Grouping and Sorting Disabled when Binding to Object Sub Properties

[Jaime]

hi,

Sorting and Grouping works well, but I ran into a case where Grouping ans sorting get disabled. 

Here is the code.

<

 

telerikGridView:RadGridView x:Name="SIACMessages" IsReadOnly="True" ColumnsWidthMode="Fill" AutoGenerateColumns="False" >

 

 

 

 

<telerikGridView:RadGridView.Columns>

 

 

 

 

<telerikGridView:GridViewDataColumn DataMemberPath="From.Name" HeaderText="De:" />

 

 

 

 

<telerikGridView:GridViewDataColumn DataMemberPath="Subject" HeaderText="Asunto:"/>

 

 

 

 

<telerikGridView:GridViewDataColumn DataMemberPath="ReceivedDate" HeaderText="Fecha de Recepci¢n:"/>

 

 

 

 

</telerikGridView:RadGridView.Columns>

 

 

 

 

</telerikGridView:RadGridView>

When you use Property.Subproperty, this functionality gets automatically disabled. On the other columns works fine.

This is the object Structure that is being Binded.

 

namespace

 

SIACLookSL

 

{

 

 

public class VisualSIACMail : SIACMail

get { return emailSIAC; }

 

 

 

set { emailSIAC = value; }

 

}

adress.Address = item.Address;

adress.Name = item.Name;

obMail.To.Add(adress);

}

}

 

 

return obMail;

 

}

}

Thanx in advance.

Hello Jaime,

I just checked our online example here: http://demos.telerik.com/silverlight/#GridView/DataSources and everything worked fine when the grid is bound to sub properties.

Hi Vlad,

Thanks for you orientation,

I tried adding the column from code behind and it worked properly, Code as follows.

SIACMessagesGrid.Columns.Add(

new GridViewDataColumn()

 

{

DataMemberPath =

"From.Name",

 

UniqueName =

"From.Name",

 

DataType =

typeof(string),

 

HeaderText =

"Remitente"

 

});

But from the XAML doesn't, I get a Bad Property Error. Code as Follows:

 

<

 

telerikGridView:RadGridView x:Name="SIACMessages" IsReadOnly="True" ColumnsWidthMode="Fill" AutoGenerateColumns="False" >

 

 

 

<telerikGridView:RadGridView.Columns>

 

 

 

<telerikGridView:GridViewDataColumn DataMemberPath="From.Name" DataType="System.String" UniqueName="From.Name" HeaderText="De:" />

 

 

 

<telerikGridView:GridViewDataColumn DataMemberPath="Subject" HeaderText="Asunto:"/>

 

 

 

<telerikGridView:GridViewDataColumn DataMemberPath="ReceivedDate" HeaderText="Fecha de Recepci¢n:"/>

 

 

 

</telerikGridView:RadGridView.Columns>

 

 

 

</telerikGridView:RadGridView>

The problem seems to be in the DataType property. any Guess?

Thanks a lot.

Jaime

Hi Jaime,

The problem in your case is that you are defining the DataType of the Column in XAML - in your case it is String. Silverlight currently lacks the possibility to declare types in XAML. Just remove the DataType attribute from the XAML and everything should work fine. The data type will be correctly resolved by our data binding engine:

<telerikGridView:GridViewDataColumn DataMemberPath="From.Name" DataType="System.String" UniqueName="From.Name" HeaderText="De:" />

Hope this helps.

Kind regards,
