After a button click, nothing gets posted back to the form. The Page_PreRender is firing ... I am tracing it through line by line. But lbl_ErrMsg3 never changes. (I also tried it with a textbox and it doesn't change the Text either.) Does anyone know what is wrong? Thanks HTML in ascx page ---------------------- <asp:Label ID="lbl_ErrMsg3" runat="server" Text="test3"></asp:Label> vb in the ascx.vb page ---------------------- Protected Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender Me.lbl_ErrMsg3.Text = "test this" Me.lbl_ErrMsg3.Visible = True End Sub
Tried to repro and it works fine here (this is a user control hosted in a page ?). I'm not sure how button clicks and postback are related to this. I just see the updated label regardless of wether or not this is a postback. Looks like you perhaps have multiple problems. It would be best to take them one after the other... For the label issue, don't you reload the usercontrol dynamically from the hosting page or something ? What if you just place this user control on a newly created page without any other code and runs ? Do you see "test this" or "test3" ? -- Patrice "Gene Berger" a écrit dans le message de groupe de discussion : uldxM6O7IHA.4988@TK2MSFTNGP04.phx.gbl... > After a button click, nothing gets posted back to the form.
