i have some usercontrols in "~/Pages/"
my URL will be like ~/Default.aspx?p=Login or ~/Default.aspx?p=ContactUser
now i need to get the QueryString("p") and depend of that i want to load my UserControl To the Default.aspx Page
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 DetailsView control bound to an ObjectDataSource within a User Control (.ascx). It appears that the DetailsView.OnDataBound event is being fired on every page load or postback.
I do not see this behavior with a similiar DetailsView directly placed on an aspx page.
How to load usercontrol in (callback or Page methods or Jquery).
View 3 Repliesin my aspx page i have some controls loadded dynamic and other one loaded static, when i am loading the user control dynamically,the dynamic usercontrols loaded successfully, but all static control inside page will be removed! i load the user control using the bellow code inside PlaceHolder. this is my code in aspx page:
[Code]....
I have a Page, that has UserControl1.
UserControl1 has UserControl2.
When the page loads UserControl2's Load event is not fired at all.
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.
<telerik:RadTabStrip
ID="tabMemberDetails"
runat="server"
Skin="WebBlue"
MultiPageID="tabDetails" SelectedIndex="0"
Align="Justify"
ClickSelectedTab="true"
EnableViewState="false"
ReorderTabsOnSelect="true"
Width="1139px"
OnTabClick="tabMemberDetails_Click" ScrollChildren="true">
</telerik:RadTabStrip>
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.

How can I load a usercontrol into a placeholder on the parent page when a button on the currently loaded usercontrol, in thesame placeholder is clicked: I have a page called default.aspx that has a placeholder called placeholder1 on it into which I want to dynamically load a usercontrol I have 2 usercontrols, user1.ascx and user2.ascx user control user1.ascx has a linkbutton, when the linkbutton is clicked, I want the event to load the usercontrol user2.ascx into thesme placeholder, that is placeholder1
View 1 RepliesI have a simple UserControl that I've created that simply allows a user to enter the date. For the time being, it has a single Textbox with ID="tbDate". I am trying to dynamically add this control multiple times via (for example) `placeholder.Controls.Add(LoadControl())` but am receiving the error "An entry with the same key already exists". I could, perhaps, change the ID of the elements but then it would be difficult to grab the value entered by the user.

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!
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.

I am trying to load a usercontrol with its own model, how does this work in practice? What I want really is to click on a button in a View which opens up a UserControl in the center of the page but there will be no sending my model to it because the model used on the page does not contain what I want it to display in the control (More detailed, the page is a memberpage and the uc is an admin page for approving images sent by other members). I've messed around with Inheritance but not really gotten any good results from that perhaps im doing it wrong). This is how it looks today:
The Model
[Code]....
The Controller
[Code]....
The Link
[Code]....
The UserControl
[Code]....
The Error
What can I do differently to make this thing work properly?

View 2 RepliesI 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?
