How to load UserControl at runtime and invoke the methods present in that usercontrol dynamically( at runtime)?
View 4 RepliesI have a Web Form that uses Master Pages. I only tell you this part so you understand the layers.
On the page, I have a web user control. I can see public methods on that user control by simply calling userControlName.PublicMethod();
However, there is a button on this page which generates additional content. This content is based on a placeholder control and adding additional web user controls :
[Code]....
Now, on the main form, I want a submit button that will call a public method of each "subForm" that was added at runtime.
I have tried various forms of Control C = This.Page.Master.FindControl("cpBody").Findcontrol("ctl01")... etc, but can never seen to get the right combination.
Below is a listing of the web form
[Code]....
On my page I have a placeholder where I load a usercontrol when I select an item in dropdownlist.
protected void ddlLoadCtr_SelectedIndexChanged(object sender, EventArgs e)
{
Control userControl = LoadControl("../AleSettings1.ascx");
plchldSettingsControl.Controls.Add(userControl);
}
If I press F5 (IE) after user control was rendered, I get IE's warning window that IE needs to resend the information....
How can I prevent it and why does it happen?
UPDATE:Maybe there is another approach? I want to load specific control (with it's markup) when user selects it from the dropdownlist.
if a postback is made the control shouldn't disappear(only if another control was selected from the dropdownlist) Everything is inside update panel!
In the process of migrating an old VS2003 web app to VS2008, I'm running into this issue and haven't been able to find a resolution. Sample code: "Default.aspx" has a PlaceHolder(ToolHeader). In the Page_Load(), we dynamically load a user control passing in the virtual path to a helper method [public Control ParseUserControl(string virtualPath)]. This reads the content from the physical path, returns
a Control from ParseControl() method. I immediately get the following error when I open the default.aspx page in browser.
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Could not load type 'DynamicUC.UcControl'.
Source Error:
Line 1: <%@ Control AutoEventWireup="true" CodeBehind="UcControl.ascx.cs" Inherits="DynamicUC.UcControl" %>
Can't figure out why it can't load the type. Namespaces are looking right. I try removing the Inherits="DynamicUC.UcControl" attribute from the "ucControl.ascx", it loads the page fine. Also, this control is a simple one and has no code behind. There are others with actual code behind. They won't work if I remove the Inherits attribute.

View 1 RepliesI am having a Calculate() function in user control which is inherited in a page.
I need to call this method in the button click event in the page.
I want to be able to control access to photos and PDF documents at run time.
I want users to be able to download the photos and documents as soon as they pay for them instead of having to wait for me to email the items to them.
What's the best way to do this? I am using VB.net, SQL Server, and ASP.net.
I am entry level to lower-middle in my programming skills, but can usually follow along.
I have two usercontrols usercontrol1 and usercontrol2.
Now I have a hyperlink in usercontrol1 on the click event of which I need to display i.e show usercontrol2(otherwise it is hidden).
So I add Reference to usercontrol2 as in code give below:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Rehabilitation.ascx.cs" Inherits="SlumManagement.Web.UC.Rehabilitation" %>
<%@ Reference VirtualPath="RRules.ascx" %>
Now RRules.ascx is usercontrol2.
Now the problem is that after adding reference I only get to access on the server side not Client side.
Once I get a reference to it on the client side I want to do something like this:
function displayctrl()
{
var ctrl = document.getElementById('usercontrol2');
ctrl.style.display = "block";
}
How can I be able to do this?
I'm currently working on a web site which involves a data upload process. The file is currently uploaded to the server method is called (in app_code) where ultimately a DTS package is called (via a web method) to load the data into a database and perform some validation on it.The client has specified that they don't want to have to wait for the DTS package to execute (execution time is less than 5 minutes) so it appears that I need to call the method asynchronously. The user will probably logout or close the browser window while this task is running so I believe I'm unable to run this on an asp.net thread.

View 3 RepliesI am implementing web service into my web application, i added web reference to my application of required web methods from my asmx file.
i am able to create object of this weservice and able to see all the web methods available from the reference object. In debug mode(working environment), i could invoke and get result from the webmethod and working fine as expect. i created test page for testing this.
But, when i deploy same in my beta i am getting below error.(my both test page and asmx file available in my beta server where i deployed)

I have a web service method in .net as below:
[WebMethod(Description = "Adds two numbers", MessageName = "AddMessage")]
public string Add(string x)
{
string retVal = x;
string fileLoc = @"D:KumareshCreateFile.xml";
StreamWriter sw = new StreamWriter(fileLoc);
sw.WriteLine(retVal);
HttpResponse response = HttpContext.Current.Response;
response.Redirect(http://www.google.co.in", true);
sw.Close();
return retVal;
}
I deployed my webservice in IIS server. I have created another .net application, and called the webservice method from the new application. My problem is I am unable to redirect to the specified link[google.co.in]. I am getting the following error: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Web.HttpException: Response is not available in this context. at System.Web.UI.Page.get_Response() Sometimes I get the error as: "Object moved here". "here" is shown as a hyperliink, If I click here, i am redirected to the specified link.
so I have this custom user control, just some data inside divs with a fancy css.
So inside my page I need to add it multiple times, and I do so in code behind within loop.
Now, this code doesn't work

and of course it works fine now. My questions would be - why? can I do it without pecifying file name and just creating control the normal way like in first example?:S

Just for practice purpose I have created one class called MathFunctions like below:
namespaceCSHWEB
{
public
class
MathFunctions
{
public
double
SimpleInterest(double
PrinicipalAmount, double
TimePeriod, double RateOfInterest)
{
return
(PrinicipalAmount * TimePeriod * RateOfInterest) / 100.0;
}
}
}
Now,
how can I invoke above method SimpleInterest with its parameters without instantiating the class?
I would like to load UserControl dynamically from DLL in the bin directory.
The dll contains several usercontrols which dynamically create webcontrols within them.
I do not have Virtual Path of the UserControls to use in LoadControl(String virtualpath) and LoadControl(Type, object[]) does not work(why the heck is it there in the first place anyways).
provide me some sample code which takes either the path of dll or assembly name "ServerControls" to load usercontrol "UserControl1" dynamically into placeholder "PlaceHolder1"
I was wondering if it is possible to upload the .ascx and .ascx.vb of a custom usercontrol into my project directory at runtime via an upload control and then after that use through a database query point my page to load that newly uploaded control via (LoadControl(<newlyUploadedControl>)?
