AJAX :: Server Side Controls Not Updated?
Dec 17, 2010
I have UpdatePanel1 inside of which I have a Server Side Call Button - BT_ServerCall.
Then I have a second UpdatePanel2 which has a listbox (populated in pageload with some items) , a label, a hidden field, and a Button which calls a javascript function BT_JSCall.
Finally there is a second listbox which does not reside in an updatepanel.
i am populating the second listbox with values selected in the first listbox. then I click the BT_JSCall button which calls the javascript function copy_to_hidden_field() , inside which I take the values from the second listbox and store them as a concatenated string in the hidden field. Lastly, in the javascript function I simulate a button click event on BT_ServerCall. At this point I hit the server side method for the click event and I extract the value from the hidden field. lastly I change the value of the hidden field and also copy the new value to the label. I call the updatepanel2 update method (both updatepanels are set to updatemode conditional).
here is the problem: neither the hidden field nor the label get updated with the new text.
here is code
aspx.cs:
public partial class WebForm3 : System.Web.UI.Page

I have a hidden variable and its value is being updated using javascript(client side) which I make a call from server side code. After making the call I am not able to retrieve the updated value from Server side variable. I went through this forum [URL] but not able find a way how to implement functionality with IFRAME. I am trying to call the client side code and retrieve the updated value from server side in page_load event.

i use asp.net and c# to build my web application.i'm trying to display message dynamically using ModalPopup extender.I add the event inside a loop and the message is selected according to my logic.My issue is that the label stays empty, it seems that the set does not take effect, so the popup comes up empty.
the code:
<asp:Panel ID="pnlMsg" runat="server" CssClass="modalPopup" Style="display: none">
<asp:Label ID="lblModalMsg" runat="server" ></asp:Label>
<asp:Button ID="btnOk" runat="server" Text="OK" />
</asp:Panel>
<asp:ModalPopupExtender ID="ModalPopupExtender1" runat="server" TargetControlID="hidForModel" PopupControlID="pnlMsg"

I know that I can receive an javascript object from the server via ASP.NET AJAX using Json. But I am not sure how can I send an javascript object from my client-side javascript to my server-side code. And if I can, how can I extract this object in my server-side code and access its members?

I reordered some items in a listbox using Javascript. When I read the items in a postback in the code behind (ASP.NET), the order is in the original order. How do I get the same order as shown in the screen after Javascript manipulation?

in a form i have a buttoin, when click both OnclientClick and postback should happen. on clicking the "Email" button a client side "mailto" tag should do the work and pull a new message window on the client's machine.
whereas, the email addresses should be invoked by the post back. so , when clicking the button the server side post should happen and on return the client side script should be invokded with the values read during post back, and populate all the email addresses.
i need know how to first do a server hit take the values and then execute the client script with those values without using AJAX

I am using VS2010 and .NET4 for a web app. I have a script manager/update panel that has a couple of grids.
The client just leaves the page opens and views an updated grid every 30 seconds or so.
I want to refresh the grid by calling the server side method to load the grid, but not load the whol page using meta refresh or similar (too much screen flicker and unnecessary bandwith).
Is it possible to set some timer using javascript or something and call a specific server method to refresh controls?

I have a list of items on an ASP.net page. That list is selectable in that whenever the user clicks on one, the page does a postback and the server code stores the index or some unique identifier of the picture in a ViewState property indicating that it is currently selected.
I would like to minimize the load on the server and therefore I would like to store the index or unique identifier representing the image in some way on the client side. The best way I can think to do this is to store said information in a hidden field ), however I had two questions about this before I go crazy:
Is this a security risk in any way, shape or form (i.e., exposing implementation details of the page)?
Is there a better/best way to do this that is more industry-standard? Does ASP.net provide a framework to do this that is cleaner than my idea? Seems like this would be a fairly common requirement to me...

We have an UpdatePanel that is showing a gridview with loads of data in it. We have loads of well written sprocs that don't take very long, BUT we have a few horrible ones that take ages.
We do intend to rewrite them but in the interim we have put the ADO.NET commandtimeout up to 180s. The scriptManager.AsyncPostBackTimeout is set to 240s. We want to handle this on the serverside. One of the reports still fails (it's got a couple of nested cursors in it - someone who hasn't had SQL lesson 101 from me!).
Half the time, the nice error timeout message is shown using server side handling of the command timeout. The problem is that the other half of the time the commandtimeout doesn't seem to fire.

