Is it possible to add a System.Web.UI.UserControl in an asp:PlaceHolder
-
I want to create a MessageBox, that I want to use on many of my web pages. The MessageBox is a System.Web.UI.UserControl and is an .ascx file. It contains a table with som labels in it. Now on my UserEdit.aspx site I've added an asp:PlaceHolder with ID="plhMessage". At the code behind I want to add a messagebox, something like:
plhMessage.Visible = true; MyMessageBox mb = new MyMessageBox(); mb.Type = global::My.Web.Controls.MyMessageBox.EnumMessageType.Ok; mb.MessageText = "Data was saved."; plhMessage.Controls.Add(mb);Now at the commandplhMessage.Controls.Add(mb);it goes in to theprotected void Page_Load(object sender, EventArgs e)of the MyMessageBox control. But when I look at any of the Label properies it is NULL. The result is of course that there is no message to view. What am I doing wrong? Or is there a better way of doing this in VisualStudio 2005? (maybe somthing like an asp:Content, asp:ContentPlaceHolder witch I'm using on my masterpage) I've easely done this with controls of type "WebControl", but then I've had to create all the items with codelines, and I want the flexability an System.Web.UI.UserControl gives with reference to design layout. Thank you. Thomas -

Thank you. ThomasYou can always use javascript it is a little easier. (.net 2.0)
private void ShowDialog(string p_msg)
{
Type cstype = this.GetType();
StringBuilder tmpSB = new StringBuilder();
tmpSB.Append("");tmpSB.Append("alert('" + p_msg + "')");
tmpSB.Append("");
ClientScript.RegisterClientScriptBlock(cstype, "Save", tmpSB.ToString());

Thank you. ThomasYou can't use MessageBox in ASP.NET applications. You'll have to resort to javascript
alertorconfirmor create your own popup.Cheers, Mircea "Pay people peanuts and you get monkeys" - David Ogilvy
