Hello,

many thanks for the quick reply. I figured it out: I was not assigning the variables to the correct ResourceCustomizer.

My only problem now is the message "NaN (it's not a number)". I can't figure out how to replace this.

Any ideas?

Many thanks Mike. Just a question: this work with summaries? Because that's what I need...

I found an easier way to replace the "NaN" string in summary: This is my code and it works like a charm!!!.

If a number is a Double then it checks for the "NaN" value.. if it is replaces with "N/A" and if not puts the original Display Format.

Hope it helps someone!!!

Private Sub CalcManager1_CalculationsCompleted(sender As Object, e As System.EventArgs) Handles objCalcManager.CalculationsCompleted

            Dim i As Integer = 0
            Dim dbl As Double = 0
            Dim strDisplayFormatAs String = String.Empty
 
            With grdWin
                 For i = 0 To .DisplayLayout.Bands(0).Summaries.Count - 1
                        If Not .Rows.SummaryValues(i).Value Is Nothing AndAlso _
                            Not .Rows.SummaryValues(i).Value Is DBNull.Value Then
                            If Double.TryParse(.Rows.SummaryValues(i).Value.ToString, dbl) Then
                                strDisplayFormat= .Rows.SummaryValues(i).SummarySettings.DisplayFormat
                                If .Rows.SummaryValues(i).Value.ToString.Contains("NaN") Then
                                    .Rows.SummaryValues(i).SummarySettings.DisplayFormat = "N/A"
                                Else
                                    .Rows.SummaryValues(i).SummarySettings.DisplayFormat = strDisplayFormat
                                End If
                            End If
                        End If
                    Next
             End With
    End Sub

No, the code I posted is for cell. For Summaries, it would have to be modified.

Your solution is a good one, and probably a lot simpler than mine. But looping through every SummaryValue is probably not the most efficient way to go.

It would be more efficient and simplify the code if you used the SummaryValueChanged event (of the grid) instead of CalculationsCompleted.

Good idea. I will try this :)

Thanks ;)

Hello ,

I am glad to hear that you were able to solve your issue.

Thank you for using Infragistics Components.

Just tested and it works like a charm...

Doing it on the SummaryValueChanged of the grid is way more efficient. Thanks for the tip ;)

The code looks like this now:

 Private Sub grdWin_SummaryValueChanged(sender As Object, e As Infragistics.Win.UltraWinGrid.SummaryValueChangedEventArgs) Handles grdWin.SummaryValueChanged

 
 
            Dim dbl As Double = 0
            Dim strDisplayFormat As String = String.Empty
 
            If Not e.SummaryValue.Value Is Nothing AndAlso _
                Not e.SummaryValue.Value Is DBNull.Value Then
                If Double.TryParse(e.SummaryValue.Value.ToString, dbl) Then
                    strDisplayFormat= e.SummaryValue.SummarySettings.DisplayFormat
                    If e.SummaryValue.Value.ToString.Contains("NaN") Then
                        e.SummaryValue.SummarySettings.DisplayFormat = "N/A"
                    Else
                        e.SummaryValue.SummarySettings.DisplayFormat = strDisplayFormat
                    End If
                End If
            End If
 
 
  End Sub
