UserControls not working on custom dynamic pages.

Question

User-1759624489 posted

 

 hi.

1. I created a very single user control to show error messages,

 

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="ServerErrorMessage.ascx.cs" Inherits="UserControls_ServerErrorMessage" %>

<table bgcolor="#FFFF66" border="1"  width="50%">
    <tr>
        <td style="text-align: center">
            <asp:Label ID="lblError" runat="server"></asp:Label>
        </td>
    </tr>
</table>

public partial class UserControls_ServerErrorMessage : System.Web.UI.UserControl
{
    protected void Page_Load(object sender, EventArgs e)
    {
        lblError.Text = (string)ViewState["errorMessage"];
    }


    private string _errorMessage;

    public string ErrorMessage
    {
        get { return _errorMessage; }
        set
        {
            lblError.Text = value;
            _errorMessage = vale;
        }
    }

   

}

 

2. I droped the usercontrol in a CUSTOM DYNAMIC page and added the following code.

 

    protected void OnGridViewRowDeleted(object sender, GridViewDeletedEventArgs e)
    {
        if (e.Exception != null)
        {
            ServerErrorMessage1.ErrorMessage = e.Exception.Message;
            ServerErrorMessage1.Visible = true;
        }
        DetailsView1.DataBind();
    }

 

The user control never shows up; i have no Idea, I am lost.  I already debugged and the ErrorMessage property is set. so?'

 

Please help!!!

Is this a question related to the new Dynamic Data feature in .NET 3.5 SP1? It doesn't appear to be, you probably should send this in the general control forum. I think your problem is that you should be setting the label text in Page_PreRender instead of Page_Load. Your setting it to early.

 Is this a question related to the new Dynamic Data feature in .NET 3.5 SP1? Not exactly, but it works on other webpages, it doesnt work on dynamic web pages.

 

Maybe its a stupid thing but I havent been able to solve it.

 

I tried this>

  protected void OnGridViewRowDeleted(object sender, GridViewDeletedEventArgs e)
        {
            if (e.Exception != null)
            {
                ServerErrorMessage1.Visible = true;
                ServerErrorMessage1.ErrorMessage = e.Exception.Message;
            }
            DetailsView1.DataBind();
        }

 

    <uc1:ServerErrorMessage ID="ServerErrorMessage1" runat="server" />
                 

 

And nothing comes up, why_? it makes no sense!!!

Did you try setting the label in Page_PreRender instead of Page_Load like my previous message asked?

 Yes. on the page pre render of the USER CONTROL.

 

public partial class UserControls_ServerErrorMessage : System.Web.UI.UserControl
{
    protected void Page_Load(object sender, EventArgs e)
    {
       
    }

    protected override void OnPreRender(EventArgs e)
    {
        lblError.Text = (string)ViewState["errorMessage"];
        base.OnPreRender(e);

    }

    private string _errorMessage=default(string);

    public string ErrorMessage
    {
        get { return _errorMessage; }
        set
        {
            ViewState["errorMessage"] = value;
        }
    }

   

}
