Hi.

In my grid I've got some columns with double values. Some of the values might be null values or Double.NaN resp.
However, in a summary row I need value counts, average and standard deviation of the values - excluding the null values!
How can I customize the grid aggregate functions to achieve this?
I experimented with GridViewSummaryItem.AggregateExpression a bit, but I don't know how to formulate an If-Condition to skip the null value row.
My code so far looks like this:

        Dim avg As New GridViewSummaryRowItem()
        Dim count As New GridViewSummaryRowItem()
        Dim stdev As New GridViewSummaryRowItem()
        For col As Integer = 2 To table.Columns.Count - 1
            Dim row_cnt As New GridViewSummaryItem()
            row_cnt.Name = table.Columns(col).ColumnName
            row_cnt.Aggregate = GridAggregateFunction.Count
            row_cnt.FormatString = "# {0}"
            count.Add(row_cnt)
            Dim row_avg As New GridViewSummaryItem()
            row_avg.Name = table.Columns(col).ColumnName
            row_avg.Aggregate = GridAggregateFunction.Avg
            row_avg.FormatString = "Ø {0:F4}"
            avg.Add(row_avg)
            Dim row_stdev As New GridViewSummaryItem()
            row_stdev.Name = table.Columns(col).ColumnName
            row_stdev.Aggregate = GridAggregateFunction.StDev
            row_stdev.FormatString = "σ {0:F4}"
            stdev.Add(row_stdev)
        Next
        grd_data_.SummaryRowsBottom.Add(count)
        grd_data_.SummaryRowsBottom.Add(avg)
        grd_data_.SummaryRowsBottom.Add(stdev)

Hello dear,

I can save layout for more than one grid view in the same file ??, for example:

i have gv1 and gv2, i want to save layout for all grids in one file so i can do this ?? if yes let me know, thanks.

In winforms Radgridview whenever I need to create a new row I have been generating a class with members for each column like:

Then I create and use it for adding rows like:

My question is two fold:

1. Can I somehow use newRow from above to directly create the row?

2. Instead of created my own class, since all this information is already in the datagrid can I access the field names though a class derived from the datagrid?

I am trying to validate a change to a property from within a propertygrid that requires a password.  I am trying to capture the ValueChanging event for the underlying editor.  If a form is launched from within the event handler and the change is not cancelled, an ArgumentOutOfRangeException ends up being thrown sometime after the event handler returns.  I have attached a simple example that throws the exception.  In it there is a simple Yes/No message box.  If Yes is answered -> Exception is thrown.  Any help is much appreciated.  Thank you

Enum type and simple class edited by the Property Grid.

First, I'm sorry if the question is not at the correct place.

I have an application that uses FiddlerCore4.dll

I use the following to installe Fiddler's certificate:

        public static bool InstallCertificate()
        {
            if (!string.IsNullOrEmpty(certmakerBcCert))
            {
                FiddlerApplication.Prefs.SetStringPref("fiddler.certmaker.bc.key", certmakerBcKey);
                FiddlerApplication.Prefs.SetStringPref("fiddler.certmaker.bc.cert", certmakerBcCert);
            }

            if (!CertMaker.rootCertExists())
            {
                //CLog.writeNoLogInDB("Creating SSL certificate");
                if (!CertMaker.createRootCert())
                    return false;

                if (!CertMaker.trustRootCert())
                    return false;

                FiddlerApplication.Prefs.SetBoolPref("fiddler.certmaker.PreferCertEnroll", true);
                certmakerBcCert = FiddlerApplication.Prefs.GetStringPref("fiddler.certmaker.bc.cert", null);
                certmakerBcKey = FiddlerApplication.Prefs.GetStringPref("fiddler.certmaker.bc.key", null);
            }
            return true;
        }

However, for firefox, I need to import them manually. How can I ensure through code they are also installed in Firefox? Been looking how to do it for a while.

My application needs to be user friendly, so using Fiddler application to generate Root certificates, and then import them in Firefox is complicated for users.

Thanks
