I have below structure in my asp.net application.
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<div id="overlay"></div>
<asp:Panel ID="pnlMain" runat="server" Visible="true">
<asp:UpdatePanel ID="upProfile" runat="server" UpdateMode="Always">
<ContentTemplate>
<div>
<table>
</table>
</div>
</ContentTemplate>
</asp:UpdatePanel>
<asp:UpdatePanel ID="upAttachment" runat="server" UpdateMode="Always">
<ContentTemplate>
</ContentTemplate>
</asp:UpdatePanel>
</asp:Panel>
<asp:Panel ID="pnlSuccessMessage" runat="server" >
<asp:Label ID="lblSuccessMessage" runat="server"></asp:Label>
</asp:Panel>
I have different textfields and dropdowns in the table of upProfile updatepanel and file upload control in upAttachment updatepanel. Now when I select one radio from the same update panel, I am getting below error and the upAttachment does not show up on page.
Uncaught Error: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'MainContent_upAttachment'. If it is being updated dynamically then it must be inside another UpdatePanel.
I have searched a lot and tried below different things, but still it is not working
1. Set the upAttachment UpdateMode to Conditional.
- In this case, it does not throw error, but the file upload control which is inside that updatepanel, it does not show up
2. Place the upAttachment updatepanel inside another updatepanel, but that too is not working.
I don't know what to do in this case. Can anyone help me on this?
Currently have a dropdownlist located inside of an Updatepanel. I have an event handler setup for the selection change event. PartialPageRendering is set to true in the script manager. The first time I select an item in the dropdownlist the whole page is reloaded. After that it only triggers the event like it should. I am capturing the PagePostBack event in the code, but the first time the index changes, this does not get set, after that it works as expected. Any ideas? Thanks!
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true"></asp:ScriptManager>
<div>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="conditional">
<ContentTemplate>
<div style="text-align:center">
<asp:DropDownList ID="DropDown1" runat="server" AutoPostBack="True" OnSelectedIndexChanged ="DropDown1_SelectedIndexChanged" Font-Size = "48">
</asp:DropDownList>
<br />
</div>
</ContentTemplate>

I have 2 updatepanels in a webforms page with 2 nested Repeater controls. In the second (inner Repeater control) I have a LinkButton to do some events and calling the click event through the OnItemCommand method of the second Repeater.
This is my Example Asp.Net page
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("Title") %>'></asp:Label>
<asp:Repeater ID="Repeater2" runat="server" OnItemCommand="Repeater2_ItemCommand">
<ItemTemplate>
<asp:Label ID="lblInsertedDate" class="text-muted" runat="server" Text=' <%# string.Format("{0: hh:mm tt}", Eval("Date")) %>'></asp:Label>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:LinkButton ID="lnkFollow" runat="server" Text="Follow" CommandArgument='<%# Eval("BrokerId") %>' CommandName="Follow"></asp:LinkButton>
</ContentTemplate>
</asp:UpdatePanel>
</ItemTemplate>
</asp:Repeater>
</ItemTemplate>
</asp:Repeater>
</ContentTemplate>
</asp:UpdatePanel>
When I click on the LinkButton, I can see the contents of the outer Repeater also gets XHRed when I inspect through browser's network Tab.
I don't want to update the contents of outer updatepanel when I click on the linkbutton inside. I want to change only text of the linkbutton with some server side function, so that the content download will be gets reduced.

I tried to set UpdateMode="Conditional" and ClientAsTriggers as false to both the inner and outer updatepanels. However it's not working. Using .net version 4.51. Any workaround for this?
I have an aspx page in which I have Ajax UpdatePanel which has a AJAX Tabcontainer which has 5 tab. In First tab I have a DropDownList for ProductID. In the second tab I have used a UserControl whose parameter needs to be reflected based on productID. I want to Access the DropDownList ProductID in the user control which I am not getting. Part of my code is
DropDownList IDList = (DropDownList)(this.Parent.FindControl("ProductID");
this is not working and I am getting NULL. I also have Tried
DropDownList IDList = (DropDownList)(this.Page.FindControl("ProductID");
Please tell me how I can do this.
As asked Part of necessary code is
<asp:UpdatePanel ID="UpdatePanelTankFormula" runat="server">
<ContentTemplate>
<asp:tabcontainer id="TabContainerTankFormula" AutoPostBack="true" runat="server" OnClientActiveTabChanged="clientActiveTabChanged" activetabindex="0" style="width:100%;">
<asp:TabPanel ID="InputDataTab" runat="server" HeaderText="Data Input">
<ContentTemplate>
<asp:DropDownList id="TankNameCombo" DataTextField="TankName" runat="server" AutoPostBack="true" DataValueField="customertankid" width="200px" onclick="javascript:SetHiddenField();"> </asp:DropDownList>
</ContentTemplate>
</asp:TabPanel>
<asp:TabPanel ID="LacticAcidAdditionTab" runat="server" HeaderText="Lactic Acid Addition">
<ContentTemplate>
//My user control
<UC:TankNote runat="server" ID="LaticTankNotesUC" GetNoteType="LAC" MEQMode="False"></UC:TankNote>
</ContentTemplate>
</asp:TabPanel>
</asp:tabcontainer>
<ContentTemplate>
</asp:UpdatePanel>
Now in the Code Behind of this User Control I want to access this DropDownList, which I am not getting. For the fix I have define a Public function that return the value of this list. But its a fix not solution.
You will have something like this in tab control.
<cc1:TabContainer ID="TabContainer1" runat="server">
<cc1:TabPanel ID="TabPanel1" runat="server">
<ContentTemplate>
<asp:DropDownList id="dropdownlist1" runat="Server"/>
</ContentTemplate>
</cc1:TabPanel>
So first you need to find tabPanel1 then find dropdownlist1 like following.
TabContainer TabContainer1= (TabContainer)(this.Page.FindControl("TabContainer1");
if (TabContainer1!=null){
TabPanel TabPanel1= (TabPanel)(this.TabContainer1.FindControl("TabPanel1");
if(TabPanel1 !=null){
DropDownList dropdownlist1= (DropDownList)(this.TabPanel1.FindControl("dropdownlist1");
}}
I have an UpdatePanel in a Repeater.
There are a few CheckBoxes in the UpdatePanel with AutoPostBack="true"
There is a Label in the UpdatePanel. I set the Text value of the label in RepeaterName_ItemDataBound as it runs on every item generated.
<asp:Repeater ID="Repeater1" runat="server" DataSourceID="XmlDataSource" OnItemDataBound="R1_ItemDataBound">
<ItemTemplate>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<div>
<asp:Label ID="DateTimeLabel2" runat="server" Text="Label"></asp:Label>
<asp:Panel ID="panID" CssClass="actionicon_normal actionicon_compare" runat="server">
<%#XPath("ID")%>
<asp:CheckBox ID="chkID" runat="server" AutoPostBack="true" />
</asp:Panel>
</div>
</ContentTemplate>
</asp:UpdatePanel>
</ItemTemplate>
</asp:Repeater>
I want the CheckBoxes to automatically update the UpdatePanel as there were no repeater around, but possibly because the OnItemDataBound does not fire on every AsyncPostBack, nothing gets updated.
What is the proper way to do this?
In the onclick (JavaScript) call this function __doPostBack('idOfUpdatePanel', '');
