Datagrid won't sort

I have a datagrid that won't sort. The event handler is firing and return
label text, just not the sort.

Here's my Sub Page_Load and Sub DataGrid1_SortCommand:

--------------------

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here
SqlDataAdapter1.Fill(DsAdvanced1)

If Not IsPostBack Then
DataGrid1.DataBind()
Provinces.DataBind()
Districts.DataBind()
SubDistricts.DataBind()
Communities.DataBind()
End If

End Sub

--------------------


Public Sub DataGrid1_SortCommand(ByVal source As Object, ByVal e As
System.Web.UI.WebControls.DataGridSortCommandEvent Args) Handles
DataGrid1.SortCommand

lblWhatClicked.Text = "You clicked: " & e.SortExpression

Dim dv As New DataView(DsAdvanced1.Tables(0))
dv.Sort = e.SortExpression
DataGrid1.DataSource = dv
DataGrid1.DataBind()

End Sub

Try changing the followin
dv.Sort = e.SortExpressio

t
dv.Sort = e.SortExpression & " ASC

The way you are doing sort will only handle one way sort (i.e. all columns can only be sorted in ascending order). If you want to be able to sort a column both ascending and descending order you'll need to do some more work

The following is a good article on customizing the DataGrid control. There is a section on how you can implement 2 way sorting (search for What about Sorting? in the article)

Suresh...thank you for assisting. I added the & " ASC" as you suggested.
Unfortunately, that did not change anything...the datagrid still not
sorting...it is posting and running the Sub as evidenced by my
lblWhatClicked.Text = "You clicked: " & e.SortExpression, but the table is
still un-sorted.

Could you take another look?

Public Sub DataGrid1_SortCommand(ByVal source As Object, ByVal e As
System.Web.UI.WebControls.DataGridSortCommandEvent Args) Handles
DataGrid1.SortCommand

lblWhatClicked.Text = "You clicked: " & e.SortExpression

Dim dv As New DataView(DsAdvanced1.Tables(0))
dv.Sort = e.SortExpression & " ASC"
DataGrid1.DataSource = dv
DataGrid1.DataBind()
End Sub

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load

Suresh, thanks for the follow-up...

When I tried that, I get an error on compile: "Value of type
'System.Data.DataView' cannot be converted to 'System.Data.DataTable'."

Sorry for that I made a mistake. I'm not familiar with VB.NET that much

So
Dim dv As New DataView(DsAdvanced1.Tables(0).DefaultView
shoule b
Dim dv As DataView = ds.Tables("Books").DefaultVie

Just FYI (I'm posting VB.NET code with a grid that has sort enabled and working

ASPX
------
<aspataGrid id="DataGrid1" runat="server" AllowSorting="True"></aspataGrid

VB Codebehind
-----------------

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Loa
If Not Page.IsPostBack The
Dim objConn As SqlConnection = New SqlConnection("database=pubs;server=mysqlserver;ui d=myuname;password=mypwd"
Dim objAdap As SqlDataAdapter = New SqlDataAdapter("select title_id, title, price from Titles", objConn

Dim ds As DataSet = New DataSet(
objAdap.Fill(ds, "Books"

Dim dv As DataView = ds.Tables("Books").DefaultVie

dv.Sort = "title ASC
DataGrid1.DataSource = ds.Tables("Books").DefaultVie
DataGrid1.DataBind(
End I
End Su

Private Sub DataGrid1_SortCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridSortCommandEvent Args) Handles DataGrid1.SortComman
Dim objConn As SqlConnection = New SqlConnection("database=pubs;server=mysqlserver;ui d=myuname;password=mypwd"
Dim objAdap As SqlDataAdapter = New SqlDataAdapter("select title_id, title, price from Titles", objConn

Dim ds As DataSet = New DataSet(
objAdap.Fill(ds, "Books"

Dim dv As DataView = ds.Tables("Books").DefaultVie

dv.Sort = e.SortExpression & " ASC
DataGrid1.DataSource = ds.Tables("Books").DefaultVie
DataGrid1.DataBind(
End Su

Hope this helps you narrow the problem

Suresh,

Seems like we're almost there. I realized I had a SORT BY ASC command in my
stored procedure that may have been hindering. I still unable, however, to
get either the pre-are postback code to sort in either direction. To
simplify and troubleshoot, I'm just try to sort ASC by a specified field in
the the initial load of the page, and then sort DESC by the same column in
the event of a DataGrid1_SortCommand.

No sorting is taking place at all with what I have here, though.

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here

If Not Page.IsPostBack Then
SqlDataAdapter1.Fill(DsAdvanced1)
Dim dv2 As DataView =
DsAdvanced1.Tables("sac1SelectSurvey1").DefaultVie w
dv2.Sort = " clnName ASC"
'e.SortExpression &
DataGrid1.DataSource =
DsAdvanced1.Tables("sac1SelectSurvey1").DefaultVie w
DataGrid1.DataBind()

Provinces.DataBind()
Districts.DataBind()
SubDistricts.DataBind()
Communities.DataBind()

End If

End Sub

Public Sub DataGrid1_SortCommand(ByVal source As Object, ByVal e As
System.Web.UI.WebControls.DataGridSortCommandEvent Args) Handles
DataGrid1.SortCommand

lblWhatClicked.Text = "You clicked: " & e.SortExpression

SqlDataAdapter1.Fill(DsAdvanced1)
Dim dv2 As DataView =
DsAdvanced1.Tables("sac1SelectSurvey1").DefaultVie w
dv2.Sort = " clnName DESC"
'e.SortExpression &
DataGrid1.DataSource =
DsAdvanced1.Tables("sac1SelectSurvey1").DefaultVie w
DataGrid1.DataBind()
End Sub

No this is ok. Because when you sort the DataView it's already detached from the DB and does a fresh sort on the recordset with the criteria specified by the user (i.e. clicking on the columns)

Damn, again another mistake by me. Although it does work either way in my sample
>DataGrid1.DataSource = DsAdvanced1.Tables("sac1SelectSurvey1").DefaultVie


Instead shoule b
DataGrid1.DataSource = d

Finally in the DataGrid1_SortCommand method

>Dim dv2 As DataView = DsAdvanced1.Tables("sac1SelectSurvey1").DefaultVie
>dv2.Sort = " clnName DESC
>'e.SortExpression &>DataGrid1.DataSource = DsAdvanced1.Tables("sac1SelectSurvey1").DefaultVie
>DataGrid1.DataBind(


dv2.Sort = e.SortExpression & "DESC
o
dv2.Sort = e.SortExpression & "ASC

You have the following
>dv2.Sort = " clnName DESC

This will always sort by clnName DESC everytime you click on a column header

Change it to the way I've described above and see if it'll work

Suresh,

Nope, still same thing.

Should I have a special "Imports" statement at the top of this user
control's code-behind? Currently I don't have any.

I'm using SqlDataAdapter remember. Although I'm assuming that if there was
a problem with Imports, it would not even render what data I have.
