[Solved] Multivalue

[pritesh]

Hello ,

I am using MVVM to bind the nested telerik gridview. Parent gridview contains order number while the child grid contains the order articles.Child grid contains Description , Qty , Price per Qty. This price per qty can be changed at run time so i have put it CellEdit Template of the columns which looks like following.
 <telerikGridView:GridViewDataColumn Header="Price per amount" MinWidth="100"  DataMemberBinding="{Binding Price}"
                                                                        TextAlignment="Center">
                                        <telerikGridView:GridViewDataColumn.CellTemplate>
                                            <DataTemplate>
                                                <TextBox Name="txtPricePerAmount" Text="{Binding Price}"></TextBox>
                                            </DataTemplate>
                                        </telerikGridView:GridViewDataColumn.CellTemplate>
                                        <telerikGridView:GridViewDataColumn.CellEditTemplate>
                                            <DataTemplate>
                                                <TextBox Name="txtPricePerAmount" Text="{Binding Price,Mode=TwoWay}"></TextBox>
                                            </DataTemplate>
                                        </telerikGridView:GridViewDataColumn.CellEditTemplate>
                                    </telerikGridView:GridViewDataColumn>


Now i want to fourth column which multiply price per qty and Qty .I tried to find the solution with the help of IMultiValueConverter but i could not succeed.

Thanks for quick reply.I have gone through CalculatedColumns_2010_061C6D0F example.It is a nice example and serve the purpose. But here one addtional property is used to calculate the total name "total".I can not create any additional properties as i can not change the data model.

Can you please provide me alternative solution ?

Hello pritesh,

In order to provide you with a proper solution, I would need more details about your application. What exactly is your data model ? Is it not possible to add a partial class exposing the necessary property for the calculated column ?

I am using the ado.net entity model.

Hi pritesh,

In this case, the suggestion for adding a partial class is quite applicable. All you need to do is to expose a property similar to the one in the blog post and bind the proper column to it.
