Hello All,

I am using the following common function code in vb.net to show a Java based confirmation window for Delete confirmation.

VB

Public Function fnConfirmation(ByVal page, ByVal message)
        fnConfirmation = ""
        Dim sb As New System.Text.StringBuilder()
        sb.Append("return confirm('")
        sb.Append(message)
        sb.Append("');")

        page.page.ClientScript.RegisterOnSubmitStatement(page.GetType(), "alert", sb.ToString())
        Return fnConfirmation

    End Function

The message pops up and the buttons are clicked. But I am not able to get the value/button information of clicking.

Please guide!

Thanks

Presumably your delete operation is tied to a button click event of some kind, in which case you would do better to assign the confirm dialog to that - eg
Button1.Attributes.Add("onclick", "return confirm('Do you really want to delete this?')")

Thanks for the reply!
You were right in presuming use of Delete button.

I have added the suggested code in click event of button. But it is not working as I believe the delete command is to be enclosed within IF command based upon result of confirm message. But then again how do I get the return value (ok/cancel)?

done!!!

I added the code in page load event and it works..

btnDelete.Attributes.Add("onclick", "return confirm('Do you really want to delete this?')")

Thanks Wombaticus

Dear Wombaticus,

The code which worked for delete button is not working for Grid. Pls suggest. following is the code i am using in page load event of page containing grid in which delete is used as command field. following is the related code:

in html grid columns:
<asp:CommandField HeaderText="Delete" ShowDeleteButton="True" ShowHeader="True" />

in vb page load:
gdBOM.Attributes.Add("onrowdeleting", "return confirm('Do you want to delete record?')")

'where gdBOM is the name of the grid

Thanks
