I would on like AJAX on one content page and want to add an UpdatePanel to the MasterPage and wrap a UserControl that is being loaded from the MasterPage in that UpdatePanel all from the ContentPage. Is it possbile to do this? I have some code but it is not working.
protected override void OnPreInit( EventArgs e ) { ScriptManager sm =new ScriptManager(); sm.ID ="ScriptManager1"; Master.Controls.Add( sm ); UpdatePanel panel =new UpdatePanel(); panel.ID ="upMaster"; panel.ContentTemplateContainer.Controls.Add(this.Controls[0] ); AsyncPostBackTrigger trig =new AsyncPostBackTrigger(); trig.ControlID ="btnDelete"; trig.EventName ="Click"; panel.Triggers.Add( trig ); Master.Controls.Add( panel );base.OnPreInit( e ); }I changed my code and now can get the page to load but now I dont see my usercontrol on the masterpage
protected override void OnPreInit( EventArgs e ) { UpdatePanel panel =new UpdatePanel(); panel.ID ="upMaster"; UserControl uc = (( UserControl )Master.FindControl("CartSummary1" )); panel.ContentTemplateContainer.Controls.Add( uc ); panel. //AsyncPostBackTrigger trig =new AsyncPostBackTrigger();//trig.ControlID = "btnDelete"; //trig.EventName = "Click"; //panel.Triggers.Add( trig ); HtmlForm form1 = ( HtmlForm )Master.FindControl("Form1" ); form1.Controls.Add( panel );//Master.Controls.Add( panel );base.OnPreInit( e ); }Yes,It is possible.
Do it like this:
MasterPage.master:
<%@. Master Language="C#" %>
<%@. Register src="http://pics.10026.com/?src=UserControlA.ascx" TagName="UserControlA" TagPrefix="uc1" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<body>
<form id="form1" runat="server">
<div>
<uc1:UserControlA ID="uc1" runat="server" />
<asp:contentplaceholder id="ContentPlaceHolder1" runat="server">

</div>
</form>
</body>
</html>Default.aspx:
<%@. Page Language="C#" MasterPageFile="~/MasterPage.master" Title="Untitled Page" %>
<script runat="server">
protected void Button1_Click(object sender, EventArgs e)
{
TextBox1.Text = DateTime.Now.ToString();
}
protected void Page_PreInit(object sender, EventArgs e)
{
HtmlForm form1 = (HtmlForm)Master.FindControl("form1");
ScriptManager sm = new ScriptManager();
sm.ID = "ScriptManager1";
form1.Controls.AddAt(0, sm);
UpdatePanel panel = new UpdatePanel();
panel.ID = "upMaster";
UserControl uc = ((UserControl)Master.FindControl("uc1"));
panel.ContentTemplateContainer.Controls.Add(uc);
form1.Controls.Add(panel);
}</script>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<div style="display:none;"><asp:Button ID="Button2" runat="server" Text="Button" OnClick="Button1_Click" /></div>
</ContentTemplate>
</asp:UpdatePanel>
</asp:Content><asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder2" Runat="Server">
<script type="text/javascript" language="javascript">
function doclick(){
$get('<%= Button2.ClientID%>').click();
}
</script>
<asp:Button ID="Button1" runat="server" Text="Button" UseSubmitBehavior="false" OnClientClick="doclick();return false;" />
</asp:Content>UserControlA.ascx:
<%@. Control Language="C#" ClassName="UserControlA" %>
<asp:TextBox ID="TextBox1" runat="server">TextBox in UserControlA</asp:TextBox>
