AJAX :: Load AsyncFileUpload In UserControl Dynamically?
Feb 21, 2011
i put asyncfileupload in usercontrol,and i load this usercontrol dynamically,but uploading process do not works. please help me.how to upload image (usercontrol dynamically) and i show this image after upload.
I want to use same functionality in Ajax:Accordion. Looking for the code for this as well as instead of label in user control i want to bind the grid view.
I have UserControl that has asp control(<asp:Button runat="server" ID="btn" />) and I want to render it. I tried 1
[Code]....
It doesn't works because it says that each control that has runat="server" must be in Form.I also tried 2:Because loader.Form is null, I create HtmlForm and added the ctrl to it and then added HtmlForm to loader's Control, BUT it says that it has 2 HtmlForm. So, instead I "injected" HtmlForm to loader like this [Code]....
Now no error is occurred, BUT StringWriter is empty. don't tell me to add Page to solution and override OnRender. I want to do it as I mentioned above.
When it comes to the usercontrol specially when they are loaded dynamically on the basis of certain conditions then it becomes a very confusing work. I have read in many forums that the dynamic controls have to be loaded in OnpreInit or OnInit. Some of those links are[URL] But this is useful only when if the we know that we have to load UserControl1, UserControl2 without considering any conditions. But what if I have a Tab control and for each Tab Click I have to load the UserControl dynamically. In that situation how can we add the control in either OnPreInit or OnInit. If I am not mistaken then in such case, then we can add usercontrol in certain events. If we are using a TabControl then we load in Tab_Click , if we are using Menu Control then we use Menu_Click and depending upon the particular tab or Menu we load associated usercontrols. Hence in these conditions, how can we go with the logic mentioned by above links. I have this confusion for very long time . I am posting little portion of my project here. I am using RadTabControl but it doesnt matter if it is Microsoft TabControl. In the aspx, I have a code to define RadTabControl.
In the code behind, I am loading usercontrol on the basis of the particular TabClick. tabMeberDetails_Click fires whenever I click on the tabs.ViewState["ControlName"] stores UserControlName on the basis of certain condition and finally i load the usercontrol.
proteced void tabMemberDetails_Click(object sender, RadTabStripEventArgs e) { Conditions...... { ViewState["ControlName"]=........ } viewDef=ViewState["ControlName"] UserControl control = (UserControl)LoadControl("~/Controls/" + viewDef + ".ascx"); after this I add control to the RadTabStrip.................. and call bind method......... }
As you can see from above, I am loading my usercontrol in tabMemberDetails_Click event. I see no other choice to do it in OnPreInit. Can anyone answer if this is the right way to do or there is another way that complies with the logic in the links given above.
I need to insert some JavaScript code inside a UserControl that I load from an Ajax call via jQuery Ui Tabs. Let me explain... This is my View (with jQuery loaded)
<script type="text/javascript"> $(document).ready(function () { $("#tabs").tabs({ cache: false, }); getContentTab (1); }); function getContentTab(index) { var url='<%= Url.Content("~/Home/getUserControl") %>/' + index; var targetDiv = "#tabs-" + index; $.get(url,null, function(result) { $(targetDiv).html(result); }); } </script> <div id="tabs"> <ul> <li><a href="#tabs-1" onclick="getContentTab(1);">Nunc tincidunt</a></li> <li><a href="#tabs-2" onclick="getContentTab(2);">Proin dolor</a></li> <li><a href="#tabs-3" onclick="getContentTab(3);">Aenean lacinia</a></li> </ul> <div id="tabs-1"> </div> <div id="tabs-2"> </div> <div id="tabs-3"> </div> </div> With these lines of code I call the Ajax function to load the content into a DIV. This is the Action from the controller: public ActionResult getUserControl(int num) { return PartialView("TestUC", num); } And this is the UserControl... <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> Number... <span id="testSpan"><%=Model.ToString() %></span>!! <input type="button" value="Click me!!" onclick="message();" /> <script type="text/javascript"> function message(item) { alert($("#testSpan").html()); } </script>
The problem is that the message() function returns always 1 (instead of returning the correct number). My question is... How should I add the script to my UserControl in order to have my code running correctly?
I've stumbled across a strange problem with the AsyncFileUpload control: if the control doesn't exist on the initial load, the UploadedComplete event does not fire. For example, the following code works just fine:
[Code]....
But as soon as the code is wrapped in an if (IsPostBack) condition as shown below, FileUploaded no longer fires, even though the code is otherwise identical:
[Code]....
Would anyone be able to shed some light on why this is happening?
