Web Forms :: Mixed Up Values When Using LoadControl To Add Control To UpdatePanel?
Feb 6, 2010
Here is what I am trying to do. I have a page with two link buttons and an updatepanel (the two linkbuttons trigger the updatepanel). I have two usercontrols which have labels with same ID's. When I click the first link button, I add the first usercontrol to the updatepanel and set the label value to datetime.now
if i click the second link button i see that the value of the label from the first control is set in the label in second user control. if the id's are different there is no problem - but in my case the usercontrols are being developed by different teams and I am integrating them in the way i mentioned - so they may have same ids.

I created a user control, then use LoadControl to call the user control in a web form. Everything is working fine on my computer. When my work is copied to another developer's computer, the content of the user control does not show. All other pages are working fine.
The only difference I could think of between my computer and another computer is the other computer use ajax-created master page. But this web form that calls the user control does not use any master page.

I have a dynamically created user control which is accomplished usingLoadControl().
When I debug, the LoadControl call is called once, however the Page_Load inside the user control is called twice. On each occasion, the postback property is false, so it seems somehow the Page_Load event is called outright 2 times and nothing to do with any postback?

I am running into a weird issue. Please follow the comments in the attached code, along with the code.
Basically - I am trying to let a dynamic control class decide on what its javascripts are and what it wants to send to the browser.
But for some reason, this is not working - the javascript is not getting written to the browser page after the post back, even though I see the dynamic control on the browser page.
Here is the code snippet:

<% @
Register

tagname="myControl2"
tagprefix="uc4" %>
Page_Load(object sender,
EventArgs e)
{
myControl2 mc = new myControl2();
//is there anything wrong with the preceding way? Why ever use LoadControl?
Control myLC = LoadControl("myControl2.ascx");
//Why ever do it the LoadControl way?

I'm trying to make a decision about how to display my data. What I have now is a list of products displayed in a repeater. But for code-maintenance I've put my product items in a seperate usercontrol and loading them in a loop with db results using LoadControl.The product control itself is very simple, just a few public properties like title, url, rating but I'm not sure if this will affect my performance. I did some reading here and on forums and some people say it's not the best practice especially if you have more then 20 or 30 of these controls. So, is it really a performance hit using this method or does it stay ok with around 10.000 hits a day.

I have a usercontrol that I load dynamically:
Code:
Sub PageLoadEvent()
Dim ctlIntrotext As Control = LoadControl("tryktabKapacitet.ascx")
plh1.Controls.Add(ctlIntrotext)
End Sub
and then adds the sub to the Page_load, that works fine.However:
1) How do I call subs from the usercontrol?
2) How do I add the OnClick-events which I normally have in the webform source, see example...
Code:
<uc9:TryktabKapacitet ID="TryktabKapacitet1" OnBtnNulstilClick="TryktabKapacitet1_BtnNulstilClick" OnSetAllModulesK="TryktabOptimering1_SetAllModules"
OnSetOneModuleK="TryktabOptimering1_SetOneModule"
OnBtnClick="TryktabOptimering1_BtnClick" runat="server"></uc9:TryktabKapacitet>

Is it possible to LoadControl in windows application? I have email generation as web, but I want to move it to windows service for monthly newsletter.
Emails now are implemented as UserControls, in this way html person can easily modify look & feel.
Current rendering implementation looks like:
StringBuilder sb = new StringBuilder(4000);
StringWriter sw = new StringWriter(sb);
HtmlTextWriter htw = new HtmlTextWriter(sw);
Page page = new Page();
EmailTemplateBase emailCtrl = (EmailTemplateBase)page.LoadControl(
"Controls/EmailTempaltes/Template.ascx");
// Exception here
emailCtrl.DataContext = dataContext;
emailCtrl.Parameter = parameter;
emailCtrl.RenderMode = renderMode;
emailCtrl.DataBind();
emailCtrl.RenderControl(htw);
subject = emailCtrl.Subject;
string MessageText = sb.ToString().Replace(" ", "").Replace(Environment.NewLine, "");
return MessageText;

I'm developing a stand-alone ASP .NET component for dropping in to various sites we create.
Part of the application is a CompositeControl, which needs to load a UserControl.
However, CompositeControl has no LoadControl() method - in stead, I must (as far as I can see?) rely on Page.LoadControl() and this is a problem! How do I know the path to my control, when the page is not part of the assembly?
The page the CompositeControl is situated on resides outside the assembly I am writing the Page.LoadControl() code in, and thus cannot find my .ascx file.
I've tried LoadControl(type, object[]) but this doesn't load the "code infront" file, which I need.
So - how do I find the Path to some .ascx file inside some included assembly (name known, ofc) for my Page.LoadControl? Or, alternatively, is there some other way to load the control from inside the CompositeControl?

I have a repeater that I have bound to a sql reader via my code behind page.
However I can't figure out how to populate the controls in my repeater in my code behind code.
At the moment I am having to specify the database field e.g productprice with the control in the .aspx page like this
<asp:Label ID="LabelUnitPrice" runat="server" Text='<%# Eval("productprice") %>'></asp:Label>
I would rather specify fields in my code behind than embedding them in the .aspx page.
I also have a subtotal label control in my repeater that I would like to populate its text property by mutiplying two of the database values e.g productprice * unitprice shown in my repeater.
I need to do this in code behind, looping through the repeater. Any idea of how I can do this in C#?

