GridView.Sort problem


B

bfwd

I have the following in VS 2008. I get a stack overflow condition
raised when it tries to execute the
"GridView1.Sort(expression, direction)" statement in the
GridView1_Sorting event handler. Is there recursion going on here that
I do not see?

<asp:GridView ID="GridView1" runat="server" AllowSorting="True"
AutoGenerateDeleteButton="True"
AutoGenerateEditButton="True"
AutoGenerateSelectButton="True" BackColor="White"
BorderColor="#999999"
BorderStyle="None" BorderWidth="1px" CellPadding="3"
GridLines="Vertical"
onsorting="Gridview1_Sorting"
OnSorted="Gridview1_sorted"
onselectedindexchanged="GridView1_SelectedIndexChanged"

<HeaderStyle BackColor="#000084" Font-Bold="True"

</asp:GridView>

Protected Sub Page_Load(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Me.Load
If Not IsPostBack Then
sqlcmd = New SqlCommand("select * from
dbo.semestertable", myDB)
myDB.Open()
reader = sqlcmd.ExecuteReader
GridView1.DataSource = reader
GridView1.DataBind()
myDB.Close()
End If
End Sub

Sub GridView1_Sorting(ByVal sender As Object, ByVal e As
GridViewSortEventArgs)
Dim expression As String
Dim direction As SortDirection
expression = e.SortExpression
If e.SortDirection = SortDirection.Ascending Then
direction = SortDirection.Descending
Else
direction = SortDirection.Ascending
End If
GridView1.Sort(expression, direction)
End Sub

Sub GridView1_Sorted(ByVal sender As Object, ByVal e As
EventArgs)
message.text = "you sorted on column: " &
GridView1.SortExpression & _
" in " & GridView1.SortDirection & " order"
message.visible = True
End Sub

hi
you are not binding your gridview in sort event if i am not wrong..and
one more thing if you are binding your gridview with sqldatareader
then it doesn't support sorting..either you have to convert
sqldatareader to dataset or bind gridview with dataset..

That's it...

Right. I used a DataTable and that worked OK.
Thanks for pointing me in the right direction.
