Exception while using RadSpreadsheet

[Ishita]

Hello,
        I get this Exception only sometimes while i run my silverlight 5 project.
" The invocation of the constructor on type 'Telerik.Windows.Controls.RadSpreadsheet' that matches the specified binding constraints threw an exception."
Code is here:

<Grid>
                   <Grid.RowDefinitions>
                       <RowDefinition Height="*"/>
                       <RowDefinition Height="25"/>
                   </Grid.RowDefinitions>
                   <telerik:RadSpreadsheet  Grid.Row="0"
                                            x:Name="radSpreadsheet"
                                            AllowDrop="True" MinHeight="100"/>
                   <spreadsheetControls:RadSpreadsheetStatusBar Grid.Row="1" VerticalAlignment="Bottom" RadSpreadsheet="{Binding ElementName=radSpreadsheet, Mode=OneTime}" />
               </Grid>

Please note that i am using Telerik Dll Version : 2014.1.224.1050

Hello Ishita,

Such errors are pretty common in Silverlight applications and ultimately may have nothing to do with the XAML in the view. You could set the Break when CLR exception is thrown option in Visual Studio to see if you will receive an error with more information on the cause for this. 

Let me know how that goes.

hi i have a similar problem...however i do not agree with the response since it is only cause when i add the <telerik:RadSpreadsheet /> tag in the xaml code ... when i comment it out i get the following error: Exception thrown: 'System.Windows.Markup.XamlParseException' in PresentationFramework.dll
Additional information: 'The invocation of the constructor on type 'Telerik.Windows.Controls.RadSpreadsheet' that matches the specified binding constraints threw an exception.' Line number '350' and line position '19'.

the spredsheet control is ok and visible when embedded in a tabcontrol but give this error when i run the program...are there any solutions ...any help on resolving it...

Hi, I found a solution by adding a reference to the Telerik.Windows.Documents.Core DLL.

Hello Burt,

The reference to the Telerik.Windows.Documents.Core.dll assembly is among the required assembly references for RadSpreadsheet to work properly. Indeed, if this reference is missing, an exception like the described one will be thrown.

Hi,

For some strange reason, after I load data into the WPF spreadsheet, everything is fine, I can even access the tabs and the data will show, but when I click on any cell or a button on the window where the spreadsheet is, all the data disappears.Is this a normal behavior and how can I force the spreadsheet to retain the data that it got from the external spreadsheet that was loaded into it....Thanks.

How about the WPF Browser App.  Followed and included all resources -- still.... bang!

System.Windows.Markup.XamlParseException: ''The invocation of the constructor on type 'Telerik.Windows.Controls.RadSpreadsheet' that matches the specified binding constraints threw an exception.' Line number '20' and line position '5'.'

Hi,

Could you please share more information on which application you use and how you use it? Is it the click-once demo application? Have you installed it on the machine or you are building the source code for it?
