display description in property box

Hi,

I have made an options form, where I import my settings to a propertygrid by this code:

Code:

---

PropertyGrid1.SelectedObject = My.Settings

---

but now, the box in the bottom with the tag, displays the name of the setting too, and I want it to display the description I entered in the the settings...
I tried this to change the tag of setting "Backcolor" but it didn't work...

Code:

---

    Private Sub PropertyGrid1_SelectedGridItemChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.SelectedGridItemChangedEventArgs) Handles PropertyGrid1.SelectedGridItemChanged
        Dim pdc As PropertyDescriptorCollection = TypeDescriptor.GetProperties(PropertyGrid1.SelectedObject, True)

        Dim pd As PropertyDescriptor

        For Each pd In pdc

            'Getproperty name

            Dim strPropertyName As String = pd.Name

            'MessageBox.Show(strPropertyName)

            'Getproperty value

            Dim strPropertytag As String = pd.GetValue(PropertyGrid1.SelectedGridItem.Tag).ToString

            'MessageBox.Show(strPropertyValue)

            'Changeproperty value

            If strPropertyName = "Backcolor" Then
                MsgBox("")
                PropertyGrid1.SelectedGridItem.Tag = "blablabla"
            End If
        Next
    End Sub

---

Furthermore I have some problems with organizing the settings, now they are all in "Misc' bye default, but I would like to create my own categories and put the settings in there own right category...
This problem I found by search, but it was unclear for me what to do, it didn't get resolved :(

Also, is there any possibility I can change the startposition of the line that seperates the names from the data in it?

any help is appreciated!
