Hello,

We noticed the following problem with the RadGridView:

When you have Excel like filtering enabled, and you click on the filtering icon for a column that has duplicate decimal numbers, the app crashes with a message like this:

"Item has already been added. Key in dictionary: '26.7' Key being added: '26.7'"

Please find attached screenshots with grid of data and error message.

Configuration used:

Rad Controls for Win Forms 2010 Q3; WinXP, .NET 2.0, VB.NET

Here is the code that populates a test grid with data:

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Dim rand As Random = New Random()

Dim dt As DataTable = New DataTable()

dt.Columns.Add("Pecentage", GetType(Double))

dt.Columns.Add("Price", GetType(Double))

For i As Integer = 1 To 10000

dt.Rows.Add(rand.Next(0, 100) + rand.Next(0, 100) * 0.1, rand.Next(0, 1000000))

Next

grdData.DataSource = dt

grdData.BestFitColumns()

End Sub

Thanks.
