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

public class stopCreationRow
   {
       public string shipper, consignee, zip;
   }

 

Then I create and use it for adding rows like:

private void radButton35_Click(object sender, EventArgs e)
  {
      stopCreationRow newRow = new stopCreationRow();
      //throughout the code set the various fields as needed
      newRow.consignee = "person";
      newRow.shipper = "new shipper";
       
      //then transfer everything to the proper cells
      GridViewDataRowInfo dataRowInfo = new GridViewDataRowInfo(this.stopCreation_grid.MasterView);
      dataRowInfo.Cells["consignee"].Value = newRow.consignee;
      dataRowInfo.Cells["shipper"].Value = newRow.shipper;
       
      //finally create the row
      stopCreation_grid.Rows.Add(dataRowInfo);
       
  }

 

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.

public enum EnumeratedProp {
   FirstItem,
   SecondItem,
   ThirdItem
}
 
public class TestProps
{
   [DisplayName("Formula Lock Active")]
   [Description("Indicates whether custom formulas can be locked to prevent editing")]
   public EnumeratedProp TestProp { get; set; }
}

 

Form Code

public partial class TestPropsForm : Form
{
   public TestProps tstProps = new TestProps();
 
   public TestPropsForm()
   {
      InitializeComponent();
      radPropGrid.SelectedObject = tstProps;
   }
 
   private void radPropGrid_EditorInitialized(object sender, Telerik.WinControls.UI.PropertyGridItemEditorInitializedEventArgs e)
   {
      if(e.Item.Name == "TestProp")
      {
         e.Editor.ValueChanging += TestProp_ValueChanging;
      }
   }
 
   private void TestProp_ValueChanging(object sender, Telerik.WinControls.UI.ValueChangingEventArgs e)
   {
      e.Cancel = (MessageBox.Show("Are you sure you want to change this?", "Question", MessageBoxButtons.YesNo) != DialogResult.Yes);
   }
}

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

Is there any way to specify the RTF version used by the RtfFormatProvider when exporting from the RichTextEditor?

We have an application that integrates with a 3rd party system which pulls an RTF string from their RichTextBox, loads into a Telerik RichTextEditor, allows editing and then pushes it back to the control. 

It pulls into the Telerik RichTextEditor correctly, but does not render correctly when loaded back into the original control, displaying all the RTF syntax and metadata. 
I checked the string that gets pulled from each and noticed that RTF version on the original control was older version than used by the RichTextEditor/RtfFormatProvider. If there is a way to specify an older version in the RichTextEditor/RtfFormatProvider when exporting I feel this would fix the problem.

FYI: I have tested the exact same scenario replacing the RichTextEditor/RtfFormatProvider with a standard .Net RichTextBox and that works correctly.
