I have multiple Grid objects that are editable on my page. The following is
an example of the onEditCommand method. In this case D1 (the Grid object)
is known.

****************************************************
sub DataEdit(S as Object, E as DataGridCommandEventArgs)
trace.warn("in DataEdit")
D1.EditItemIndex=Cint(E.Item.ItemIndex)
FillUpGrid()
end sub
*****************************************************

In my case, I have a Datalist that has multiple DataGrids in them, something
like:

************************************************************
<asp:datalist id="DataList1"
runat="server"
Width="100%"
BorderWidth="0px"
OnItemCommand="OnSelectIndexChanged"
footerstyle-horizontalalign="center"
CellPadding="0"
CellSpacing="0"
style="margin:0">
<AlternatingItemStyle cssClass=alternateRow
</AlternatingItemStyle>
Click to expand...
<asp:DataGrid visible="False"
id="DataGrid1"
runat="server"
Width="400px"
Height="79px"
AutoGenerateColumns="False"
GridLines="None"
onEditCommand="DataEdit"
onCancelCommand="DataCancel"
onUpdateCommand="DataUpdate">
</asp:datalist>
******************************************************************************************

Here there are multiple datagrids (one for each listitem). When I run my
onEditCommand routine, it needs to know the DataGrid to bind the data to.

It can't be DataGrid1.

How do I determine the Grid object from:

sub DataEdit(S as Object, E as DataGridCommandEventArgs)

Thanks,

Tom.
 
Tom, typically you'd have a separate event handler for each of the
DataGrids' OnEditCommand events. However, you have some (or all) of the
DataGrid's trigger the same event handler. The first input parameter of
the event handler contains the control that raised the event.

sub DataEdit(S as Object, E as DataGridCommandEventArgs)
trace.warn("in DataEdit")

Dim dg as DataGrid = CType(S, DataGrid)
trace.warn("The DataGrid is " & dg.ID)

D1.EditItemIndex=Cint(E.Item.ItemIndex)
FillUpGrid()
end sub

Scott,

That was what I was looking for.

I assume that I would then do something like:

Dim dg as DataGrid = CType(S, DataGrid)

dg.bind()

I really appreciate the help,

Thanks,

Tom.
