Help with ASP.NET Datagrid

[Fortra]

I'm having trouble with the UpdateCommand event with the
DataGrid control. The event is wired up in the
InitializeCompo nents properly,

this.sitesDataG rid.UpdateComma nd +=
new System.Web.UI.W ebControls.Data GridCommandEven tHandler
(this.sitesData Grid_UpdateComm and);

but when the "Update" button is clicked, the eventhandler
is never fired. The "Edit" command fires its
eventhandler, but "Update" and "Cancel" do not.

One peculiar thing I have noticed is that the ItemCommand
event fires for both the Edit and Update button. However,
for both, the CommandName (e.CommandName) is always "Edit".

What am I doing wrong???

Thanks in advance!!

Hi Fortra,

Here is the code I'm using for this.

I''m using asp:TemplateCol umn to define my columns.

This is how I declare the grid in the ASP.NET page:
<asp:datagrid id=recordgrid runat="server" ShowHeader="fal se"
OnPageIndexChan ged="Grid_Chang e" PagerStyle-Visible="False"
GridLines=Horiz ontal BorderStyle="no ne" BackColor="whit e"
autoGenerateCol umns="False" DataSource="<%# GetDataGridSour ce()%>"
showfooter="Fal se" visible="true" OnEditCommand=" RecordEditComma nd"
OnDeleteCommand ="RecordDeleteC ommand" Width="100%" CellPadding="0" >

As you can see I declare the OnEditCommand, OnDelete directly in the page,
this avoid using InitializeCompo nents for this and is a cleaner solution
IMO.

The "Action" column is declared as:

<asp:templateco lumn ItemStyle-VerticalAlign=" Top" ItemStyle-Width="25"
ItemStyle-HorizontalAlign ="Center" >
<itemtemplate >
<asp:imagebutto n ToolTip="Edit Record" runat="server"
Visible="true" CommandName="Ed it" ImageUrl="image s/ico_edit.gif"
ID="Imagebutton 2" />
</itemtemplate>
</asp:templatecol umn>

As you see I'm using the CommandName property of the button, this indicate
what is the event to be risen on the datagrid.

As I said this come from a working page so you should have no problem using
it.

Hope this help,

Thanks again!

I did find my problem in the code-behind class - in the
InitializeCompo nents() method, I was calling the datagrid's
DataBind() method, event though I defined a BindData()
method to handle this that was called in the Page_Load()
method based on the IsPostBack property. As soon as I
removed this extra call, all of my datagrid events wired
up properly.

Hi,

Yes, of course I use it, it's there where the RecordEditComma nd method is
declared , what I declare in the aspx code is which method in the code
behind will handle the event. I think this easier that use hook the event in
the InitializeCompo nents method.

Hope this help,

So you do not use a code-behind file for the UpdateCommand
event handler? You embed it directly on the page?
