You are close to the solution, just getting the wrong object. It should be like this:
jQuery(function() {
var dlg = jQuery("#dialog").dialog({
draggable: true,
resizable: true,
show: 'Transfer',
hide: 'Transfer',
width: 320,
autoOpen: false,
minHeight: 10,
minwidth: 10
});
dlg.parent().appendTo(jQuery("form:first"));
});
My suggestion would be to pull all your controls inclusive this UpdatePanel out of this UpdatePanel into an UserControl. Define events in your usercontrol that are raised when the buttons are clicked or the Dropdown's selected index get changed. Handle these events in your page that holds the Placeholder(in a single UpdatePanel,conditional,without triggers). Call the Update-method of the main update panel manually if you add UserControls.
To clarify what i mean have a look at following example:
Main-page aspx:
<asp:UpdatePanel ID="Upd1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>
</ContentTemplate>
</asp:UpdatePanel>
Codebehind:
Private Property UserControlCount() As Int32
Get
If ViewState("UserControlCount") Is Nothing Then
ViewState("UserControlCount") = 1
End If
Return DirectCast(ViewState("UserControlCount"), Int32)
End Get
Set(ByVal value As Int32)
ViewState("UserControlCount") = value
End Set
End Property
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
recreateUserControls()
End Sub
Private Sub recreateUserControls()
For i As Int32 = 1 To Me.UserControlCount
Dim uc As DynamicControls = DirectCast(Me.LoadControl("DynamicControls.ascx"), DynamicControls)
uc.ID = "DynamicControls_" & i
Addhandlers(uc)
Me.PlaceHolder1.Controls.Add(uc)
Next
End Sub
Private Sub Addhandlers(ByVal uc As DynamicControls)
AddHandler uc.asyncButton1Clicked, AddressOf ucAsyncButton1Clicked
AddHandler uc.asyncButton2Clicked, AddressOf ucAsyncButton2Clicked
AddHandler uc.syncButtonClicked, AddressOf ucSyncButtonClicked
AddHandler uc.asyncDropDownSelectedIndexChanged, AddressOf ucAsyncDropDownSelectedIndexChanged
End Sub
Private Sub addUserControl()
Me.UserControlCount += 1
Dim uc As DynamicControls = DirectCast(Me.LoadControl("DynamicControls.ascx"), DynamicControls)
uc.ID = "DynamicControls_" & Me.UserControlCount
Addhandlers(uc)
Me.PlaceHolder1.Controls.Add(uc)
Upd1.Update()
End Sub
Private Sub ucAsyncButton1Clicked(ByVal sender As Object, ByVal e As EventArgs)
'only to demonstrate how to add control dynamically and update the UpdatePanel'
addUserControl()
Me.Upd1.Update()
End Sub
Private Sub ucAsyncButton2Clicked(ByVal sender As Object, ByVal e As EventArgs)
End Sub
Private Sub ucSyncButtonClicked(ByVal sender As Object, ByVal e As EventArgs)
End Sub
Private Sub ucAsyncDropDownSelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
End Sub
ascx which holds your controls:
<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="DynamicControls.ascx.vb" Inherits="AJAXEnabledWebApplication1.DynamicControls" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>
<asp:UpdatePanel ID="myUpdatePanel" runat="server" UpdateMode="Conditional"
ChildrenAsTriggers="false">
<ContentTemplate>
<asp:TextBox ID="textBox1" runat="server" />
<asp:TextBox ID="textBox2" runat="server" />
<asp:Button ID="asyncButton1" runat="server" Text="Button1" />
<asp:DropDownList ID="asyncDropDown" runat="server" AutoPostBack="true" />
<asp:Button ID="asyncButton2" runat="server" Text="Button2" />
<asp:Button ID="syncButton" runat="server" Text="SyncButton" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="asyncButton1" EventName="Click" />
<asp:AsyncPostBackTrigger ControlID="asyncButton2" EventName="Click" />
<asp:AsyncPostBackTrigger ControlID="asyncDropDown" EventName="SelectedIndexChanged" />
<asp:PostBackTrigger ControlID="syncButton" />
</Triggers>
</asp:UpdatePanel>
Codebehind of UserControl:
Public Partial Class DynamicControls
Inherits System.Web.UI.UserControl
Public Event asyncButton1Clicked(ByVal sender As Object, ByVal e As System.EventArgs)
Public Event asyncButton2Clicked(ByVal sender As Object, ByVal e As System.EventArgs)
Public Event syncButtonClicked(ByVal sender As Object, ByVal e As System.EventArgs)
Public Event asyncDropDownSelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
Private Sub asyncButton1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles asyncButton1.Click
RaiseEvent asyncButton1Clicked(sender, e)
End Sub
Private Sub asyncButton2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles asyncButton2.Click
RaiseEvent asyncButton2Clicked(sender, e)
End Sub
Private Sub syncButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles syncButton.Click
RaiseEvent syncButtonClicked(sender, e)
End Sub
Private Sub asyncDropDown_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles asyncDropDown.SelectedIndexChanged
RaiseEvent asyncDropDownSelectedIndexChanged(sender, e)
End Sub
End Class
On this way you won't have problems with ClientID's.
