Hello Mohammad,

Thank you for contacting us.

The implementation in this case very much depends on what is your data source. If your data source is a business object every object can have a property which calculates the net value of its children. By implementing the INotifyPropertChanged your main object can listen for property changes and recalculate that property.

If this is not suitable for you, I would recommend you send me a sample project which will help me provide you with more adequate support.

Let me know If I can be of further assistance.

Regards,
George

Hello George 

I Can't upload my project , so let's try another thing
Project steps :
1- Make new windows form project using visual studio 2012.
2- put new Radgridview on form and change the name to : GVTransactions.
3- Add this code instead of form designer code starting with private sub InitializeComponent:

   
Private Sub InitializeComponent()<br>
        Dim GridViewTextBoxColumn1 As Telerik.WinControls.UI.GridViewTextBoxColumn = New Telerik.WinControls.UI.GridViewTextBoxColumn()<br>
        Dim GridViewTextBoxColumn2 As Telerik.WinControls.UI.GridViewTextBoxColumn = New Telerik.WinControls.UI.GridViewTextBoxColumn()<br>

    End Sub<br>
End Class


5- simply Do as next steps to get my point

1-click on Add item button.
2-click on cell button to add new effect.
3-enter any number to effect percent cell and then press enter.

simply in this event or (any thing you suggest) i want to see summary of effects value column in net effects in parent row , and recalculate all summaries in grid.
 
thank you very much

best regards

Hello Mohammad,

Thank you for writing back.

In this case it is enough to subscribe to the CellValueChanged event of the grid and change the value of the corresponding cell. It will update the summary data:
Private Sub GVTransactions_CellValueChanged(sender As Object, e As GridViewCellEventArgs)
    If e.Column.Name = "eff_Percent" Then
        Me.GVTransactions.Rows(0).Cells("Effects_net").Value = e.Value.ToString()
    End If
End Sub

I also suggest you to take a look at our articles about managing hierarchical data in RadGridView - http://www.telerik.com/help/winforms/gridview-hierarchical-grid-binding-to-hierarchical-data.html

I hope this helps.

George
