javascript confirmation message for deleting an item from datalist

Question

I have a photogallery menu. Inside it I have kept many albums. Inside each album, there are many photos. When I click on the album it is redirected to the photo page. I have followed the orkut site. For each album and each photo I have kept edit and delete buttons.

 

My question is, when I am deleting it should show a message box asking "Are you sure you want to delete? "

 

In both the cases (in case of albums page as well as incase of photos page) I have taken a datalist. In its itemtemplate I have taken the link buttons for edit and delete.

 

 

For deleting I have written the following code in its code behind.

 

Sub Delete_Command(ByVal sender As Object, ByVal e As DataListCommandEventArgs)

Dim id As String

id = dlAlbum.DataKeys(e.Item.ItemIndex)

con = New SqlConnection(conn)

Dim str As String = "Delete from Album_Images where ID=" & id

com = New SqlCommand(str, con)

Try

con.Open()

com.ExecuteNonQuery()

Response.Write(strDeleteMessage)

Catch e1 As Exception

Response.Write("<Script>alert('" & e1.Message() & "');</Script>")

End Try

'for binding the data in grid after deletion

ShowGrid()

End Sub

 

Then in its html page I have called the delete function like below:

 

<asp:LinkButton id="delete" Text="Delete" CommandName="Delete" Runat="server"></asp:LinkButton>

 

 

You please tell me how that alert message
