.net - Adding Control To A Panel At Runtime?
Dec 16, 2010
I'd like to add a control A (that exists on a page) to a Footer user control's panel. If I create the control A dynamically and add it, I don't have issues. But I would like to avoid adding this dynamically.So, I defined control A in the aspx page and in the code behind, I got reference to the footer's panel and did a Controls.Add() It works fine, but postbacks from this control has strange behavior (could be due to viewstate?) as it doesn't execute some code that is on the page with a !IsPostback condition

I am converting a web forms site to MVC and there are a lot of pages all with an individual screenshot image on. Rather than have a separate page for each screenshot image, I though a better way to do this would be to have one page, and to pass the image details into a Controller method, and then set the src value of the <img> in my code. Does anybody know how to do this, and even if it is a good idea to be making reference to UI elements in my Controller code?

I need to have a siteMapeNode for a menu control to only show up during development.
The following node would be in the web.sitemap file.
[Code]....
I can either put this node in my web.sitemap file and remove it in release builds.
Or Add the node in debug builds.
Probably done in PreInit or Page_load events.

I'm trying to add some user controls on a page. Thats easy, I just do it like this.
UserControl block = (categoryblock) LoadControl("categoryblock.ascx");
Panel1.Controls.Add(block);
But i want to access the label controls and more that are inside the categoryblock.ascx. How would i do that? I cant do it like this,
block.l_itemName.text = "blabla";
I managed to user FindControl("l_itemName") but i would rather like to have the intellisense.

Am currently working on my first ASP.NET projects. I have a requirement for a page where a user can enter their current address, and then add as many previous addresses as they like. I have created a Panel with the required text boxes in, and also an 'Add' button which will allow them to add another address. How could I make a copy of that Panel and add it to the page at runtime ... assuming that it is possible!!!

I have a Masterpage that has Treeview. You can select some nodes there. Based on the selection you get some items in the Default.aspx's Placeholder, you get a image and a linkbutton placed in a Panel. Like this :
This code is in the Default.aspx that has the Masterpage.
[Code]....
There seems to be problem when i create the controllers at runtime, when the site does a postback, lets say if i click "Enska" in the treeview i get the results in the image above. Lets say that i then click "The Punk Panther" i get a error.
An error has occurred because a control with id 'ctl00$CPH_Main$ctl05' could not be located or a different control is assigned to the same ID after postback. If the ID is not assigned, explicitly set the ID property of controls that raise postback events to avoid this error.
Also, how would i go by making a event handler for the linkbutton at runtime, can i make one event handler that every linkbutton uses or what ? I want the folder and the linkbutton to be clickable and link to the same place, is it simpler to make the whole Panel clickable, if so, how would i get a "OnClick" event on it ?

I have have two radio button lists that need to be mutally exculisve, i.e when one is clicked the other one neesd to be cleared, my further problem is beause they are in a formview I had to add handlers to clear all the controls in the other list when the one is clicked and vice versa. here is the code below Now the code works but one of the testers found that if you click back and forth around twenty times you get the above java error:
Exception message: Maximum request length exceeded
my though here is the handler is being added to many times ? but even if I remove the handler after the process is complete I still get the same error.

to duplicate an already existing <div> with its existing controls multiple times on one form. I have a situation where I have a group of controls contained in one <div>, but the user might need to add more information in the same format so I would like to just have them click a button to add another component and the same set of controls will be duplicated below it.

In my Page_Load() event, I'm calling a Sub (in a module UserMenu.vb) that reads an XML file which has the user menu entries. The final menu should be an <ul> with several <li>, some of them with anidated <ul> within. As I understand, I may use a asp:Panel in my page to position a container for this elements I read and in this sub I try to add them using new BulletedList and new ListElement BList.Items.Add(LItem)), but when I get to Panel.Controls.Add(BList) it throws an error that says BList should be inserted in a Form. Why? Aren't they just <ul> and <li>? What other alternative I have to create <ul> and <li> in a specific part of my page?

I am creating a web application that displays URL to users in a GridView. The application has a code behind that will be doing the processing before it can return me a URL. This is done in a loop. So it looks something like :
[Code]....
What I wanted is to make the Gridview always update the rows everytime an item in the loop is done instead of waiting for the loop to finish.
For now, the application will only display the whole table until the code/loop finishes. I'm very much aware that this will happen because the web page is static in the first place. Does anybody know how to do this?
I have tried of using iframes(I thought of reloading the frame so the whole page wont reload again and a new GridView table would appear because of the code in Page_Load event because I tried placing the data in a separate static class and the GridView.aspx page will just retrieve the values upon every reload)
and I'm not sure how to implement AJAX/Javascript with this. Is Animation involved in this kind of situations?

Basically I have a usercontrol that is setup to capture a persons education details. I want to have a button inside the update that when the user clicks loads the usercontrol below the previous usercontrol.
I have got as far as
UserControl userControl = (UserControl)this.LoadControl(controlName);
this.Panel1.Controls.Add(userControl);
however I am not sure how to keep the orginal usercontrol and not overwrite it with the newly loaded usercontrol.

What I am trying to do here is I want to add the dynamically created labels in the Panel on the Webpage and not directly on the Webpage. My panel has scroll bars and thus when I scroll horizontally or vertically only the background moves whereas the labels are static to the page.
And some labels are even visible on the panel borders on scrollbars (some on the page outside the panel) which are suppose to be placed inside the Panel. So when I scroll either of the ways even the labels should move along with the background image.
So how can I make these labels stick to the Panel and not the Page? How do I do it?

I have a Data Repeater to which I need to add x number of images depending on their existence in the database.
I need the images added within hyperlinks for Javascript functionality. In order to dynamically add the hyperlinks and images I have placed them within a panel in the data repeater and am adding them in the ItemDataBound event.
The problem is that only the first image is being written to the datarepeater.

I have an upload control inside a panel and I am wanting to restrict the file types. I have found the following regExp but I'm unsure where to put it?
ValidationExpression="^(([a-zA-Z]:)|(\{2}w+)$?)(\(w[w].*))(.doc|.PDF|.gif|.jpg)$"
Does this go into the 'ValidationGroup' within the upload button?

I just don't understand how this is done. I've gone through several questions here and from a few other websites.
Basically, a company will be adding process steps, and I want there to be a textbox with a button next to it that reads "Add another step." Once clicked, a new textbox will appear beneath the current one, and the button will be moved next to the new text box. What do I need to do?