I wanted to know if we can pass values from Parent page (in this case from Default.aspx page) to the user control and maintain those values on subsequent "Add/Load" of user control.
So in short, if I click the "Add" button it loads my "webusercontrol" and also I am able to pass my default.aspx dropdownlist value to this dynamically loaded user control and assign it to a "Label or Textbox" which resides in my "webusercontrol", now the problem is that the value doesn't persists! What I meant is , when I click "Add" button again the "webusercontrol" gets loaded again perfectly but now all my "Label's" in webusercontrol has the new selected value from the default.aspx dropdownlist.
So say for instance I have a Dropdownlist in Default.aspx page with Values "Apple, BlackBerry, Nokia" and initial value to be passed is "Apple", I click the "Add" button, now my "Label" inside webusercontrol has the value "Apple", perfect! Next when I click "Add" button again and select a different value to be passed this time say "BlackBerry" now I have 2 webusercontrol loaded on the page, so that means I have 2 "Labels" with different ID's, but now my first Label initially had the value "Apple" because that's what I had passed and now when I passed the value "Blackberry" both the labels of my webusercontrol has the value "BlackBerry" instead of one being "Apple" and another "BlackBerry"
Is there a way to resolve this issue? may be Dictionary List?

We have a webform this is in SSL but it is giving that mixed content message that everything on the page is not covered by SSL. Is this a simple matter of viewing source on the page and tracking down any links that may be pointing to an HTTP site rather than an HTTP site? And if I need these links how do I solve this problem?

I'm working on a web application. One of my co-workers has written some asp.net forms pages. The page classes all inherit from BasePageClass, which of course inherits from the Page class. I wish to add some MVC controllers that I've been told need to use the same logic implemented in the BasePageClass. Ordinarily, I would want to inherit the functions in the BasePageClass in the controller classes, but this breaks the inheritance heirarchy.

In the past I've used UserControls to create email templates which I can fill properties on and then use LoadControl and then RenderControl to get the html for which to use for the body text of my email. This was within asp.net webforms.
I'm in the throws of building an mvc website and wanted to do something similar. I've actually considered putting this functionality in a seperate class library and am looking into how I can do this so that in my web layer I can just call EmailTemplate.SubscriptionEmail() which will then generate the html from my template with properties in relevant places (obviously there needs to be parameters for email address etc in there).
I wanted to create a single Render control method for which I can pass a string to the path of the UserControl which is my template. I've come across this on the web that kind of suits my needs:
[code]....
Does that make sense? I was just wondering if this is at all possible in the first place and how I'd implement it? I'm not sure if it would be possible to map the properties set on 'object' to properties on the loaded user control and if it is possible where to start in doing this?

We use Page.ParseControl to interpret a string of XML into controls. Does it use some kind of caching mechanism? If not - is there a way to cache its result?
Page.LoadControl seems to support some sort of caching.

I have a website that deliveres content from secure source (https://) after the user authenticates. I added a new page where I use an Iframe to display a pdf file. It works fine when I try it from the dev server where I do not get directed from https, but when trying from the actual site I get the error message 'Do you want to view only the webpage content that was delivered securely?' I understand this is because the Iframe source is not secure (the source file is in the root directory of the webpage) Where should I store the content for the Iframe? Can I use a local directory on the server rather than one in the root directory?

I have notice that the UpdatePanel post every field included on the form on every trigger.
But in most of my cases I use 2-3 UpdatePanels at the same page, and each one is independent.
When I click for update the one panel, then my page receive all the input data of the page (ok this is logical) but I won to read only this UpdatePanels data and act according, and not the other panels data.
So I see that a lot of traffic is happened this way.
So is there a way to say to one UpdatePanel - send only my input data, and not everything found on the page. ?

i have a DropDownList, which is inside an UpdatePanel. Now my problem is that, for example, lets say there are 3 item, Item1, Item2, Item3.
Now Item1 is the default, and i have code in codebehind that gets the value of the selected DropDownList, so for example, my code:
string connectionString = ConfigurationManager.ConnectionStrings["PokemonPlanetConnectionStrings"].ConnectionString;
string insertSql = "UPDATE Items SET ItemSelect = @ItemSelect";
using (SqlConnection myConnection = new SqlConnection(connectionString))
{
myConnection.Open();
SqlCommand HubInsert = new SqlCommand(insertSql, myConnection);
HubInsert.Parameters.AddWithValue("@ItemSelect", DropDown1.SelectedValue.ToString());
HubInsert.ExecuteNonQuery();
myConnection.Close();
}
Now the problem is that, once it is in an update panel, when you change the list to another item, so for example, i changed the list to "Item2", it will still be showing the first value of "Item1", i could have used Autopostback to get what i need, but then i wouldnt see the point in using update panel, since i dont want my page to flick.
Is there a way, or code to write that whenever the value of the DropDownList is changed, and i click my button, it will actually get the currently selected value, and not the virst default value,

ASP.NET 3.5 SP 1 Following code in ASPX:
<asp:Button
ID="calcShipping"
UseSubmitBehavior="false"
Text="Calc Shipping Costs"
OnClick="calcShipping_Click"
runat="server"
/>
<asp:Button
ID="submit"
runat="server"
Text="Submit Query"
/>
Renders like this in HTML (I find this to be correct):
<input
type="button"
name="calcShipping"
value="Calc Shipping Costs"
onclick="javascript:__doPostBack('calcShipping','')"
id="calcShipping"
/>
<input
type="submit"
name="submit"

I removed from code the updatepanel and I get the values on page.I also tried conditional updatemode with no success but again I get NO values.
