I feel your pain :)
Here is the way I do it
1. Drop somewhere on a page a LinkButton (let say with id = LinkButton1),
wire up Click event to LinkButton1_OnClick
2. Make a Text property empty... We do not want to see that LinkButton. It's
a decoy to generate Click event
3. In every row of your datagrid instead of button have it like this
<input type="button" OnClick="__doPostBack('LinkButton1','<%#Eval("ID") %>')"
>
NOTE: not a server control. Just plain html. you can have a link if you want
to..
like <a
href="javascript
:__doPostBack('LinkButton1','<%#Ev al("ID")%>')">Click Me
</a>
4. in LinkButton1_OnClick get the row ID by reading __EVENTARGUMENT
int iRowId = Int32.Parse(Request.Form["__EVENTARGUMENT"]);
PS: code is simplified to make it clear.
In reality you will need to use LinkButton1.ClientID instead of hardcoded
value 'LinkButton1'
So <a href="javascript
:__doPostBack('LinkButton1','<%#Ev al("ID")%>')">Click
Me </a>
will be
<a
href="javascript
:__doPostBack('<%=LinkButton1.Clie ntID%>','<%#Eval("ID")%>')">Click
Me </a>
Good luck.

>I have a datagrid which I am adding BoundColumns to it programatically.
Tehre are already 5 columns defined in the aspx as template columns, two
link
buttons and two image buttons. The datagrid should dsiplay the two link
buttons, then the dynamically generated bound columns, then the 3 image
buttons. The problem is when I insert the BoundColumns into the grid
using
the DataGrid.AddAt function I lose the databinding on the CommandArgument
of
the image buttons when capturing the OnCommand event. The explictly
instantiated command however does keep its value.
The sender and CommandEventArgs are almost useless to me at this point, it
is supopsed to contain the ID of the row of data it represents. If I
could
get the number iof the row in terms of the datagrid I could work around it
by
using the DataKeys collection. DO I need to do something special in the
databinding or viewstate? One way or another I need to figure out which
row
I clicked on, either in context of the data grid itself or the ID of the
row
of data.
