 Hi there.

I have a page with a menu. an and then the content.
My thing is. That i have the update panel, and inside that i have a regual panel in which i add the Web User Controls i need. Which all works fine. My problem is. That i i have a submit funcion on almoast all the Web User controls. What i would like is that i inside that update panel, can dispose the original Web user Control and then add a response Web User Control.

In normal language. Is there a way that i can load one web user control into antoher and then disposose the original?

well, what you can do is get a reference to the placeholder where your user control is being loaded. then you can remove your 1st user control and add the new one.

not suer if this is your scenario, but it should point you in the right direction (as allways, there are other ways of doing this):


<%@ Control Language="C#" ClassName="user1" %>
<%@ Reference VirtualPath="user2.ascx" %>

<script runat="server">
    void handle(object sender, EventArgs args)
        Page page = this.Page;
        Control ctl = page.FindControl("holder");
<span>user control 1</span>
<asp:Button runat="server" ID="bt" Text="Change to 2" OnClick="handle" />


<%@ Control Language="C#" ClassName="user2" %>

<script runat="server">

<span>Control 2</span>


<%@ Page Language="C#" %>
<%@ Register Src="~/user1.ascx" TagName="user" TagPrefix="pr" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">


<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled Page</title>
    <form id="form1" runat="server">
        <atlas:ScriptManager runat="server" ID="manager" EnablePartialRendering="true" />
        <atlas:UpdatePanel runat="server" id="panel">
                <asp:Panel runat="server" ID="holder">
                    <pr:user runat="server" id="usr" />

 I have a similar kind of issue. My user control has a dropdownlist and list box based on the property DisplayControl set , either dropdown list or list box will be displayed in the calling page.

I am placing this user control inside a gridview - Edit item template and Gridview is placed inside an updatePanel. This way control is working fine, but the update becomes really slow (around 5min).

Any suggestion to solve is appreciated.

 Thanks and Regards

I have a web user control being used by another web user control, but the one being used will not display the labels in the resx file.
I am using DotNetNuke version 3.13 (might be 3.013) on a Window's XP machine, SP2. I have what I find to be an extremely odd situation. I have a project called TDS.Controls. This project is a web control library. Each control has its own resx file, which is located in the App_LocalResources directory. Each control inherits from Framework.UserControlBase, just like DotNetNuke's User control in DNN\Controls\User.ascx.vb. As a matter of fact, this control is doing the exact same thing I am trying to do. It is a web user control with its own resx file being used by another web user control (See ...

Single page with multiple user web controls VS Multiple page with specific user web controls
I have a question regarding single page with multiple user web controls vs multiple page with specific user web controls   Option 1: I am of the opinion to have multiple pages with specific user web controls and use an object to store all the information as the user navigates through the application. And finally at the end, read this object and save all the information to the backend database.   Option 2: My respected team member suggests that we have only one page, with all the specific user web controls and not use an object, instead show/hide the user web controls based ...

UpdatePanel within a web user control resets data of controls outside the user control

It makes use of an UpdatePanel (within the user control) to refresh the marquee text (within the updatepanel) at periodic intervals. For this I added a timer control and its tick event as an async postback trigger for the UpdatePanel. I have a lot of textboxes and dropdown list boxes (all with runat=server) on the page outside the above user control. These are also contained in different UpdatePanels. Problem is, when the user control does a postback to refresh the marquee text, it causes some of...