Addition:
If you need access to the controls of your UserControls in the event-handlers, use one of following two options:
- cast the sender's NamingContainer to the userControl's type:
Dim uc As DynamicControls = DirectCast(DirectCast(sender, Control).NamingContainer, DynamicControls)
replace all occurences of (ByVal sender As Object, ByVal e As System.EventArgs)
with (uc as DynamicControls)
. On this way the reference of your UserControl is added to the event as parameter and you could access public properties of it from the page, f.e.:
dim txt1 as String = uc.Text1
If you have exposed a property Text1 in the UserControl:
Public Property Text1() As String
Get
Return textBox1.Text
End Get
Set(ByVal value As String)
textBox1.Text = value
End Set
End Property
The second option is the cleanest and most readable way.
Update:
According to your comment: you should place the UpdateProgress in the UserControl inside of the UpdatePanel that gets updated. Remember to set the AssociatedUpdatePanelID correctly. For example:
<asp:UpdatePanel ID="UdpForm" runat="server" UpdateMode="conditional" ChildrenAsTriggers="false" >
<ContentTemplate>
<asp:panel ID="FormPanel" runat="server">
<asp:UpdateProgress ID="UpdateProgress1" DynamicLayout="true" runat="server" AssociatedUpdatePanelID="UdpForm" DisplayAfter="0" >
<ProgressTemplate>
<div class="progress">
<asp:Image ID="ImgProgress1" runat="server" ImageUrl="~/images/ajax-loader-arrows.gif" ToolTip="loading..." /> please wait...
</div>
</ProgressTemplate>
</asp:UpdateProgress>
<asp:FormView ID="FormView1" runat="server" DefaultMode="ReadOnly" >
<ItemTemplate></ItemTemplate>
<EditItemTemplate></EditItemTemplate>
<InsertItemTemplate></InsertItemTemplate>
<EmptyDataTemplate>
</EmptyDataTemplate>
<PagerTemplate >
</PagerTemplate>
</asp:FormView>
</asp:panel>
</contenttemplate>
</asp:UpdatePanel>
<asp:UpdatePanel ID="UpdContent" runat="server" UpdateMode="conditional" ChildrenAsTriggers="false" >
<ContentTemplate>
<asp:Panel ID="PnlMain" runat="server">
<asp:UpdateProgress ID="UpdateProgress2" DynamicLayout="true" runat="server" AssociatedUpdatePanelID="UpdContent" DisplayAfter="0" >
<ProgressTemplate>
<div class="progress">
<asp:Image ID="ImgProgress1" runat="server" ImageUrl="~/images/ajax-loader-arrows.gif" ToolTip="loading..." /> please wait...
</div>
</ProgressTemplate>
</asp:UpdateProgress>
Content
</asp:Panel>
</ContentTemplate>
<Triggers ></Triggers>
</asp:UpdatePanel>