1. I need to add ajax AsyncFileUpload control programtically. How can be it done? If so how can i get all files which need to be uploaded like httppostedfile class is used to get all the files for fileupload control.
2. Can AsyncFileUpload control be casted or conveted to asp fileupload control or html fileupload? If so provide me with code.
I have several usercontrols which are loaded based on business logic.However, all of them have webcontrols whose selected/entered value needs to be accessible in parent page on an event.Since there can be any combination of UserControls, I do not want to load all the UserControls in the Parent Page, since they are heavy.
I would like to load only those controls which are supposed to appear on the page, yet access the value from the usercontrol which caused the postback. (I would rather not access using Request.Form) (ViewState is open, but unsuccessful to store value in parent page's viewstate in onClick)Here is a sample scenario
Page: Home
Dynamically Loads: UserControls1
UserControls has TextBox tb and Button btn, causing onClick
When btn is clicked, I want to get value of tb in parent page on PostBack, Page creates UserControl2
i have a beginners question. I would like to build a website with n areas with usercontrols inside for different actions. For example one usercontrol should show up last n logged in users, or another usercontrol should do a long running operation and should show some calculated information on sales information etc.
Building these controls and the page for this is no problem without AJAX, but how could i make it, that the n single usercontrols load AFTER the base page is loaded with an progress bar like "Loading data. Please wait." and when its finished it should show the information.
How could i make that? I think that this is possible, cause i saw it on several websites.
My first testing was to put two or more updatepanels and in each update one usercontrols. But that didnt work.
my problem is it that i when loaded usercontrol in Updatepanel dynamically,so can not execute javascript or jquery code in second usercontrol.
"EconomicBongah.ascx" UserControl work correctly, because that this usercontrol loaded in Page_Load Event for the first time.
when i click on the btn_Article,"EconomicArticleMarket.ascx" UserControl Get loaded, but with the first user control code will interfere,and therefor Javascript or jquery code in second usercontrol can not execute, and encounter with error in Jquery-1.4.4.js file.
I've a ASP.Net page (Default.aspx) which will load UserControl (ucontrol.ascx) dynamically into an UpdatePanel. By using UpdatePanel, we believe we're able to prevent the entire page to be posted-back.
My problem is, within the UserControl, we have some form controls, such as inputs and buttons; after the UserControl is loaded, clicking on any button inside the UserControl will cause the UpdatePanel to be blanked. During the investigation, I found that, breakpoints within the Button1_Click() in the code-behind for the UserControl is never reached. Please reference to the code below, this references to [REFERENCE]1.
I'm developing an ASP.NET application and I'm trying to do the following:
I'm going to have only one ASPX page splitted into two columns. On the left column is going to be a TreeView, and on the right column is going to be something to edit treeview's nodes.
When the user can select a treeview's node to edit on the right column. Depending on the node's depth fields on right column will vary.
I wondering to use ASCX controls and load on right column dinamically using AJAX, for example. Is there a better choice? Can I do that?
I don't want to reload the entire page when the user wants to edit a treeview's node. Maybe I'm going to need an UpdatePanel on the right column to load dinamically ASCX controls, isn't it?
I am hoping someone can help me out. I have a web application that contains a usercontrol think "employment details" a user can enter a previous employment detail.
I have created a page that contains an update panel a placeholder and a button. The button I want to use to load a new copy of the same usercontrol. Can anyone point me in the right redirect?
I am using ASP.NET 2.0 with VB. In design view of grid, i have one textbox in its template field. I also have one Ajax Calender Extender and FilteredTextBox Extender. I have set target controlId of both calender and filteredtextbox extender equal to that textbox. Now dynamically i dispose one of the extender from that textbox. everything works ok. But once my page reloads it takes the original design image, means both extenders are being set to that textbox.
I have a page with an UpdatePanel with a UserControl in it. That UserControl contains a GridView with a nested UserControl that seems to disappear when the parent UserControl is rebound. I cannot for the life of me figure out why the child UserControl disappears. The code works beautifully on the first load, but any partial postback causes the "Pick" UserControl to disappear.
Here the UserControl is correctyle loaded via http. So what should i do to load it from the same position but via the https protocol (the certificate is already configured)?
I like to build a components collection project so that I can use those components later on other projects. For example I created a UserControl called MyDataGrid.ascx
So suppose the projects layout are something like this:
--> IPGostarProject - Under namespace of IPGostar - contains components and lot's of user controls --> SampleProject - here I want to use MyDataGrid.ascx UserControl from IPGostar namespace.
But as you know LoadControl function only takes virtual directory as it's parameter. So you can't load anything outside the SampleProject directory!
