postback

I'm having a small trouble with ASP.net. I have a small DataTable that i need to be page dependent and also user inaccessible. What i mean is: If i store the data from the DataTable inside a Hiddenfield, the hiddenfield is page dependent (different values for multiple same page requests) but its not user inaccessible since a user can modify its content and then post back. If i store the Datatable in session, that is user inaccessible (which is good) but since some of the content from the page depends on this value, if a user opens the page multiple times (in different tabs) then the session is

(Scroll down to bottom of post to find solution.) Got a asp.net page which contains a Datalist. Inside this datalist, there is a template containing a dropdownlist and each time the datalist is filled with an item, a ItemCreatedCommand is called. The itemCreatedCommand is responsible for databinding the dropdownlist. I think the problem lies here, that I'm using ItemCreatedCommand to populate it - but the strange things is that if I choose the color "green", the page will autopostback, and I will see that the dropdown is still on the color green, but when trying to use it's SelectedIndex, I

I have the tinymce -control as a WYSIWYG-Editior in my asp.net page. When I have e.g. a Text in Bold, after the Postback it is shown as "<p><strong>asd</strong></p>" in the textarea instead of the bolded text. Any ideas? My code: <script type="text/javascript" src="../scripts/tiny_mce/tiny_mce.js"></script> <script type="text/javascript"> tinyMCE.init({ mode: "textareas", theme: "simple", encoding: "xml" }); </script> <textarea runat="server" id="txtareaTextActivity" name="content" cols="48" rows="5"> </textarea> I also had the same problem. But fixed it by decoding the textarea text each time

I am refreshing an UpdatePanel with Javscript by calling a method like so: reloadDropDown = function (newValue) { __doPostBack("DropDown1", ""); selectNewValueInDropDown(newValue); } Inside my UpdatePanel is a <select> box that I need to select an <option> with a newValue . My problem is that my selectNewValueInDropDown method is being called prior to the __doPostBack from completing. Is there a way I can "wait" for the postback before calling my selectNewValueInDropDown method? To make my comment more concrete, here's the idea: reloadDropDown = function (newValue) { var requestManager = Sys

I would like to ask how can i make an html anchor (a element) or even any object to do a postback or to execute an server side method? I want to create a custom button (a wrapped with some divs to do some custom them) and i want to implement OnClick to be look like the ASP.NET LinkButton? Like <a href="#" onclick="RunServerSideMethod()">Just a simple link button</a> Brian Mains By default, controls use __doPostBack to do the postback to the server. __doPostBack takes the UniqueID of the control (or in HTML, the name property of the HTML element). The second parameter is the name of the command

Is there a way to force a postback in code? I'm looking to force the raising of a postback from a method in the c# code behind my asp.net web application. mamoo A postback is triggered after a form submission, so it's related to a client action... take a look here for an explanation: ASP.NET - Is it possible to trigger a postback from server code? and here for a solution: http://forums.asp.net/t/928411.aspx/1 live-love You can try redirecting to same page. Response.Redirect(Request.RawUrl); Simpler: ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), "DoPostBack", "__doPostBack

Here's my problem. I have a hidden field whose value I change through a javascript method. The problem is after postback the value is lost. How can I persist the value after postback? Thanks! .aspx File <asp:HiddenField ID="HiddenField1" runat="server" /> <asp:Button ID="BtnGuardar" runat="server" OnClick="BtnGuardar_Click" OnClientClick="return GridUpdateInfoOK()" /> .js file document.getElementById('<%= HiddenField1.ClientID %>').value = 'TEST'; .aspx.cs file protected void BtnGuardar_Click(object sender, EventArgs e) { String test = HiddenField1.Value; } You don't need to have the hidden

I couldn't find something similar in SO. In ASP.NET, is there any way that on cue I can cause a partial postback with Javascript in an UpdatePanel? I tried __doPostBack() but it does a full postback. I can trick it with a dummy button and fire click() then handle the partial postback that way, but I want a more graceful way than trickery. Thanks. Edit: I found this disturbedbuddha.wordpress.com/2007/11/26/ … but I can't get it to work =( I would love for this method to work; it's perfect for me! So far what I can do using this last method is gain reference to the timer. With the timer
