Hello
I've a listview,
The datasource is a dataset builded like that:

Dim dataSet As DataSet = New DataSet
Dim dtPart As DataTable = New DataTable("Products")
dtPart.Columns.Add("id", Type.GetType("System.String"))
dtPart.Columns.Add("name", Type.GetType("System.String"))
dtPart.Columns.Add("brand", Type.GetType("System.String"))
dtPart.Columns.Add("price", Type.GetType("System.Double"))


then I ve a method to sort it by price:

Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim expression As New RadListViewSortExpression()
        listview .SortExpressions.Clear()
        expression.FieldName = "price"
        expression.SortOrder = RadListViewSortOrder.Ascending
        listview.SortExpressions.AddSortExpression(expression)
        listview .Rebind()

End Sub

My issue is it sort by price considering the column as string. For instance:

30 will be greater than 200

How can I tell the sortexpressions that it sort decimals?

Thanx

Hi,

Could you share your full page source code along with the code-behind file content? Thus we will be able to examine your code and let you know what might be causing this behavior.
