Cancelling linkButton in GridView from javascript

[David Davis]

I have a GridView with a ButtonField column set as ButtonType = Link. I want
to add a client-side script call that would cancel the GridView1_RowCommand
event.

I add the client-side script using the OnClientClick property as follows:

If e.Row.RowType = DataControlRowType.DataRow Then
Dim lnkbtnListBill As LinkButton = _
CType(e.Row.Cells(4).Controls(0), LinkButton)
lnkbtnListBill.OnClientClick =
"javascript:ClearTrackerDialog();"
End If

The resulting html source has the postback in a separate href as follows:

<a onclick="javascript:ClearTrackerDialog();"
href="javascript:__doPostBack('grdResults','ListBillLink$0')">C9101234</a>

I need to somehow combine these so my ClearTrackerDialog() comes in the href
just before the post back script so if it returns false, the post back will
not occur.

Thanks, --David

Ok, just figured it out. I need to add a "return" statement on my javascript
call:

lnkbtnListBill.OnClientClick = "return ClearTrackerDialog();"
