Still looking for an answer

Hi
I have a web form with a Datagrid. Within the data grid I have a Column
button. If the button is of type "Linkbutton" my VB code-behind will catch
the users
"click"
However, if it is set to "Pushbutton" I am unable to trap the users
click. See code Below.
I don't understand what I am missing. why won't the
"Pushbutton" work?

VB code Behind:
Private Sub DataGrid1_ItemCommand(ByVal source As Object, ByVal e As
System.Web.UI.WebControls.DataGridCommandEventArgs) Handles
DataGrid1.ItemCommand
'get value of row here
End Sub

HTML:
<body MS_POSITIONING="GridLayout">
<form id="Form1" method="post" runat="server">
<asp:DataGrid id="DataGrid1" style="Z-INDEX: 101; LEFT: 80px; POSITION:
absolute; TOP: 140px" runat="server" Width="484px">
<Columns>
<asp:ButtonColumn Text="Select" ButtonType="PushButton"
CommandName="Select"></asp:ButtonColumn>
</Columns>
</asp:DataGrid>
</form>
</body>

Thanks
Brian

Notice that there is a separate group for the ASP.NET datagrid available:

Yes but I am not doing ASP this is a web form run by VB code-behind? The
event would be traped by server side VB.Net code not ASP, client side code.

ButI'll try there too.

It's ASP.NET, not VB.NET Winforms. You better get your terminology
straightened out ; )

Lucas,

I do not see what is wrong in the terminologie from Brian, as well not in
the message from Herfried by the way.

That group is special for the Webform Datagrid, in that there is not much
difference between VBNet scripting or VBNet for Dll.

The only problem is that there are almost no answers given in that newsgroup
at least the last 4 days.

Herfried was right to redirect the question to the Webforms group...
because the datagrid in ASP.NET functions very different than the winforms
datagrid. But I don't think the original poster realizes the difference...
or perhaps I misinterpreted his answer.

I didn't redirect anybody. I only provided a suggestion.

I understand the difference.
However this is the only group you can find an answer in.
I Agree that it is an ASP form but all the code I am using is VB.Net server
side code behind, not code within the HTML part of the application.
So since this is the VB.Net NG I placed my question here.
But I am not a highly educated programmer I am a self-taught retired
musician looking for a little help.
I apologize if I did or said something wrong.

Brian,

Did you load your datagrid with data?
With me did it work fine,

You can try it.
\\\
Private Sub Page_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles MyBase.Load
If Not IsPostBack Then
builddata()
DataGrid1.DataBind()
Else
builddata()
End If
End Sub
Private Sub builddata()
Dim dt As New DataTable
dt.Columns.Add("Column1")
For i As Integer = 0 To 9
Dim dr As DataRow = dt.NewRow
dr(0) = i.ToString
dt.Rows.Add(dr)
Next
DataGrid1.DataSource = dt
End Sub
Private Sub DataGrid1_ItemCommand(ByVal source As Object, _
ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) _
Handles DataGrid1.ItemCommand
DataGrid1.EditItemIndex = e.Item.ItemIndex
DataGrid1.DataBind()
End Sub
///

I hope this helps?

There is for the windowforms datagrid as well a special newsgroup

microsoft.public.dotnet.languages.vb.controls

However that datagrid is as well answered here.
And I see not any problems for both in that.

For draging a datagrid to a form there is no newsgroup needed.

The problems come when how you implement the language.vb code.

Just my thought

I found microsoft.public.dotnet.framework.aspnet to be very helpful. Lots
of traffic there (and since it's dedciated to ASP.NET, they may know the
answer).

As for your problem with the pushbutton - I never had that problem myself.
The code I used is practically identical to yours and it works fine on my
end.

Yes as a metter of fact I have working Web Application that work just fine.
Thats why I ask "what am I missing?" I started a new project, added a
datagrid, called the same web-service that another one of my projects uses.
Populated the grid with the same data, have one column with a button just
like my working application but it fails to call when the button is of type
"PushButton"
Very darn odd! I just thought i was forgetting a namespace or needed to
place a handler somewhere but I can't find anything that points to the
problem.

I will try your example and let you know !

Thanks ;-)

An idea - are you rebinding the datagrid on each load? I think if you do...
that may invalidate the pushbutton.

Cor, you example works fine. My other application works fine. I started a
new project, with a new web form-datagrid-WS call-and code. It works fine.
My best guess is there is/was somthing messed up about that project.

Lucas, Yes that could be, but i only call for the dataset on the first load
i use the "Is Post Back" to filter my events on post back.

I am going to do a little more R&D and will post to all what error i have
made here when i am sure.

Thanks you all for the HELP!
BrianDH
P.S. you might want to see why no one eve answers over on the
Framework.Datagrid NG

OK, its just this one project, I have no idea why the code fails to work so
I saved my .vb files and dumped the project. Never thought to try that.

Anyway it works now!

I thank you all!
