Hi All,

I have a button:
<asp:Button id="CmdDeleteArticle"
Text="Delete Entire Article"
CommandArgument="CmdDeleteArticle"
OnClick="CMDButtonClick"
visible='<%# CheckDelete()%>'
runat="server"/>
and I use the following Sub for the onclick: (I stripped non-relavent code)

Sub CMDButtonClick(sender As Object, e As EventArgs)
Dim arg As String = CType(sender, Button).CommandArgument
Select Case arg
Case "CmdDeleteArticle"
DeleteArticle()
Case Else
'Do Nothing
End Select
End Sub

Since I am already using 'OnClick', how do I add a confirmation box? I know
I can use a regular html button with JScript and then check for button
pushed with:

If Len(Request.Form("cmdFilter")) > 0 Then
DeleteArticle()
End If

In my page load, but I would rather stick with using the
OnClick="CMDButtonClick"

I have programtically done this before, but never on a button ALREADY
containing an Onclick...

Any help would be appreciated.

Thanks
Rel

you could use the button HTMLControl as an alternative. eg:
<input type="button" id="CmdDeleteArticle" value="Delete Entire Article"
runat="server" onClick="javascript:doConfirm();"
onServerClick="CMDButtonClick"/>

What happens here is this: the onClick event is set to a javascript function
that pops up your confirm box, and since the runat="server" attribute is
present, the onServerClick event will fire on postback. Of course, the
javascript will execute before postback.

Thanks, but one small question...

This is what I came up with...

<asp:Button id="CmdDeleteArticle"
Text="Delete Entire Article"
CommandArgument="CmdDeleteArticle"
OnCommand="CommandBtn_Click"
CausesValidation="False"
visible='<%# CheckDelete()%>'
runat="server"/><br>

I had to put in the JScript progromatically, because it would error when I
just put it in with the button, complaining about the word, "Javascript" so
I did it this way..

Sub Page_Load()
CmdDeleteArticle.Attributes.Add("onclick","return confirm('Are you Sure
you want to delete this?');")

When ever I used OnServerClick="CMDButtonClick", The JScript Confirm worked
fine and postedback whenever they user clicks 'OK' but the CMDButtonClick
Sub was never getting kicked off...

I got around it by finding the
OnCommand="CommandBtn_Click"
but I am still curious to find out why the 'OnServerClick' never kicked off
my code? The way I had MY code was just replace OnCommand with
OnServerClick...

Any ideas?
No Hurry now that I have a work around
Thanks ALOT for the help
Rel
