can first get the customer reference searching my collection (eg. using linq), but there isn't any comparer mechanism to set in RadGridView?
In most cases we override Equals() method on our objects, but sometims data comes from Web Service and we use Add Service Reference option, so we can't have influence on class definition.

Mask modifier don't work

Hi,

the mask modifier does not seem to work for me. I use the following mask (for ICD codes) in a RadMaskedTextInput: ">Lnn.nn". But the '>' character is shown instead of forcing upper case style.

Using no mask

Hi,

the masked text input control has some nice features I would like to use for "normal" text boxes, too. Is there a way to use no mask?

Or to have a mask to allow a variable lengh of text, sth. like "a*" ?