For my project, i have decided to use AjaxControlToolkit's ModalPopup controls. I have obtains codes from this website: [URL] After following all the steps provided by Matt, I am getting some problems when i want to save my edited information. Scenario 1: Select the first item from the gridview, modify the details at the details view and click save, gridview updates and shows the edited information and it is stored into the database.
Scenario 2: Select the second item onwards from the gridview, modify the details at the details view and click save, screen remains at detailsview and edited information is not saved, click cancel button to return to gridview, data at the gridview was not updated. So basically, the update function works only for the first item from the gridview. The following is parts of my code:
<%-- Display list of Activities according to the Project--%>
<asp:UpdatePanel ID="UP_ActList" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:GridView ID="GV_ActList" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDS_ActList" DataKeyNames="dbID"
OnSelectedIndexChanged="GV_ActList_SelectedIndexChanged">
<RowStyle BackColor="#EFF3FB" />
<Columns>
<asp:BoundField DataField="dbID" HeaderText="dbID" Visible="false"
SortExpression="dbID" ReadOnly="true" InsertVisible="False" />
<asp:BoundField DataField="ActID" HeaderText="ActID"
SortExpression="ActID" />
.......Other BoundField were deleted for this post purpose............
<ItemTemplate>
<asp:LinkButton ID="LinkB_ViewActDetails" runat="server"
Text="Edit" CommandName="Select" CausesValidation="false"></asp:LinkButton>
</ItemTemplate>..............

HOWTO create ASP.NET C# controls on server side for posted data that had no runat=server on the client.
I have processes needing to post files to a ASP.NET application. These processes must post without runat=server as such:
<form ~~~~ to some ASP.NET/C#/aspx page>
<input type=file name=MY_FILE ~~~>
</form>
On the ASP.NET page, in the Page_Load I would code somethign like this:
[URL]
Here is the trick, the control "fileLIST_FILE" does not exist because the HTML does not have runat=server on it.
If the client did have runat=server the designer.cs would have somethign liek this:
System.Web.UI.HtmlControls.HtmlInputFile fileLIST_FILE;
With all that said, I want to make "fileLIST_FILE" on the fly inside Page_Load fromt he posted name of "MY_FILE".
do not focus on the fact that this is a file upload. I would like to know how to do this for any posted FORM data.

I'm trying to develope a collapsible panel control with designer.
I have the following two classes:
[Code]....
and this one:
[Code]....
In fact, the designer class is a copy of a sample class in MSDN and I only tried to customize it to work for me. I'm not sure if all methods are necessary or not.
I have the following two questions:
1- When I use this contrl in design mode, I can add or delete controls to it, in the html view, tags are not updated. so when I close the page and open it again, all changes are lost.
2- I have added this control to the same asp.net project that is using this control. Isn't there any way to have this controil in tool box?

Working on a DNN website. Long time VB programmer new to ASP and Web Development.
I have a page with 2 modules on it one to select records and the other to show records details. there is also an add button on the select module for adding new records. the detail module has a tabcontainer with 5 tabs on it and if the user is adding a new record I want to disable the first tab. At all other times I want the user to have access to the first tab. The user clicks a button that uses OnModuleCommunication to start adding the new record. All my code is server side so when they click the button I clear all the fields and enable them all for editing but I have not been able to set the tabcontainers tab to enabled=False
[Code]....
and if it is in the correct location I do not want the button on the page to be seen like it is I want to call it from the server side so the user has no choice.

I have a tricky problem. I am in a situation where I need to use a method defined in a .cs file from a javascript function. The problem is we are using .NET 1.1 and AJAX cannot be used for the application.
Also, I will need to pass a string from the javascript to the server side method. The page where I am implementing the javascript is a .as
I have tried doing a post back and creating a RaisePostBack event handler method (both in the .aspx page and the .ascx user control) but no luck.
The javascript is called from a span's onclick event. The javascript function's input parameter would be a string which I will need to use to instantiate an Attachment.
I created a method which instantiates an Attachment using a string and calls the corresponding Delete() method for the Attachment object.
Now, I will need to pass the string from javascript function to the method I have created. I cannot use PageMethods.
The Javascript function is like:

I have a generated table (after uploading images) and it contains images and I want to select the image and throw the ID back in server side.
